Background and Objective: Bacterial agents are the most common causes of urinary infection with Escherichia coli as the major causative organism. Accordingly, the current study aimed to determine the antibiotic resistance among Escherichia coli isolates from human urinary infection cases. Materials and Methods: The current experimental study was carried out on 50 specimens of positive cultures...
Background Resistant Shiga toxigenic Escherichia coli (STEC), is the most prevalent source of diarrhea in pediatrics. This study was conducted to investigate the antimicrobial resistance properties of STEC strains of diabetic and non-diabetic pediatrics with diarrhea. Materials and Methods: This was a case-control study conducted from December 2014 to September 2015 in an educational hospital, ...
Quinolone resistance is caused mainly by chromosomal mutations in gram negative bacteria. In 1998, plasmid-mediated resistance to quinolones in clinical isolates was first reported in a Klebsiella pneumoniae strain. Locus qnr (quinolone resistance) was responsible of the quinolone resistance in this plasmid. qnr codes a protein whose function is protect both DNA-girase and topoisomerase IV from...
The nucleotide sequence of a self-transmissible plasmid pVPH1 harboring bla(PER-1) from Vibrio parahaemolyticus was determined. pVPH1 was 183,730 bp in size and shared a backbone similar to pAQU1 and pAQU2, differing mainly in an ∼40-kb multidrug resistance (MDR) region. A complex class 1 integron was identified together with ISCR1 and bla(PER-1) (ISCR1-bla(PER-1)-gst-abct-qacEΔ1-sul1), which w...
Migratory birds may have a vital role in the spread of antimicrobial resistance across habitats and regions, but empirical data remain scarce. We investigated differences gut microbiome composition abundance antibiotic genes (ARGs) faeces from four migratory waterbirds wintering South-West Spain that differ their habitat use. The white stork Ciconia ciconia lesser black-backed gull Larus fuscus...
introduction: wastewater treatment plants are important hotspots for the spread of antibiotic resistance genes to the environment. the aim of this study identification of relevant antibiotic resistance genes in raw and final effluent of municipal wastewater treatment and also determination of effects of different wastewater treatment process on removal/reduction of these pollutants. materia...
Abstract Freshwater environments are vulnerable to emerging contaminants such as Antibiotic resistance genes (ARGs), and their occurrence is gaining more attention. However, the of ARGs along with potential pathogens less explored. The current study aimed evaluate abundance explore bacterial communities for presence in water samples collected from a tributary Yangtze River Nanjing. Twelve physi...
A Salmonella enterica serovar Corvallis strain was isolated from a wild bird in Germany. This strain carried the IncA/C2 pRH-1238 plasmid. Complete sequencing of the plasmid was performed, identifying the blaNDM-1, blaCMY-16, fosA3, sul1, sul2, strA, strB, aac(6')-Ib, aadA5, aphA6, tetA(A), mphA, floR, dfrA7, and merA genes, which confer clinically relevant resistance to most of the antimicrobi...
A conjugative IncL/M plasmid (pSEM) conferring resistance to gentamicin, amikacin, kanamycin, sulfonamides, and expanded-spectrum cephalosporins was found in pathogenic strains of Salmonella enterica serotype Typhimurium. Resistance to aminoglycosides was encoded by a sul1-type class 1 integron (In-t3). An extended-spectrum beta-lactamase gene, bla(SHV-5), was identified 3. 5 kb downstream of t...
