Four different types of contact tracing for partners of Chlamydia trachomatis infected patients were compared with respect to reinfections during two 15-month periods in 1979/80 and in 1983/84. Between the two study periods a gradual improvement in contact tracing occurred. No reduction in overall reinfections was observed in the second period, reinfections occurring within 12 weeks were similar in the two periods. Treatment of the regular partner (by giving the woman a prescription for her partner) without examination or further partner follow-up resulted in few reinfections. A system of partner referral without verification that partners actually appeared for examination resulted in significantly more reinfections by the regular partner than a system with non-mandatory verification: 60 of 997 women (6%) compared with 6 of 645 (1%). The addition of C. trachomatis infection to the existing STD legislation resulted in fewer identified partners refusing examination than previously, one of 254 men (0.4%) compared with 40 of 223 (18%) before legal inclusion.

Bacterial pathogens account for a significant portion of the current STD epidemic in the United States. Gonorrhea, syphilis, and chancroid are especially rife in the nation's poverty pockets. Chlamydial infection, the most common bacterial STD, is prevalent at all socioeconomic levels. A recurrent theme in these diseases is coexisting infection, sometimes involving HIV.

The incidence of Chlamydia infection and factors associated with it in 193 women consulting for infertility was analyzed in comparison with 210 matched controls. All study subjects received a clinical exam, history interview, Pap test, vaginal bacteriology, colposcopy, cervical virology for Chlamydia and enzyme-linked assay for Chlamydia, herpes, rubella and toxoplasma antibodies. Results were tabulated as percent distributions for Chlamydia-positive and -negative in index cases and controls, broken down by the descriptive factors, age at 1st intercourse, number of partners, socio economic class and numbers of induced abortions. 43.5% of the index cases had primary infertility, 21.7% had secondary infertility and 34.8% were sterile. 11.9% of the study group were positive for Chlamydia infection, compared to 5.7% of controls. The only significant difference in factors related to STD infection were: earlier age at 1st intercourse among controls; higher percentage with 3 sexual partners, higher socioeconomic class and more induced abortions in the study group of infertile women; but no difference in chlamydia infection rates with abortion history. This study is unusual in finding higher socioeconomic class in the infertile women than in controls.

Two commercial test kits, Pharmacia Chlamydia EIA (PhEIA) and IDEIA Chlamydia Test, for the identification of Chlamydia trachomasis and McCoy cell culture were compared in urogenital specimens. The sediments of the transportation buffers of specimens with discordant results were investigated for elementary bodies (EB) with fluorescein-labelled antichlamydial antibodies. The prevalence of chlamydial infection among the men was 16% (48 of 293), 47 culture positive and one EB positive, and among the women 10% (10 of 97), 10 culture positive. In men, the sensitivity of PhEIA, IDEIA and culture was 71%, 40% and 98%, respectively. In women, irrespective of site, corresponding figures were 100%, 80% and 100%. The specificity and positive predictive values were 100% for both enzyme immunoassays in men and women. The low sensitivity of IDEIA could not be explained by the degree of infection as measured by the number of inclusion bodies in cell culture, the presence of antigen as measured by the number of EBs or the sampling order.

In a microbiological study of the urethral flora in men with non-gonococcal urethritis (NGU), Chlamydia trachomatis (isolated from 30% of men) was the only organism isolated significantly more often from men with NGU than controls (P less than 0.01). Bacteroids species, especially of the melaninogenicus-oralis group, were the predominant anaerobic bacterial isolate from both men with NGU (isolated from 24%) and controls (isolated from 30%). There was no evidence that aerobic bacteria, anaerobic bacteria or herpes simplex virus made a significant contribution as primary pathogens in non-chlamydial NGU. Gram-positive cocci were the only anaerobic organism isolated more often from chlamydia-positive men (29%) than chlamydia-negative men (16%) with NGU (P less than 0.01). The significance of this remains unclear.

Chlamydia trachomatis can be identified in up to 60% of cases of nongonococcal urethritis (NGU) and the aetiology of most of the remainder is obscure. This paper reports a role for other genitourinary (GU) infections such as candidiasis, warts and herpes simplex, in the causation of NGU. One hundred and ten men fulfilled the entry criteria which included the probability that their contacts would attend the department. Fifty-four of the 110 men had GU infections other than NGU; 56 had no other infections. NGU was detected in 31 (57%) of cases with other GU infections and 8 (26%) were chlamydiae-positive: in contrast NGU was found in only 10 (18%) of those with none of the other infections and 3 (30%) were chlamydiae-positive. Chlamydiae-negative NGU was, therefore, more common in those with other GU infections. Forty-five (86%) of 52 contacts of 41 patients with NGU had various GU infections such as candidosis and anaerobic vaginosis, in contrast with other GU infections in only 7 (23%) of 30 contacts of men with no other GU infections. Other GU infections in patients and their contacts appeared significantly related to the presence of chlamydiae-negative NGU.

