In 573 urethral swabs, 3 Haemophilus influenzae (HI) and 7 Haemophilus parainfluenzae (HPI) were isolated; 7 of the patients had clinical features of urethritis and in 3 another genital pathogen was associated. Biotype IV was the predominant one in HI, and II in HPI. In 6.259 endocervical and/or vaginal swabs 15 HI and 5 HPI were isolated. Three out of the 15 females infected by HI, had clinical features of salpingitis and 8 of vaginitis; 5 of them were carriers of an IUD. In four out of the 5 females with HPI another genital pathogen coexisted, and in the fifth there was an additional non analysable isolate. Biotype I predominated in HI and biotype II in HPI.
