The dielectrophoretic collection spectra of antibiotic-sensitive and antibiotic-resistant strains of Staphylococcus epidermidis have been determined. These indicate that in the absence of antibiotic treatment there is a strong similarity between the dielectric properties of sensitive and resistant strains, and that there is a significant difference between the sensitive strains before and after...
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, ...
In this study, a relationship between antibiotic and heavy metal resistance was estimated among culturable bacterial strains of agriculture farm soap industry soil.A total 27 were isolated screened for their by supplementing LB agar medium with variable concentrations respectivestress. On LB-agar medium, soil harboured more cultivable (17 strains) as compared to the (10 strains).Minimum inhibit...
In the study, in addition to antibacterial effect of astaxanthin on Aeromonas hydrophila and A. sobria strains, presence virulence genes (Aero, act, ast, hylA) antibiotic resistance (tetC sulI) strains was investigated. Antibiotic profiles were also investigated as part study. Strains identified by conventional biochemical tests PCR assay using a 16S rDNA primer pair specific for hydrophila. Ac...
Background and Objective: Staphylococcus aureus bacteria is a common cause of hospital infections. Resistant strains of this bacterium are a major pathogen in causing disease and death in Iran and the world. Therefore, the aim of this study was to investigate the prevalence of mecA methicillin resistance gene and determine antibiotic resistance patterns in S. aureus strains isolated from clinic...
Antibiotic resistance occurs in the endogenous flora of exposed population in addition to pathogenic bacteria. This study was conducted to evaluate the distribution of antibiotic resistance genes among 63 isolates of Escherichia coli of Escherichia coli (E. coli) in diarrheic calves and poultry. According to the results, B1 and B2 were the most prevalent phylogroups of E. coli in calves and pou...
OBJECTIVES Determining the in vitro susceptibility to 11 antibiotics of Francisella tularensis subsp. holarctica strains belonging to the phylogenetic group B.13, from different areas of Hungary. METHODS Twenty-nine F. tularensis strains isolated between 2003 and 2010 from free-ranging European brown hares (Lepus europaeus) and a captive patas monkey (Erythrocebus patas) were collected from d...
Lactic acid bacteria, including lactobacilli, enterococci, leuconostoc and weissella species isolated from Iranian traditional fermented camel milk (Chal) were assessed for the incidence of virulence determinants (gelE, efaAfm, efaAfs, ace, espfs, cylM, cylA and cylB), sensitivity to various antibiotics and virulence phenotypes. The incidence of virulence genes was determined by polymerase cha...
Whether the presence of Candida spp. in lower respiratory tract (LRT) secretions is a marker of underlying disease, intensive care unit (ICU) treatment and antibiotic therapy or contributes to poor clinical outcome is unclear. We investigated healthy controls, patients with proposed risk factors for Candida growth in LRT (antibiotic therapy, ICU treatment with and without antibiotic therapy), I...
Nowadays, there is increasing interest in the production of functional foods, particularly probiotic foods. Lactic acid bacteria (LAB) particularly strains of Lactobacillus are important bacteria in food microbiology and human nutrition due to their ability to fermented food production and have received considerable attention as probiotics. The traditional fermented dairy foods as a rich source...
