Background: This study aimed to describe the association between age groups and antimicrobial susceptibility patterns, also integron presence in Escherichia coli and Klebsiella pneumoniae  isolates from Tabriz, Iran. Materials and methods: 140 isolates of E. coli and 150 isolates of K. pneumoniae, both comprising the same number of children and adult isolates were examined for susceptibil...

Background: CTX-M-type extended-spectrum β-lactamases (ESBLs) are the most prevalent ESBLs in bacterial members of Enterobacteriaceae family including Klebsiella pneumoniae. The global spread of CTX-M-producing K. pneumoniae is a major concern in most countries including Iran. The aim of this meta-analysis was to determine the relative frequency (RF) of blaCTX-M gene among ESBLs-producing K. pn...

Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...

The present study assessed the diagnostic usefulness of a multiplex PCR (mPCR) for Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae and Chlamydophila pneumoniae applied to bronchoalveolar lavage (BAL). Fibreoptic bronchoscopy was performed on 156 hospitalised adult patients with lower respiratory tract infection (LRTI) and 36 controls. BAL fluid was analysed with bacteria...

background and objective: the production of carbapenemases especially klebsiella pneumoniae carbapenemase (kpc) is the most important mechanism of enzymatic resistance in isolated enterobacteriaceae such as k. pneumoniae. the purpose of this study was detected of the carbapenemase producer k. pneumoniae strains with phenotypic and genotypic methods. method: out of 800 strains, 270 k. pneumoniae...

OBJECTIVE To study atheromas, Mycoplasma pneumoniae (M. pneumoniae), and Chlamydia pneumoniae (C. pneumoniae). METHODS C. pneumoniae was studied with immunohistochemistry and M. pneumoniae with in situ hybridization (ISH), in segments of coronary arteries (SCA) as follows: group A - thrombosed ruptured plaques (TRP) of 23 patients who died due to acute myocardial infarction (AMI); group B - 2...

background and objectives: chronic infection in childhood is a leading cause of adeno-tonsillectomy . the aim of this study was to determine the role of m. pneumoniae in children with rhino sinusitis and adenoid hypertrophy. materials and methods: this case - control study was carried out in the pediatric and ent wards of hazrat rasul hospital, tehran, iran (2007-2009). in this trial, we invest...

Background and Objective: The production of carbapenemases especially Klebsiella pneumoniae carbapenemase (KPC) is the most important mechanism of enzymatic resistance in isolated Enterobacteriaceae such as K. pneumoniae. The purpose of this study was detected of the carbapenemase producer K. pneumoniae strains with phenotypic and genotypic ...

BACKGROUND The incidence of severe acute respiratory tract infections in children caused by Mycoplasma pneumoniae (syn. Schizoplasma pneumoniae) and Chlamydophila pneumoniae (formerly Chlamydia pneumoniae) varies greatly from year to year and place to place around the world. This study investigated the epidemiology of M. pneumoniae and C. pneumoniae infections among children hospitalized with a...
