Molecular prevalence of Chlamydia spp. in wild birds from Qinghai Lake, China.

ABSTRACT: Chlamydia spp. are a group of gram-negative, obligate intracellular bacteria that represent significant pathogens causing chlamydiosis in both animals and humans. Avian chlamydiosis (AC), primarily caused by Chlamydia psittaci, C. avium, C. gallinacea, and C. ibidis, has been documented in over 460 avian species. Qinghai Lake, China's largest saltwater lake and a critical overwintering site for migratory birds, served as the study area to investigate Chlamydia prevalence in wild birds. Fecal samples from 125 birds revealed an overall Chlamydia spp. infection rate of 28.8% (36/125), with three species identified: C. abortus (55.6%, 20/36), C. avium (44.4%, 16/36), and C. psittaci (13.9%, 5/36).
