ABSTRACT

Fifty samples of raw milk were randomly collected from fayoum markets for bacteriological examination. The average counts of enterococci, coliform group, staphylococci, clostridium, aerobic spreformers and Bacillus cereus were, 80 * 10[4], 12 * 10[3], 17 * 10[2], 3.5 * 10,20 * 10[2] and 3.5 * 10 CFU/ ml respectively. All samples were free from salmonella. In addition psychrotrophic, mesophilic and lactic acid bacteria counts were counted in all the samples. On the other hand, 94.5%, 94.4%, 100% and 11.8% of indentified isolates were Streptococcus faecalis, enteropathogenic Escherichia coli, Bacillus cereus and enterotoxigenic Staphylococcus aureus respectively
