title: [Serodiagnosis of Chlamydia trachomatis and Chlamydia pneumoniae. Evaluation comparing 2 methods: microimmunofluorescence and ELISA. A study of 216 Congolese sera].
abstract: Our purpose was to compare two assays for C. trachomatis and C. pneumoniae serology: immunofluorescence and ELISA. With both assays, we tested 216 sera from two populations: risk population of STD (sexually transmitted disease) (women) and a control population "blood donors". Positives percentages of each population were compared by two assays: 87% in MIF and 76% in ELISA (women population); 64.8% in MIF and 53.7% in ELISA (blood donors population). Results were not significantly different. In comparison with ELISA: MIF had a sensitivity of 85% and a specificity of 93%. In comparison with MIF: ELISA had a sensitivity of 98% and a specificity of 48%; agreement between MIF and ELISA in women population and blood donors population is respectively: 88.9% and 78.8%. The discrepancy between both methods is 11.1% in women group and 21.2% in blood donors group. The correlated coefficient (r) between MIF and ELISA was ranged between 0.507 and 0.778 (P < 0.001). Both assays have honourable performance, but no superimposable.
