Leptospirosis is an infectious and contagious bacterial disease that affects domestic and wild animals, in addition to being an important zoonosis. In dogs, it constitutes a serious public health problem, as they can be asymptomatic carriers, acting as reservoirs and, for this reason, animals present in Animal Protection Organizations can be reinserted in the community with intermittent elimination of the pathogen, which can cause contamination of other animals and man himself. The present study aimed to investigate the frequency of leptospirosis in dogs present in Animal Protection Organizations in the municipality of Caicó, state of Rio Grande do Norte, Brazil. The experiment was carried out from August to November 2017, when 35 blood samples were collected. The diagnosis of leptospirosis was determined by the Microscopic Soroagglutination Test (MAT) technique, using a collection of 24 serological variants. For the characterization of the most frequent serogroups, antibody titration was performed subsequently. The frequency found was 8.57% for the Pomona serogroup, the only one registered in the study and which has pigs as important reservoirs. It becomes necessary to avoid the contact of dogs with pigs and to implement the elaboration of disease control programs with actions directed to the use of vaccines for stray dogs and environmental sanitation, with the purpose of preventing the transmission of the disease to humans and others animals.
Leptospirosis is an infectious disease that affects both domestic and wild animals, in addition to being an important zoonosis. In sheep farming it is mainly responsible for causing problems in the reproductive sphere, such as abortion, birth of weak and premature offspring, in addition to a drop in production. The sheep species is not refractory to the disease, and infected sheep can remain in the herd as amplifiers of the infection. Based on the lack of studies on the presence of the bacteria in the animals of the region, the present study aimed to verify the presence of anti-Leptospira sp. in sheep in the microregion of São João do Rio do Peixe, Paraíba state, Brazil. Blood samples were collected from 50 animals, and the experiment was conducted between December 2017 and February 2018. The diagnosis of leptospirosis was determined by the microagglutination test (MAT) technique, using a collection of 24 serological variants. The frequency found was 2% of the animals, all reactions occurred for the serogroup Pomona, which is normally maintained by the swine species. This transmission probably occurred due to the contact between species. The results found demonstrate the need to implement preventive measures, such as, for example, avoiding contact with pigs and their excreta, serological monitoring of herds, cleaning and disinfection of facilities and the use of personal protective equipment, especially for people working in direct contact with this species.
selecionados para participar de entrevista semiestruturada. Resultados: 45,6% dos pais e cuidadores possuíam o ensino médio, 54% ganhavam até um salário mínimo e 42% tinham um filho. 70% possuíam termômetro, 48,4% não observaram o tempo adequado para retirálo. 29,4% verificavam pela palpação. 34,3% conceituaram febre a partir de 37,5°C. 96,3% administravam antitérmicos e 83,3% desconheciam os efeitos adversos. 14% administravam antibióticos. 70% consideravam que a febre trazia malefícios e que o pior dano é a convulsão.Os discursos sugeriram forte influência cultural e do saber comum. Conclusão: Considerase, portanto, que os participantes possuíam medos, crenças e práticas de manejo da febre similares. Em algumas situações demonstraram conhecimento e percepções limitados, ocasionando em atitudes errôneas frente à febre. A febre fobia persiste, pais ou cuidadores demonstram insegurança para cuidar da criança febril.
