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...
The objective of this study was to characterize the C. jejuni IAL2383 strain isolated from humans in Brazil. Transcripts for the racR, dnaJ and ciaB genes were found and flaA, plda and cadF genes were present in the genome and bacteria was sensitive to most of the important antimicrobials used to treat humans. C. jejuni IAL2383 is a good experimental model to analyze the interactions with cells.
چکیده تقریباًَ نیمی از جمعیت جهان حامل هلیکوباکتر پیلوری در قسمت بالایی دستگاه گوارش خود هستند. البته شیوع این عفونت در کشورهای جهان سوم بالاتر است. کلونیزاسیون هلیکوباکتر پیلوری همواره منجر به التهاب مزمن معده شده که می تواند به زخم معده، سرطان معده و یا لنفوم malt تبدیل شود. اگرچه درمان چند دارویی رایج، در ریشه کنی این باکتری موفق می باشد ولی مشکل ازدیاد مقاومت دارویی هنوز باقی مانده است. بناب...
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...
From 300 stool samples, 58 Campylobacter strains were isolated by standard microbiological and biochemical methods. Of these, 40 strains were identified as Campylobacter jejuni and 5 as Campylobacter coli. The presence of flaA (100%), cadF (100%), racR (100%), dnaJ (100%), pldA (100%), ciaB (95%), virB11 (0%), ceuE (82.5%), cdtA (97.5%), cdtB (97.5%), cdtC (97.5%), and wlaN (7.5%) genes was det...
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...
