Cryptosporidium chipmunk genotype I, a zoonotic pathogen, can now be subtyped using new genetic markers. This helps understand its spread from animals to humans, revealing genetic similarities between wildlife and human isolates.
Area of Science:
- Genomics
- Parasitology
- Zoonotic Diseases
Background:
- Cryptosporidium chipmunk genotype I is an emerging zoonotic pathogen.
- Current lack of subtyping tools hinders understanding of zoonotic transmission's epidemiological role.
Purpose of the Study:
- To identify genetic markers for subtyping Cryptosporidium chipmunk genotype I.
- To develop a subtyping tool to investigate zoonotic transmission.
Main Methods:
- Whole-genome sequencing of a human Cryptosporidium chipmunk genotype I isolate.
- Selection and validation of two genetic markers: gp60 and a mucin protein (cgd1_470 ortholog).
- Application of the subtyping tool to human, wildlife, and water samples.
Main Results:
- Genome sequencing yielded 9,509,783 bp in 853 contigs with high coverage.
- Fifteen gp60 subtypes and two mucin subtypes were identified, primarily varying in repeat regions.
- Genetic similarity observed between human and wildlife Cryptosporidium chipmunk genotype I isolates.
Conclusions:
- Developed a novel subtyping tool for Cryptosporidium chipmunk genotype I.
- Findings suggest potential zoonotic transmission plays a role in human infections.
- Genetic similarities support the link between wildlife and human Cryptosporidium chipmunk genotype I strains.
