Dogs (Canis familiaris) as sentinels for determining the risk of occurrence of Rickettsia spp. and Anaplasma phagocytophilum in previously undiagnosed areas.

Determining the occurrence of Rickettsia spp. and Anaplasma phagocytophilum in municipalities with no case records is important to define surveillance strategies and is essential to reduce lethality in different regions. Therefore, an approach aimed at enhancing surveillance in municipalities with an unknown epidemiological situation was tested, according to the classification suggested by Resolution SMA/SES 07/01/16. Canine sera collected in the annual anti-rabies campaign were submitted to the indirect fluorescent antibody test for Rickettsia amblyommatis, R. belli, R. parkeri, R. rickettsii and A. phagocytophilum. Titers ≥1:64 and ≥1:320 were considered positive for Rickettsia spp. and A. phagocytophilum, respectively. For Rickettsia spp., 61.8% of dogs were seropositive, with 26% positive for more than one species, and 42.3% were seropositive for R. rickettsii. Dogs from the urban area presented 5.16 (CI 1.18; 7.69) times greater odds of seropositivity for R. parkeri (p = 0.037) and 3.39 (CI 1.04; 3.70) times greater odds for R. belli (p = 0.017). Considering the 1:40 cutoff point, 19.1% of dogs were reactive for A. phagocytophilum. Two (1%) dogs in rural areas were positive (titer 1:640). The results indicate all species ever tested in Lavras/MG, since the present study is the city's first report on the subject. According to classifications of the aforementioned Resolution, the results determine that the municipality of Lavras should be considered a "risk area" for Brazilian spotted fever(BSF). The methodology presented is efficient, straight forward to perform and inexpensive for diagnosing a risk situation for BSF and human granulocytic anaplasmosis. Moreover, its use can be applied throughout Brazil and other countries as a public health alert guideline.

Temporal relationship between human and canine visceral leishmaniasis in an urban area in southeastern Brazil: An application of the ARIMAX model.

Visceral leishmaniasis (VL) is a neglected disease of public and animal health importance. With the urbanization of the disease, there is evidence of a temporal correlation between the occurrence of human (HVL) and canine (CVL) visceral leishmaniasis, usually with cases in dogs preceding those in humans. In this context, the objective of this study was to develop a time series model suitable for canine-human transmission of Leishmania infantum. Monthly cases of HVL and CVL from 2006 to 2018 in Belo Horizonte, Minas Gerais, Brazil, were evaluated, and monthly health indicators were calculated for HVL and CVL, i.e., incidence coefficient (HVL_IC) and proportion of seropositive dogs (PSD), respectively. The temporal relationship was evaluated using an autoregressive integrated moving average with exogenous variable (ARIMAX) model for two different periods (January 2006-August 2013 and September 2013-December 2018). During the 13 years studied, 1115 new cases of HVL and 103,358 dogs seropositive for CVL were recorded. HVL_IC and PSD exhibited decreasing trends throughout the first study period (January 2006-August 2013). According to the ARIMAX model adjusted for this period, there was a temporal relationship between HVL_IC and PSD, with HVL_IC being influenced by HVL_IC for the last two and five months and by PSD for the third previous month. For the second study period (September 2013-December 2018), it was not possible to fit an ARIMAX model. This study highlights the improvements made by VL surveillance since 2006 in Belo Horizonte and contributes to a better understanding of the epidemiology of the disease by public health policy-makers, doctors and veterinarians involved in the prevention and control of zoonoses.

Giardiasis in children and dogs, and the first report of assemblage E in dogs from northeastern Brazil.

Diagnosis is crucial for controlling giardiasis. We determined the prevalence and genetically characterize isolates of Giardia duodenalis of children and dogs from rural communities in northeastern Brazil. G. duodenalis cysts were concentrated by centrifugal flotation/sedimentation. Molecular characterization was carried out using the loci ssu-rRNA, bg, tpi, and gdh. By parasitological techniques, Giardia spp. infection was detected in 72/192 children (37.5%; 95% CI: 30.6%-44.7%) and 24/139 dogs (17.3%; 95% CI: 11.4%-24.6%). By molecular analysis, infection was detected in 60/141 children (42.5%; 95% CI: 34.3%-51.2%) and 26/92 dogs (28.3%; 95% CI: 19.4%-38.6%). The total prevalence of giardiasis was 54.9% in children (106/193; 95% CI: 47.1%-61.6%) and 32.9% in dogs (47/143; 95% CI: 25.2%-41.2%). Zoonotic assemblages A and B of G. duodenalis were detected in children, and assemblage E of G. duodenalis was detected in one child and two dogs. Parallel use of parasitological and molecular techniques proved to be a more effective strategy for detecting giardiasis in children and dogs from endemic areas.

