In the recent reports, Cps infection in birds was usually reported as a part of (a) the zoonotic event, such as that of molecular characterisation of Cps isolated from a crimson rosella from the same human psittacosis endemic region [90] or (b) horse psittacosis investigations, such as that of an opportunistically characterised archival Cps-positive sample taken from a spotted dove [86]. This evidence concerns the gene CAD and ornithosis.
