Extended Spectrum β-Lactamase-Mediated Resistance and Antibiogram of Pseudomonas aeruginosa Isolates from Patients Attending Two Public Hospitals in Khartoum, Sudan.

This study aimed to determine the antimicrobial susceptibility pattern and to determine the frequency of ESBL production among the P. aeruginosa isolates from patients at two public military hospitals in Khartoum, Sudan. A total of 34 isolates of P. aeruginosa obtained from patients with diabetic septic foot wounds were tested for their antibiotic sensitivity patterns. Resistance occurred most commonly to ceftazidime (35%), followed by ciprofloxacin (20.6%) and piperacillin (14.7%). We found that 17.6% of the P. aeruginosa isolates were ESBL producers, but all of these isolates were sensitive to meropenem. The chi-squared test showed a significant association between the ESBL production and antimicrobial resistance to amikacin, ceftazidime, and piperacillin. Our findings strengthen previous reports in which aminoglycosides (amikacin) and carbapenems (meropenem) were found to be highly effective against P. aeruginosa. Our findings highlight the need for effective surveillance and antibiogram-guided antibiotic prescription. PMID: 33163076 [PubMed]
