Multilocus sequence typing identifies an avian-like Chlamydia psittaci strain involved in equine placentitis and associated with subsequent human psittacosis (original) (raw)

Chlamydia psittaci, a pathogen primarily associated with avian species, was identified as a potential cause of equine placentitis following exposure incidents among veterinarians in Australia. The study isolated a strain of C. psittaci from abnormal equine fetal membranes, revealing its identity as belonging to the virulent 6BC clade, thus posing significant implications for both equine health and public safety due to possible zoonotic transmission to humans. It underscores the necessity for heightened biosecurity and further investigations to elucidate the dynamics of transmission and infection.
