Mycoplasma hominis in pelvic inflammatory disease

Fifty one cases of Pelvic Inflammatory disease (PID) and sixty one control subjects were screened for the genital mycoplasmas. Cervical swabs, urine & blood were collected from the patients and the control subjects and were processed by standard techniques for isolation and identification of bacteria, fungi and mycoplasmas. The rate of isolation of M. hominis from the PID and controls were 54.90% and 16.39% respectively, and this difference was statistically significant (p. < 0.001). Metabolic inhibition test revealed a titer of > 1:2 in 92% of the acute sera of PID against the homologous strain and there was a rise or fall in four fold titer in 45% of the convalescent sera tested for.
