Investigation of potential zoonotic transmission of cryptosporidiosis in southern India

Abstract

The common species and subgenotypes causing cryptosporidiosis were studied in 394 children and 627 animals with diarrhea in Vellore in southern India. Although no zoonotic strains were identified in 13 infected children, 1 of 12 infected animals had C. hominis, indicating the potential for cross-species transmission. This study also reports C. xiaoi for the first time in India.
