چکیده

This study aims to evaluate the positive predictive value (PPV) and the negative predictive value (NPV) of Vitek2 in detecting extended-spectrum beta-lactamase (ESBL) phenotypes when compared to a manual confirmatory test as gold standard. A sample of Escherichia coli, Klebsiella spp and Proteus mirabilis isolates were collected by 5 laboratories in the Emilia-Romagna Region (Italy). Vitek2 appears to be an accurate tool to detect ESBL phenotypes of E. coli isolates; some concern remains about its performance with the other bacterial species, especially P. mirabilis.

Frequency of extended spectrum beta lactamase producer P. aeruginosa strains isolated from burned patients of Motahari hospital, Teharan, Iran

Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...

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...

Phenotypic and genotypic studies of extended spectrum beta-lactamase (ESBL) resistance among Salmonella isolates from poultry sources in Iran

BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...

Abstract Background and Objective: In the past, most strains of E. coli were susceptible to a wide range of antimicrobial agents, but this situation is now changed by indiscriminate use of antibiotics. Ceftriaxone and Ceftazidime are the most current antibiotics used for Enterobacteriaceae infections in hospitals. The aim of this study was to determine antimicrobial resistance of Escherichia co...
