F. da  aLeptospirosis in dairy cattle from Southern Brazilbrisk factors.h[electronic resource]  c2022  aCattle are susceptible to chronic leptospirosis infection, that results in reduced milk production and reproductive disorders such as abortions, stillbirths, fetal malformation, and mummified fetuses, causing significant economic losses. Commercially available vaccines against leptospirosis offer limited protection to cattle because they contain only the most prevalent serovars worldwide, even though they are not prevalent in the specific region. This study aimed to evaluate the prevalence of specific antibodies against Leptospira serogroups, reproductive disorders and the risk factors in dairy herds from different mesoregions of Rio Grande do Sul State, Southern Brazil.  aAnimal diseases  aDistúrbio Animal  aDoença Animal  aGado  aGado Leiteiro  aLeptospirose  aZoonose  aDistúrbio reprodutivo1 aALBA, D.
