is an intracellular bacterium belonging to the family. Poultry is considered to be the major reservoir of this agent, which has worldwide distribution and a particularly consistent worldwide occurrence in chicken flocks. The bacterium has been linked to respiratory disease in humans but without definitive confirmation; nevertheless, while it has not been proved to be the cause of human respiratory disease, a recent report from Italy verified its bird-to-human transmission.

Wild birds are considered as a reservoir for avian chlamydiosis posing a potential infectious threat to domestic poultry and humans. Analysis of 894 cloacal or fecal swabs from free-living birds in Poland revealed an overall Chlamydiaceae prevalence of 14.8% (n = 132) with the highest prevalence noted in Anatidae (19.

Article Synopsis
  • Enteric infections from Chlamydia psittaci are common in ducks but usually don't show symptoms in the wild, prompting researchers to study its effects by orally infecting ducklings with a field strain.
  • In testing three different doses, they found that only ducklings given the highest dose displayed mild diarrhea, while others showed no significant clinical symptoms.
  • The study revealed that, despite widespread internal organ dissemination of the bacteria, the highest concentrations were found in specific organs like the spleen and liver, with contact birds eventually showing similar bacterial loads, indicating fast transmission between ducks.

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.
