OBJECTIVES The objective of this study was to examine Klebsiella oxytoca clonal and phylogenetic diversity, based on an international collection of carriage isolates non-susceptible to expanded-spectrum cephalosporins (ESCs). METHODS The study material comprised 68 rectal carriage K. oxytoca isolates non-susceptible to ESCs recovered in 2008-11 from patients in 14 hospitals across Europe and ...

OBJECTIVES We characterized mechanisms of resistance to oxyimino-cephalosporins in Escherichia coli isolated from raw chicken meat imported into the UK from South America, to ascertain whether this foodstuff contributes to the dissemination in the UK of extended-spectrum β-lactamase (ESBL)-producing E. coli belonging to the international uropathogenic ST131 clone. METHODS Sampling and collect...

BACKGROUND AND OBJECTIVE AmpC β lactamases are one of the important causes of drug resistance in gram negative bacteria. Failure to detect these enzymes in the laboratory has contributed to therapeutic failures but there are till date no standard guideline available. This study was therefore undertaken to evaluate three phenotypic laboratory tests and the inhibitors used in two of the tests to ...

زمینه و اهداف: مواد ضدمیکروبی بتالاکتام در حال حاضر رایج ترین درمان برای عفونت های باکتریایی می باشند. استفاده از آنها منجر به بروز مقاومت باکتری های گرم منفی در برابر آنتی بیوتیک های بتالاکتام در سراسر جهان می شود. آنزیم های بتالاکتاماز وسیع الطیف (ESBLs) آنتی بیوتیک های بتالاکتام را هیدرولیز و غیرفعال می کنند. آنزیم های AmpC در کلاس C طبقه بندی ESBLs جای دارند. آنزیم های AmpC تیپیک که سفالوس...

Background and Objective: There is a growing concern regarding the lack of new antibiotics, especially for multidrug-resistant bacteria that produce Extended Spectrum β-Lactamases (ESBLs). The present study aims to assess the prevalence of bacteria producing ESBLs, their antimicrobial resistance pattern, and its main determinants among hospitalized patients.Method...

To evaluate the water compartment antibiotic-resistance contamination rates, 11 wells, five streams, and four treatment plants located in the Oltrepò Pavese area were screened for the presence of third generation cephalosporins resistant Gram-negative bacteria. Enterobacteriaceae were also characterized for the Extended-Spectrum-β-Lactamases (ESBLs), carbapenemases, and mcr-1 genes presence. Fr...

چکیده    مقاومت ضدمیکروبی ایجاد شده به­واسطه تولید آنزیم­های بتالاکتاماز وسیع­الطیف (ESBLs) در اشریشیا کلی یک تهدید اساسی در کلی­باسیلوزیس ماکیان محسوب می­شود. مطالعه حاضر به شناسایی ژن­های blaTEM، blaSHVو blaOXAدر جدایه­های اشریشیا کلی به­دست آمده از کلی­باسیلوزیس طیور با استفاده از روش MPCR می­پردازد. در مجموع، 60 جدایه اشریشیا کلیاز طیور استان کرمان به­دست آمد. DNA سلولی با استفاده از کیت D...

Background & Aims: Considering the importance of drug resistance among pathogenic bacteria and their treatment problems, this study aimed to determine the prevalence of extended-spectrum beta-lactamases (ESBLs), including TEM, SHV, and OXA genes among the isolated Escherichia coli and Klebsiella pneumoniae obtained from urine specimens of kidney transplant patients. Materials & Methods: The ba...

Salmonella spp. is one of the most important food-borne pathogens causing digestive tract and invasive infections in both humans and animals. Extended-spectrum β-lactamases (ESBLs) especially the CTX-M-type ESBLs are increasingly being reported worldwide and in China. These studies seldom focused on Salmonella isolates from food-producing animals. The aim of this study was to characterize the a...
