Vol 8(8), 62-66

In this cross-sectional study, we sought to determine the seroprevalence of leptospirosis among pigs in Grenada. Eleven farms were randomly selected amongst Grenada’s six parishes and blood was collected through venipuncture from a total of 368 pigs. Enzyme-linked immunosorbent assay tests (ELISA) were performed on serum to screen for antibodies to Leptospira spp. Overall, seroprevalence to Leptospira spp. was 23.4% (95% CL 19.3-27.9). The percentage of positive cases based on parish is as follows: St. Mark, 21.6%; St. Andrew, 21.5%%; St. George, 25.7%; St. Patrick, 23.6%; St. David, 31.3% and St. John, 9%. There was no significant difference (p>0.05, χ2) in seroprevalence between males (18.8%) and females (25%). Regular assessment of pigs in Grenada for Leptospira spp. and their role in transmission to humans and other animals is recommended for the sake of public health.
