In industrialised countries, inclusion conjunctivitis of the newborn is now known to be just one manifestation of a more generalised infection with Chlamydia trachomatis. Pneumonia and enteric infection can develop in perinatally infected infants. It is possible that trachoma in developing countries may reflect extraocular infection that may contribute to the high frequency of pneumonia and diarrhoea in infants in these countries. If true, this would explain the short-term effects of topical treatment, since children could reinfect their eyes by autoinoculation from other sites. Thus systemic treatment with macrolides would result in benefits beyond the temporary suppression of eye disease.

Chlamydia trachomatis was recovered from the cervices of 4% (36/900) of pregnant women tested. 20 infants born through chlamydia-infected cervices were followed up for a year, as were 18 infants born to chlamydia-negative mothers. A statistically significant excess of conjunctivitis and pneumonia was found in infants exposed to chlamydia. The attack-rate for inclusion conjunctivitis was 35% (7/20) and for chlamydial pneumonia it was 20% (4/20). Chlamydiae were recovered from 10 of the 20 (50%) exposed infants, and seroconversion was demonstrated in 14 (70%). None of the 18 unexposed infants showed evidence of chlamydial infection. Thus in our clinic 2.8% of all newborns acquired chlamydial infection, with incidence-rates of 14 cases of conjunctivitis and 8 cases of pneumonia per 1000 live births. Neonatal chlamydial infection is thus a major public-health problem warranting a preventive programme based on the fuller provision of diagnostic services and the treatment of infected pregnant women.

The most frequently seen type of infectious ophthalmia neonatorum, inclusion conjunctivitis, is caused by the organism Chlamydia trachomatis. This agent is known to be transmitted sexually. Until recently, the infections produced by C trachomatis were though to be relatively benign. Recent evidence, however, suggests that the organism may produce urethritis and epididymitis in the male; cervicitis, cervical erosions, salpingitis, and puerperal infections in the female; and prematurity and pneumonitis in the infant. An infant who develops ophthalmia neonatorum should be thoroughly evaluated for the presence of a chlamydial infection. In many instances the first evidence of chlamydial infection within the parents will be the development of inclusion conjunctivitis in their newborn infant. Family members of infants with inclusion conjunctivitis who manifest any evidence of clinical disease should be evaluated and treated with appropriate antibiotics.

To learn if Chlamydia trachomatis causes in young infants a distinctive penumonia characterized by chronic, afebrile course, diffuse lung involvement and elevated serum immunoglobulins G and M, 47 black infants four to 24 weeks of age were examined for nasopharyngeal shedding of C. trachomatis and serum immunofluorescent antibody to lymphogranuloma venereum Type I. Nasopharyngeal C. trachomatis was found in 18 of 20 with the pneumonia syndrome, two of 15 with various other illnesses and 10 of 12 with inclusion conjunctivitis but without lower respiratory illness. Chlamydial antibody titers of infants with the pneumonia syndrome were significantly elevated (geometric mean-1, pneumonia vs. conjunctivitis = 24,833 vs. 1024 P less than 0.001). No other commonly recognized respiratory pathogens were consistently associated with the pneumonia syndrome. We believe these findings demonstrate an association between the distinctive pneumonia syndrome and C. trachomatis. This, in turn, is a particular facet of a more general event consisting of frequent colonization of the respiratory tract by C. trachomatis in natally acquired infection.

A pregnant woman and her husband had proved chlamydial genital tract infections. She gave birth to a male infant who developed inclusion blennorrhea (inclusion conjunctivitis of the newborn infant). While on topical chemotherapy for his eye disease, the infant developed pneumonitis. Chlamydiae were recovered from his sputum at a time when conjunctival specimens were sterile. This finding raises the possibility that the agent of inclusion conjunctivitis may cause systemic infections in neonates exposed during passage through an infected birth canal.

