Background and Objective: Klebsiella pneumoniae is one of the most important causative agents both in form of hospital acquired and community-acquired infections. This bacterium is one of the most prevalent pathogens that is isolated from hospitals and is associated with high mortality rates. The uprising trend of multi drug resistance among Klebsiella pneumoniae has limited the treatment optio...

Background and Objective: The production of Extended Spectrum Beta Lactamases (ESBLs) by Escherichia coli is the main cause of resistance to Cephalosporins. In the past decade, CTX-M enzymes have become the most prevalent ESBLs in Europe, Canada, and Asia. In this study, the frequency of ESBL-producing E.coli and molecular detection of the CTX-M-I group was investigated. Materials and Methods: ...

Background & Objectives:Extended-spectrum-B-lactamase (ESBL)-producing strains of Klebsiella Pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. This study was performed to determine the prevalence of ESBL-producing K. Pneumonia and to evaluate the frequency of TE...

Objective(s) Different types of extended spectrum beta-lactamases (ESBLs) are encountered in the clinical settings worldwide. There are a few studies regarding the prevalence of ESBL genes among Klebsiella pneumoniae isolates at Tehran especially those of blaPER and blaCTX. The aim of this study was to determine the prevalence of blaSHV, blaTEM ,blaPER and blaCTX genes among clinical K. pneumo...

The objective of this study was to characterize the gene cassettes of class 1 integrons and antimicrobial resistance among CTX-M-3-producing Serratia marcescens isolates from different specimens in southern Taiwan. One hundred and twenty-two isolates (70.5%) of 173 CTX-M-3-producing S. marcescens isolates were positive for class 1 integrons, including 53.3% of blood isolates, 94.1% of urine iso...

Background and Aim: The variety of sweets along with significant difference level of hygiene in the production, supplies and high potential contamination of sweets ingredients with Escherichia coli, led to investigate the frequency of broad-spectrum beta lactamase strains of E. coli in sweets and determine the presence of SHV, TEM and CTX-M genes. Material and methods: In this descriptive cros...

 Introduction: A Klebsiella pneumoniae bacterium, which is the most important species of the Klebsiella genus, mainly causes hospital infections. Moreover, it has a high resistance to most of the available antibiotics, which has caused concern among doctors all over the world. Therefore, the amount of antibiotic resistance and the effect of these antibiotics on Klebsiella pneumoniae isolates pr...
