On SA agar plates using also surface plating technique, Aeromonasspecies could be detected in 34 (45.3%), 13 (26%), 35 (70%), 36 (72%) and 30 (40%) of the examined raw milk, Damietta cheese, kareish cheese, cooking butter and ice cream samples with average counts of2.8

Aerotnonasspecies recovered on TSA agar plates could be differentiated into A. hydrophilawhich could detected in 20 (26.7%), 7 (14%), 15 (30%),23 (46%), and 13 (17.3%), A. caviaecould be detected in 10 (13.3%), 10 (20%),14 (28%),13 (26%) and 17 (22.7%), whileA. sobriacould be detected in 5 (6.7%), 1 (2~j), 9 (18%), 4 (8%) and 5 (6.7%) of the examined raw milk, Damietta cheese, kareish cheese, cooking butter. ice cream samples, respectively.
