ABSTRACT

Objetivo: analisar as características e a tendência temporal das taxas de mortalidade na população de 5 a 14 anos em Mato Grosso e no Brasil, no período de 2009 a 2020. Métodos: estudo ecológico de série temporal, sobre dados do Sistema de Informação sobre Mortalidade. As análises foram descritivas e de tendência, utilizando-se o modelo de regressão por pontos de inflexão (joinpoint) com cálculo da variação média no período (VMP). Resultados: no Brasil e em Mato Grosso, os óbitos foram predominantemente masculinos, evitáveis e por causas externas. Foi identificada tendência decrescente no Brasil (5 a 9 anos VMP: -2,9; IC95% -4,3;-1,6 e 10 a 14 anos VMP: -2,5; IC95% -3,3;-1,8) e estacionária em Mato Grosso (5 a 9 anos VMP: -2,0; IC95% -5,6;1,7 e 10 a 14 anos VMP: -0,1; IC95% -5,9;6,1). Conclusão: a tendência estável da mortalidade em patamares elevados demanda intervenções urgentes, visando a sua redução.

Objective: to analyze the characteristics and temporal trend of mortality rates in the population aged 5 to 14 years in Mato Grosso state and in Brazil, from 2009 to 2020. Methods: this was an ecological time-series study, based on data taken from the Mortality Information System. Descriptive and trend analyses were performed, using the joinpoint regression model and calculating the average annual percentage change (AAPC). Results: in Brazil and in Mato Grosso state, deaths were predominantly male, preventable and due to external causes. A falling trend was identified for Brazil (5-9 years AAPC: -2.9; 95%CI -4.3;-1.6 and 10-14 years AAPC: -2.5; 95%CI -3.3;-1.8), while a stationary trend was found in Mato Grosso (5-9 years AAPC: -2.0; 95%CI -5.6;1.7 and 10-14 years AAPC: -0.1; 95%CI -5.9;6.1). Conclusion: the stable trend of mortality at high levels demands urgent interventions to reduce it.

ABSTRACT

Abstract Feline Bartonella can be transmitted to humans through cat scratches or bites, and between cats, by the flea Ctenocephalides felis. The study was carried out in order to investigate the occurrence of Bartonella DNA in cats living in shelters and their ectoparasites and the relationship between the infection status of cats and ectoparasites they host. Bartonella DNA was detected in 47.8% of the cat blood samples, 18.3% of C. felis fleas, 13.3% of flea egg pools and 12.5% of lice pools. B. henselae and B. clarridgeiae DNA were detected in cat fleas, while B. henselae, B. clarridgeiae and B. koehlerae were found in blood samples from bacteremic cats. Cats infested by positive ectoparasites showed approximately twice the odds of being infected. Our results indicate that shelter cats have high prevalence of Bartonella species that are known to be human pathogens. This highlights the importance of controlling infestations by ectoparasites to avoid cat and human infection.


Resumo Algumas espécies de Bartonella têm os felinos como principais hospedeiros reservatórios. Tais patógenos são transmitidos ao homem por intermédio da arranhadura ou mordedura de gatos e entre os gatos, por meio da pulga Ctenocephalides felis. O objetivo deste estudo foi investigar a ocorrência de DNA de Bartonella spp. em gatos de abrigos e seus ectoparasitas e a relação entre o estado de infecção dos gatos e dos ectoparasitas albergados por estes. Material genético bacteriano foi detectado em 47,8% das amostras de sangue de gatos, 18,3% das pulgas C. felis, 13,3% dos "pools" de ovos de pulgas e 12,5% dos "pools" de piolhos. DNA de B. henselae e B. clarridgeiae foi detectado em pulgas, e B. henselae, B. clarridgeiae e B. koehlerae, em amostras de sangue de gatos. Gatos infestados por ectoparasitas que carreavam DNA de Bartonella spp. demonstraram aproximadamente o dobro de chance de estarem infectados. Esses resultados indicam que os gatos de abrigos têm alta prevalência de infecção por espécies de Bartonella, capazes de causar doenças no homem. E também destacam a importância do controle e prevenção da infestação por ectoparasitas, no intuito de prevenir a infecção em gatos e humanos.

ABSTRACT

ABSTRACT This study verified the occurrence of Bartonella spp. in dogs, cats, wild mammals and their ectoparasites in Petrolina and Lagoa Grande Counties, Pernambuco, located in a semi-arid region in Northeastern Brazil. Anti-Bartonella spp. antibodies were detected by indirect immunofluorescence assay (IFA) in 24.8% of dogs (27/109) and in 15% of cats (6/40). Bartonella sp. DNA was identified by PCR performed on DNA extracted from blood and ectoparasites using primers targeting Bartonella sp. gltA and ribC genes in 100% (9/9) of Pulex irritans from Cerdocyon thous, 57.4% (35/61) of P. irritans from dogs, 2.3% (1/43) of Ctenocephalides felis felis from dogs, 53.3% (24/45) of C. felis felis from cats, and 10% (1/10) of Polyplax spp. from Thrichomys apereoides. DNA sequencing identified Bartonella clarridgeiae and Bartonella henselae in C. felis felis from cats, Bartonella rochalimae in P. irritans from dog and C. thous, and Bartonella vinsoni berkhofii in P. irritans from dog.

