[Chlamydia trachomatis pneumonia: two atypical case reports].

We report on 2 recent and misleading cases of infants hospitalized for Chlamydia trachomatis pneumonia: the first one, 29 days old, had a clinically relevant presentation but was born by caesarean section; the second one, 43 days old, presented with acute respiratory distress. Microbiological diagnosis was achieved by the specific detection of C. trachomatis by molecular biology from a nasopharyngeal sample. These 2 clinical cases illustrate the need to systematically look for C. trachomatis during bacterial-like pneumonia in infants under 3 months of age.
