Bacterial multidrug resistance causes many therapeutic failures, making it more difficult to fight against bacterial diseases. This study aimed to investigate the antibacterial activity of extract, fractions, and phytochemicals from Plectranthus glandulosus (Lamiaceae) against multidrug-resistant (MDR) Gram-negative phenotypes expressing efflux pumps. The crude extract after extraction was subjected to column chromatography, and the structures of the isolated compounds were determined using spectrometric and spectroscopic techniques. Antibacterial assays of samples alone and in the presence of an efflux pump inhibitor (phenylalanine-arginine β-naphthylamide, PAβN) were carried out using the broth microdilution method. The phytochemical study of P. glandulosus plant extract afforded seven major fractions (A–G) which lead to the isolation of seventeen known compounds. The ethanol extract of P. glandulosus was not active at up to 1024 μg/mL, whereas its fractions showed MICs varying from 32 to 512 μg/mL on the studied bacteria. Fraction C of P. glandulosus showed the lowest MIC (32 μg/mL) on E. coli ATCC8739 strain. Fraction D presented the highest activity spectrum by inhibiting the growth of 90% (9/10) of the studied bacteria. The presence of PAβN has improved the activity of extract and all fractions. Overall, the tested phytochemicals showed low activity against the studied bacteria. The overall results obtained in this study show that some fractions from P. glandulosus, mainly fractions C and D, should be investigated more for their possible use to fight against MDR bacteria.

Within many urban communities, there has been a steady decline in healthy living practices among minority families. This decline is often due to the lack of health services and health knowledge of youth and adults (Shirley, Roark, & Lewis, 2012). In order to better reach these particular audiences it has been suggested by scholars and practitioners to focus on community based programming. Partnerships formed through entities such as universities and community organizations have been shown to be quite successful in creating healthier families. This paper discusses one such program focused on increasing health knowledge of urban families. Activities offered included health screenings and healthy living programming for youth. Program results showed that nearly 95% of youth found the activities informative and gave them ways to think about their health and the health of their families.

Le présent travail avait pour but d’évaluer la productivité de cinq espèces du genre Brachiaria (B. brizantha, B. decumbens, B. humidicola, B. mutica et B. ruziziensis) sous le régime de fauche à intervalle de 30 jours. Après expérimentation en champ dans un dispositif de quatre blocs aléatoires complets, les résultats obtenus montrent que les espèces étudiées diffèrent significativement dans la production de la matière sèche. Elles se classent dans l’ordre croissant de la manière suivante: B. mutica (372,7 Kg MS/ha) < B. decumbens (1077,1 Kg MS/ha) < B. ruziziensis (1483,2 Kg MS/ha) < B. humidicola (1744,5 Kg MS/ha) < B. brizantha (2292,7 Kg MS/ha). En conséquence, B. brizantha est l’espèce locale la mieux indiquée pour la production de fourrage en régime de coupe de 30 jours dans les conditions naturelles de Kisangani.

Le présent travail a pour but d’évaluer le taux et la vitesse de reprise des éclats de cinq espèces de Brachiaria (B. brizantha, B. decumbens, B. humidicola, B. mutica et B. ruziziensis) dans les conditions écologiques de Kisangani. Après expérimentation dans un dispositif de quatre blocs aléatoires complets, les résultats ont montré que le meilleur taux de reprise a été enregistré avec les éclats de souche de B. mutica (95,5%) suivi de B. humidicola (84,6%), B. decumbens et B. ruziziensis (82 et 81% respectivement) alors que B. brizantha reprend assez difficilement (62%). B. mutica reprend plus vite (en moyenne 11 jours après plantation) suivi de B. decumbens, B. humidicola et B. ruziziensis (en moyenne 14, 16 et 15 jours respectivement). B. brizantha reprend plus lentement (en moyenne 20 jours après plantation). Ces résultats montrent que dans les conditions écologiques de Kisangani, B. mutica est mieux indiqué pour servir d’alternative fourragère au bétail en situation d’urgence, notamment en cas de disette due à un retard de retour des pluies. Cependant, l’évaluation de la productivité de ces différentes espèces est en cours.
