Suspected chlamydial foetal loss highlights the need for standardised on-farm protocols

Chlamydia psittaci (C. psittaci) is a recognised cause of late term equine foetal loss and poses a zoonotic risk in Australia. However, a management strategy is lacking to protect at risk humans handling infected aborted material and pregnant mares. This study proposes a protocol for approaching C. psittaci foetal loss after investigating four foetal losses that occurred on a horse stud in the Hunter Valley, Australia in 2021.