Chlamydia trachomatis (C. trachomatis) is now well established as a pathogen of neonatal inclusion conjunctivitis and infantile pneumonia. C. pneumoniae (TWAR) and C. psittaci also cause pneumonia and other respiratory infections. Serum samples from 223 Japanese infants and children with pneumonia were tested for IgM antibodies to C. trachomatis, C. pneumoniae and C. psittaci. IgM antibodies to C. trachomatis were measured by an enzyme immunoassay (EIA) and by a microimmunofluorescence (MIF) test. IgM antibodies to C. pneumoniae and C. psittaci were determined by MIF. Of 223 patients, 48 (21.5%) were positive for IgM antibodies to C. trachomatis, 11 (4.9%) were positive for C. pneumoniae and 5 (2.2%) were positive for C. psittaci. From nasopharyngeal swabs collected from 87 infants with pneumonia (0 to 1 year of age), we attempted to isolate C. trachomatis with tissue culture. C. trachomatis was isolated from 23 (26.4%) of 87 infants with pneumonia, and IgM antibodies to C. trachomatis were detected in 17 (19.5%) of them. Our data suggest a role for chlamydial infection in childhood pneumonia beyond infancy with both C. trachomatis and C. pneumoniae being contributing pathogens.

Chlamydia trachomatis (C. trachomatis), C. psittaci, and C. pneumoniae are now well established as pathogens of respiratory infections including pneumonia. Serum samples from 223 infants and children with pneumonia, 31 patients with adult inclusion conjunctivitis, 16 parents of babies with neonatal inclusion conjunctivitis and others were tested for IgM antibodies to Chlamydiae. Diagnostic kits for chlamydial IgM antibodies (SeroELISA and IPAzyme) have been also evaluated for their diagnostic value. It was found that detection of specific IgM antibodies with SeroELISA has a diagnostic value in chlamydial pneumonias.

The chlamydiae are a genetically diverse group of bacteria with a unique intracellular development cycle. The spectrum of clinical manifestations of Chlamydia trachomatis infections in the female includes cervicitis, acute urethral syndrome, pelvic inflammatory disease, salpingitis and the risk of exposure of infants born through an infected birth canal who may develop inclusion conjunctivitis and/or pneumonia. In order to determine the prevalence of cervicovaginal infections caused by C. trachomatis in female population in Cuernavaca, Morelos, we studied 2,407 sexually active women from a suburban area. Genital specimens were collected from each woman and cultured in McCoy cell monolayers. Detection of the bacteria was done by staining with fluorescein-conjugated monoclonal antibodies (Syva Microtrak, Palo Alto CA). 97 of them were culture-positive for C. trachomatis, with and overall prevalence of 4.02 per cent. The most important clinical symptom observed in 47 of the infected patients was an increased or altered vaginal discharge.

Chlamydiae are Gram-negative bacteria with obligate intracellular reproduction and disability to synthesize high-energy compounds such as ATP. Their cycle of development is unique among the prokaryotes: the host cells, mainly epithelial cells, are infected by so-called elementary bodies (EB) which undergo reorganization to form metabolically active reticulate bodies (RB). These RB multiply by binary fission, and after transition into infectious EB they are released within 48-72 hours. Chlamydiae cause prolonged subclinical infections of the conjunctiva, lung, cervix, and urethra. Complications in newborns are inclusion conjunctivitis, nasopharyngitis and pneumonia; in females, salpingitis, infertility, and perihepatitis; in male patients, epididymitis and prostatitis; and in both sexes, Chlamydiae-induced arthritis. Identification of the pathogenic agent confirms clinical diagnosis; tissue culture identification remains the diagnostic method of choice. Therapeutical drugs are tetracycline, erythromycin, josamycin, and in certain cases quinolone derivatives.

Chlamydia trachomatis and the urogenital mycoplasmas are sexually transmitted microorganisms mutually infecting the sexual partners. Transmission from mother to child occurs in utero or, in particular, perinatally when the delivered child passes through the infected cervix. Diseases of newborns infected by Chlamydia trachomatis are inclusion conjunctivitis or infant chlamydial pneumonia. In very-low-birth-weight infants perinatal infections by urogenital mycoplasmas induce pneumonia, septicemia, and chronic lung disease.
