conclusions the results indicate that the rates of esbls are high in urine e. coli and k. pneumoniae isolates from tehran hospitals. also this study indicates that the urine isolates from male patients are significantly more resistant than the female isolates. materials and methods a total of 190 e. coli and k. pneumoniae isolates were collected from patients’ urine samples in hospitals from te...
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 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: Mycoplasma pneumoniae is one of the major species of mycoplasmas which could contaminate cell cultures. Identification of M. pneuminae is significant because Mycoplasmas could contaminate and have unsuitable effect on the cell cultures. Rapid detection of these contaminations is so important and it could be significant role in preventing and controlling of contamination in cell cul...
Backgrounds & Objective: Mycoplasmas pneumoniae is responsible for more than 20% of community acquired pneumonia cases and also implicated in acute respiratory infections, such as sore throat, pharyngitis, rhinitis, and tracheobronchitis. Conventional assays for the detection of M. pneumoniae have their limitations, resulting in the need for more accurate diagnostic methods. Molecular methods, ...
Background: M. pneumoniae infection in children is usual and diagnosis of its neurologic complications for rapid treatment is very important. To compare the CSF- M. pneumoniae antibody level between febrile children with acute neurologic signs (Menigoencephalitis, Guillan Barre Syndrome (GBS), Transverse myelitis, Ataxia and so on) with unaffected ones.Methods: A cross sectional/ case control s...
Mycoplasma pneumoniae (M. pneumoniae) is an important pathogen of neonatal acquired pneumonia in newborns. Rapid and accurate diagnosis of M. pneumoniae infection is critical because timely antibiotic therapy can reduce drug overuse and prevent the development of bacterial resistance. Anti-M. pneumoniae immunoglobulin M (IgM) is an indicator of early infection that can persist for several month...
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In...
background and objectives: association between mycoplasma pneumoniae infection and increased risk for brain stroke has been well understood. hence, the value of serologic tests for assessing causative relationship between this infection and brain stroke seems to be high. the present study aimed to determine serum level of anti- mycoplasma pneumoniae antibodies in patients with brain stroke and ...
Attachment of radiolabeled M. pneumoniae to human WiDr cell culture monolayers was dependent on the WiDr cell density and the concentration of M. pneumoniae. Saturation of confluent monolayers grown on 5 mm coverslips was attained with only 40 micrograms of M. pneumoniae protein. Preincubating the WiDr monolayers with unlabeled M. pneumoniae or with a protein-rich extract prepared from M. pneum...
