The results of the keeping quality tests revealed that 6 % outof examined raw milk samples were precepitated with alcohol, while twosamples were clotted-on-boiling.Concerning titratable acidity the obtained results revealed that themean acidity percent in raw milk, Damietta and kariesh cheese sampleswere 0.14 ± 0.003,0.82 ± 0.05 and 0.99 ± 0.04, with a minimum of 0.10,0.34 and 0.76 and a maximum of 0.22, lA and lA, respectively.The bacteriological examination showed that the mean proteolyticcount / ml or gram in examined raw milk, Damietta and kariesh cheesesamples were 5.3 x 106 ± 2.05 x 106,3.81 x 106± 1.96 x l06and 2.84 x1012 ± 1.67 x 1012, respectively.Pseudomonas spp., Enterobacteriaceae, Acentiobacter spp., Gram-positive spp., Alcaligens spp., Achromobacter spp., Aeromonoas spp.,Flavobacterium spp., Vibrio, Chromobacterium spp., could be detected inthe examined samples at varying percentages.
