ABSTRACT

Obstructive urolithiasis is a disease characterized by the presence of uroliths in the urinary tract, with consequent obstruction of excretion pathways. This paper described the epidemiological and clinical-pathological findings of 22 outbreaks of urolithiasis in growing-finishing pigs in Southern Brazil. All affected pigs were male and clinical presentation consisted of lethargy, dysuria, rectal prolapse, abdominal distention, peripheral cyanosis and reluctance to move. Clinical progression course ranged from 12 hours to one week, and the lethality rate was 100%. Gross changes were characterized by urinary bladder rupture associated with marked amount of yellowish liquid with ammoniacal odor (urine) in the abdominal cavity (uroperitoneum), as well as mild fibrin deposition on the surface of abdominal organs and hydronephrosis. Urinary uroliths ranging from 0.3 to 1cm in diameter were often observed obstructing the lumen of the penile urethra and sometimes those were free in the abdominal cavity. Histopathological findings included diffuse and marked urinary bladder edema and hemorrhage associated with inflammatory infiltrate of lymphocytes, plasma cells, and macrophages. Diffuse and marked necrosis of the mucosal epithelium was observed in the penile urethra. Intense fibrin deposition and inflammatory infiltrate of neutrophils were noted in the peritoneum, as well as in the serosa of the organs in the abdominal cavity. Uroliths were submitted to the method of qualitative determination of the mineral components, and were compatible with calcium carbonate and magnesium ammonium phosphate. Growing pigs ration analysis revealed low levels of calcium in relation to phosphorus, resulting in a Ca:P ratio of approximately 0.35:1. Histological findings and mineral analysis suggest that outbreaks of urolithiasis were related to a nutritional imbalance in the proportions of dietary calcium and phosphorus. The main cause of mortality was related to dehydration and uroperitoneum.(AU)


Urolitíase obstrutiva é uma enfermidade caracterizada pela presença de urólitos no trato urinário, com consequente obstrução das vias de excreção. Este artigo descreve os achados epidemiológicos e clínico-patológicos de 22 surtos de urolitíase em suínos de crescimento e terminação no Sul do Brasil. Os suínos afetados eram machos e clinicamente apresentavam letargia, disúria, prolapso retal, abaulamento do abdômen, extremidades cianóticas e relutância em movimentar-se. A duração dos sinais clínicos variou de 12 horas a uma semana, e a letalidade foi de 100%. As alterações macroscópicas caracterizaram-se por ruptura da bexiga com acentuada quantidade de líquido de coloração amarelada e odor amoniacal (urina) livre na cavidade abdominal (uroperitônio), além de discreta deposição de fibrina sobre os órgãos e hidronefrose. Frequentemente obstruindo o lúmen da uretra peniana e por vezes livre na cavidade abdominal, era possível observar urólitos urinários que variavam de 0,3 a 1cm de diâmetro. Os achados histopatológicos incluíram edema e hemorragia difusos e acentuados na bexiga, associado a infiltrado inflamatório predominante de linfócitos, plasmócitos e macrófagos. Na uretra peniana havia necrose difusa e acentuada do epitélio da mucosa. No peritônio e nas serosas dos órgãos da cavidade abdominal havia intensa deposição de fibrina e infiltrado neutrofílico. Os urólitos foram submetidos ao método de determinação qualitativa dos componentes minerais, os quais foram compatíveis com carbonato de cálcio e fosfato de amônio magnesiano. A análise da ração de crescimento revelou baixos níveis de cálcio, em relação ao fósforo, perfazendo uma relação Ca:P de aproximadamente 0,35:1. Os achados histológicos e as dosagens minerais sugerem que os surtos de urolitíase foram relacionados a um desequilíbrio nutricional nas proporções de cálcio e fósforo dietético. A principal causa da morte dos suínos foi relacionada à desidratação e ao uroperitônio.(AU)

