the last two decades have seen a massive growth in the application of dna technology in histocompatibility and immunogenetics. this review summarises the history and application of dna methods in this area.
conclusions as about 70% of methicillin-resistant isolates belonged to sccmec iii, the present study can conclude that, over an 8-year period, only one dominant and stable clone of mrsa strain was found in tabriz hospitals. this finding could be a result of incorrect medical orientations, inadequate infection controlling policies, and insufficient preventive approaches. objectives the current s...
conclusions the outcome of this study indicates a higher discriminatory power of the rflp analysis based on the spa gene compared to the coa gene. moreover, the results of our study reveal that the resistance rate of s. aureus to some antimicrobial agents including linezolid is a growing concern. background antibiotic resistant staphylococcus aureus is a serious public health problem worldwide....
ABSTRACT Typing of bacteria is an important part of epidemiological studies on nosocomial infections. Bacterial identification methods have dramatically improved in recent years, which is mainly due to advancements in the field of molecular biotechnology. In many cases, molecular techniques have replaced phenotypic typing methods. Currently, a wide r...
Abstract Background and Objective: A high level of homogeneity observed within all bacteria in the Mycobacterium tuberculosis complex makes a property that seriously challenges traditional biochemical-based identification methods of these pathogens in the laboratory. The work presented here was conducted to characterize Mycobacterium tuberculosis complex isolates in Golestan, Northern Iran. ...
background: fusobacterium necrophorum as a non-spore-forming gram-negative anaerobic bacillus is an important human and animal pathogen. it may cause severe systemic infections (lemierre's syndrome) and some other infections. the aim of this study was to subtype fusobacterium necrophorum by using pcr methods. materials and methods: twenty five strains of fusobacterium necrophorum subspecies fun...
background and purpose: by using advanced detection/identification methods, the list of emerging uncommon opportunistic yeast infections is rapidly expanding worldwide. our aim in the present study was sequence-based species delineation of previously unidentified yeasts obtained from a clinically yeast collection. materials and methods: a total of twenty three out of the 855 (5.7%) yeast isolat...
Conidia of Aspergillus species are widely distributed and ubiquitous in outdoor and hospital environments. There are high numbers of patients with weakened immune systems, therefore Aspergillus infections are increasing in hospitals. Molecular typing of Aspergillus strains obtained from patients and their environment is an important tool for epidemiological and public health studies. Fingerprin...
