Partial Characterization of Chlamydia trachomatis Isolates Resistant to Multiple Antibiotics

Abstract

In vitro susceptibility testing was done on urogenital isolates of Chlamydia trachomatis from five patients, four of whom were suspected treatment failures. At least one isolate from each patient wasresistant to tetracycline at concentrations ⩾8 p.g/ml, although C. trachomatis and may be a factor in some treatment failures.