ABSTRACT

Brazilian spotted fever (BSF) is the most important and frequent rickettsial disease in Brazil. A fatal case of BSF is reported in a 32-year-old black man, who died of irreversible shock after five days of fever, severe headache and abdominal pain with no rash. Spleen, kidney and heart samples collected at autopsy were positive for Rickettsia rickettsii by PCR and sequencing. The authors emphasize the need for a high index of diagnostic suspicion for spotted fever in black patients. Absence of a skin rash should not dissuade clinicians from considering the possibility of BSF and initiating empirical therapy.


Febre maculosa brasileira (FMB) é a mais importante e frequente doença rickettsial no Brasil. Relatamos um caso fatal de FMB em um homem negro de 32 anos de idade que morreu de choque irreversível após cinco dias de febre, cefaléia intensa, dor abdominal, e sem evidência de exantema. Amostras de baço, rim e coração coletadas na necropsia foram positivas para Rickettsia rickettsii por PCR e sequenciamento. Os autores ressaltam a necessidade de um alto índice de suspeita diagnóstica para febre maculosa em pacientes negros. Ausência de exantema não deve dissuadir os clínicos de considerar a possibilidade de FMB e iniciar a terapêutica empírica.

ABSTRACT

Bartonella henselae e mais recentemente B. quintana têm sido apontados como agentes causais de diversas moléstias emhumanos, entre as quais a doença da arranhadura do gato, endocardite, meningoencefalite e neuroretinite, podendo levarao óbito, principalmente os imunocomprometidos. O gato doméstico é considerado o principal animal envolvido na transmissãodestes patógenos. Constituiu-se objetivo deste estudo a avaliação da frequência de Bartonella spp. em gatos domésticosdomiciliados do município de Vassouras (RJ) comparando-se os achados na reação em cadeia pela polimerase (PCR) e nasorologia por imunofluorescência indireta (IFA). Amostras sanguíneas de 37 (100%) gatos de um abrigo da cidade deVassouras (RJ) foram analisadas, sendo 36 (97,3%) positivas na PCR para Bartonella spp. Das amostras PCR positivas,nove (25%) e 27 (75%) apresentaram, respectivamente, reatividade e ausência de reatividade ao IFA. Apenas uma (2,7%)amostra de sangue foi concomitantemente negativa na PCR e IFA para Bartonella spp. Este é o primeiro registro de infecçãopor Bartonella spp. em felinos domésticos no estado do Rio de Janeiro (Brasil) identificada por análise molecular e sorológica,o que nos permite concluir que este agente zoonótico está presente em alta frequência em gatos domésticos do municípiode Vassouras (RJ).


Bartonella henselae and B. quintana have been pointed as causal agents of many diseases in humans, and can lead to death, mainly immunodefficient people. Domestic cat is considered the unique animal in transmission of these pathogens. The purpose of this study was to evaluate the frequency of Bartonella spp. in domestic cats from Vassouras city (RJ) by polimerase chain reaction (PCR) and indirect immunofluorescence test assay (IFA) and compare the results. Blood samples from 37 (100%) domestic cats from a shelter of Vassouras city (RJ) were analyzed and 36 (97.3%) were considered positive by polymerase chain reaction (PCR). The indirect immunofluorescence test assay (IFA) revealed 9 (25.0%) and 27 (75.0%) of that PCR positive samples showed, respectively, reaction and absence of reaction to IFA. Only one sample (2.7%) was negative in PCR and IFA. This is the first communication of Bartonella spp. infection in domestic cats in Rio de Janeiro State (Brazil) identified by molecular and serological assays, thus it can be concluded that this zoonotic agent is present in high frequencies in domestic cats from Vassouras city (RJ).

ABSTRACT

Cat scratch disease (CSD) is a self limited condition characterized by fever, lymph node enlargement and less often eye involvement. Central nervous system involvement by Bartonella henselae infection is possibly an important cause of morbidity; its role as an agent of aseptic meningitis is unknown. We report a case of a 40 years-old man with CSD accompanied by aseptic meningitis and neuroretinitis. Serum indirect immmunofluorescence (IFI) assays for B. henselae were positive and the cerebrospinal fluid (CSF) analysis showed mononuclear pleocytosis and increased level of protein. Serological tests for other etiologies were negative. The patient responded well to antibiotic therapy with oral doxycicline plus rifampin and in the 12th day of hospitalization evolved to total regression of the headache and partial regression of the visual loss. Clinicians should consider CSD as a differential diagnosis when assessing previously healthy patients with aseptic meningitis associated with regional lymphadenopathy and epidemiological history of feline contact.
