Abstract

Abstract.

Difficulty in controlling human infection is partly attributed to the presence of non-human definitive hosts. Water buffaloes are a major reservoir for transmission of to humans in China. However, in the Philippines, reports based on microscopic examination of buffalo stool identified a low prevalence of , and mathematical models using these data concluded that water buffaloes are not a major reservoir for transmission of to humans. We collected stool from 81 buffaloes in Macanip, Leyte, the Philippines, and assayed for infection by the Danish Bilharziasis Laboratory technique, the Kato-Katz technique, miracidia hatching, and a highly validated real-time polymerase chain reaction. The prevalence defined by each assay was 3.7%, 3.7%, 0%, and 51.5% respectively. Our results demonstrate that microscopic-based techniques dramatically underestimate the prevalence of infection in water buffaloes in the Philippines and warrant reexamination of the role of bovines in transmission of to humans in the Philippines.
