During this study, 109 faecal Escherichia coli samples isolated from 61 dogs and 48 humans were characterised according to phylogenetic group, extraintestinal virulence factors and antibiotic resistance. The isolates from dogs were predominantly distributed within phylogroup B1 (36%), while the majority of human strains belonged to phylogroup B2 (54%). The prevalence of cnf1, hlyA, papC and sfa...

conclusions high mdr isolates of e. coli were observed in this study. the significant association between class 1 integrons and resistance to ciprofloxacin, nalidixic acid, co-trimoxazole, amoxicillin, ceftazidime and tetracycline showed that class 1 integrons have an important role in resistance to these antibiotics in this region. results the highest rate of resistance was observed toward cep...

Colonization and infection by multidrug-resistant gram-negative bacilli (MDR GNB) in neonatal intensive care units (NICUs) are increasingly reported.We conducted a 5-year prospective cohort surveillance study in a tertiary NICU of the hospital "Paolo Giaccone," Palermo, Italy. Our objectives were to describe incidence and trends of MDR GNB colonization and the characteristics of the most preval...

The development of new strategic antimicrobial therapeutic approaches, such as drug repurposing, has become an urgent need. Previously, we reported that tamoxifen presents efficacy against multidrug-resistant (MDR) Acinetobacter baumannii, Pseudomonas aeruginosa, and Escherichia coli in experimental infection models by modulating innate immune system cell traffic. main objective this study was ...

The World Health Organization has rated multidrug-resistant (MDR) Pseudomonas aeruginosa as a critical threat to human health. In the present study, we performed a survey of intestinal colonization, and local and systemic immune responses following peroral association of secondary abiotic mice with either a clinical MDR P. aeruginosa or a commensal murine Escherichia coli isolate. Depletion of ...

Ceftolozane-tazobactam (C/T) is frequently used for infections caused by multidrug-resistant (MDR)-Enterobacterales isolates. Whole-genome sequencing (WGS, Illumina-Hiseq 4000/NovaSeq 6000, OGC, UK) was to study the population structure, resistome and virulome of C/T-susceptible -resistant MDR Escherichia spp. (n=30) Klebsiella (n=78) isolates, recovered from lower respiratory, intra-abdominal ...

Escherichia coli (E. coli) infections are the major health concern, as it causes infections in human mainly in urinary tract, ear, and wound infections. The present study evaluates the impact of biofield energy treatment on E. coli regarding antimicrobial sensitivity assay, biochemical study and biotype number. Four multidrug resistant (MDR) clinical lab isolates (LSs) of E. coli (LS 12, LS 13,...

INTRODUCTION Increase in extended-spectrum β-lactamases (ESBL) producing microbes in recent years has led to limitations of treatment options. This study aimed to assess the prevalence of ESBL producing E. coli and Klebsiella spp. at a tertiary hospital in Nepal. METHODS A total of 2209 non-repetitive mid-stream urine (MSU) samples were collected during the study period (March to September 20...

Escherichia coli populations originating from swine houses through constructed wetlands were analyzed for potential pathogens, antimicrobial susceptibility patterns, and genotypic diversity. Escherichia coli isolates (n = 493) were screened for the presence of the following virulence genes: stx1, stx2 and eae (Shiga toxin-producing E. coli [STEC]), heat-labile enterotoxin (LT) genes and heat st...

Multidrug-resistant (MDR) Gram-negative organisms are a burden on the global health care system. The Tigecycline Evaluation and Surveillance Trial (TEST) is an ongoing global study designed to monitor the in vitro activities of tigecycline and a panel of marketed antimicrobials against a range of clinically significant pathogens. In this study, in vitro data are presented for MDR Acinetobacter ...
