This study aimed at assessing the impact of some wells abiotic factors on antimicrobial susceptibility Pseudomonas aeruginosa isolated. A total 14 well waters Douala and Yaoundé towns (Cameroon, Central Africa) were chosen. Fifteen antibiotics used to test with majority belonging β-lactam, aminoglycoside quinolone groups. Result showed that in Douala, electrical conductivity water ranged from 145.38 559.69 μS/cm well, while Yaoundé, it 172.5 710.2 μS/cm. Dissolved oxygen 2.5 5.5 mg/l 3.9 5.1...
The health problems caused waterborne pathogens bacteria belonging to the Enterobacteriaceae family are aggravated by rise of antimicrobial resistant phenomenon. This has been identified as one biggest global challenges. present study aims make a comparative approach sensitivity/resistance antibiotics 4 Enterobacter cloacae, Citrobacter freundii, Salmonella typhi and Shigella sonnei isolated from wastewater, streams groundwater in Yaounde town (Cameroon, Central Africa). Bacteria were using...
The present study aims to assess the temporal variations of some biotic and abiotic biodegradation parameters 2 polymers (LDPE PP) by bacteria P. aeruginosa S. aureus at acidic, neutral, alkaline pH under mesophilic conditions. LDPE PP fragments were immersed in mineral solutions free carbon sources containing or cells. initial values (pHi) 5, 7 9. Incubation was carried out 28°C for 10, 20, 30, 40, 50 60 days. Results showed that during incubations, varies over time. In most cases,...
The present study assessed the abiotic factors of Moringa stenopetala (M. stenopetala) extracts against Staphyloccoccus aureus in aquatic microcosm. Bacterial survival was using colony forming unit (CFU) method on culture agar medium at different concentration levels (0.5 to 2 g/L). incubation duration varied from 3 24 hours, and temperatures were between 7°C 44°C. Phytochemical screening showed that most constituents obtained are alkaloids, flavonoids tannins. It observed increase extract...
As water resources in urban areas are becoming increasingly degraded, due large part to poor sanitation, a study has been was conducted examine the influence of physicochemical parameters and seasonal variation on distribution enterobacteria <i>Escherichia coli</i> <i>Salmonella </i>spp that have isolated from streams city Yaounde. Bi-monthly samples were collected nine rivers during 12 months (April 2010 March 2011). The isolation...
Species of the genus Proteus are cause several infections and represent one microorganisms commonly involved in hospital infections. These sometime difficult to treat because antibiotic resistance phenomenon, which represents greatest health challenges today. This study aimed at comparing diversity, abundance antimicrobial susceptibility species isolated from wastewater Mfoundi River Yaounde (Cameroon, Central Africa). The physicochemical parameters were measured using appropriate techniques...
This study aimed at assessing the MICs (Minimum Inhibitory Concentrations) and MBCs Bactericidal of methanolic extracts from 4 different parts (leaves, seeds, stem, roots) plant Moringa oleifera against bacteria E. coli S. aureus. Phytochemical profile each extract has been determined using LC/MS analyses. Microbial analyses were done 96-wells plate method. Results showed that four on plants contain heterosides glucosinolates. Iridoids found in leaves, stem roots. Flavonoids leaves stem....
Abstract In Cameroon, the dissemination of antibiotic-resistant bacteria in groundwater via hospital wastewater has not been sufficiently explored, despite growing volume lesstreated generated. This study aimed at assessing impact wastewaters on prevalence antimicrobial-resistant P. aeruginosa groundwater, two urban areas, Douala and Yaounde (Cameroon, Central Africa). each area, 12 well waters 2 effluents were sampled for water analysis. The wells then divided into groups. Those close to...
The main purpose of this investigation was to rank in the hierarchical order, some factors which may be predominant daily changes abundance Enterobacteriaceae wells, equatorial area Cameroon (Central Africa). Those included electrical conductivity, color, temperature, total suspended solids (TSS), pH, turbidity, CO2, NH4+ , BOD5, and cell concentration at initial moment. water temperature ranged between 19 20 °C. turbidity wells varied from 1.2 103 FTU. highest concentrations TSS 10 102...
Introduction: Foodborne resistant bacteria have become a challenge to food security. Milk and milk products are easy vectors of transmission foodborne pathogens, these being the main sources human infection by antimicrobial pathogens. The present study aimed at making comparative approach antibiotic sensitivity/resistance 3 bacterial strains (Escherichia coli, Salmonella spp. Brucella spp.) isolated from milk, drinking water green fodder consumed cows in West Cameroon region (Central...