ABSTRACT

O enriquecimento ambiental é uma ferramenta importante dentro dos sistemas de produção, a fim de promover o bem-estar e favorecer a saúde dos animais. Portanto, o objetivo deste trabalho foi avaliar o efeito do enriquecimento ambiental sobre o estresse de suínos na fase de creche. Foram utilizados 32 leitões, alojados em granja experimental, distribuídos em quatro grupos (n= 8): corda, corrente, garrafa PET e controle negativo. Amostras de sangue foram coletadas no início e no final do experimento para contagem de leucócitos circulantes e determinação de antioxidantes não enzimáticos, óxido nítrico, malondialdeído, e de saliva para avaliação do cortisol. Foi aplicado etograma e fez-a ganho médio de peso diário e a conversão alimentar. Os parâmetros avaliados no primeiro dia do experimento não variaram entre os grupos (P>0,05). No último dia do experimento, os valores de neutrófilos e da relação neutrófilo/linfócito foram mais elevados nos leitões do grupo corrente, assim como os valores de cortisol salivar (P<0,05). O ácido úrico apresentou-se mais elevado nos leitões do grupo corrente e o malondialdeído (MDA) nos do grupo garrafa (P< 0,05). Os enriquecimentos ambientais estimularam comportamentos positivos nos leitões, tendo a corda se destacado como o mais atrativo. Por outro lado, a corrente apresentou efeito negativo sobre a fisiologia dos animais, gerando estresse, assim como a garrafa, que induziu a peroxidação lipídica e um menor ganho de peso nos leitões.(AU)


Environmental enrichment is an important tool within production systems to promote welfare and animal health. The aim of this study was to evaluate the effect of enrichment objects on stress of piglets in nursery phase. 32 piglets housed in experimental farm were distributed in 4 groups (n= 8): rope, chain, pet bottle and negative control. Blood samples were collected at the beginning and end of the experiment to count circulating leukocytes and determine non-enzymatic antioxidants, nitric oxide, malondialdehyde, and saliva to evaluate cortisol. At the same time, an etogram and evaluation of mean daily gain and feed conversion were applied. The evaluated parameters on first day of the experiment did not vary between groups (P> 0.05). On the last day, neutrophil and neutrophil /lymphocyte ratios were higher in chain group piglets, as were salivary cortisol values (P< 0.05). Uric acid was higher in chain group and MDA in bottle group (P< 0.05). Environmental enrichment stimulated positive behaviors in piglets, where the rope stood out as the most attractive. On the other hand, chain had a negative effect on animal physiology, generating stress, as well as the bottle that induced lipid peroxidation and a lower weight gain in piglets.(AU)

ABSTRACT

Com o objetivo de avaliar a situação epidemiológica da cisticercose suína e bovina na zona rural de cinco municípios, distribuídos em três distintas regiões do estado de Minas Gerais, foi determinada a prevalência das cisticercoses bovina e suína nas propriedades rurais e os principais fatores de risco que poderiam favorecer a transmissão e manutenção da doença nas referidas propriedades. A pesquisa abrangeu 388 propriedades, localizadas em 91 diferentes comunidades rurais, sendo coletadas 1.792 amostras de sangue bovino e 554 de suíno. Além da avaliação das referidas amostras laboratoriais (ELISA indireto e imunoblot), também foram analisados os dados obtidos da aplicação de um questionário para cada propriedade, no qual constava as informações sobre as condições socioeconômicas, higiênico-sanitárias e as relacionadas ao sistema de criação animal. A prevalência da cisticercose variou de 0,3 a 5,9% nos bovinos e de 0 a 2,8% nos suínos criados artesanalmente nesses municípios pesquisados. Os principais fatores de risco de transmissão identificados foram a fonte de água consumida, a origem da carne, a natureza do município e da região, para a cisticercose bovina, e o destino do esgoto e o sistema de criação, para a cisticercose suína.(AU)


In order to evaluate the epidemiological situation of porcine and bovine cysticercosis in the rural area of five municipalities, distributed in three different regions of the state of Minas Gerais, Brazil, the prevalence of bovine and porcine cysticercosis was determined in the rural properties as well as the main risk factors that may favor the transmission and maintenance of the disease in these properties. The research covered 388 farms, located in 91 different rural communities, with 1,792 samples of bovine blood and 554 of swine collected. In addition to the evaluation of these laboratory samples (indirect ELISA and Imunoblot), the data obtained from the application of a questionnaire for each property were also analyzed, with information on socioeconomic, hygienic-sanitary and animal-related conditions. The prevalence of cysticercosis ranged from 0.3 to 5.9% in cattle and from 0 to 2.8% in the pigs raised in these municipalities. Among the main risk factors for transmission of bovine cysticercosis were the source of water consumed, the origin of the meat, the nature of the municipality and the region. Regarding the pigs, risk factors were the sewage disposal and animal management system.(AU)

