isolation and Susceptibility to Antimicrobial Agents of Salmonella paratyphi from Cheese in Khartoum (Sudan)

Abstract

This study was done to investigate the presence of Salmonellae in Sudanese white cheese at Khartoum State. Two hunderds cheese samples were purchased from restaur ants, retailers and shops, distributed in Khartoum and Omdurman. The isolated Salmonella paratyphi (6%) were equally identifed as paratyphi A and paratyphi B. The sensitivity to antibiotics for the isolated Salmonella spp. were also tried and multiple sensitivity was observed. Ciprofloxacin, Chloramphenicol and Ofloxacin were the most effective drugs against the tested isolates. The resistance was more frequent to Tetracycline, Gentamycin, Ampicillin, Penicillin and Co-trimoxazole. The present study concluded that Salmonella paratyphi A and Salmonella paratyphi B were isolated from cheese marketed in Khartoum State. Hence it is recommended that strict hygienic measurement and perodical survey and examinations should be done to ensure safety of food.
