BACKGROUND Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is a major concern worldwide. It has been recently feared that the blaTEM-1 gene is, via blaTEM-135, evolving into an extended-spectrum β-lactamase (ESBL), which could degrade all cephalosporins including ceftriaxone. The aims of the present study were to characterize the blaTEM genes, types of β-lactamase plasmids, the degradat...

OBJECTIVES Sulbactam is well known to have clinically relevant intrinsic activity against Acinetobacter baumannii. Although secondary resistance to this drug has long been reported in acinetobacters, virtually nothing is known about its molecular basis. The aim of this study was to test the hypothesis that β-lactamase TEM-1 is responsible for sulbactam resistance in A. baumannii. METHODS Seve...

Objectives: This study aimed to determine the Enterobacteriaceae strains among patients who suffering diarrhea, phenotypic and genotypic characterization of ESBL-producing isolates in Jeddah, Saudi Arabia.
 Methods: Stool samples were collected cultured different strains, PCR was done for detect ESBLs genes antibiotic susceptibility against antibiotics done.
 Results: The total number...

Penicillinase-producing Neisseria gonorrhoeae (PPNG) carrying the blaTEM-135 gene is of particular concern, as it is considered a stepping stone toward resistance to extended-spectrum cephalosporins. Here, we sought to characterize plasmid types and the occurrence of the blaTEM-135 gene for N. gonorrhoeae clinical isolates from Australia. We found that blaTEM-135 was prevalent in Australian PPN...

Background The CTX-M family of extended-spectrum beta lactamase (ESBL) enzymes is comprised of over 60 blaCTX-M gene variants with the predominance of blaCTX-M-15 in many regions. In this report, we present the first description of blaCTX-M-28 in the United Arab Emirates. Methods Forty-five non-duplicate ESBL producing isolates identified in a secondary care facility in the United Arab Emirat...

Sir, The situation regarding antimicrobial resistance in bacteria from food-producing animals in Norway is, in an international perspective, favourable. The resistance frequencies are moderate and the situation has been stable since the start of the Norwegian monitoring programme in the veterinary sector (NORM-VET) (www. vetinst.no) in the year 2000. We report the first bacterial isolate of ani...

This study aims to determine the character and phylogenetics of β-lactamase Temoneira (blaTEM) gene in Escherichia coli isolated from reproductive tract Bali cattle with repeat breeder cases. was conducted June 2021 that used 16 female cases take their fluid using a plastic sheet gun. Isolation coli, Eosin Methylene Blue Agar identified by biochemical tests. Antibiotic susceptibility test on E....

ABSTRACT Objectives We determined the whole DNA sequences of plasmids carrying a rare extended-spectrum β-lactamase gene (blaTEM-61) to precisely understand spread resistance among nosocomial Serratia marcescens populations. Methods Twenty non-duplicate ceftazidime-resistant S. isolates (ceftazidime MICs, 32 >128 mg/L) collected over 1 year were pulsotyped and nucleotide blaTEM-61 its promoter ...

Kingella kingae is the prime pathogen of osteoarticular infections in young children in numerous countries (1–4). Although K. kingae is usually susceptible to antibiotics that are administered to children with skeletal system infections, -lactamase production has been sporadically detected in Iceland (5), the United States (6), Israel (7), and, more recently, in France (8). Using genotyping met...
