Abstract

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 Panama ( n = 2; 1%). Leptospira seropositivity was associated with gathering premises (OR = 2.64; 95% CI: 1.27-5.46; p = 0.009) and municipalities (OR = 0.11; 95% CI: 0.01-0.78; p = 0.02). Our results demonstrate an appa...Continue Reading

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
