Special Issue Information

Dear Colleagues,

Leptospirosis is a disease that causes damage to animal and human health and is related to the environmental conditions where the maintenance and accidental hosts live. In production animals, it is one of the main diseases of reproduction and is associated with embryonic resorption, repeated estrus, abortions, stillbirths or weak animals. Sometimes it can occur in the form of outbreaks, with more than 75% of abortions in the batch, which causes great losses to the producer. The knowledge of molecular diversity, pathogenesis, dynamics of infection, epidemiology, diagnosis, serovars and serogroups that infect production animals, their immune response to infection and vaccination, as well as treatment, prevention, sanitary and environmental management are essential for the control of this disease in herds. This Special Issue addresses the need to strengthen the flow and exchange of information within this field through the publication of a selection of research articles from leading researchers. It is hoped that this Special Issue will further stimulate collaboration between scientists engaged in all aspects of this field of research.

Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Leptospirosis, caused by Leptospira, is a zoonotic disease that, in horses, is linked to abortions, uveitis, and sporadic occurrences of liver and kidney disease, often resulting in significant economic losses for farmers. Research on the prevalence of leptospirosis in horses in the central-west region of Brazil has been relatively scarce. Thus, the present study aimed to determine the prevalence of leptospirosis in equine herds in the state of Goiás (Central Brazil). Blood samples were collected from 894 equids at 294 randomly selected farms divided into three different strata according to their herd characteristics. The microscopic agglutination test for the detection of anti-Leptospira agglutinins was carried out and the results showed that among the 294 sampled farms, 213 (72.9%; CI 95% 71.7–78.9) had one or more animals positive for leptospirosis, and of the 894 horses sampled, 513 (61.6%; CI 95% 54.3–69.0) were seropositive for leptospirosis. Djasiman, Icterohaemorrhagiae, and Australis were the most prevalent serogroups. The results showed a high prevalence of seropositive animals and a widespread distribution of positive farms in the state of Goiás. Thus, environmental sanitation measures and health education to prevent and control equine leptospirosis in the state are required. Full article