Factors associated with consumer perception and conduct toward certified beef from Brazil.

The aims of this study were to establish a relationship between consumers' socioeconomic aspects, key meat attributes, and consumer perception and conduct toward traced beef in Brazil. The authors applied a structured form in 52 supermarkets in eight Brazilian cities, through interviews with 2.949 consumers, in 2012. Federal or state inspection stamp was the attribute that most influenced the consumers' purchase decision (14.1%). Most of the interviewees (57.3%) had never heard about bovine traceability. Among those who had heard about bovine traceability, 63.2% would be willing to pay more for beef with certified origin. Consumers with higher education and income had a better knowledge about this type of certification, as well as older consumers, and therefore they would be willing to pay more for certified beef. This research suggests that educational level was the reason that most influenced Brazilian consumers during beef purchase.

Seroepidemiology of Toxoplasma gondii in Dairy Cows in Southeastern Brazil: Seropositive Cows on All Farms Investigated.

PURPOSE: This study aimed to estimate the prevalence and identify the risk factors associated with the higher in-herd T. gondii seroprevalence in dairy cows in 37 farms in southern Minas Gerais, Southeastern Brazil. METHODS: Serum samples from 1,105 dairy cows were subjected to an indirect fluorescence antibody test (IFAT 1:64) for anti-T. gondii IgG. The association existing between possible risk factors at the herd level and the seroprevalence were verified through Generalized Estimating Equation (GEE) multiple logistic regression models. RESULTS: Anti-T. gondii antibodies were observed in 31.4% of the cows (347; 95% CI= 28.7-34.2) and on 100% of the farms (37; 95% CI= 90.6-100.0%), indicating that all properties possessed at least one seropositive animal. For univariate analysis, herds with seroprevalence were categorized as greater and less than 30% as the outcome. The "breeding of Holstein Friesian cows" (p= 0.016, OR= 6.667, 95% CI= 1.500-29.628) and in an "intensive system" (p= 0.013, OR= 6.120, 95% CI= 1.394-26.876) increased the chance of the herd seroprevalence being greater than 30% by approximately six-fold. However, these variables did not exhibit a significant association (p >0.05) in the Generalized Estimating Equations (GEE) logistic regression model. CONCLUSIONS: The results demonstrate that T. gondii infection is widespread among dairy cows in the south of Minas Gerais, with a wide environmental dispersion of the parasite on farms in this region.

Análise físico-quimica e microbiológica de amostras de mel comercializadas no município de Juiz de Fora-MG / Physical-chemical and microbiological analysis of honey samples marketed in the municipality of Juiz de Fora-MG

O mel é um produto obtido das abelhas melíferas contem altas quantidades de monossacarídeos, como a glicose e a frutose, sendo considerado um alimento de alto valor nutricional. Devido seu alto valor comercial, grande parte do mel comercializado não tem sua qualidade preservada. O trabalho teve o objetivo avaliar amostras de mel comercializadas na cidade de Juiz de Fora-MG através de análises físico-química e microbiológica. Das onze amostras analisadas: três apresentaram umidade acima de 20% permitido pela legislação; cinco amostras foram positivas para o Teste de Lugol; cinco foram reprovadas no teste de Lund por apresentarem baixa quantidade de albuminóides e duas amostras apresentaram positividade na análise de Fiehe. Na análise microbiológica não ocorreu crescimento de coliformes totais, termotolerantes, bolores e leveduras. O consumidor deseja um produto seguro e de boa qualidade. Os resultados reforçam a necessidade do controle do comércio e a conscientização dos consumidores.

Seasonal variation and persistence of tungiasis infestation in dogs in an endemic community, Bahia State (Brazil): longitudinal study.

