Chlamydophila psittaci, an obligate intracellular pathogen, has been associated with psittacosis.Also, C.psittaci is a zoonotic agent.CPSIT_0846, a putative transmembrane head (TMH) family protein, was detected in the inclusion membrane during C.psittaci infection with antibodies raised with CPSIT_0846 fusion proteins by immunofluorescence assay.In the time-course monitoring, RT-PCR and Western blot revealed that it could be present as early as 2 h post infection (hpi), while it was visualized in inclusion membrane at 18 hpi in immunofluore...
