title: The detection of Chlamydophila psittaci genotype C infection in dogs.
abstract: Reports of canine chlamydiosis are infrequent, possibly because the pathogen is rarely considered to be a cause of disease in dogs. This report presents details of Chlamydophila psittaci infection in four bitches with recurrent keratoconjunctivitis, severe respiratory distress and reduced litter size (up to 50% stillborn or non-viable puppies) in a small dog-breeding facility in Germany. Cell culture and immunofluorescence examination of conjunctival, nasal and pharyngeal swabs revealed chlamydial inclusions. PCR and sequencing of ompA amplification products confirmed the presence of Cp. psittaci genotype C. The zoonotic potential of the pathogen was illustrated by evidence of disease in two children that lived on the premises with the infected dogs. There was circumstantial evidence to suggest infection of dogs and humans may have followed the introduction of two canaries and a parrot to the household. The persistent nature of the chlamydial infection suggests that dogs may be reservoirs of Cp. psittaci, but this putative role and whether or not dogs shed the pathogen require further investigation.
