In this case report we describe a 49 year-old man who presented with chronic urticaria, angioedema and soft stool consistency. During diagnostic examinations Hashimoto’s thyroiditis was found even though the patient never had clear symptoms of this disease. Blastocystis hominis was isolated through a stool microbiologic examination, implicating that this parasite can cause the development of Ha...

context blastocystis hominis is a unicellular protozoan found commonly in the intestinal tract of humans and many other animals with multiple subtypes, which tend to be specific to the host. we aimed to apply a meta-analysis for studies of protozoan pathogens in order to obtain a general overview of the prevalence and genotype analysis of blastocystis spp. in iran. results we included 40 eligib...

The activities of n-hexane, dichloromethane and methanol extracts from five anti-diarrheic Thai medicinal plants, Acacia catechu (Fabaceae) resin, Amaranthus spinosus (Amaranthaceae) whole plant, Brucea javanica (Simaroubaceae) seed, Piper longum (Piperaceae) fruit and Quercus infectoria (Fagaceae) nut gall were tested against the in vitro growth of fresh isolates of the intestinal protozoan pa...

edigraphic.com Blastocystis hominis is a strict anaerobic protozoan that occurs in the intestine of humans and other mammals (Zierdt, 1991). Recently, phylogenetic analyses of ribosomal RNAs place B. hominis within the straminopiles (Silberman et al., 1996). Its pathogenic role in human beings is still disputed by some investigators (Markell and Udkow, 1986; Miller, 1988). The mechanism by whic...

OBJECTIVES To determine the associated clinical symptoms and prevalence of Blastocystis hominis (B. hominis).  METHODS Stool samples of 50,185 patients (26,784 males and 23,401 females) who were received at the Parasitology Laboratory of Yuzuncu Yil University Faculty of Medicine, Van, Turkey in the last 5 years were inspected microscopically using saline and iodine-stained wet-mount preparat...

Introduction: Blastocystis hominis is a parasite found in the stools of human as well as in the stools of other animals and recently its pathogenic potential has been increasingly recognized. Irritable Bowel Syndrome (IBS) is a digestive system’s disorder which is featured by change in bowel habits, abdominal pains and other symptoms similar to Blastocystis hominis infection. There is lit...

A patient with rheumatoid arthritis taking prednisone developed Blastocystis hominis acute diarrhoea, which was associated with increased inflammation and effusion of the left knee. B hominis organisms were found in synovial fluid from the left knee. The patient responded dramatically to metronidazole treatment. B hominis may become disseminated in immunosuppressed patients with diarrhoea and m...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the b. hominis subtypes and their prevalence rates in hamadan. patie...

Blastocystis hominis is an intestinal protozoan parasite. Although the pathogenic potential of this organism remains controversial, there is increasing evidence to suggest its involvement with human disease. Infections due to blastocystis homims are quite common in the tropics and third world countries owing to the prevailing unsanitary conditions. Almost 50% of the random faecal samples from A...
