Interpretive Summary:

Technical Abstract: Chlamydiae have occasionally been isolated from swine fro over 40 years, but the isolates have not been characterized or inoculated back into swine to determine their ability to cause disease. We have six different strains of chlamydiae from cases of enteritis, pneumonia, and conjunctivitis in 2 to 6-week old pigs. These isolates are all of the C. trachomatis type and are similar but not the same as the human C. trachomatis strains. Fou of the isolates were used to inoculate gnotobiotic pigs. A respiratory isolate when inoculated intratracheally caused pneumonia in pig. Two enteric isolates produced enteritis when fed orally, and a conjunctivitis isolate produced a mild to moderate conjunctivitis when inoculated into the conjunctival sac. All of the inoculated pigs developed enteritis. The research demonstrated that chlamydiae is a pathogen in pigs and that it can produce enteritis, pneumonia, and conjunctivitis.
