BACKGROUND The emergence of antimicrobial resistant strains of Escherichia coli has raised considerable interest in understanding the diversity and epidemiology of E. coli infections in humans. Virulence factors of E. coli determine the specific infections caused by this microorganism. OBJECTIVES This study aimed to determine the prevalence of eight E.(More)
Hepatitis C virus (HCV) is a major public health problem and a leading cause of chronic liver disease. An estimated 180 million people are infected worldwide. In this study, we developed a loop-mediated isothermal amplification (LAMP) assay for rapid detection of HCV genomic RNA and compared the sensitivity of LAMP with nested-PCR. A total of 30 blood(More)
BACKGROUND AND OBJECTIVE Diarrheal disease is still a major health problem, especially in developing countries, where it is considered as one of the leading causes of morbidity and mortality especially in children. Studies showed that Diarrheagenic E. coli (DEC) such as STES and EPEC strains are among the most prevalent causative agents in acute diarrhea,(More)
Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBLs-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the(More)
Many different methods have been presented by many researchers for characterizing cagA phosphorelation mothif, and based on different goals, these methods have been used in different studies. For example: PCR-RFLP and real-time PCR methods were presented by Owen et al. (2003), and different PCR methods were presented by Argent et al. (2005), Batista et al.(More)
CagA is a major virulence factor of Helicobacter pylori involved in host cell modulation. The C-terminal part of CagA containing the EPIYA motifs is highly variable and is important for the biological activity of the protein. The aim of this study was consideration of the changes in cagA tyrosine phosphorylation motifs (TPMs) of H. pylori. A set of 302 H.(More)
