  • Title: Effect of vaccination on feline Chlamydia psittaci infection.
    Author: Wills JM, Gruffydd-Jones TJ, Richmond SJ, Gaskell RM, Bourne FJ.

    Abstract:
    Experimental ocular infection of specific-pathogen-free cats with the feline pneumonitis strain of Chlamydia psittaci produced an acute, severe conjunctivitis characterized by blepharospasm, conjunctival hyperemia, chemosis, and ocular discharge. Organisms were recovered from the conjunctiva for several weeks, and persistent genital and gastrointestinal infection also resulted from the ocular infection in some cats. Subcutaneous vaccination with live feline pneumonitis C. psittaci 4 weeks before ocular challenge significantly reduced the severity of the conjunctivitis. However, there was no effect on shedding of organisms from the eye or on the transmission of infection to the gastrointestinal and genital tracts. It is suggested that the acute stage of this ocular disease is caused largely by release of pathogenic antigen(s) from chlamydia-infected conjunctival cells, rather than by a direct cytopathic effect of chlamydial replication. Thus, vaccination with whole live organisms reduced the acute disease in experimentally infected cats but did not prevent shedding of the organism. The implications of these findings are discussed.
