“…The most frequent serogroups in this study, Icterohaemorrhagiae and Ballum, have synanthropic rodents as their main reservoirs [ 3 , 34 , 35 ] and are of relevant importance in human leptospirosis [ 36 , 37 ]. Other serogroups found were Grippotyphosa, which is related to rodents or other wild animals [ 5 , 8 , 38 , 39 ]; Canicol, which has dogs as reservoirs [ 10 , 35 , 40 ]; and Semaranga, a saprophytic strain associated with cross−reactions involving many infectious serovars, often absent from the panel of serogroups used in the MAT [ 41 , 42 ].…”

Donkeys (Equus asinus) are historically known for their close relationship to humanity, which raises the need to study zoonotic diseases that affect them. In this perspective, leptospirosis stands out as a disease with an economic and public health impact, and its occurrence is facilitated in times of higher rainfall indexes, especially in large urban centers. In view of the scarcity of information about leptospirosis in donkeys, the objective of this study was to detect the presence of Leptospira spp. and anti-leptospiral antibodies in donkeys rescued by a zoonosis center located in the Caatiga biome, Brazilian semiarid region. Overall, 30 donkeys of both sexes, aged between 4 months and 15 years, were used, from which 64 serum samples were collected and submitted to the microscopic agglutination test (MAT). In addition, 64 samples of urine, vaginal and preputial fluid, in duplicates, were subjected to the polymerase chain reaction (PCR) and microbiological. Sixteen (53.3%) animals tested positive in at least one diagnostic test, 12 (40%) of which were positive at MAT and seven (23.3%) in the molecular and bacteriological detection (urine, vaginal, and preputial fluid samples). This is the first report identifying donkeys infected with Leptospira spp. by molecular and bacteriological diagnosis in Brazil, and the first in the world to detect this agent in their genital fluids. The study also shows that donkeys are commonly exposed to leptospires in the Caatinga biome, and this constitutes a One Health-based concern, demonstrating the importance of broad studies where large numbers of humans and animals coexist when investigating zoonotic infections and when planning and implementing control measures for donkeys-associated leptospirosis.

Leptospirosis is a zoonotic disease that causes financial and significant problems for herds. The objective was to define a prevalence of Leptospira spp. in serovar samples from 145 stray donkeys from the Brazilian semiarid region using the microscopic agglutination test (MAT), 24 serovars of Leptospira spp. Of the reactive animals, 34 of 145 (23%) had titers between 100 and 3,200. The serovars identified in the sera with high frequency were Kennewicki and Bratislava. In these animals serovars, Pyrogenes, Tarassovi, Canicola, Guaricura, Icterohaemorrhagiae, Grippotyphosa and Copenhageni were also used, showing animals with a lower rate of positive reactivity. This result indicates that the animals studied may be in contact with serovars Kennewicki and Bratislava, since wild animals, rodents and swine may harbor these serovars. Thus, the lack of adoption of protected sanitary measures may favor the occurrence of infection in the sampled animals, prevailing in the herd studied.
