| determination of several potential virulence factors in non-o1 vibrio cholerae, pseudomonas aeruginosa, faecal coliforms and streptococci isolated from marrakesh groundwater. | the dynamic, hemolytic and hemagglutination activities and the antibiotic resistance of non-o1 vibrio cholerae, pseudomonas aeruginosa, faecal coliforms (fc) and faecal streptococci (fs), isolated by standard membrane filtration methods from suburban and rural groundwater supplies, were carried out. detectable non-o1 v. cholerae and p. aeruginosa was present in 81% and 88% of samples. the total occurrence of fc and fs during the period of study was 94%. the annual average densities of non-o1 v. ... | 2010 | 20371949 |
| environmental pollutions impacts on the bacteriological and physicochemical quality of suburban and rural groundwater supplies in marrakesh area (morocco). | this study scrutinized bacteriological and chemical quality of groundwater supplies of marrakesh (morocco) within a year. it assessed the influence of some chemical factors on fecal and opportunistic pathogenic bacterial communities. the annual average densities of fecal coliforms, fecal streptococci and pseudomonas aeruginosa were respectively: 1891 colony forming units (cfu)/100 ml, 1246 cfu/100 ml and 206 cfu/100 ml. the total occurrence of these bacteria during the period of study was 94%. d ... | 2008 | 18306049 |
| dynamics of non-o1 vibrio cholerae and fecal coliforms in experimental stabilization ponds in the arid region of marrakesh, morocco, and the effect of ph, temperature, and sunlight on their experimental survival. | we studied the spatial-temporal dynamics of non-o1 vibrio cholerae numbers at a stabilization pond treatment plant. this bacterium's seasonal dynamics were the inverse of those of fecal coliforms, with high levels in hot periods and low levels in cold periods. stabilization pond treatment did not significantly reduce non-o1 v. cholerae numbers between the system's inflow and outflow points. in contrast, fecal coliforms were reduced by 98.95% in hot periods and by 94.91% in cold periods. signific ... | 1995 | 7627909 |
