“…Moreover, 3 Klebsiella species were isolated; K. Pneumoniae (4%), K. oxytoca (6.6%), K. ozanae (11.3%), (Figure 1). Those species were also isolated by previous authors; Li et al, (2022) 2019) isolated K.pneumoniae (14.4%). Among the isolated coliforms spp., there were 24Citrobacter freundii isolates (16%), (Figure 1).…”

A total of 150 samples collected from freshly dead chickens were examined for Coliform bacteria. The results revealed isolation of 141 isolates (84 E. coli (56%), 6 Klebsiella pneumoniae (4%), 10 Klebsiella oxytoca (6.6%), 17 Klebsiella ozanae (11.3%), and 24 Citrobacter freundii (16%)). Strong biofilms on Congo red agar were produced by 37 E. coli isolates (44%), 3 Klebsiella pneumoniae (50%), 5 Klebsiella oxytoca (50%), 7 Klebsiella ozanae (41%) and 10 Citrobacter freundii (41%). Antimicrobial susceptibility test on strong biofilm producer isolates revealed that all isolates exhibited high resistance to Amoxicillin, Oxytetracycline and Erythromycin, Trimethoprim Sulfamethoxazole, while their sensitivity to gentamicin was high. Strong biofilm E. coli isolates were serotyped to O91:

“…The wide spread of ESBL-producing K. pneumoniae strains has been attributed to the overuse or misuse of antibiotics. ESBLs can hydrolyze different types of beta-lactam antibiotics, including cephalosporins and monobactams, and consequently, the treatment of infections caused by ESBL-producing strains has become a concerning issue [4,5]. Carbapenems are potent members of beta-lactams that are considered the last resort for the treatment of infections caused by multidrug-resistant bacteria [6].…”

Background: Carbapenem-resistant clinical isolates are extending rapidly, and in past recent years, carbapenem resistance has become an important health problem worldwide. This study aimed to investigate the carbapenem-resistance genes in extended-spectrum β-lactamase (ESBL) producing K. pneumoniae isolates. Methods: Seventy-five non-duplicate clinical K. pneumoniae strains were isolated from urine, blood, sputum, and wound samples. Antimicrobial susceptibility tests for 12 different antibiotics were performed using the disk diffusion method, followed by the determination of minimum inhibitory concentrations (MIC) of imipenem and meropenem. Phenotypic detection of ESBL and carbapenemase enzymes was performed by disk Disc Diffusion Synergy test (DDST) and modified Hodge test (MHT), respectively. Resistant isolates were further investigated for ESBL and carbapenemase genes by the PCR assay. Results: The highest and lowest resistance rates were observed against ampicillin (93.3%) and tigecycline (9.3%), respectively. Based on the results of phenotypic tests, 46.7% and 25.3% were positive for ESBL and carbapenemase enzymes, respectively. In addition, using the molecular method, the predominant ESBL-, and carbapenemase-associated genes were blaTEM (34.3%) and blaOXA-48 (57.8%), respectively. Conclusion: Based on the study, it has been found that K. pneumoniae strains produce significant rates of beta-lactamase enzymes, which is extremely alarming. As carbapenem resistance is an alarming public health issue, early detection of the isolates and effective infection control measures are necessary to prevent their further spreading.
