D. de  aLeptospirosis seroprevalence and associated risk factors in dairy goats in the Brazilian semi-arid region.h[electronic resource]  c2024  aAbstract: Leptospira spp. infection is a worldwide zoonosis that causes economic losses to goat rearing, mainly due to reproductive disorders. Hence, the objective of this research was to determine the seroprevalence and associated risk factors of leptospirosis in a goat milk-producing region in the states of Paraiba and Pernambuco, Northeast Brazil. The microscopic agglutination test was used as serological method and risk factor analysis was carried out using univariable and multivariable analyses. Out of the 937 animals sampled, 102 (10.9 %; 95 % CI = 8.9–12.9 %) were seropositive for Leptospira spp. and the most frequent serogroups were Ballum (41.2 %; 95 % CI = 31.6–50.7 %), Icterohaemorrhagiae (25.5 %, 95 % CI = 17–33.9 %) and Semaranga (23.5 %, 95 % CI = 15.3–31.8 %), with antibody titres ranging from 1:50 to 1:200. Thirty-four of 51 herds (66.7 %; 95 % CI = 53.7–79.6 %) had at least one seropositive animal. The risk factor identified in the multivariable two-level random effect binary logistic regression was the animal being an adult (odds ratio = 4.2; 95 % CI = 1.93–9.13; P &lt 0.001). Our results provide important information on the epidemiology and risk factors associated with goat leptospirosis seroprevalence in one of the main Brazilian goat milk-producing regions. Furthermore, the need for adopting sanitary control measures, especially those involving sanitary management practices, is highlighted.  aBacterial infections  aBrazil  aDisease incidence  aDisease prevalence  aEpidemiology  aGoat diseases  aGoats  aLeptospira  aReproductive disorders  aRisk factors  aSemiarid zones  aSeroprevalence  aGoat herd1 aMORAIS, D. de A.1 aLIMA, A.
