Study on Seroprevalence and Leptospiral Antibody Distribution among High-risk Planters in Malaysia.

Objectives: To determine the leptospirosis seroprevalence and to identify the predominant infecting serovars among oil palm plantation workers.

Methods: The cross-sectional study involved 350 asymptomatic oil palm plantation workers in Melaka and Johor. A serological test using the microscopic agglutination test was conducted in the Institute of Medical Research with a cut-off titre for seropositivity of ≥1:100.
