| Abstract | ||||
| The present investigation was conducted, to identify and characterize bacterial communities including starter bacteria as well as pathogenic ones, on some local cheese products produced in Saudi Arabia in order to ensure human health. The isolated strains were characterized by phenotypic, physiological and biochemical methods, including API 20 Strep. kit. The results showed that high counts of lactic acid bacteria (LAB) were found. The dominated species found were Streptococcus salivaius ssp. thermophilic (50%), Leuconostc spp. (24%), Lactococcus lactic ssp. lactic (4%), Streptococcus mitis (2%), Enterococcus faecium (12%), Streptococcus acidominimus (4%), and Enterococcus durans (4%). The results obtained demonstrated that the pathogenic bacteria in five examined products are Enterobacter Cloacae, Enterococcus faealis, Pseudomonas spp., staphylococcus aureus, Klebsilla sp., Bacillus spp., and Corynebacterium (Diptheroid) spp. | ||||
