The prevalence of urogenital infection caused by Chlamydia trachomatis was examined in 100 non-pregnant women with cervicitis, and 100 healthy women, in San Salvador City, El Salvador. Pharmacia Chlamydia EIA test was used for the detection of chlamydial antigen in urethral and cervical specimens from all the women. Direct immunofluorescence was used for confirmative tests on the EIA positive and the negative gray zone samples. C. trachomatis antigen was detected in 28% of the women with cervicitis compared with 5% in the group of healthy women ( P < 0.001). The cervicitis group were also screened for Neisseria gonorrhoeae which was isolated from 12% of them. One strain out of 12 was beta-lactamase producing (PPNG). Five per cent of the women with cervicitis had simultaneous C. trachomatis and N. gonorrhoeae infections.

ABSTRACT An immunohistochemistry method using formalin-fixed tissues, a direct immunofluorescence method using cryostat sections, an enzyme-linked immunosorbent assay (ELISA), and a PCR method were compared for diagnosis in a litter of weaned pigs that had been experimentally inoculated with wild-type porcine epidemic diarrhea virus (PEDV) and killed between 6 and 60 h after onset of diarrhea. The immunohistochemistry method proved to be as reliable as direct immunofluorescence for diagnosis of PEDV in tissues collected postmortem. The good reliability of ELISA for investigating clinical samples was confirmed, whereas the PCR method used was ineffective.

The results of Chlamydia trachomatis detection in different urogenital samples (vagina, cervix, urethra, urine) are presented in this report. The study was carried out for the period of 1999 to 2000. A total of 397 women and 253 men were examined. Cervical, urethral and vaginal swabs from women, and urethral, first voided urine (FVU) specimens from men were tested. For diagnosis of Chlamydia, trachomatis the following methods were used: polymerase chain reaction (PCR), direct immunofluorescence test (DIF) and cell culture (CC). In male samples, more often chlamydiae were detected in the urethra (11,6%), more rarely - in the FVU (6%). When female samples were tested, more often C. trachomatis was found in the vagina (18,4%), and less often - in the cervix (14. 4) and the urethra (8. 8%). The sensitivity and specificity of the methods used to test urogenital samples were determined. The PCR sensitivity and specificity was shown to be 75 and 100% for C. trachomatis detection in the cervix, 75 and 97. 5% - in the female urethra, and 63 and 99% - in the vagina, respectively. The PCR sensitivity and specificity was found to be 78 and 100% in the male urethral specimens and 100 and 99. 6% in the FVU, respectively. The sensitivity of cell culture method used for chlamydiae detection in cervical, female and male urethral samples was low - 33. 9, 47. 1 and 50% respectively. The CC specificity was 100%.