Chlamydiazyme (Abbott), an enzyme-linked immunoassay (EIA), was evaluated using cell culture on Hela 229 cells as the method of reference. Samples were acquired from 611 female and 280 male patients attending the outpatient clinic for sexually transmitted disease at the University Hospital in Rotterdam, The Netherlands. The prevalences of chlamydia culture-positive female and male patients were 7.8% and 14.4% respectively. The overall sensitivity and specificity values of the EIA were respectively 68.1% and 95.8% in the female and 92.1% and 92.0% in the male population. Samples which were culture-negative but EIA-positive were re-examined by a second direct test (IDEA; Boots Celltech). If the samples from 12 females and 11 males which were negative on culture but positive with both direct tests are considered as failures of cell culture, the sensitivity of the EIA in females almost equalled cell culture (74.6% versus 79.9%) and in males was even higher (93.9% versus 77.6%). Serotyping of the cultured strains revealed that all serovars of Chlamydia trachomatis occurring in this study could be detected by the EIA. The EIA offers a relatively simple and rapid test for diagnosis of C. trachomatis infections in high-risk populations.

Over a 4-year period a total of 8974 women were screened for Neisseria gonorrhoeae and Chlamydia trachomatis. There were 489 cases of cervical gonorrhoea, 261 serogroup WI and 228 serogroup WII/III. A total of 169 (34.6%) cases had a dual infection with C. trachomatis, 92 from the WI serogroup and 77 from the WII/III. Using Fisher's exact test, no statistically significant difference was observed in the rates of chlamydial carriage between the two serogroups (P = 0.39). These findings are at odds with previously reported data, which suggested a biological interaction resulting in a positive correlation between colonization with serogroup WI and C. trachomatis. Possible reasons for the difference between the findings are discussed.

Chlamydia trachomatis infection, presumably sexually transmitted, has been implicated in the spread of tubal infertility and ectopic pregnancy. In searching evidence of Chlamydia trachomatis infection as a possible cause of tubal ectopic pregnancy, we enrolled 40 consecutive pathologically proven tubal ectopic women and 37 normal early intrauterine pregnant women from our OPD and ward from Jan. 1989 to July 1989. All cases underwent a structured interview giving particular attention to past reproductive history, contraception history and past history of STD. The levels of serum antibody IgG to Chlamydia trachomatis in all cases were determined. Seven ectopic women with wearing IUD in situ (group A) and 33 ectopic women with no identical factor (group B) were compared with 37 normal early intrauterine pregnant women (control group). The result showed group B more often had IgG antibody to Chlamydia trachomatis than control group (P = 0.001). Group A had higher antibody to Chlamydia trachomatis than control group but the difference was not statistically significant (P greater than 0.05). We concluded that the above findings add to the evidence that Chlamydia trachomatis infection is a major cause of tubal ectopic pregnancy.

Aspects of sexually transmitted diseases (STDS) peculiar to the developing countries in South America and sub-Saharan Africa are discussed. The most common STD infections are N. Gonorrhoeae, Chlamydia trachomatis, T. pallidum and T. vaginalis. Vertical transmission, particularly of syphilis among prostitutes, and of Chlamydia and gonorrhea after ophthalmia neonatorum, are common. Chlamydia is also a common respiratory tract infection in African neonates. Late complications of STDs, infertility and ectopic pregnancy, and particularly pelvic inflammatory disease, are responsible for a high proportion of hospitalizations. Antibiotic resistant gonorrhea strains are common, a result of poorly managed antibiotic treatment. Genital ulcer diseases (GUD), which predispose to HIV infections, are more common in Africa than in developed countries, not only herpes but chancroid, donovanosis and lymphogranuloma venereum. Chancroid, caused by Haemophilus ducreyi, causes 36-49% of ulcers in 2 reports. The L1-L3 strains of Chlamydia trachomatis cause lymphogranuloma venereum, the agent responsible for ulcers in 3.6-6.1% of 2 clinic populations. HIV infections have an equal sex ratio in Africa, with a younger age incidence in women and a high vertical transmission rate, while in Latin America, bisexual men, and increasingly, heterosexual transmission by intravenous drug users is reported. There is also an HIV-2 virus, whose virulence is in question, common in West Africa.
