Identification of a Chlamydia trachomatis Serovar E Urogenital Isolate Which Lacks the Cryptic Plasmid

ABSTRACT

Our laboratory recently recovered Chlamydia trachomatisin tissue culture from a urogenital specimen which tested negative by commercial plasmid-based PCR. Immunotyping and omp1sequencing identified the isolate as a serovar E isolate. Further investigation by PCR and Southern hybridization indicated that this isolate lacks the chlamydial cryptic plasmid.
