Draft genomes of novel avian Chlamydia abortus strains from Australian Torresian crows (Corvus orru) shed light on possible reservoir hosts and evolutionary pathways.

ABSTRACT: Chlamydia abortus, an obligate intracellular bacterium, is a major causative agent of reproductive loss in ruminants, with zoonotic potential. Though this pathogen is primarily known to infect livestock, recent studies have detected and isolated genetically distinct avian strains of C. abortus from wild birds globally. Before this study, only five avian C. abortus genomes were publicly available. Therefore, we performed culture-independent probe-based whole-genome sequencing on clinical swabs positive for avian C. abortus obtained from Australian Torresian crows (Corvus orru) in 2019 and 2020. We successfully obtained draft genomes for three avian C. abortus strains (C1, C2 and C3), each comprising draft chromosomes with lengths of 1 115 667, 1 120
