“…Based on the results of this work, it is possible to conclude that groundwater can play an important role as a transmission vehicle of non-O1 V. cholerae and P. aeruginosa. Isaac-Marquez et al (1998) considered that the presence of non-O1 V. cholerae in water supplies might be responsible for a proportion of diarrheic diseases among population of the city of Campeche and the rural locality of Bécal (Mexico).…”

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%. Detectable non-O1 Vibrio cholerae was present in 81% of samples and the mean abundances ranged from 0 to 11100 MPN/100 mL. Significant correlations between fecal coliforms and streptococci and between fecal coliforms and non-O1 V. cholerae (p < 0.01) were found. Fecal coliforms can be used to detect the presence of non-O1 V. cholerae in this groundwater. These well waters were greatly mineralized, hard, salt with high concentrations of nitrogenous ions and major elements (Ca(2+), Na(+), Cl(-), SO(2-)(4) and K(+)). Most of chemical parameters were relatively steady with time except for calcium, ammonium, nitrites and organic matter which were seasonally influenced. The degree of correlation between chemical parameters and the abundances of isolated bacteria is heterogeneous. The concentrations of calcium and nitrites favored (p < 0.01) the abundance of fecal coliforms and streptococci, but reduced P. aeruginosa abundances. Calcium, salinity, chlorides, nitrites and nitrates tests can be used for screening in situ when the laboratory facilities are limited. This work is expected to assist local authorities in developing plans and actions to reduce the pollution to acceptable levels.

“…Isaac-Marquez et al (1998) considered that the presence of non-O1 V. cholerae in water supplies might be responsible for a proportion of diarrheic diseases among population of the city of Campeche and the rural locality of Becal (Mexico). Several reports have demonstrated that gastrointestinal and extra-intestinal infections caused by non-O1 V. cholerae are linked with contaminated water and other activities in aquatic environments, and this bacterium could therefore pose a problem for public health (WHO, 1993;Chakraborty et al, 1997).…”

“…A high prevalence of V. cholerae nonϭO1, non-O139 ampicillin (AMP)-resistant (Amp r ) isolates from both clinical and environmental origins was reported (3,7,10,19,29). To date, only three ␤-lactamases have been characterized in V. cholerae non-O1, non-O139 strains: CARB-2 (PSE-1), CARB-6, and CARB-7, which belong to the CARB family (Table 1).…”

The gene bla CARB-9 was located in the Vibrio cholerae super-integron, but in a different location relative to bla CARB-7 . CARB-9 (pI 5.2) conferred ␤-lactam MICs four to eight times lower than those conferred by CARB-7, differing at Ambler's positions V97I, L124F, and T228K. Comparison of the genetic environments of all reported bla CARB genes indicated that the CARB enzymes constitute a family of cassette-encoded ␤-lactamases.
