Aim: To determine the prevalence and antibiotic susceptibility of Haemophilus influenzae and H. parainfluenzae isolated from the urinary and genital tracts.
Methods: Identification of strains bacteria Haemophilus spp. was carried out by using API NH identification system, and antibiotic susceptibility was performed by Kirby-Bauer disk diffusion method.
Results: A total number of 50 (0.03%) H. influenzae and 14 (0.01%) H. parainfluenzae (out of 180, 415 samples) were isolated from genitourinary tract. From urine samples of the girls under 15 years of age these bacteria were isolated in 13 (0.88%) and two (0.13%) cases, respectively, and only in one case (0.11%) of the UTI in boys (H. influenzae). In persons of fertile age, it was only H. influenzae bacteria that was found in urine samples of the five women (0.04%) and in three men (0.22%). As a cause of vulvovaginitis, H. influenzae was isolated in four (5.63%), and H. parainfluenzae in two (2.82%) girls. In persons of fertile age, H. influenzae was isolated from 10 (0.49%) smears of the cervix, and in nine (1.74%) male samples. H. parainfluenzae was isolated from seven (1.36%) male samples. (p < 0.01). Susceptibility testing ofH. influenzae and H. parainfluenzae revealed that both pathogens were significantly resistant to cotrimoxasol only (26.0% and 42.9%, respectively).
Conclusion: In the etiology of genitourinary infections of girls during childhood, genital infections of women in fertile age (especially in pregnant women), and men with cases of epididimytis and/or orchitis, it is important to think about this rare and demanding bacteria in terms of cultivation.
