Occurance of Enterobacteriaceae in Sudanese White Cheese in Restaurants of Khartoum State (Sudan)

E.M. El Zubeir Ibtisam, B.O. El Zubeir Sanna and O. Yagoub Sanaa
In the present survey a total of thirty one Enterobacteriaceae were found in twenty samples (66.7%) out of thirty samples of Sudanese white cheese. The total isolated Enterobacteriaceae include Citrobacter freundii (14, 46.7%), E. coli (6, 20%), Enterobacter aerogenes (2, 6.6%), Pseudomonas aeruginosa (1, 3%), P. mirabilis (5, 16.7%) and Sallmonella ssp. (3, 10%). The restaurants located at Khartoum North revealed 4 (44.4%), 1 (11.11%), 1 (11.11%) and 2 (22.2%) isolate of C. freundii, E. coli, Pseudomonas aeruginosa and P. mirabilis, respectively. Similarly the isolates from restaurants located in Khartoum were 5 (55.5%) isolates of C. freundii, 3 (33.3%) isolates of E. coli, 2 (22.22%) isolates of Enterobacter aerogenes, 1 (11.11%) isolate of P. mirabilis and 2 (22.2%) isolates of Salmonella paratyphi. The restaurants located in Omdurman revealed 5 (41.7%) isolates of C. freundii, 2 (16.7%) isolates of E. coli, 2 (16.7%) isolates of P. mirabilis and 1 (8.3%) isolate of Salmonella typhi. The mean, minimum and maximum counts of Enterobacteriaceae were found to be 2 x 104±3.1 x 104, 0 and 8 x 104; 2.6 x 104±1.8 x 104, 0 and 5 x 104 and 1.33 x 104±1.96 x 104, 0 and 6.0 x 104, respectively, for the cheese samples collected from restaurants of Khartoum North, Khartoum and Omdurman. The total bacterial counts were found to be higher in samples with higher count of Enterobacteriaceae and this was mainly noticed in restaurants at Khartoum, which revealed 5.6 x 108±3.7 x 108, 2 x 107 and 9 x 108, respectively. However the bacterial count were found to be 2.9 x 108±2.4 x 108, 2 x 107 and 6 x 108 and 2.7 x 108±2.1 x 108, 2 x 107 and 7 x 108 in Khartoum north and Omdurman restaurants, respectively. There was a significant difference (p<0.05) for the total bacterial count between Khartoum and the other studied locations, as the the samples collected from Khartoum revealed the higher counts compared to other two areas. However non significant variation were recorded for Enterobacteriaceae counts.
