Serological survey of leptospirosis in livestock animals in the Lesser Antilles.
A serological survey was performed of 1788 cattle, goats and sheep on 13 islands in the Lesser Antilles. Sera were tested by microscopic agglutination (MAT) using a panel of 22 live antigens. Evidence of past exposure, at a titer of > or = 100, was found in 101 animals (5.6%). Antibodies were more common in cattle and goats (7.2% in each) than in sheep (1.7%). Seroprevalence was highest in cattle in Martinique (20%) and in goats in St. Vincent (23%). The predominant serogroups were Sejroe (largely confined to cattle in Martinique), Autumnalis, Icterohaemorrhagiae, Grippotyphosa, and Cynopteri. Eleven cattle from Martinique and 2 sheep with titers of > or = 800 showed evidence of recent infection.
