Isolation, characterization and thermal inact-ivation of campylobacter spp. from Egyptian raw milk

A total of 100 samples of raw milk, collected from different locations in Cairo and Giza Provinces, were examined for incidence of Campylobacter spp. Out of the 100 samples of raw milk, 15% were found to contain Campylobacter spp. The pathogenic types C. pyloric and C. fetus subsp. venerealis were isolated and identified in 6 and 2% of raw milk samples representing 5.3 and 2% of the total isolates, respectively. Thermal inactivation in terms of D and Z values were evaluated for two strains of C. jejuni