Tungiasis is a zoonosis neglected by authorities, health professionals, and affected populations. Domestic, synanthropic, and sylvatic animals serve as reservoirs for human infestation, and dogs are usually considered a main reservoir in endemic communities. To describe the seasonal variation and the persistence of tungiasis in dogs, we performed quarterly surveys during a period of 2 years in a tourist village in the municipality of Ilhéus, Bahia State, known to be endemic for tungiasis. Prevalence in dogs ranged from 62.1% (43/66) in August 2013 to 82.2% (37/45) in November 2014, with no significant difference (p = 0.06). The prevalence of infestation remained high, regardless of rainfall patterns. Of the 31 dogs inspected at all surveys, period prevalence was 94% (29/31; 95% CI 79.3-98.2%) and persistence of infestation indicator [PII] was high (median PII = 6 surveys, q1 = 5, q3 = 7). Dogs < 1 year of age had a higher mean prevalence of 84.5%, as compared with 69.3% in the older dogs. No significant difference was found between the risk of infestation and age or sex (p = 0.61). Our data indicate that canine tungiasis persisted in the area during all periods of the year. The seasonal variation described in human studies from other endemic areas was not observed, most probably due to different rainfall patterns throughout the year. The study has important implications for the planning of integrated control measures in both humans and animal reservoirs, considering a One Health approach.

Spatial and temporal relationships between human and canine visceral leishmaniases in Belo Horizonte, Minas Gerais, 2006-2013.

BACKGROUND: Visceral leishmaniasis is a serious public health problem in Brazil, and control of this disease constitutes a major challenge. The purpose of this study was to assess the existing spatial and temporal relationships between cases of canine visceral leishmaniasis (CanL) and human visceral leishmaniasis (HVL) recorded in Belo Horizonte, State of Minas Gerais, from 2006 to 2013. METHODS: Data provided by the Belo Horizonte Health Services regarding the disease control routine were analyzed in order to perform a retrospective observational and ecological study. Information regarding the incidence rate of HVL and canine seroprevalence was examined in relation to control actions performed atthe 148 coverage areas of healthcare centers for the period between 2006 and 2013. A time series analysis was performed using the Gretl 1.9.12 software followed by the assessment of the existing increasing or declining trend and seasonality in the occurrence of CanL and HVL. Autoregressive integrated moving average (ARIMA) models were adjusted, intervention analysis was performed, vector autoregressive models were developed, and Granger causality was used for testing temporal relationships between variables. The hot spot analysis tool was used for cluster identification through Getis-OrdGi statistics. The ArcGis for desktop 10.2.1 software was used for spatial analysis. RESULTS: We identified 866 HVL cases in Belo Horizonte between 2006 and 2013. The mean proportion of canine seroprevalence (PCP) was 7.31% and the mean proportion of monitored hosts (PMH) was 6.73%.HVL and PCP showed a decreasing trend, while PMH increased over time (P<0.05). Vector Autoregressive (VAR) and Granger analysis showed a temporal relation between CanL and HVL cases. Maps illustrating the spatial distribution of cases and obituaries of HVL and CanL cases also showed an apparent association between the occurrence of leishmaniasis in humans, and data about canine cases recorded in the previous years. CONCLUSIONS: Cases of HVL were preceded by PMH and PCP cases. Similar results were observed for intraspecific cases (i.e. between PCP and other canine cases and between HVL and other HVL cases), which indicated the existence of favorable environmental conditions for the transmission and spread of L. infantum in Belo Horizonte.

Economic evaluation and efficacy of strategic-selective treatment of gastrointestinal parasites in dairy calves.

In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria established previously by the researchers. Calves in the CT were treated according to the opinion of the veterinarian of EF-UFLA. For statistical analysis, the frequency (%) of fecal samples with count of eggs per gram of feces (EPG) ≥300, count of oocysts per gram of feces (OoPG) ≥500 and fecal samples with count of cysts of Giardia spp. ≥1 were conducted. The overall average frequency of fecal samples with EPG ≥300, OoPG ≥500 and Giardia spp. cysts ≥1, respectively, was similar (p >0.05) between S-ST (20.3%; 17.3%; and 31.5%) and CT (26.4%; 23.9%; and 37.3%). The effective operational cost, per animal, in 12 months, was of R$ 784.58 (US$ 241.41) and R$ 83.90 (US$ 25.81) in S-ST and CT, respectively. The S-ST requires adjustments to be used as a technically efficient and economically viable alternative for the control of gastrointestinal parasitosis in female Holstein calves.

