Prevalence and pathogenesis of extended-spectrum beta-lactamase producing Escherichia coli causing urinary tract infection in hospitalized patients

Antibiotic Resistance Pattern of Different Escherichia coli Phylogenetic Groups Isolated from Human Urinary Tract Infection and Avian Colibacillosis

“…In group B1 of APEC isolates, all of them were resistant to tetracycline, erythromycin, nalidixic acid, cefixime, cephalexin, penicillin, amoxicillin, and ampicillin. Because of extensive use of antibiotics to promote weight gain and for prophylaxis purposes, this high level of resistance was expected in commensal organisms (group A and B1 of APEC isolates) [22]. …”

“…However, in group D of APEC isolates, all of them were resistant to erythromycin, ciprofloxacin, nalidixic acid, cephalexin, amoxicillin, ampicillin, and penicillin. This fact could be due to the high level of prevalence [15, 23, 24], virulence [1, 2, 15, 25], resistance [2, 22], and plasmid-mediated resistance gene transfer in these isolates (groups B2 and D).…”

Empirical therapies among adults hospitalized for community-acquired upper urinary tract infections: A decision-tree analysis of mortality, costs, and resistance

“…Sensitivity analyses were conducted within this range. [13][14][15][16][17][18][19][20] The case-base analysis model used a fixed prevalence of ESBL-positive E coli isolates of 5%, which corresponds to the weighted rates of ESBL-positive E coli isolates collected from patients suffering from UTI.…”

Invasion and translocation of uropathogenic Escherichia coli isolated from urosepsis and patients with community-acquired urinary tract infection

“…These strains had been typed using a combination of PhP typing and the RAPD-PCR and phylogenetic grouping in previous studies [25,27,28] and had been grouped as common types (CT; types with more than one isolate) and single types (ST, types with only one isolate). Overall, 75 CTs comprising 282 isolates and 118 STs were identified across all groups.…”
