[Vaginal infections due to non-fastidious germs: place of Gardnerella vaginalis]

ABSTRACT

Gardnerella vaginalis is the most common frequently involved cause of bacterial vaginosis. The purpose of this study is to determine the frequency of G vaginalis infection among other non-fasidious etiological causes in women suffered from vaginosis diagnosed in our laboratory. Results were compared with data of literature, and discussed for guiding the best management of these infections. We analyzed the registered data of microbiological results of examined vaginal discharges over a period of three years.[2001-2003]. Positive diagnosis, of G. vaginalis vaginosis depends on the evident detection of clue cells microscopically in a Gram stained smears according to Amsels criteria. The results were often given in the same day. And as the current treatment depends on metronidazole, we rarely used culture sensitivity tests. Among 219 vaginal smears, 125 [57%] were positive, and 143 micro-organism incriminated- ni leukorrhoea were detected in our patients [210 out patient [96%] and [4%] inpatient]. Candida albicans was responsible for [28-19.6%], followed by G. vaginalis [23-16.1%] and lastly Escherichia coli [18-12.6%]. G. vaginalis-related vaginosis is frequent. It represents, the second etiological cause inducing vaginal discharge among the non-fastidious germs diagnosed in our hospital. As there is a recent reports show an in-vitro resistance and also the presence of a therapeutic failure using metronidazole in treating G. vaginalis infections, insistence of using a culture on an appropiate media in order to identify the germ and test sensitivity to antibiotics used in treating these infections must be performed following the simple way of laboratory detection
