Blastocystis is an unusual enteric protozoan parasite of humans and many animals whose pathogenic potential is still controversial. To increase the understanding of the molecular epidemiology of this emerging parasite and due to its potential impact on public health, its subtypes (STs) in Iranian symptomatic and asymptomatic individuals were determined. A(More)
Dear Editor, Foot infections are one of the important causes for hospitalization of patients with diabetes and the leading cause of morbidity in diabetic patients. Diabetic foot lesions may present as ulceration, gangrene, charcot joint, or fracture and are associated with amputation if not treated promptly. 3 The proper management of these infections(More)
BACKGROUND Cryptosporidium is a worldwide protozoan parasite and one of the most common causes of infection and diarrhea in humans and cattle. The aim of the present study was determination of subtypes of Cryptosporidium among children with diarrhea in Tehran by sequence analysis of the highly polymorphic 60-kDa glycoprotein (GP60) gene. METHODS Fecal(More)
BACKGROUND The present study was aimed to investigate molecular diversity of Echinococcus granulosus isolates collected from human clinical samples using two mitochondrial genes cox1 and nad1 in Iran. METHODS Forty seven human hydatid cysts were collected through surgery from two hospitals in Tehran during 2010-2012. To determine the fertility of(More)
BACKGROUND Clostridium difficile infection (CDI) is major growing problem in hospitals and its high incidence has been reported in recent years. OBJECTIVES The aim of this study was to investigate the antimicrobial susceptibility patterns of C. difficile clinical isolates against antibiotics commonly used for treatment CDI in hospitalized patients.

An immunosuppressed man was admitted to hospital with diarrhea and a history of urinary tract infection. He was subjected to treatment with antibiotics. The patient died of putative severe sepsis. The etiological agent was a carbapenemase producing isolate of Bacillus circulans with resistance to all prescribed antimicrobial agents.
BACKGROUND Campylobacter infections may lead to serious conditions, including septicemia or other invasive forms of the disease, which require rapid and accurate laboratory diagnosis and subsequently appropriate antimicrobial therapy. The aim of this study was to compare the species distribution and antimicrobial susceptibility pattern of Campylobacter spp.(More)
BACKGROUND Enterococcus faecium is a multi-resistant nosocomial pathogen causing infection in debilitated patients. Vancomycin-resistant enterococcus faecium (VREfm) are a major concern and increased dramatically worldwide especially in hospitals environment. The current study focused on determining the high prevalence and distribution patterns of(More)
AIM The purpose of this study was to investigate the prevalence of enteropathogenic Escherichia coli (EPEC) and shiga toxin producing E. coli (STEC) strains in healthy broilers in Iran. BACKGROUND STEC and EPEC strains as diarrheagenic E. coli are among the most prevalent causative agents in acute diarrhea. Domestic animals, mainly cattle and sheep, have(More)
BACKGROUND In this study, the efficacy of nitazoxanide in the treatment of Helicobacter pylori isolates, which were resistant to metronidazole, was examined. METHODS One hundred twenty two patients who underwent endoscopy examinations at Kasra and Laleh hospitals in Tehran from November 2014 to July 2015 were enrolled. Helicobacter pylori strains were(More)