ABSTRACT

The primary objective of the current study was to compare the pharmacokinetic (PK) of florfenicol (FFL) in pulmonary epithelial lining fluid and the plasma in swine. The second objectives were to evaluate the effect of anesthesia with ketamine and propofol on the PK of FFL in plasma. Bronchoaveolar lavage was utilized for quantification of PELF volume and the urea dilution method was used to determine the concentration of FFL in PELF. FFL was administered intramuscularly (IM) to swine in a single dose of 20mg/kg body weight. The main PK parameters of FFL in plasma and PELF were as follows: the area under the concentration-time curve, maximal drug concentration, elimination half-life and mean residence time were 69.45±4.36 vs 85.03±9.26µg·hr/ml, 4.65±0.34 vs 5.94±0.86µg/ml, 9.87±1.70 vs 10.69±1.60hr and 12.75±0.35 vs 14.46±1.26hr, respectively. There was no statistically significant difference between the PK profiles of FFL for the anesthetized and unanesthetized pigs. This study suggest that (i) FFL penetrated rapidly into the pulmonary and the drug concentration decay faster in plasma than in the pulmonary, (ii) the PK profile of FFL in swine was not interfered after administration of anesthetic agent.(AU)


O objetivo primário desse estudo foi comparar a farmacocinética de florfenicol (FFL) em fluido epitelial pulmonar à farmacocinética (PK) de FFL em plasma suíno. O segundo objetivo foi avaliar o efeito de anestesia com ketamina e propofol no PK de FFL em plasma. Lavagem broncoalveolar foi utilizada para quantificar volume de fluido epitelial pulmonar (PELF) e método de diluição de uréia para determinar FFL em PELF. Injeção de FFL foi administrada intramuscular a suínos em dose única de 20mg/kg de peso corporal. Os principais parâmetros de PK em FFL em plasma e PELF foram os seguintes: a área sob a curva de concentração-tempo, concentração máxima da droga, eliminação de meia-vida e média de tempo de permanência foram 69,45±4,36 vs 85,03±9,26µg·hr/ml, 4,65±0,34 vs 5,94±0,86µg/ml, 9,87±1,70 vs 10,69±1,60hr e 12,75±0,35 vs 14,46±1,26hr, respectivamente. Não houve diferença estatisticamente significante entre os perfis de PK de FFL para os porcos anestesiados e não anestesiados. Esse estudo sugere que (i) FFL penetrou rapidamente no pulmão e concentração da droga sofre queda mais veloz em plasma que líquido pulmonar, (ii) o perfil de PK de FFL em suínos não modificou após administração de agente anestésico.(AU)

ABSTRACT

Two outbreaks of poisoning by selenium in swine in southern Brazil are described. Piglets were affected in the post-weaning period, between 27 and 22 days, with mortality rates ranging from 16% to 15.3% (Outbreak 1 and 2 respectively). The pigs had focal symmetrical poliomielomalacia and hoof lesions, which were initially characterized by a reddish line at the coronary band that evolved in surviving pigs to release of the hooves. Clinical signs were observed after six days (Outbreak 1) and 30h (Outbreak 2) after the introduction of feed with high selenium content...


São descritos dois surtos de intoxicação por selênio em suínos na região Sul do Brasil. Foram acometidos leitões em fase de creche, entre 27 e 22 dias, com mortalidade variando de 16% a 15,3% (Surto 1 e 2 respectivamente). Os suínos apresentaram poliomielomalacia simétrica focal e lesões de casco, que inicialmente eram caracterizadas por uma linha avermelhada na borda coronária que evoluía nos suínos sobreviventes para desprendimento do casco. Os sinais clínicos iniciaram após seis dias (Surto 1) e 30 horas (Surto 2) da introdução da ração com alto teor de selênio...

