Cross-reactivity between Chlamydia trachomatis heat shock protein 10 and early pregnancy factor.

Chlamydia trachomatis heat shock protein 10 (Chsp10) is associated with chronic genital tract infection with C. trachomatis. Chsp10 is homologous to human chaperonin 10 (Cpn10) and early pregnancy factor (EPF), a form of human Cpn10 that is specifically secreted at the start of pregnancy.

Evaluation of the erythrocyte and platelet morphological analysis given by the hematology analyzer Coulter STKS.

The morphological profiles of red blood cells (RBC) and platelets (Plt) derived from the distribution analysis given by the Coulter STKS were evaluated in two groups of patients suffering from non hematological (n = 293) and hematological (n = 257) conditions. The RBC and Plt flags were studied in terms of sensitivity of the morphological analysis and specificity and significance of each flag. When all RBC and Plt flags were considered, the percentages of false negatives and false positives in our subjects were found to be 4.
