The dissemination of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) from food-producing animals to the surrounding environment has attracted much attention. To determine the emissions of ESBL-producing E. coli from pig farms to the surrounding environment, fecal and environmental samples from six pig farms were collected. In total, 119 ESBL-producing E. coli were isol...
Since 2000, Escherichia coli producing CTX-M enzymes (especially CTX-M-15) have emerged worldwide as important causes of community-onset urinary tract and blood stream infections due to extended-spectrum β-lactamase (ESBL) producing bacteria. Studies suggest that the sudden worldwide increase of CTX-M-15-producing E. coli is mostly due to a single clone named ST131 and that foreign travel to hi...
background : the emergence and increase in the incidence of extended-spectrum beta lactamase (esbl) producing escherichia coli has become an emerging challenge especially in hospitalized patients with uti. the aim of the present study was to survey the frequency of bla ctx-m genotype in esbl producing e. coli isolated from hospitalized patients with uti and determination of their antibiotic res...
2 3 Background: A high rate of resistance to 3 rd generation cephalosporins among Enterobacteriaceae 4 isolates from Egypt has been previously reported. This study aims to characterize the resistance 5 mechanism (s) to extended spectrum cephalosporins among resistant clinical isolates at a medical 6 institute in Cairo, Egypt. 7 Methods: Nonconsecutive Klebsiella pneumoniae (Kp), Enterobacter cl...
A subset of the study population from a cross-sectional study of carriership of ESBL/pAmpC-producing E. coli (ESBL-E) in the general population was followed up by five successive samples over an approximate half year period, leading to six samples in 333 persons. Fecal samples were cultured and analyzed for the presence of E. coli types as characterized by MLST, and ESBL/pAmpC genes were analys...
OBJECTIVES Recently, a CTX-M-15 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli O25b-ST131 clone, belonging to the B2 phylogenetic group and with a high virulence potential, has been reported all over the world, representing a major public health problem. The present study was carried out to develop a rapid and simple detection assay that identifies members of this clone. M...
Carbapenem-resistant Gram-negative bacilli resulting from β-lactamases have been reported to be an important cause of nosocomial infections and are a critical therapeutic problem worldwide. This study aimed to describe the prevalence of imipenem-resistant Gram-negative bacilli isolates and detection of bla VIM, bla TEM, bla SHV, bla CTX-M-1, and bla CTX-M-9 genes in these clinical isolates in E...
مقدمه: بتالاکتامازهای با طیف گسترده ( esbls ) بهعنوان مهمترین شاخص مقاومت به آنتی بیوتیکها در بین انتروباکتریاسهها در سراسر جهان هستند. در طول دهه گذشته، انواع ctx - m از esbl شیوع بالایی داشته و بیشتر در ارتباط با مسببین مهم عفونت ناحیه ادراری ( uti ) هستند. هدف از این مطالعه بررسی الگوی مقاومت به آنتی بیوتیک و فراوانی بتالاکتامازهای ctx - m در بین جدایههای e. coli با مقاومت چندگانه دارو...
aim : the aims of this study were to determine the phylogenetic groups and investigate phenotypic and genotypic of esbl and mbl-producing e . coli isolates from patients with diarrhea in kerman, southeast of iran. background : escherichia coli is detected as a significant cause of sporadic and outbreaks of diarrhea. the emergence of extended-spectrum ?-lactamases (esbls) and metallo-?-lactamas...
