Isolation of Psittacosis Agents from Follicular Conjunctivitis of Sheep

SummaryPsittacosis - lymphogranulomatrachoma agents were isolated from conjunctival scrapings from 9 of 17 sheep representing 3 different flocks afflicted to 90% with follicular conjunctivitis. The PLT agent isolated from follicular conjuctivitis was specifically related to those causing polyarthritis. Ten to 25% of the sheep with eye lesions had polyarthritic signs and the PLT agents were isolated from the blood of 6 of the 17 sheep tested. Parenteral inoculation resulted in follicular conjunctivitis and polyarthritis.
