Purged stools from 389 patients were evaluated microscopically for the presence of Blastocystis hominis. A total of five or more B. hominis cells per 40X field were observed in 43 patients (11%), and B. hominis was the only intestinal parasite present in 23 (6%) of these patients. Of the 23 patients, 19 had symptoms which included abdominal discomfort (15 patients), anorexia (10 patients), diar...

Eight hundred stool specimens were examined for the presence of Blastocystis Hominis (BH) by direct microscopy in Saline and Iodine and by concentration with formal saline ether method. Four hundred specimens were positive for Cyst or Ova of various parasites, of which BH was present in 12% samples. Of the total 400 positive cases 56% were positive for Protozoa and within this group 21% were po...

OBJECTIVE Numerous studies have revealed the presence of oxidative stress in parasitic infections. However, such studies were lacking in the Malaysian population. Previously, we have provided evidence that oxidative stress is elevated in Malaysians infected with intestinal parasites. Stool examinations revealed that about 47.5% of them were infected with the polymorphic protozoa, Blastocystis h...

Fresh stool examination was performed from 2,230 participants who enrolled in annual check-up programs of the Faculty of Medical Technology, Mahidol University in 1999-2000 and 2004. In this study, Blastocystis hominis infection was diagnosed by culturing in Jones' media. A total of 21% of fecal specimens (in 1999-2000) and 13.7% (in 2004) were positive for B. hominis. The vacuolated form was t...

Background: Blastocystis hominis is an intestinal parasite that can induce both intra- and extraintestinal symptoms. This article aims to describe the symptom findings in cases of HIV children co-infected with B. hominis. Case Presentation: A 3-year-old boy HIV/AIDS came diarrhea skin rashes. The direct smear technique, formalin-ethyl acetate concentration Jones medium culture, trichrome staini...

Blastocystis hominis (B. hominis) is one of the most common enteric parasite and a highly controversial protozoan parasite regarding its pathogenicity. It has been variably regarded as a commensal and as a pathogen. The aim of this study was to determine the prevalence of B. hominis in relation to sex and age. The purpose of this study was to get a clear idea about the existence of B. hominis i...

A prospective study was performed on a large outpatient population to evaluate the epidemiology and pathogenicity of Blastocystis hominis. Patients with stool specimens positive for B. hominis and negative for other bacterial and parasitic pathogens were sent a questionnaire and were requested to submit a follow-up specimen for ova-and-parasite examination. B. hominis was identified in 530 of 1...

Blastocystis hominis was considered to be a member of normal intestinal flora in the past; recently it has been accepted as a controversial pathogen. In this study 200 stool specimens of patients suffering from gastroenteritis were studies by applying direct microscopic stool examination and culture. 67% of these specimens showed single entropathogen, 20% mixed and 12% were negative. These resu...
