A bedsonial (chlamydial) agent was found to be the cause of an acute follicular conjunctivitis in man. It was resistant to sulfonamides and did not possess an iodine-staining matrix. It was readily recoverable from the patient's conjunctival sac and from a cat believed to have been the host animal. Experimentally, it produced a conjunctivitis in kittens and was readily recoverable from their conjunctival sacs. This agent is believed to be identical with the agent of feline pneumonitis.
