title: Diagnostic features of chlamydia infection in dairy calves.
abstract: Chlamydia were routinely isolated from a group of calves with pneumonia, systemic disease, and enteric involvement. The most commonly observed lesions were acute interstitial pneumonia, hepatitis, and enteritis. Cultures of sequentially collected nasal and rectal samples from clinically normal calves revealed a large percentage of inapparent infections during, at least, the first 30 days of age.
