Abstract
A Chlamydia trachomatis urethral isolate, alpha/95, yielding pgp3-negative but otherwise normal inclusions by immunofluorescence also gave negative results when pCT-homologous DNA was searched by PCR and Southern blotting. omp-1 sequence analysis identified alpha/95 as a new genotype B variant. These findings confirm that pCT is not required for chlamydial growth in vitro.