Resumo Na Fazenda Experimental da Universidade Federal de Lavras (FE-UFLA), Minas Gerais, Brasil, no dia do nascimento, bezerras da raça holandesa foram sorteadas de forma aleatória para compor um dos dois grupos, formados por 15 animais cada: Tratamento Estratégico-Seletivo (TE-S) ou Tratamento Convencional (TC). No TE-S, as bezerras foram tratadas após exames coproparasitológicos de acordo com critérios previamente estabelecidos pelos pesquisadores. No TC, as bezerras foram tratadas conforme orientação do veterinário da FE-UFLA. Em ambos grupos, as bezerras foram monitoradas a cada 14 dias, do nascimento até os 12 meses de idade, por meio de exames coproparasitológicos. Para análise estatística, considerou-se a frequência (%) de amostras fecais com contagem de ovos por grama de fezes (OPG) ≥300, contagem de oocistos por grama de fezes (OoPG) ≥500, e amostras fecais com contagem de cistos de Giardia spp. ≥1. A frequência média global de amostras fecais com contagem de OPG ≥300, OoPG ≥500 e cistos de Giardia spp. ≥1, respectivamente, foi similar (p >0,05) entre TE-S (20,3%; 17,3%; e 31,5%) e TC (26,4%; 23,9%; e 37,3%). O custo operacional efetivo, por animal, em 12 meses, foi R$ 784,58 (US$ 241.40) e R$ 83,90 (US$ 25.81) para TE-S e TC, respectivamente. O TE-S necessita de ajustes para que possa ser indicado como uma alternativa, tecnicamente eficiente e economicamente viável, no controle das parasitoses gastrointestinais em bezerras leiteiras.

Canine tungiasis: High prevalence in a tourist region in Bahia state, Brazil.

Tungiasis is a parasitic skin disease neglected by authorities, health professionals, and the general population. Its occurrence is significantly associated with poverty. A cross-sectional study was conducted to describe the prevalence of tungiasis, associated clinical signs and risk factors of the canine population at a tourist site in the city of Ilhéus, Bahia (northeast Brazil). All village households were visited and dogs inspected after authorization by owners. A semi-structured questionnaire was administered. Of the 114 dogs included in the study, 71 (62.3%) were infested; all of them had lesions on their pads. An ectopic lesion on the nose was observed in one dog (1.4%). The number of manipulated lesions outnumbered the number of vital and avital lesions with an average of 88.3%. Edema (95.8%) and hyperkeratosis (85.9%) were the most prevalent clinical signs. Behavioral disorders such as excessive licking (6/71; 8.5%), disobedience (1/71; 1.4%) and prostration (2/71; 2.8%) were reported. In the multi-variate analysis, semi-restricted condition of the dogs (adjusted OR=8.58; 95% CI=2.47-29.76) and the presence of sand on the compound (adjusted OR=14.23, 95% CI=2.88-70.28) were significantly associated with infestation. We concluded that, infestation with Tunga spp. is highly endemic in the canine population of the village. The low level of restrictions on dogs and the presence of sand in areas most frequented by the animals are perpetuating factors of infestation in the community, subject to integrated and multidisciplinary intervention measures.

Seroepidemiology of Sarcocystis neurona, Toxoplasma gondii and Neospora spp. among horses in the south of the state of Minas Gerais, Brazil.

