Acinetobacter baumannii (A. baumannii) is an important nosocomial pathogen in healthcare institutions. β-Lactamase-mediated resistance is the most common mechanism for carbapenem resistance in A. baumannii. The aim of this study was to determine the antibiotic resistance pattern, to detect OXA encoding genes, class A, bla PER-1, and to detect the presence of ISAba1. A total of 124 A. baumannii ...

ABSTRACT        Background and Objectives: Pseudomonas aeruginosa is the most frequent opportunistic pathogen isolated from the sputum of patients with cystic fibrosis (CF). Resistance to β -lactam antibiotics may arise from over expression of the naturally occurring AmpC cephalosporinases or acquired extended-spectrum β-lactamases (ESBL). The aim of...

BACKGROUND Cystic Fibrosis (CF) is an autosomal recessive genetic disorder in white populations caused by mutation in a gene that encodes Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein. Since frequent respiratory tract infections are the major problem in patients with CF, obligation to identify the causative bacteria and determining their antibiotic resistance pattern is cru...

Background and Objective: Biofilm formation plays a crucial role in wound infections and increases the bacteria resistance to treatment. The present study investigated the relationship between the biofilm formation, ESBL, AmpC, and KPC enzymes in Acinetobacter baumannii isolated from the wound specimens. Materials and Methods: Eighty- nine A. baumannii isolates were collected from wound specim...

conclusions a high prevalence of multiple β-lactamase production was observed among the ampc producers (60%), of which the majority co-produced ampc and mbl. the current study results showed correlation between β-lactamase production and the presence of antibiotic resistance genes in the isolates. results all isolates were multidrug resistant. ampc, esbl and mbl production were observed in 35 (...
