conclusions: this study highlighted the need to establish antimicrobial resistance surveillance networks for p. aeruginosa to determine the appropriate empirical treatment regimens. the high prevalence of multidrug resistance and production of esbls in p. aeruginosa isolates confirms the necessity of protocols considering these issues in the hospitals. results: the resistance against broad-spect...

BACKGROUND Extended-spectrum β-lactamases (ESBLs) are enzymes capable of hydrolyzing oxyimino-β-lactams and inducing resistance to third generation cephalosporins. The genes encoding ESBLs are widespread and generally located on highly transmissible resistance plasmids. We aimed to investigate the complement of ESBL genes in E. coli and Klebsiella pneumoniae causing nosocomial infections in hos...

Combining antibiotics with resistance reversing agents is a key strategy to overcome bacterial resistance. Upon screening antimicrobial activities of plants used in traditional medicine, we found that a leaf dichloromethane extract from the shea butter tree (Vitellaria paradoxa) had antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA) with further evidence of synerg...

Enterococci show intrinsic low resistance to a large number of antibiotics (β-lactams, lincosamines, aminoglycosides and trimetoprim-sulfametoxazol). In addition, Enterococci can acquire new resistance to antimicrobial agents. This can happen by mutation or acquisition of extrachromosomal DNA, as plasmids or transposons. Resistance to erythromycin, aminoglycosides and tetracycline are common. R...

The aim of this study was to isolate β-haemolytic Aeromonas hydrophila strains from live rainbow trouts (Oncorhynchus mykiss) destined for human consumption and to investigate their resistance to antimicrobial drugs. Sterile swab samples were collected from 52 rainbow trouts. Fifteen (28.8%) βhaemolytic Aeromonas strains were isolated from collected 52 swab samples. Through API 20 NE, 12 of the...

UNLABELLED Objective : The objective of the study was to observe the antimicrobial resistance of AmpC β-lactamase producing E. coli. METHODS Six hundred and seventy E. coli were isolated from 20,257 various pathological samples collected from The Children's Hospital and Institute of Child Health, Lahore, Pakistan. The isolates showed resistance to ceftazidime which were further examined for A...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...
