Leptospirosis is a zoonotic disease of global importance. Very little information is available on Leptospira infection in nonhuman primates. We report herein a high seroprevalence (49.4%; 95% confidence interval: 41.6-57.2%) to Leptospira serovars in vervet monkeys ( Chlorocebus sabeus) on the Caribbean island of Saint Kitts. Monkeys bred in captivity ( n = 81) had a significantly higher seroprevalence compared to wild-caught monkeys ( n = 81; p < 0.05). Seroprevalence to serovar Bataviae was significantly higher in monkeys bred in captivity and was higher to serovar Bratislava in wild-caught monkeys ( p < 0.05). Our data confirm that exposure to various Leptospira serovars and seroconversion occurs in wild and captive vervet monkeys on the Caribbean island of Saint Kitts. Further studies are warranted to better understand epidemiology, transmission, pathology, and possible reservoir status in this species.
