Abstract

Campylobacter spp were found in 15% out of one hundred samples of raw milk collected from Cairo & Giza area. None of 50 samples of each of white soft cheese and ice cream collected from Cairo & Giza area. Was found to contain Campylobacter spp. Out of the positive raw milk samples. 29 isolates of Campylobacter spp were identified as C.jejuni (62%), C.pyloric (28%) and C.fetus subsp venerealis (10%). At the same time, Acinetobacter spp were isolated from 30%of the raw milk samples, 20% of the white soft cheese samples and 20% of the ice cream samples. All isolates (121) of Acinetobacter spp were identified as, A.calcoaceticus subsp lwoffi. Heat inactivation treatments at 50, 55, 60, and 65c of 2 strains of C.jejuni and A-calcoaceticus subsp lwoffi proved to have no capability to survive the traditional pasteurization temperature, at the D65 valus for these pathogens were 4.5 and 1.2 sec., respectively.
