Apparently high Leptospira antibody seropositivity in donkeys for slaughter in three municipalities in Durango, Mexico:

We determined the seropositive percentage and the determinants of Leptospira exposure in domestic donkeys presented for slaughter in the State of Durango, Mexico. We examined 194 donkeys in 4 gathering premises. Sera of donkeys were analyzed for anti-Leptospira IgG antibodies using a microscopic agglutination assay with a panel of 7 Leptospira antigens. The association between Leptospira seropositivity and general characteristics of donkeys was assessed by bivariate and multivariate analyses. Antibodies against Leptospira (for at least 1 of the 7 Leptospira serovars examined) were found in 151 of 194 (77.8%) donkeys. Seropositive donkeys were found in all regions, municipalities, and premises examined. The predominant serovar was L. interrogans Icterohaemorrhagiae (n = 117; 60.3%), followed by L. interrogans Sejroe (n = 96; 49.5%), L. interrogans Canicola (n = 10; 5.2%), L. kirschneri Grippotyphosa (n = 6; 3.1%), L. borgpetersenii Ballum (n = 5; 2.6 %), L. biflexa Semaranga (n = 3; 1.5%), and L. noguchii ...
