Plain-English summary
A group of cats with eye problems, specifically conjunctivitis (inflammation of the eye), was tested for a type of bacteria called Chlamydophila pneumoniae, which is known to cause respiratory issues in humans. Out of the cats with conjunctivitis, five were found to have this bacteria, along with two others that had a different type of chlamydia. This is the first time this human pathogen has been detected in cats with eye issues. The findings suggest that some cases of conjunctivitis in cats may be linked to this bacteria, highlighting the importance of proper diagnosis and treatment.

Abstract
OBJECTIVE: To determine the presence of chlamydial species including recently described chlamydial agents as well as the human pathogen Chlamydophila pneumoniae in feline conjunctivitis. ANIMAL STUDIED: Twenty five cats without and 49 cats with conjunctivitis were tested for chlamydia using a Chlamydiaceae real time (RT) PCR (targeting the 23S rRNA gene sequence), a Chlamydiales PCR (targeting the 16S rRNA gene sequence), and cell culture. The PCR products of all positive samples were sequenced and subsequently analyzed using a basic local alignment search tool search. RESULTS: Chlamydiaceae RT PCR and subsequent sequence analyses identified C. pneumoniae in five cats in the conjunctivitis group. The presence of Chlamydophila felis was shown in two cats with conjunctivitis. Chlamydiae related to uncultured members of Chlamydiales were detected in three conjunctivitis cases and in one cat without clinical symptoms. CONCLUSION: This study detects for the first time, the known human pathogen C. pneumoniae in feline conjunctivitis cases using Chlamydiaceae RT PCR and sequence analyses.
