[Detection of chlamydia in the intestines and lungs in pigeons and humans]

Attempts were made to detect Chlamydia sp. by direct immunofluorescence (IF) in intestinal and lung tissues collected from wild town pigeons, young reared pigeons, and human corpses. Chlamydia in any organ were detected in 86.6% of the 427 adult pigeons and 27.3% of 16 young pigeons. Positive IF results were in intestinal and lung samples, collected from 427 adult pigeons, in 34.3% and 40.05% of the birds, respectively. Human (n = 100) intestinal and lung tissues were positive in 22% and 20% of the corpses, respectively. Titres 1:20 and higher were demonstrated by CF in 53.86% of the 427 adult pigeons. The highest titre found was 1:5 120.
