[Study of the bacteriological quality of water used in the agro-food industry in the North of Morocco].

Introduction: Water is used predominantly in food manufacturing process. Northern morocco agro-food industries use different sources of water, but public water and wells water are the main sources of water used. This water can be the main source of possible food contaminations and alterations.

Enterotoxigenic coagulase positive Staphylococcus in milk and milk products, lben and jben, in northern Morocco.

Background: The aim of this research was to determine the prevalence of enterotoxin genes (sea-seo) in Coagulase Positive Staphylococcus (CPS) isolated from unpasteurized milk and milk products. These results were compared with the results obtained by using the detection kit SET-RPLA for the specific detection of staphylococcal enterotoxins (SEA-SED).

Methodology: Eighty-one samples of milk and milk products were analyzed for the presence of Staphylococcus strains.

Characterization of Staphylococcus species isolated from raw milk and milk products (lben and jben) in North Morocco.

Background: To investigate the incidence and antibiotic resistance of staphylococcal strains isolated from milk and milk products and to trace the ecological origin of the Staphylococcus aureus isolated.

Methodology: Eighty-one samples of raw milk, lben (whey) and jben (cheese) were analyzed for the presence of staphylococcal strains. Isolates were identified by Gram stains, tests for coagulase, the API staph system and the WalkAway 40/96, which also determines the antimicrobial susceptibility profiles.
