[Cleaning and molluscicide treatment for schistosomiasis control]

We evaluated the effect of niclosamide treatment and the additional cleaning of basins and pools on the density and infection rate of Bulinus truncatus within the irrigation network of Oudaya. The period prior to molluscicide treatment [January-May] revealed a mean density of 151 snails/m2 in 1995-96 and 127 snails/m2 in 1997-98. After cleaning had started, the mean density prior to molluscicide treatment fell to 84 snails/m2 in 1999-2000. After molluscicide treatment, densities dropped to very low levels only rising again from October. In November 1999-96 mean density reached 150 snails/m2 but after cleaning started in 1997-98 this only reached 80 snails/m2; in 1999-2000, when cleaning was undertaken 3 months before and after molluscicide treatment, it reached only 18 snails/m2. From 1995 to 1996, the infection rate rose slightly [4.54% to 5.44%], but, from 1997, there was a significant drop [3.13% to 2.16%]

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

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