ABSTRACT

A Salmonella pode estar presente em carcaças suínas ao final da tecnologia de abate, sendo que não existem procedimentos de inspeção especificamente direcionados para o controle desta bactéria, consideradas um risco potencial para a saúde pública. O objetivo do trabalho foi verificar a presença de Salmonella em carcaças suínas e caracterizar os pontos críticos de controle (PCCs) da tecnologia de abate como subsídio ao sistema APPCC. Foram realizados swabs de carcaças após a escaldagem/depilação, antes da evisceração, após evisceração e serragem da carcaça e após 24 horas de refrigeração, gerando 120 amostras (30 carcaças de cinco lotes). Isolou-se Salmonella em 53,3% dos PCs analisados, sendo 40% antes da eviscerarão e 30% após a escaldagem/depilação e evisceração/serragem. Nas carcaças resfriadas por 24 horas não foi isolada Salmonella. Os sorovares identificados foram Typhimurium (96,7 %) e Panama (3,22%). O isolamento de Salmonella reforça a necessidade de programas de monitoria da bactéria, desde as granjas até os abatedouros, enquanto o não isolamento nas carcaças resfriadas indica a importância da lavagem final e adequação da cadeia do frio, o que minimiza a contaminação pela intensificação das medidas de higiene e controle de pontos críticos para subsidiar o sistema APPCC...


Salmonella can be present in swine carcasses at the end of slaughtering and there is no specifically guided inspection procedure for the control of this bacterium, considered a potential risk for public health. The objective of this paper is to verify the presence of Salmonella in carcasses and to characterize the critical points of control (CPCs) of the slaughtering technology as a subsidy to the HACCP system. The carcasses were swabbed at different points during the slaughtering process, ant after 24 hours of refrigeration, generating 120 samples (30 carcasses from five different batches). Salmonella was isolated in 53.3% of the CPs analyzed, being 40% before evisceration and 30% after scalding/depilation and evisceration/ sawing. No Salmonella was isolated in the carcasses refrigerated for 24 hours. Typhimurium (96.7%) and Panama (3.22%) were the serovars identified. Salmonella isolation indicates the need of programs to monitor the bacterium from the farms to the slaughterhouse, while the non-isolation in the refrigerated carcasses shows the relevance of the cold chain, which minimizes the contamination by the intensification of hygiene measures and the control of critical points to subsidize the HACCP system...

ABSTRACT

This study reports on changes in the number of somatostatin-like immunoreactive (SOM-LI) endocrine cells in the porcine descending colon, caused by chemically driven inflammation, axotomy and proliferative enteropathy (PE). The distribution pattern of SOM-LI endocrine cells has been studied using the routine single-labelling immunofluorescence technique. Semi-quantitative evaluation of the number of the SOM-immunostained endocrine cells within the mucosal layer of the porcine descending colon has been based on counting of all endocrine cells immunoreactive to SOM per unit area (0,1 mm²). Under physiological conditions the number of SOM-LI endocrine cells has been shown to constitute 3,30±0,22. All applied pathological processes resulted in changes in the SOM-like immunoreactivity, which varied in particular processes studied. The number of SOM-LI endocrine cells increased to 6,28±0,31 and 4,43±0,35 during chemically driven inflammation and proliferative enteropathy, respectively, and decreased to 1,17%±0,16 after axotomy. The obtained results suggest that SOM-LI endocrine cells may participate in various pathological states within porcine descending colon and their functions probably depend on the type of pathological factor.(AU)

ABSTRACT

O objetivo deste trabalho foi avaliar e classificar as principais causas de morte de leitões com até seis dias de idade, em umsistema intensivo de suínos confinados (SISCO), localizado na região médio-norte do estado de Mato Grosso durante o anode 2006. Observaram-se 48.416 leitões provenientes de 2.054 matrizes. Verificou-se taxa de mortalidade de 7,43% do totalde nascidos vivos. As causas mais frequentes de mortalidade, em relação ao total de nascidos vivos, foram esmagamento(24,14%), debilitação (8,01%), síndrome diarreica (6,0%), defeitos genéticos (2,41%) e outras causas sem diagnósticoconfirmado durante a necrópsia (15,20%). A taxa de natimortalidade em relação ao total de nascidos foi de 5,59%. Comrelação à sazonalidade das mortes, observou-se maior índice de mortalidade por síndrome diarreica durante a primavera,que coincide com os meses mais quentes do ano, não observando tendência para morte por esmagamento em nenhumaépoca do ano.


