Background: Klebsiella pneumoniae is one of the most important hospital opportunistic pathogens that have become resistant to many antibiotics due to biofilm formation. The aim of this study was to synthesize copper nanoparticles using Artemisia scoparia extract, to investigate its antimicrobial and anti-biofilm effects against K. pneumoniae strains. Methods: In this experimental study, 100 cli...
Introduction & Objective: Vacuolar proteinase is an aspartic enzyme in Candida albicans (C. albicans) that is expressed by VAP gene and plays an important role in the development of systemic candidiasis. The aim of this study was to evaluate VAP gene expression in C. albicans strains isolated from patients with systemic candidiasis. Materials & Methods: The evaluation of VAP gene expression ...
Background and purpose: The aims of this study were to evaluate the antibiotic resistance of Healthcare-associated Methicillin-resistant Staphylococcus aureus (HA-MRSA) and Community associated MRSA (CA-MRSA)-resistant strains of Staphylococcus aureus strains and to investigate the frequency of different types of spa typing, SCCmec I, II, III, IV, V, and type IV, among the strains of MRSA isol...
Background and Objective: Methicillin resistance in Staphylococcus aureus is an increasingly important clinical problem. A chromosomal gene, mecA, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in Staphylococcus aureus. We evaluated the validity of disk diffusion test by using oxacillin, methicillin an...
conclusions the results revealed that the strains under study could be epidemically related. it seems that an alternative subtyping method is needed to study the relationship among clinical s. sonnei strains and their transmission. here, we reported for the first time, two strains of s. sonnei with a different pcr-rflp pattern for ipah gene. results all shigella isolates were positive for both ...
We sequenced the complete genome of the widely used C57L/J mouse inbred strain. With 40× average coverage, we compared the C57L/J sequence with that of the C57BL/6J and identified many known as well as novel private variants. This genome sequence adds another strain to the growing number of mouse inbred strains with complete genome sequences and is a valuable resource to the scientific community.
conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...
Mouse inbred strains remain essential in science. We have analyzed the publicly available genome sequences of 36 popular inbred strains and provide lists for each strain of protein-coding genes that acquired sequence variations that cause premature STOP codons, loss of STOP codons and single nucleotide polymorphisms, and short in-frame insertions and deletions. Our data give an overview of pred...
Background: Pseudomonas aeruginosa is an opportunistic pathogen and a major cause of nosocomial infections. The aim of this study was to evaluate the frequency and determine the antimicrobial resistance in clinical strains of Pseudomonas aeruginosa isolated from different parts of Tehran hospitals in 2013. Methods: In this cross-sectional study, during the six-month period, 180 samples were ...
Background and Aim: Increased prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and treatment of infections due to these resistant strains is one of the most important health challenges. In this study, antimicrobial resistance patterns of Staphylococcus aureus isolates from patients were determined to commonly prescribed and last-resort antibiotics, and methicillin-resistant Stap...
