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...

anti-adhesion therapy represents a potentially promising avenue for the treatment and prevention of tuberculosis in a post-antibiotic era. adhesins are surface-exposed microbial structures or molecules that enable pathogenic organisms to adhere to host surfaces, a fundamental step towards host infection. although several mycobacterium tuberculosis adhesins have been identified, it is predicted ...

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...

In this study, twenty-five strains of Mycobacterium tuberculosis resistant to isoniazid (INH) were isolated from patients with tuberculosis (TB). Nine strains (36%) were found to be virulent in guinea-pigs [root index virulence (RIV» 1 ]. The remaining sixteen strains (64%) were non-virulent (RIV <1). Of the nine strains resistant to INH as well as virulent to guinea-pigs, eight of them wer...

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...

[email protected] En los pacientes con IRC, los mecanismos que pueden explicar las elevaciones inespecíficas de TnIc son principalmente el mayor daño cardíaco y la función renal disminuida5. En nuestro estudio, las principales causas de elevación de TnIc en el grupo Otras Patologías Cardíacas (OPC) fueron la insuficiencia cardíaca congestiva, fibrilación auricular y taquicardia, mientras que en e...

Los varones han sido menos estudiados para el diagnóstico de osteoporosis. Basta con hacer una búsqueda en PubMed para comprobar que en la última década hay 26.556 trabajos publicados para la osteoporosis posmenopáusica frente a 8.523 en los varones. Se ha podido confirmar que un 30% de las mujeres ymenos del 10% de los varones con osteoporosis reciben antirresortivos. Se revisan el impacto de ...

La selección de componentes COTS (Commercial Off-The-Shelf) se realiza no sólo mediante el análisis de su calidad técnica sino también (y algunas veces principalmente) considerando cómo dichos componentes cumplen con los requisitos no-técnicos considerados relevantes. En este artículo proponemos un catálogo de factores no-técnicos que tiene como objetivo ayudar en la definición de este tipo de ...

the stripe (yellow) rust in wheat is one of the most important plant diseases in iran. since 1993 several epidemics have occurred in iran causing the breakdown of widely util-ized sources of resistance in wheat cultivars. twenty-seven pathotypes were identified during 2003 and 2004 in greenhouse tests. pathotypes 6e6a+, 6e22a+, 6e130a+, 6e134a+, 6e142a+, 6e158a+, 134e130a+ and 134e142a+ were mo...
