Abstract
Background and Aim: Trichuris trichiura and Hymenolepis diminuta are helminthic intestinal parasites that infect humans and other animals, including non-human primates. However, molecular detection of these parasites remains scarce in long-tailed macaques (Macaca fascicularis), which coexist with human communities in Thailand. Thus, this study aimed to molecularly confirm the occurrence of Trichuris spp. and Hymenolepis spp. infection and determine the species of both parasites that were found in long-tailed macaques.
Materials and Methods: A total of 200 fecal samples were randomly collected from long-tailed macaques living in Lopburi, Thailand, and tested based on polymerase chain reaction (PCR) assays for Trichuris spp. and Hymenolepis spp. infections. The PCR products were submitted for DNA purification and sequencing. Phylogenetic analysis was performed using the maximum likelihood method.
Results: Of 200 tested samples, three (1.5%) were positive for Trichuris spp. Sequence analysis of all positive samples revealed the presence of T. trichiura, while eight samples (8/200, 4%) positive for Hymenolepis spp. were classified as H. diminuta. No significant associations were found between parasite infection and sex of macaques.
Conclusion: This study revealed that long-tailed macaques harbor T. trichiura and H. diminuta. These results suggested that local residents and tourists must pay attention to limiting contact with long-tailed macaques and take hygienic precautions to reduce the risk of zoonotic and anthroponotic transmission of these parasites between humans and long-tailed macaques.