The present study used the indirect fluorescent antibody test (IFAT) to determine the seroprevalence of Sarcocystis neurona, Toxoplasma gondii and Neospora spp., and evaluated the variables associated with these infections among 506 apparently healthy horses, reared in the south of the state of Minas Gerais, Brazil. This study was conducted between April 2012 and October 2013. Among the horses, the true prevalence of S. neurona was 26% (95% CI: 22.0-30.4%), T. gondii 19.9% (95% CI: 15.5-24.8%) and Neospora spp. 23.9% (95% CI: 19.9-28.1%); and among the farms, 88.3% (95% CI: 74.4-91.6%), 71.6% (95% CI: 41-92.8%) and 85% (95% CI: 70.7-96.1%), respectively. Regarding mixed infection, 17 horses (3.4%) were seropositive for both S. neurona and T. gondii, 16 (3.2%) for T. gondii and Neospora spp. and 14 (2.8%) for S. neurona and Neospora spp. The associations between seropositivity and variables relating to the structure of the farm, management and health were analyzed using the logistic regression analysis, through the generalized estimating equations (GEE). The results suggest that the south of Minas Gerais is an enzootic area for S. neurona, T. gondii and Neospora spp. among horses, with prevalence of asymptomatic subclinical or chronic infections.

Resumo Este estudo determinou, pela reação de imunofluorescência indireta (RIFI), a soroprevalência de Sarcocystis neurona, Toxoplasma gondii e Neospora spp., e avaliou as variáveis associadas com a infecção, em 506 equinos, aparentemente sadios, criados no Sul de Minas, Brasil. O estudo foi realizado no período de abril de 2012 a outubro de 2013. Entre equinos, a prevalência verdadeira para S. neurona foi de 26% (IC 95%= 22,0-30,4%); para T. gondii de 19,9% (IC 95%= 15,5-24,8%); e para Neospora spp. de 23,9% (IC 95%= 19,9-28,1%); e entre propriedades, 88,3% (IC 95%= 74,4-91,6%), 71,6% (IC 95% = 41-92,8%), e 85% (IC 95%= 70,7-96,1%), respectivamente. Em relação à infecção mista, 17 (3,4%) equinos foram soropositivos para S. neurona e T. gondii, 16 (3,2%) para T. gondii e Neospora spp., e 14 (2,8%) para S. neurona e Neospora spp. A associação entre soropositividade e variáveis relacionadas à estrutura da propriedade, manejo e sanidade, foi analisada, utilizando-se a análise de regressão logística estimada por Generalized Estimating Equations (GEE). Os resultados sugerem que o Sul de Minas é área enzoótica para S. neurona, T. gondii e Neospora spp. em equinos, com predomínio de infecções subclínicas ou crônicas, assintomáticas.

Prevalence and risk factors of Theileria equi infection in horses in Minas Gerais, Brazil.

Theileria equi, a protozoon in the phylum Apicomplexa, is the causative agent of equine theileriosis. The aim of this cross-sectional study was to determine the prevalence of IgG antibodies against T. equi, by using the indirect fluorescent antibody test (IFAT) reaction and correlating the serostatus with some epidemiological variables relating to the way in which Mangalarga Marchador horses are raised in southern Minas Gerais, Brazil. In this study, 506 horses were used, all clinically healthy, on 53 horse farms distributed across 27 municipalities in southern Minas Gerais. The statistical tests, comprising the chi-square test and generalized estimating equations (GEE), were performed in the SPSS Statistics 20.0 software. The true seroprevalence of T. equi among the horses was 57.0% (288 out of 506; ranging from 52.1 to 62.0%) and among horse farms, 98.1% (52 out of 53; ranging from 90.3 to 99.9%). The horse farms on which the majority of the horses presented good body condition and which did not use chemical products to kill ticks when new horses were introduced, had horses over the age of 5years, comprised <100ha in area and did not use embryo transfer showed greater seroprevalence of T. equi (p<0.05). The results from this study make it possible to state that infection with T. equi is endemic in the south of Minas Gerais and is widely distributed among horse farms raising Mangalarga Marchador horses. However, these infections are subclinical or chronic.

