Molecular survey for Chlamydia among southern greater gliders (Petauroides volans) from southeastern New South Wales, Australia

Southern greater gliders (Petauroides volans) are endangered Australian marsupials for which there is little health data currently available. Chlamydia pecorum is the only reported pathogen of greater gliders and infects a broad range of hosts, including other marsupials, ruminants, swine and birds. Conjunctival and cloacal swabs collected from thirty-two southern greater gliders across southeastern New South Wales, Australia were screened for Chlamydia spp. by 23S real-time PCR. None of the ninety-six swabs tested returned a positive result for Chlamydia DNA. We found no evidence of Chlamydia infection among the four geographically disparate populations sampled, suggesting that Chlamydia may not pose a widespread health risk to southern greater gliders in this region, based on the current data. However, various clinical signs of ophthalmic pathology were observed, warranting further investigation to determine their underlying aetiology.
