Levantamento dos sorovares de leptospirose mais presentes em exames sorológicos de caninos e bovinos no Maranhão

Abstract

Leptospirosis is a zoonosis with worldwide distribution and great economic and social importance. It is caused by a bacterium of the genus Leptospira, which can be transmitted both through rodent urine and water contaminated by the bacteria, affecting domestic animals, humans, and wild animals. It is endemic in Brazil, with higher occurrence in urban areas that have poor sanitation, and higher numbers of cases in countries with tropical climates, especially during rainy seasons. The objective of this work is to evaluate the most frequent serovars in serological tests of cattle and dogs in the state of Maranhão from 2015 to 2019 and thus identify them. In the case of this work, a survey was conducted with all the data collected from the laboratory of infectious diseases at UEMA, focusing on the fact that 514 samples were analyzed, being 426 from canines and 88 from cattle with a very high number of positives and always observing the place with more cases, the species and the type of serovar that reacted. Finally, we can note which serovars appeared more frequently, in which years there were more cases and which location had high rates
