Etiología de las infecciones respiratorias agudas bajas en lactantes hospitalizados. 3a- parte: investigación de Chlamydia trachomatis

Abstract

Chlamydia trachomatosis pneumoniaFive infants with Chlamydia trachomatis associated pneumonia are analized. They were diagnosed out of 80 infants admitted to the hospital with pneumonia whose etiology was studied for virus, bacteria and Chlamydia trachomatis. Serum IgM antibodies to Chlamydia tr. were measured by indirect immunofluorescence (IIP), wich is considered to be specific in high titers (1 > 32). The five cases represented 10.4% of infants studied younger than six months. One child was born by cesarean section suggesting the posibility of other non oculogenital still undefined mechanism of transmission. Clinical symptoms and laboratory findings were characteristics of those described in Chlamydia tr. pneumonia. Chlamydia trachomatis must be considered an etiologic agent in infantile pneumonia specially in the first six months of life. The high specificity and sensitivity of the IFF makes this serologic test the best non-invasive method for diagnosis of Chlamydia tr. pneumonia currently available.
