Recent exposure to azoles is an important risk factor for infection with fluconazole-resistant Candida spp., but little is known about the role of antibacterial drug exposure in the emergence of drug-resistant Candida. We did a prospective nationwide surveillance study of candidemia in Israel and analyzed the propensity score-adjusted association between antifungal and antibacterial drug exposu...
BACKGROUND In Israel, <0.06% of the general population is infected with human immunodeficiency virus (HIV), with a much higher prevalence among specific groups. These groups are distinguished demographically by risk behavior category and by virus subtype. We investigated transmission of drug resistance within groups to assess the impact of these factors. METHODS Plasma samples from >15% of al...
Introduction: Infection is a common complication in multiply traumatized patients with the majority being nosocomial in origin. We report a series of three patients with open fractures of lower limb which were initially debrided and stabilized with external fixation. Subsequent conversion to definitive internal fixation was performed. All three patients subsequently suffered limb loss as a resu...
Background and objective: Human is the only host of hepatitis C virus. This virus has a positive single stranded RNA and lipoprotein envelop that has 7 confirmed genotypes. According to studies, genotypes 1a, 3a and 1b are the most common genotypes in Iran. No effective vaccine against HCV infection has been developed instead, advances in antiviral treatment using drugs that directly affect spe...
background and aims: lamivudine is amongst the antiviral for drug chronic hepatitis b treatment. during therapy with lamivudine, variants may emerge with ymdd mutation in the reverse transcriptase (rt) region of polymerase gene. this mutation might have a role in drug resistant for hbv. materials and methods: hbv dna extraction from serum sample of 88 patients, were subjected to nested pcr for ...
b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...
background and objectives : due to the extensive use of antibiotics, the spread of drug-resistant bacteria is one of the most worrisome threats to public health. one strategy that can be used to overcome potential shortcomings might be the inactivation of these organisms by photodynamic therapy. in this study, we have investigated whether drug-resistant wound-associated organisms (staphylococcu...
background: the emergence and propagation of different phylogenetic groups of antimicrobial-resistant e. coli have become a worldwide health concern in human and veterinary medicine. therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant e. coli is important for therapeutic and economic purposes. the aims of this study were to determine phylogenetic groups and patter...
Enterococci are part of the endogenous flora of human beings, are naturally resistant to several classes of antimicrobials, and are able to acquire resistance with relative ease. Currently the vancomycin-resistant enterococci are spread all over the world and treatment options for infections caused by it are often extremely limited. We assessed 193 vancomycin-resistant Enterococcus faecalis iso...
Influenza virus infection causes endemics almost yearly and pandemics occasionally. Although antivirals are available for the clinical treatment of influenza virus infection, the emergence of a drug-resistant virus has reduced the effectiveness of therapy and prophylaxis. Therefore, the timely detection of drug-resistant influenza viruses is important. A single-tube reaction using peptide nucle...