The objective of this research was to evaluate and to classify (by means of postmortem findings), the occurrence of the preweaning losses of piglets until the six days of age, in a intensive system of bordered pigs, at the middle north of Mato Grosso State during the year 2006. They had been observed a total of 48.416 piglets proceeding from 2.054 wombs. Was verified the tax of mortality of 7,43% of that livings piglets had been born. The most frequent causes of losses were overlaying (24.14 %), diverse causes (15.20), weakness (8.01 %), diarrhea syndrome (6.0 %) and genetic defects (2.41 %). Stillbirth rate, in relation to total born, was 5.59 %. In relation of periodicity deaths, it was observed a higher number of diarrhea syndrome during the spring, that coincides with the hottest months of the year, wasn’t observed trends of overlaying deaths none time during the year.

ABSTRACT

Hay muchas enfermedades con hemorragias difusas que ocurren en cerdos alrededor del mundo. Estas pueden ser de origen viral como el Cólera Porcino (C P) conocido como Fiebre Porcina Clásica ( F P C) o Peste Porcina Clásica (P P C), producido por un Pestivirus (ARN) del grupo Togavirus, de la familia Flaviviridae; o también la Peste Porcina Africana (P P A) producida por un Iridovirus y la cual de acuerdo a la literatura no ha sido diagnosticada en Venezuela. Entre las de origen bacteriano están la Salmonelosis y Erisipelosis porcina, siendo ésta última poco frecuente en Venezuela. Los cambios hemorrágicos observados en los cerdos bajo estudio son muy similares a aquellos que ocurren en la F P C caracterizada ésta, por afectar varios órganos vitales e induciendo una alta tasa de mortalidad. La F C P cursa en forma aguda con hemorragias generalizadas, alta morbilidad y mortalidad o en forma crónica con signos clínicos y lesiones mínimas o ausentes. El agente etiológico de F P C tiene un efecto letal en animales infectados de forma natural y en animales postvacunados induce lesiones letales, que aunque más suaves producen una alta mortalidad, debido a factores de la vacuna o al estatus inmunológico del cerdo...


Many diseases occur in pigs causing widespread hemorrhages around the world. Among them are viral or bacterial such as, Classical Swine Fever (C S F) which is produced by a Pestivirus (RNA), Togavirus group of the Flaviviridae family, besides African Swine Fever (ASF) produced by an Iridovirus and which has not been diagnosed in Venezuela, according to the literature. Among bacterial diseases are Salmonellosis and Erysipellosis, being the latter uncommon in Venezuela. In this paper, the morphological aspects of a hemorrhagic disease in four pigs are described. The reported lesions are not too dissimilar to those occurring in cases of C S F, which is characterized by affecting many vital organs, producing death in many pigs. C S F often follows an acute course characterized by generalized hemorrhages, with high morbidity and mortality, but it may be chronic, in that case clinical signs and lesions are often minimal or absent. The disease in naturally infected pigs produces lethal lesions causing death in many unvaccinated animals as well as in vaccinated pigs. The gross and microscopic changes of a hemorrhagic systemic disease in four (4) cases under study are reported from two naturally infected unvaccinated pigs and two postvaccinated animals against C S F. Pathologic changes are correlated with clinical signs and the most relevant morphological gross changes and histopathology are reported from naturally infected unvaccinated and postvaccinated pigs. The hemorrhagic lesions reported in vital organs highly resemble and are very similar to those morphologic changes occurring in C S F, although, other hemorrhagic viral or bacterial diseases induced a more severe and different pattern in lesions though being hemorrhagic. Despite lab tests (Elisa) were not determined in this work, they must be ruled out to show the etiological agent of C S F in spite of the typical and very similar morphological changes reported in this paper.

ABSTRACT

Inbred strains of pig become indispensable for a wide range of biological studies. In biomedical science, it is generally accepted that somatic cell nuclear transfer(SCNT)technology with inbreed strain of pig is essential for xenotransplantation. In this study, we observed the anal atresia in a cloned pig which was derived from fetal fibroblast of inbreed miniature pig. A presumptive anal site of the cloned pig was excised and the rectum was sutured to apposed skin for treatment. This cloned piglet seemed to be normal with healthy status after surgery. This report can be useful for the treatment of anal atresia of cloned piglets.