Inspection of the actions of veterinarians qualified to act in the National Programme for Control and Eradication of Animal Brucellosis and Tuberculosis / Fiscalização das ações de médicos veterinários habilitados para atuar no Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose Animal

The inspection of qualified professionals is an important action of the National Programme for Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT). The data for this study were obtained by compiling reports of 63 inspections in loco of qualified private veterinarians between 2008 and 2011 in the state of Espírito Santo, Brazil. Through the findings of this study, it was observed that all inspected professionals are regularly registered in the CRMV-ES, nevertheless it was found pending issues regarding the registration to conduct vaccinations against brucellosis. It was observed that most professionals keep the infrastructure and equipment for conducting tuberculosis and brucellosis tests. The majority adopts the official models of certification, however there is a significant delay in sending reports of actions, and many professionals reported a lack of demand for certification of properties.(AU)

A fiscalização de profissionais habilitados é uma importante ação do Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose Animal (PNCEBT). Com este trabalho, buscou-se reunir informações das fiscalizações relativas à habilitação de médicos veterinários privados no estado do Espírito Santo. Os dados deste estudo foram obtidos mediante a compilação dos relatórios de 63 fiscalizações in loco entre 2008 e 2011. Por meio dos achados deste estudo, observou-se que todos os profissionais fiscalizados estão regularmente inscritos no CRMV-ES, todavia foram verificadas pendências quanto ao cadastro para realizar vacinações contra brucelose. Observou-se que a maior parte dos profissionais mantém a infraestrutura e os equipamentos para a realização de exames de brucelose e tuberculose. A maioria adota os modelos oficiais de atestados, contudo há um expressivo atraso no envio dos relatórios de ações, e muitos profissionais relataram falta de demandas para certificação de propriedades.(AU)

Fatores socioeconômicos que influenciam na disposição de consumidores em adquirir carne bovina com certificação de origem em Belo Horizonte, Minas Gerais, Brasil / Socio-economic factors affecting the consumer provision in meat with certification of origin Belo Horizonte, Minas Gerais, Brazil

Objetivou-se verificar a influência dos fatores socioeconômicos na disposição de 407 consumidores em hipermercados do município de Belo Horizonte, Minas Gerais, em adquirir carne bovina com certificação de origem e verificar as características inerentes ao produto que auxiliam o consumidor no momento da compra, considerando o seu conhecimento prévio sobre rastreabilidade e certificação de origem. Foi realizada uma análise descritiva de todas as variáveis e, posteriormente, realizada a análise univariada pelo teste do qui-quadrado ou exato de Fischer. As variáveis foram adicionadas no modelo múltiplo da regressão logística Generalized Estimating Equations (GEE) e para todas as variáveis presentes no modelo final (p ≤ 0,05) foi calculado o risco por meio da odds ratio (OR) ajustada a um intervalo de confiança de 95%. Todos os fatores socioeconômicos analisados (sexo, idade, renda e escolaridade) influenciaram na disposição de consumidores em adquirir carne bovina com certificação de origem. Os atributos intrínsecos mais importantes na tomada de decisão no momento da compra da carne foram cor, maciez, odor e a pouca quantidade de gordura; enquanto que os atributos extrínsecos foram preço, selo de qualidade e carimbo do SIF. A maioria dos consumidores conhece o conceito correto de rastreabilidade e acreditam que o maior benefício da carne rastreada é oferecer mais segurança e evitar riscos de doenças transmitidas pelos alimentos; e a desvantagem é ser um produto mais caro do que o convencional.(AU)

The present study aimed to verify the influence of socioeconomic factors in the provision of 407 consumers in supermarkets in the city of Belo Horizonte, Minas Gerais, Brazil, in purchasing beef with certification of origin and to verify the inherent characteristics of the product that help the consumer at the time of purchase, considering their prior knowledge about traceability and certification of origin. A descriptive analysis of all variables was performed and a univariate analysis was subsequently conducted by chi-square test. The variables were added in the multiple logistic regression model Generalized Estimating Equations (GEE), and for all variables in the final model (p ≤ 0.05) the risk was calculated by the adjusted odds ratio (OR) to a range of 95% confidence. All socioeconomic factors examined (gender, age, income and education) influence the willingness of consumers to purchase beef with certification of origin. The most important intrinsic attributes in decision making when buying meat were the color, softness, odor and little amount of fat, whereas the extrinsic attributes were price, quality seal and stamp of the SIF. Most of the consumers know the correct concept of traceability and believe that the greatest benefit of the traced meat is to be safer and to avoid the risk of foodborne illness; and the disadvantage is to be a more expensive product than the conventional.(AU)

Analysis of poultry transit, notification systems and legislation in the state of Sergipe, 2008-2012 / Análise do trânsito de aves, dos sistemas de notificação e da legislação no estado de Sergipe entre 2008 e 2012

