Clinical Significance
C. trachomatis is associated with infections of the mucous membranes of the urogenital system, the upper respiratory tract and the eye. It may be sexually transmitted; resulting diseases include urethritis, cervicitis, salpingitis, epididymitis, proctitis and lymphogranuloma venereum. C. pneumoniae is associated with both upper and lower respiratory infections. Infections of the upper respiratory tract and eye usually occur in newborns exposed at parturition. In adults, eye infection may be transmitted by hand after contact with secretions. Isolation by tissue culture is recommended when testing individuals for legal purposes.
