Os ataques de cães a seres humanos figuram como importante problema de saúde pública, devido ao risco da ocorrência de zoonoses, infecções secundárias, à necessidade de vacinação anti-rábica, e ao possível desenvolvimento de estresse pós-traumático nas vítimas. Com o objetivo de entender a dinâmica dos ataques ocorridos no município de Vassouras – RJ, no período de 2010 a 2017, o presente estudo baseou-se na resposta de questionários às vítimas dos ataques aplicados nos bairros distintos Ipiranga e Grecco, que identificam o perfil da vítima e do agressor, possível desenvolvimento de sequelas psicológicas no que diz respeito ao medo de cães. Entre 322 questionários aplicados, foram encontrados 93 casos de ataques caninos, demonstrando grande ocorrência de ataques no município, com possível potencial zoonótico, casos de subnotificação e gastos com tratamento das lesões ocorridas, destacando a prevalência dos ataques em ambos os bairros.
Visceral leishmaniasis, caused by the protozoan Leishmania chagasi, is a re-emergent anthropozoonosis and has become a major public health problem. In urban areas, dogs (Canis familiaris) are the main source of infection to humans. The canine enzootic disease precedes and is more prevalent that the human disease. The present study reports an autochthonous case of visceral canine leishmaniasis in Barra do Piraí, Rio de Janeiro. After detecting clinical signs consistent with canine visceral leishmaniasis, several diagnostic tests were performed, such as cytological examination of the ear tip and lymph node puncture, rapid immunochromatographic test, dual path platform, enzymatic immunoadsorption assay, indirect immunofluorescence assay, and culture of material obtained from skin biopsy and lymph node and bone marrow punctures. After clinical, serological, and parasitological confirmation of Leishmania, the dog's owner chose to euthanize it and, 3 months later, another positive animal residing in the same place was also euthanized. Based on this report, it is necessary to conduct entomological and epidemiological surveillances in Barra do Piraí to detect the presence of the vector and/or canine enzootic disease before initiation of the anthropozoonotic cycle, allowing actions to control the disease in canines and prevent its occurrence in humans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