The purpose of this study was to assess the transit of poultry, as well as the inspection on the outbreak of diseases, by addressing the issues concerning the system of the National Program on Poultry Sanity and its legal resolutions. The data on the animal transportation and the occurrence of the diseases were collected from the official services. A legislation-based assessment was also carried out for the period from 2008 to 2012 in the state of Sergipe, Brazil. Results showed an intense transit of poultry in just about all towns of the state in the period under study, especially in chicken farms where less number of poultry is bred: from 5,000 to 15,000. Besides, 64% of poultry transportation was found to be intermunicipal. The state of Sergipe has received poultry particularly from the states of Pernambuco (49.87%), Bahia (20.85%), Minas Gerais (5.94%), Paraíba (5.16%), and Goiás (5.05%). The number of transit indicates an increase in transit over the years. In addition, three of six municipalities which saw these diseases (Estância, São Cristóvão and Itaporanga d'Ajuda) are responsible for a great part of the poultry transit. Results also showed that the majority of activities of the State Program on Poultry Sanity would be carried out in the municipalities where a larger poultry marketing flow takes place, thereby seeking to record a greater number of notifications on the diseases and, then, carry out the surveillance activities. Therefore, regarding the poultry transit, it is recommended to do a mapping of the risk regions for poultry diseases, as well as studies about the epidemiological characterization of the municipalities of the state of Sergipe.(AU)

O objetivo deste estudo foi avaliar o trânsito de aves, sua fiscalização e o surgimento de enfermidades, abordando questões referentes ao sistema do Programa Nacional de Sanidade Avícola e suas determinações legais. Dessa forma, compilaram-se dados do serviço oficial sobre o trânsito dos animais e a ocorrência de doenças, realizando-se também uma avaliação da legislação vigente entre 2008 e 2012, no estado do Sergipe. Observou-se no período averiguado um intenso trânsito de aves em quase toda a totalidade dos municípios, principalmente entre granjas que alojam pequenas quantidades de aves (5.000 a 15.000), e 64% do total do transporte de aves ocorreu entre municípios do Estado. Os estados fornecedores de aves para Sergipe foram sobretudo Pernambuco (49,87%), Bahia (20,85%), Minas Gerais (5,94%), Paraíba (5,16%) e Goiás (5,05%). O número de guias de trânsito emitidas aponta um crescimento do trânsito ao longo dos anos. Verificaram-se que três municípios (Estância, São Cristóvão e Itaporanga d'Ajuda), dos seis acometidos por enfermidades, são aqueles responsáveis por grande parte do trânsito realizado. O estudo mostrou que para os municípios sergipanos, nos quais acontece maior fluxo de comercialização avícola, seriam indicadas mais das ações do Programa Estadual de Sanidade Avícola, com a finalidade de registrar maior número de notificações de enfermidades e, consequentemente, exercer ações de vigilância. Assim, quanto ao trânsito animal, recomendam-se a adoção de um mapeamento das regiões de risco sanitário para as enfermidades de aves e a realização de estudos sobre a caracterização epidemiológica dos municípios de Sergipe.(AU)

Analysis of time series of cattle rabies cases in Minas Gerais, Brazil, 2006-2013.

Vampire bats are potential transmitters of rabies in rural areas. Cattle rabies is relevant in the state of Minas Gerais due to the increasing cattle herds and geographical features of the area, which are favorable to bat populations. This study evaluated the occurrence of rabies in state cattle by analyzing the time series of monthly values, 2006-2012, describing some aspects of the areas and species affected. The study also pointed out the disease prediction for January-December 2013. We used monthly data of cases reported to the Continental Epidemiological Surveillance System (SIVCONT) of the Ministry of Agriculture, Livestock, and Supply (MAPA), January 2006-March 2013. We also collected data on municipalities and other animal species affected by rabies for a descriptive analysis of the disease. The results indicate that cattle rabies is endemic in the State, with different intensities in different regions. The variables frequency of notifications and bat shelters had a positive and regular correlation (P = 0.035; r = 0.567) between them. With respect to data series, there was a fluctuation of the number of cases (5 to 29 cases per month) over 2006 and 2013, without trend or seasonality, although there would visually appear to be a downward trend. The results also suggest that the forecasting method is suitable for predicting future cases. Bovine species had the highest number of reporting, with 1007 cases (88.88 %), followed by equine species with 112 (9.89 %). The information provided by this study may help understand disease occurrence and find the most effective measures for rabies control in endemic areas.

