BACKGROUND Although antimicrobial resistance and persistence of resistant bacteria in humans and animals are major health concerns worldwide, the impact of antimicrobial resistance on bacterial intestinal colonization in healthy domestic animals has only been rarely studied. We carried out a retrospective analysis of the antimicrobial susceptibility status and the presence of resistance genes i...

conclusions: this study highlighted the need to establish antimicrobial resistance surveillance networks for p. aeruginosa to determine the appropriate empirical treatment regimens. the high prevalence of multidrug resistance and production of esbls in p. aeruginosa isolates confirms the necessity of protocols considering these issues in the hospitals. results: the resistance against broad-spect...

Title of Dissertation: CHARACTERIZATION AND MOLECULAR MECHANISMS OF ANTIMICROBIAL RESISTANCE IN FOODBORNE PATHOGENS Sheng Chen, Doctor of Philosophy, 2004 Dissertation directed by: Associate Professor Jianghong Meng Department of Nutrition and Food Science The emergence of antimicrobial resistance bacteria in both the medical and agricultural fields has become a serious problem worldwide. The u...

This study aims at molecular identification of Salmonella Infantis isolated from backyard chickens and the detection of their antibiotic resistance genes. A total of 46 Salmonella-suspected samples isolated from backyard chickens of northern Iran were collected. Serotyping was done by the traditional method and then confirmed by PCR. Antimicrobial susceptibility of the isolates against 13 antim...

Background and Objective: Enterococcal infections are considered the most common nosocomial infections. Nowadays, enterococci show high resistance to common antibiotics, especially vancomycin. Vancomycin-resistant Enterococcus faecium is one of the most common nosocomial infections, which is included in the World Health Organization priority pathogens list for research and development of new an...

Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance g...

High throughput genotyping is essential for studying the spread of multiple antimicrobial resistance. A test oligonucleotide microarray designed to detect 94 antimicrobial resistance genes was constructed and successfully used to identify antimicrobial resistance genes in control strains. The microarray was then used to assay 51 distantly related bacteria, including Gram-negative and Gram-posit...

The purpose of this study is to assess the impact low-frequency electromagnetic fields (LF-EMFs = 0.5 MHz) on phenotypic and genotypic levels concerning antibiotic resistance, antimicrobial-resistant (AMR) genes, resistance mechanisms Pseudomonas aeruginosa (P. aeruginosa). In study, bacterial isolates were exposed MHz then inoculated a new medium for assessment their sensitivity. results showe...

Objective(s): Clostridioides (Clostridium) difficile infection as a healthcare-associated infection can cause life-threatening infectious diarrhea in hospitalized patients. The aim of this study was to investigate the toxin profiles and antimicrobial resistance patterns of C. difficile isolates obtained from hospitalized patients in Shiraz, Iran.Mater...
