Entamoeba moshkovskii and Entamoeba dispar are impossible to differentiate microscopically from the pathogenic species Entamoeba histolytica. There are limited data on the prevalence of these commensal parasites in Iran. We utilized a single-round PCR assay to determine the prevalence of E. moshkovskii, E. dispar, and E. histolytica in stool samples from(More)
The objective of this study was to assess the genotypic diversity associated with antimicrobial susceptibility of Salmonella serovars isolated from patients arriving with diarrhoea to six hospitals of Tehran, Iran. During 2007–2008, a cross-sectional convenience study was performed. Stool samples were screened for the presence of Salmonella, serotyped,(More)
Staphylococcus aureus is considered one of the most important food borne pathogens. A total of 111 isolates of S. aureus were cultured from raw milk samples during January 2009 to June 2009 from Tehran and Mashhad. The coagulase gene polymorphism and the prevalence of classical enterotoxin genes of S. aureus strains were determined by PCR-RFLP (restriction(More)
Monitoring of proteins involved in cellular life and death processes is of high scientific interest since it permits the elucidation of functional changes in a variety of diseases. In this study, we have developed a nanoLC-MS/MS assay for the simultaneous detection and quantification of 24 selected proteins that are known to be important for cellular(More)
Phylogenetic analysis of about twenty isolates ofShigella spp. was carried out using the nucleotide sequences of 16S rRNA, 23S rRNA and DNA gyrase B (gyrB) genes which was determined by directly sequencing PCR fragments. The results showed that the similarity based on 16S rRNA for specimens belonging to the same species ofShigella flexneri, Shigella boydii,(More)
OBJECTIVES A case-control study was conducted to investigate the epidemiology and clinical features of Blastocystis hominis among Iranian patients with and without GI symptoms. METHODS Six hundred and seventy patients with GI and Six hundred and seventy patients without GI symptoms were enrolled as cases and controls respectively during 2006-07. Standard(More)
Short-chain acyl-CoA dehydrogenase deficiency (SCADD) is an inherited disorder of mitochondrial fatty acid oxidation that is characterized by the presence of increased butyrylcarnitine and ethylmalonic acid (EMA) concentrations in plasma and urine. Individuals with symptomatic SCADD may show relatively severe phenotype, while the majority of those who are(More)