Fatores associados à percepção e atitude de consumidores de carne bovina com certificação de origem / Factors associated with perceptions and attitude of consumers of meat with certification of origin

O objetivo deste estudo foi verificar quais fatores socioeconômicos estão relacionados com a decisão de compra de carne comcertificação de origem, além de levantar o perfil de percepção e atitude dos consumidores de carne bovina em São Luís/MA.Foi realizada a descrição das variáveis e construído um modelo múltiplo Generalized Estimating Equations (GEE) de regressãologística visando a identificar possíveis associações entre as características socioeconômicas dos consumidores e os principaisatributos da carne que influenciam a decisão para sua compra levantada por meio das entrevistas entre 400 entrevistados no mêsde março de 2012. O selo de qualidade na aquisição da carne foi o atributo que mais influenciou (32,5%) a decisão de comprados consumidores. A maioria dos entrevistados (68,7%) nunca ouviu falar sobre rastreabilidade bovina. Dentre os que já ouviramfalar, a maior parte (71,2%) está disposta a pagar mais pela carne com certificação de origem, apesar de considerar que hádesvantagens associadas à rastreabilidade, principalmente em relação ao aumento no preço da carne. Consumidores com maiorgrau de escolaridade apresentam 2,62 mais chances de já terem ouvido falar em carne rastreada e 1,90 mais chances de considerarque o principal benefício da carne rastreada é oferecer mais segurança alimentar; enquanto os com maior renda apresentam3,23 mais chances de aceitar pagar mais pela certificação da carne. Ou seja, pessoas com maior escolaridade apresentarammelhor conhecimento sobre esse tipo de certificação, enquanto aqueles com maior renda mostraram maior aceitação em pagarmais caro pela carne bovina rastreada.

The aim of this study was to verify which socioeconomic factors are related to the decision to purchase meat with certification oforigin, as well as raising the profile of perception and attitude of consumers of meat in São Luís/MA. The description of the variableswere performed and constructed a multiple model Generalized Estimating Equations (GEE) of logistic regression model using thestatistical package SPSS 18.0, to identify possible associations between socio-demographic characteristics of the consumers andthe main attributes of the meat that influence the decision for its purchase raised through interviews among 400 respondents inMarch 2012. The seal of quality for acquisition of the meat was the attribute that most influences (32,5%) the purchasing decisionsof consumers. Most respondents (68,7%) never heard about bovine traceability. Amongst these who had heard about traceability,most (71,2%) would be willing to pay more for meat with certification of origin, although considering that there are disadvantagesassociated with traceability, especially in relation to the increase in the price of meat. Consumers with greater levels of schoolingpresent 2,62 more chances of having already heard of traced meat and 1,90 more chances of considering that the main benefitof traced meat is to offer more food security, while the ones with bigger income present 3,23 more chances of accepting to paymore for the certification of the meat. This means that people with greater schooling present better knowledge about this type ofcertification, while those with bigger income show bigger acceptance to spend more money on traced meat.

Seroprevalence for Neospora caninum in goats of Minas Gerais state, Brazil.

This study was aimed at determining the prevalence of anti-Neospora caninum antibodies in serum samples from 667 goats, collected from 90 herds in 90 municipalities in eight of the twelve mesoregions of Minas Gerais State. The presence of anti-N. caninum antibodies was determined by IFAT with a cut-off value of 1:50. The true herd-level seroprevalence in the entire study area was 75.2% (CI 95%: 59.5-90.9%). The true individual-level seroprevalence in the entire study area was 10.7% (CI 95%: 8.3-13.4%) with titers ranging from 50 (50.5%) to 3200 (1.7%). The serological evidence from this study indicated that N. caninum infection is widely distributed among goat-rearing herds in Minas Gerais and further studies are needed in order to evaluate the impact of this parasite as a cause of reproductive disorders.
