Background: Group B Streptococci (GBS) or Streptococcus agalactiae is one of the most common causes of sepsis and meningitis in neonates and of invasive diseases in pregnant women. It can also cause infectious disease among adults with underlying medical conditions like immunocompromised individuals. Polysaccharide capsule is an important virulence factor. Nine GBS serotypes (Ia, Ib, II to VI...

Introduction & Objective: Fluoroquinolones are essential antimicrobial agents used to treat UTIs. Clinical experiences have shown a high rate of antibiotic resistance among uropathogens. These resistance are usually the consequence of mutations involving genes encoding gyrA and parC. The aim of this study was to determine antimicrobial resistance pattern and the presence of mutations in regions...

    Background & Aims : After Vancomycin resistant Enterococci (VRE) was first detected in the mid 1980s, VRE spread rapidly worldwide and became one of the most serious problems in many hospitals specially in hospitalized patients. Among different enterococcal species Enterococcus feacalis and Enterococus faecium are the leading causes of life threatening infections. VanA/B/C genes are respons...

Background and Objective: AmpC-type beta-lactamases have been implicated in group C of Amber, which includes EBC, CIT, MOX, FOX, DHA, and ACC. The active presence of these plasmid genes in clinical isolates of P.aeruginosa has resulted in resistance to a wide range of antibiotics. Therefore, we aimed to determine the minimum inhibitory concentrations (MIC) of different antibiotic groups in clin...

 Background:  Acinetobacter baumannii is a non-fermentative gram-negative coccobacill that has high level of resistance to antimicrobial agents. Biofilm formation is an important feature of most clinical isolates of Acinetobacter spp, this led to higher resistance to antibiotics. The current study aimed to assess the ability of biofilm production and to determine the frequency of bap gene in cl...
