| Outline of Final Research Achievements |
The molecular taxonomic method was applied in investigations of various protozoan infections in Indonesia, and the endemicity data was epidemiologically assessed from the view of mutual relations with the characteristics, such as age, gender, of target population.
The results showed following findings: (1) All the investigated protozoan groups, Amoebazoa, Fornicata, Parabasalia, and Stramenopiles, were highly endemic in the target site. (2) Age-related and gender-related differences of protozoan prevalences were indicated in targeted student population. (3) Giardial prevalence reduction on aging was attributed to assemblage A prevalence, which was reduced in higher age layers. (4) The endemicity of Pentatrichomonas hominis was maintained by zoonotic transmissions of a specific strain in the area.
Molecular epidemiological methods targeting various protozoan species could improve our understanding of the endemicity of those infections.
