[Seroprevalence of toxoplasmosis among women having spontaneous abortion and pregnant women following in a center of health up-town in Dakar]. / Séroprévalence de la toxoplasmose chez les femmes victimes d'avortement spontané et chez les femmes enceintes suivies dans un centre de santé de la zone sub-urbaine dakaroise.

A prospective survey carried on 70 women having a spontaneous abortion and 70 pregnant women was achieved in the center of health Roi Baudouin of Guediawaye (Senegal) between November 2001 to April 2002 to study the toxoplasmosis in the two groups. Anti-toxoplasmosis antibodies were searched for on all women by a technical solid-phase enzyme immunoassay. The solid-phase is a combs. The seroprevalence of the toxoplasmosis is 37.1% among women having aborted and 40% for pregnant women. The difference is not statistically significant (p = 0.729). The seroconversion is 22.8% among women having aborted and 10% for pregnant women. The difference is statistically significant (p = 0.041). The research of factors favoring the infestation, related to through food habits, pleads in favor of a contamination during childhood, essentially soil and/or eating undone meat. With regard the high percentage of not immunized women (62.9% for women having aborted and 60% for pregnant women), it is necessary to take prophylactic measures to prevent congenital toxoplasmosis.

[Prevalence of intestinal parasitis at the King Baudouin health center of Guediawaye (Senegal)]. / Prevalence des parasitoses intestinales au centre de santé roi Baudouin de Guediawaye (Sénégal).

A prospective study carrying on 302 samples of stools of aged children of 0 to 15 years has been achieved between January 02 and April 11 2001 in the center of health Roi Baudouin of Guediawaye (SENEGAL) to appreciate the prevalence of intestinal parasitis. For every child, we made a scotch test, a macroscopic exam of stools and a microscopic exam to the direct analysis and after concentration by the method of RITCHIE simplified. The global prevalence is 56,62%. Ascaris lumbricoides arrived in head with 34,17%, follow-up of Giardia lamblia (22,50%), Trichirus trichiura (22,08%) and Amoeba (14,58%). The prevalence varied with age and the children who are 11 to 15 years have the indication of infestation the most elevated (75,86%): The difference of prevalence to the sex and according to the presence or no current water is not meaningful. On the other hand topics to weak standard of living have an indication elevated parasitis with 66,05%. So measures of efficient struggle must be undertaken to combat these intestinal parasitis.

[Micromethod for identification of enterobacteria]. / Microméthodes d'identification des Enterobactéries.

The aim of this study was to set accurate and reliable methods in the identification of Enterobacteriaceae. In Micro CSB Entero each of a strip with 20 cupules containing dehydrated substrates for biochemical identification of bacterial species. Strips were inoculated with 100 microliters per cupule and incubated. After 18 hours, reagents were added. Baye's theorem was used to validate tests. Reactions from Micro CSB were cleared and easily read. 102 strains of Enterobacteriaceae were identified by MicroCSB--89.3% were correctly identified. 0.9% were identified with other tests 9.8% were incorrectly identified MicroCSB gives many advantages: This method save time, space and is less expensive than the other methods and it gives security for identifying species belonging to the different genera.
