Background: ESBLs are enzymes which are capable of hydrolysing penicillins, broad-spectrum cephalosporins and monobactams. They are generally derived from TEM and SHV-type enzymes. Materials and methods: We investigated the presence of TEM, SHV, CTX-M, OXA and IBC beta-lactamase genes by PCR in 300 E. coli, 130 Klebsiella spp., 100 P. aeruginosa ve 23 Enterobacter spp. isolated from various cli...

Acinetobacter baumannii is a ubiquitous pathogen that has emerged as a major cause of healthcare-associated infections at Ladoke Akintola University Teaching Hospital. Isolates were assayed according to standard protocol. The isolates were subjected to molecular techniques to detect blaOXA, blaTEM, blaCTX-M, and blaSHV genes in strains of the A. baumannii isolates. The prevalence of A. baumanni...

A total of 310 Salmonella isolates were isolated from 6 broiler farms in Eastern China, serotyped according to the Kauffmann-White classification. All isolates were examined for susceptibility to 17 commonly used antimicrobial agents, representative isolates were examined for resistance genes and class I integrons using PCR technology. Clonality was determined by pulsed-field gel electrophoresi...

AIM The present investigation was conducted to isolate and characterize Salmonella Gallinarum from an outbreak of fowl typhoid in layer birds. MATERIALS AND METHODS Clinically ill and dead layer birds from an outbreak were investigated. History, clinical signs, and postmortem lesions were suggestive of fowl typhoid. Postmortem samples including heart blood, intestinal contents, pieces of ovar...

background: resistance to contemporary broad-spectrum b-lactam antibiotics mediated by extended-spectrum b-lactamases (esbls) is increasing worldwide. klebsiella pneumoniae , an important cause of nosocomial and community acquired urinary tract infections has rapidly become the most common esbl producing organism. we examined esbl production in urinary isolates of k. pneumoniae in relation to t...

Introduction and Aim: Carbapenem Resistant Enterobacteriaceae (CRE) have emerged at an alarming rate. Multi locus sequence typing (MLST) is important parameter for identifying drug resistant organisms. The present study was carried out elucidating the mechanisms of CRE MLSTs associated with CRE. Materials Methods: (n=14) were obtained from various clinical samples subjected to Rapidec Carba NP ...

conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...

objective(s) extensive use of quinolones has been associated with raising level of resistance. in the current, we focused on assessing the prevalence of escherichia coli resistance to quinolones and frequency of qnra, qnrb and qnrs in non esbls (extended spectrum beta-lactamases) and esbls producing e. coli with blashv and blatem. materials and methods one hundred and fifty e. coli isolates wer...

background emerging antibacterial resistance rates and extended-spectrum-β-lactamase producing escherichia coli recovered from urinary tract infections (uti) is an increasing problem in different regions, limiting therapeutic options. objectives the aim of this study was the detection of blatem, blashv and blactx-m genes among escherichia coli strains causing urinary tract infection in children...
