brucellosis is a widespread zoonotic disease causing considerable economic and public health problems. despite animal vaccination, brucellosis remains endemic in some areas such as iran, especially in the western iranian province of hamadan. we sought to detect some of the most common virulence-associated genes in brucella isolated from human blood cultures to determine the prevalence of some v...

conclusions prevalence of fbe and aap was significantly different from similar studies, yet frequency of bhp was in accordance with other studies. prevalence of icaa and is256 was not significantly different from some studies while a significant difference was observed when results were compared with some other studies. results of the 59 s. epidermidis, fbe was found in 89.8%, while aap and bhp...

conclusions the high rate of mdrpa and its ability to produce biofilm is an alarm for public health. the statistical analysis showed that biofilm production in the mdrpa isolates was significantly higher than that in the non–mdrpa isolates (p < 0.001). background pseudomonas aeruginosa possesses a variety of virulence factors and infections caused by multidrug-resistant p. aeruginosa (mdrpa) in...

pertussis is still endemic and the recently resurgence of the disease caused by bordetella pertussis has been shown in many countries. the polymorphism of the virulence genes of b. pertussis and lack of any information about the allelic variation between the iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxs1, prn, fim3 and cya to understand the diffe...

conclusions the results of the current study designate the important role of medical samples as reservoirs of resistance inducing elements. early detection of vre with their virulence trait will help to prevent the spread of vancomycin resistant enterococcus species. supervision for antibiotic usage in hospitals, especially for last option antibiotics, can prevent the spread of resistant isolat...

conclusions s. aureus can easily contaminate the chicken nugget and this contamination is usually associated with significant presences of virulence genes. consumption of these nuggets certainly is associated with gastrointestinal diseases. therefore, some food safety and quality standards should be applied and performed in most of the iranian food units to control growth of s. aureus and its v...

introduction: despite high level of vaccination against pertussis‚ whooping cough has re-emerged as a health threat, especially in infants. this could be related to expansion of bordetella pertussis with novel alleles for virulence factors including the pertussis toxin promoter, ptxp3. compared to ptxp1 strains‚ ptxp3 strains produce more pertussis toxin which results in immune suppression and ...

background the most common hospital-acquired pathogen is pseudomonas aeruginosa. it is a multidrug resistant bacterium causing systemic infections. objectives the present study was carried out in order to investigate the distribution of virulence factors and antibiotic resistance properties of pseudomonas aeruginosa isolated from various types of hospital infections in iran. patients and method...

to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...

background shiga-toxigenic escherichia coli is an important human pathogen cause of diarrhea, hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans is a significant public health. objectives the aim of this study was to determine the molecular characteristics and antimicrobial resistance properties of shiga toxigenic escherichia coli (stec) strains wit...
