Feline chlamydia and calicivirus infections.

Feline conjunctivitis is common and often presents a clinical challenge to the veterinarian. Chlamydia psittaci is an important pathogen and should always be considered when evaluating cats with conjunctivitis. FCV is an infrequent cause of conjunctivitis and only causes the disease in conjunction with other clinical signs of this infection, such as oral mucosal ulcers and upper respiratory tract disease.
