tailieunhanh - OprD protein profile of Pseudomonas Aeruginosa isolates resistant to Imipenem from patients in Khartoum state – Sudan

In Sudan, Pseudomonas aeruginosa is the most antibiotics resistant bacteria isolated among other bacterial strains of clinical impact. Carbapenems, such as imipenem are often used as last resort antibiotics for the treatment of multidrug-resistant Pseudomonas aeruginosa infection. The study was performed to evaluate the OprD porin protein profile among clinical isolates of Pseudomonas aeruginosa from urine samples. Fifty six clinical isolates of Pseudomonas aeruginosa were collected from different hospitals in Khartoum State. Imipenem susceptibility test was determined by the disk diffusion method. Carbapenems production was confirmed by Disk Enhancement Test (DET) and Combined disk test (CDT) Imipenem-Cloxacillin. The protein profile of the isolates was determined by SDS-poly acrylamide gel electrophoresis. Seventy two percent (72%) of the isolates were resistant to imepenim and about forty percent () of the imepenium resistant isolates were metalllobeta lacatamases producers. However, all resistant isolates showed OprD prion protein deficiency. This concludes the importance of OprD protein expression in increasing the sensitivity of Pseudomonas aeruginosa to antibiotics. | OprD protein profile of Pseudomonas Aeruginosa isolates resistant to Imipenem from patients in Khartoum state – Sudan
