Background: Reduced susceptibility of Clostridium difficile to antibiotics is problematic in clinical settings. There is new evidence indicating the cotransfer of toxin-encoding genes and conjugative transposons encoding resistance to antibiotics among different C. difficile strains. To analyze this association, in the current study, we evaluated the frequency of toxigenic C. difficile among th...
Strains of Pseudomonas that produce antimicrobial metabolites and control soilborne plant diseases have often been isolated from soils defined as disease-suppressive, i.e., soils, in which specific plant pathogens are present, but plants show no or reduced disease symptoms. Moreover, it is assumed that pseudomonads producing antimicrobial compounds such as 2,4-diacetylphloroglucinol (DAPG) or p...
Nonhuman primates are commonly used for cognitive neuroscience research and often surgically implanted with cephalic recording chambers for electrophysiological recording. Aerobic bacterial cultures from 25 macaques identified 72 bacterial isolates, including 15 Enterococcus faecalis isolates. The E. faecalis isolates displayed multi-drug resistant phenotypes, with resistance to ciprofloxacin, ...

ABSTRACT Background and Objectives: Acinetobacter species are responsible for a wide range of clinical complications in hospitalized patients. Antimicrobial treatment of clinical strains of Acinetobacter baumannii may be compromised due to multiple-drug resistance to b-lactams. Aim of this study was to determine antibiotic resistance patterns an...
objectives we investigated the potential relationships between biofilm formation and prevalence of virulence genes (asa1, esp, cyla, and gele/spre), and antimicrobial resistance genes (aac (6’)/aph (2”) in enterococcus faecalis isolated from patients with urinary tract infection. patients and methods in this survey 95 e. faecalis isolates from patients with urinary tract infections staying at s...
Contamination of surface waters in developing countries is a great concern. Treated and untreated wastewaters have been discharged into rivers and streams, leading to possible waterborne infection outbreaks and may represent a significant dissemination mechanism of antibiotic resistance genes. In this study, the water quality of San Pedro River, the main river and pluvial collector of the Aguas...
Background & aim: About 40% of women and 12% of men experience a urinary tract infection at least once in their lifetime. Aminoglycosides are very effective antimicrobial agents. The emergence and spread of antibiotic resistance in Escherichia coli (E. coli) is becoming a global public health concern. The aim of this study was to determine the presence of ant(2'')-Ia and ant(4')-IIa genes in E....
The pool of antimicrobial resistance determinants in the environment and in the gut flora of cattle is a serious public health concern. In addition to being a source of human exposure, these bacteria can transfer antibiotic resistance determinants to pathogenic bacteria and endanger the future of antimicrobial therapy. The occurrence of antimicrobial resistance genes on mobile genetic elements,...
