Didelphis albiventris as a carrier of Leptospira sp. in the central nervous tissue in the semiarid region of Northeast, Brazil.

Leptospirosis has been investigated in several species of wild animals. The white-eared opossum (Didelphis albiventris) is a mammal common in the brazilian semi-arid, so, this study aimed to investigate its role in the occurrence of the leptospirosis in the region Northeast of Brazil. 12 animals were used, from which samples were collected for the attempt of isolation, molecular detection and serological examination.

High frequency of seropositive and carriers of Leptospira spp. in pigs in the semiarid region of northeastern Brazil.

Carrier animals are considered key in the transmission cycle of leptospirosis. Although investigations have been carried out on several species, the role of pigs in the epidemiology of the disease is still poorly studied in the semi-arid region. Thus, the objective of this study was to determine the presence of Leptospira spp.
