Abstract
Cryptosporidium species, causing diarrheal illnesses in humans and animals worldwide, are under investigation for their molecular epidemiology in Japan. The study focuses on detecting Cryptosporidium species in humans, animals, water, and the environment, revealing three species in people: C. parvum, C. meleagridis, and C. hominis. Subtype IIa of the C. parvum gp60 gene is prevalent, indicating potential zoonotic transmission. Animal studies identified sixteen species, mainly cattle and pets, with C. parvum (subtype IIa) common in cattle and C. canis and C. felis prevalent in pets. Additionally, C. bovis and C. ryanae were found in cattle and sika deer. Knowledge gaps exist, particularly in water and environmental source typing, with limited research revealing five species and five genotypes, suggesting a significant role of water in transmission. Further research is needed to understand the molecular diversity and transmission dynamics across humans, animals, water, and the environment in Japan.
期刊介绍：
Parasitology International provides a medium for rapid, carefully reviewed publications in the field of human and animal parasitology. Original papers, rapid communications, and original case reports from all geographical areas and covering all parasitological disciplines, including structure, immunology, cell biology, biochemistry, molecular biology, and systematics, may be submitted. Reviews on recent developments are invited regularly, but suggestions in this respect are welcome. Letters to the Editor commenting on any aspect of the Journal are also welcome.
