The etiology of an outbreak of gastroenteritis in humans cannot always be determined, and ∼25% of outbreaks remain unsolved in New Zealand. It is hypothesized that novel viruses may account for a proportion of unsolved cases, and new unbiased high-throughput sequencing methods hold promise for their detection. Analysis of the fecal metagenome can reveal the presence of viruses, bacteria, and pa...

this study was carried out of determine the prevalence of intestinal parasites and effects of some demoghraphic factors on the central district of Kerman city.in this study ,2104 stool samples were randomly collected(1219 specimens from urban areas and 885 from the surrounding villages of Kerman city) in 1991.the samples were examined by formalin-ether concentration method.the results showed th...

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder of uncertain etiology. Several studies have proposed the possible role of intestinal parasites in the pathogenesis of IBS. We aimed to summarize the epidemiological studies that describe a possible link between intestinal parasites and IBS, with special interest in endemic areas for intestinal parasitism such as South Amer...

Introduction: Intestinal parasitic infections are very common in developing countries and affect mostly children. Day care centers are places where children are more susceptible to acquire intestinal parasites. Material and Methods: This cross-sectional study was conducted to determine the prevalence of intestinal parasites among children who attend to day care centers in Yazd city. Eighty hu...

background: intestinal parasites of humans are important health problems of most communities, especially those situated in tropical and subtropical areas. this study was carried out in rural population of mazandaran province, northern iran, during 2004-2005, with the purpose of achieving a better understanding of the distribution of intestinal protozoan parasites in this province. methods: a to...

Strains (115) of Bacteroides fragilis were identified at the subspecific level and were tested for susceptibility to ampicillin, cephalothin, chloramphenicol, clindamycin, penicillin, and tetracycline using an agar dilution technique. We tested the following strains: B. fragilis subsp. distasonis, 12; B. fragilis subsp. fragilis, 39; B. fragilis subsp. ovatus, 10; B. fragilis subsp. thetaiotaom...

The aim of this study was to analyze the susceptibility trends to seven antibiotics of Bacteroides fragilis group isolates based on three survey studies performed by the Committee of Anaerobic Bacteria between 1989 and 2002. Fifty three, 82 and 65 B. fragilis group isolates were collected during each period. The antimicrobial agents included were: ampicillin, ampicillin-sulbactam (2:1), cefoxit...
