Monoclonal antibodies in serovar determination of 53 Chlamydia trachomatis isolates from Amiens, France.

The serovar distribution of 53 Chlamydia trachomatis strains obtained from 53 clinical isolates in Amiens (France) was studied by a micro-immunofluorescence test with a panel of 15 monoclonal antibodies. The isolates were of ocular (babies) or urogenital origin (adults). This typing showed that E was the most common serovar (62.3%) followed by F (9.4%), Ba, D, J (5.6%), H (3.8%) and G, K (1.9%). Two mixed infections were detected (one EG and one FG). Consequently, the serovar distribution of C. trachomatis in Amiens (France), was characterized by a predominance of serovar E higher than in other European countries.
