Molecular detection, quantification and characterization of extended-spectrum β-lactamase (ESBL)- and AmpC-encoding genes in a cucumber agroecosystem
… antibiotic resistant bacteria (ARB) (including extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae) in fresh produce, is therefore imperative owing to the global push towards healthier diets with a focus on raw food due to its high nutritious value. In this context, bacteria that …

Klebsiella pneumoniae bloodstream infections in hospitalised children at Red Cross War Memorial Children's Hospital : 2006 - 2011
… infection (KPBSI), 339 (83%) were presumed extended-spectrum β-lactamase (ESBL) producing isolates. The median age (interquartile range, IQR) was 5.0 (2-16) months, 212 (51.7%) were male, 82 (20%) were HIV-infected, and 241 (58.8%) were moderately or severely underweight. The infection was …

Using wildlife to biomonitor for antimicrobial resistance in the Scottish environment
… gen. cephalosporins, and genes associates with extended spectrum β-lactamase resistance were detected. We also investigated the use of freshwater invertebrates as a biomonitoring tool. We utilised invertebrate samples to obtain reference data on the AMR of E. coli present in the freshwater …

ENABLING RAPID PHENOTYPIC DETECTION OF CEPHALOSPORIN RESISTANCE BEYOND THE CENTRAL LABORATORY
… resistance activity in bacteria expressing extended-spectrum β-lactamase (ESBL) enzymes, one of the most prolific resistance strategies used by superbugs. Next, we describe methods of integrating these detection molecules into practical testing methods, and detail the engineering of simpler …

A ten-year review of ESBL and non-ESBL Escherichia Coli Bloodstream infections among children at a tertiary referral hospital in South Africa
… including incidence risk, risk factors for extended spectrum β-lactamase (ESBL)- producing E. coli BSI, antibiotic susceptibility of the bacterial isolates and outcome including risk factors for severe disease. Results: There were 583 new E. coli BSI episodes among 217,483 admissions, an …

Outer Membrane Porin Regulation among Different Sequence Types of Escherichia coli Clinical Isolates
… susceptibility when the organism produces an extended-spectrum β-lactamase or plasmid-encoded AmpC. Altering the production of porins could impact the fitness, and therefore the success of ST131 E. coli. The experiments described in this dissertation sought to identify differences in the …

Diversity of acinetobacter baumannii isolates from Egypt
… Resistance to Ceftazidime was mediated by Extended-spectrum β-lactamase (ESBL) genes belonging to PER-like group: blaPER-1, blaPER-7 and the first report of blaPER-3 gene and its genetic environment in A. baumannii. In conclusion, this study shows the diversity exhibited by A. baumannii in …

PREVALENCE, LONGITUDINAL DYNAMICS, AND FACTORS ASSOCIATED WITH THE FAECAL SHEDDING OF EXTENDED-SPECTRUM Β-LACTAMASE-PRODUCING BACTERIA IN ITALIAN NEONATAL DAIRY CALVES
… Among the most resistant bacteria of concern, extended-spectrum β-lactamase (ESBL)-producing Enterobacterales are particularly relevant because they limit the efficacy of critically important β-lactam antimicrobials and can disseminate across the animal–human–environment interface. In dairy …

Investigation of Biofilm Development by Antibiotic Resistant Urinary Tract Infection Pathogens and Evaluation of the Antimicrobial Activity of Natural Products on Carbapenem-Resistant Escherichia coli IMP and Klebsiella pneumoniae NDM-1.
Extended-spectrum β-lactamase (ESβL) producing bacteria, including Carbapenem-Resistant Enterobacteriaceae (CRE), are becoming increasingly prevalent worldwide. Understanding the biology behind the ability of these pathogens to form biofilms is crucial to the treatment of the infections caused by …

EXTENDED-SPECTRUM Β-LACTAMASE-, AMPC- AND CARBAPENEMASE-PRODUCING BACTERIA IN DOGS AND CATS
La resistenza antimicrobica (AMR) rappresenta una delle minacce più critiche per la salute globale, che compromette l'efficacia degli antibiotici e minaccia la salute sia umana che animale. L'aumento di batteri multiresistenti (MDR) mina l'efficacia dei trattamenti per le infezioni negli esseri …
