Suid herpesvirus-1 (SHV-1), a DNA virus of the family Herpesviridae, causes a severe and fatal disease in a wide range of mammals. Here, we report the whole-genome sequence of an SHV-1 isolated in Italy in 2014 from the brain of a hunting dog that suffered from an acute and severe disease.

Introduction and objective: Klebsiella is an opportunistic pathogen that is an important cause of nosocomial infections. The prevalence of extended spectrum beta-lactamases (ESBLs)-producing strains and their resistance to betalactam antibiotics has had a daily increase. Because of the importance of these enzymes in Klebsiella pneumonia, this study was carried out to investigate it’s prevalence...

Klebsiella oxytoca strains are generally moderately resistant to amoxicillin and ticarcillin due to the activities of the chromosomally encoded OXY-1 and OXY-2 class A beta-lactamase families. These enzymes have the ability to hydrolyze not only penicillins but also cephalosporins, including cefuroxime, ceftriaxone, and aztreonam, and are inhibited by clavulanic acid. A Klebsiella oxytoca strai...

This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...

Escherichia coli remains as one of the most important bacteria causing infections in pediatrics and producing extended-spectrum beta-lactamases (ESBLs) making them resistant to beta-lactam antibiotics. In this study we aimed to genotype ESBL-producing E. coli isolates from pediatric patients for ESBL genes and determine their association with antimicrobial resistance. One hundred of the E. coli...

زمینه و اهداف: ظهور مقاومت باکتری ها نسبت به آنتی بیوتیک های بتالاکتام مربوط به پلاسمید کد کننده پنی سیلیناز است که به سرعت در بین نمونه های کلینیکی مربوط انتشار یافته است. پلاسمیدهای ESBL اجداد SHV-1, TEM-2, TEM-1 هستند که هم اکنون با جهش نقطه ای در آن باعث بروز بیش از 90 تیپ TEM و 25 تیپ SHV شده است. در همین راستا مطالعه ای جهت بررسی فراوانی انواع پلاسمیدهای ESBL در سویه های اشریشیاکلی و کلبس...

The growing frequency of antibiotic resistances is now a universal problem. Increasing resistance to new generations of β-lactam and quinolone antibiotics in multidrug-resistant Enterobacteriaceae isolates is considered an emergency health issue worldwide. The aim of this study was to evaluate plasmid-mediated quinolone resistance genes in ESBL-producing Escherichia coli isolated from urinary t...

Extended Spectrum Beta-Lactamases (ESBL) provide high level resistance to beta-lactam antibiotics among bacteria. In this study, previously described multidrug resistant bacteria from raw, treated, and municipal taps of DWDS from selected dams in southwestern Nigeria were assessed for the presence of ESBL resistance genes which include bla TEM, bla SHV, and bla CTX by PCR amplification. A total...

Among 120 Escherichia coli isolates from Thai patients, 37 and 9 isolates were extended-spectrum beta-lactamase (ESBL) and suspected ESBL producers respectively while 5 E. coli isolates from 120 Thai healthy adults were suspected ESBL producers. Integrase (intl1) gene was detected in 99% of the clinical and 87% of the non-clinical isolates. Among 37 ESBL producers, percent recovery of bla(TEM),...

OBJECTIVES The aim of this prospective study was to assess the extent of dissemination of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae at the hospital level in the United Arab Emirates (UAE). MATERIALS AND METHODS A total of 662 Escherichia coli and Klebsiellapneumoniae samples were collected from three UAE hospitals between January and December 2008. ESBL screening and c...
