[Kinetic study of the antibodies in OF 1 and C57Bl mice infected with Chlamydia trachomatis and Chlamydia psittaci. Its application to the interpretation of the serological results in human chlamydioses].

The kinetics of antibodies to C. trachomatis and C. psittaci was studied in OF 1 and inbred C 57 Bl mice, inoculated intravenously (IV) or intraperitoneally. Antibodies were detected by a micro-immunofluorescence (MIF) test. Antibody kinetics depends on many factors (genetic particularities of the mice, route of inoculation, chlamydial strain). The response is more specific when mice are inoculated with C. trachomatis than with C. psittaci; heterospecific antibodies appear later in C 57 Bl mice than in OF 1 mice inoculated IV with C. trachomatis. These results are used to explain the serological findings in 6 cases of human chlamydial infections. The type, species and genus specificities of antibody responses to chlamydial infections are discussed.
