In order to test the antibacterial activity of extracts of some medicinal plants used for treatment of some bacterial infections in Kisangani, study was conducted on twenty traditional recipes using watery extracts and concentrated aqueous extracts. Aqueous crude extracts were obtained according to the method of preparation of traditional healers. The antibacterial activity was determined using classic method of diffusion on agar. Aqueous extract of Carica papaya and Psidium guayava presented a maximum inhibition diameter of 20 mm on one crude of Staphylococcus. With concentrated aqueous crude extracts, the highest inhibition diameter of 19 mm was obtained with the association of Citrus limon and Aframomum laurentii. The T Student test applied to our results showed that the difference is high significant between the two extracts of plants. Future research in this area should be promoted to make available for people effective and cheap products against germs which become more and more resistant to common antibiotics in Kisangani.

Abstract: (french)
Dans le but de tester l’activité antibactérienne des extraits de quelques plantes médicinales utilisées dans le traitement de certaines affections bactériennes à Kisangani, une étude a été réalisée sur vingt recettes traditionnelles en utilisant les extraits bruts aqueux et concentrés. Les extraits bruts aqueux ont été obtenus conformément au mode de préparation des tradipracticiens. L’activité antibactérienne a été déterminée selon la méthode classique de diffusion sur gélose. Il ressort des principaux résultats que l’extrait aqueux de Carica papaya et Psidium guayava a présenté une inhibition de 20 mm de diamètre sur une souche de Staphylocoques. Avec les extraits bruts aqueux concentrés, le plus grand diamètre d’inhibition était de 19 mm avec l’association Citrus limon et Aframomun laurentii. Dans l’ensemble, les extraits bruts aqueux concentrés ont inhibés un grand nombre de souches par rapport aux extraits bruts. Le test T de Student appliqué aux résultats montre que la différence est très significative entre les deux extraits. Les recherches ultérieures dans ce domaine sont donc à encourager en vue de mettre à la disposition de nos populations des produits efficaces et bon marché contre les germes de plus en plus résistants aux antibiotiques courants à Kisangani.
