  journal={Parasitology Research},
Blastocystis hominis cysts were concentrated from human faeces by repeated washing in distilled water and centrifugation on Ficoll-Paque. This procedure gave a concentrated suspension of cysts without yielding any non-cystic forms. The cysts were examined by both transmission (TEM) and scanning electron microscopy (SEM). Cysts were surrounded by a fibrillar layer that appeared porous in SEM. Many naked cysts without the fibrillar layer were also visible in SEM. They were variable in shape but… Expand

Observations on the ultrastructure and viability of the cystic stage of Blastocystis hominis from human feces
Surprisingly, chromatoid-like structures were found in the cytoplasm and nucleus of some of the cysts of Blastocystis hominis, which can survive in water for up to 19 days at normal temperatures but are fragile at extreme temperatures and in common disinfectants. Expand
Freeze-Fracture and Cytochemical Studies on the in Vitro Cyst Form of Reptilian Blastocystis pythoni
In the present study glycogen was cytochemically demonstrated at the ultrastructural level by an alkaline bismuth staining method in both cyst and non-cyst cells. Expand
Morphology and reproductive mode of Blastocystis hominis in diarrhea and in vitro
The in vitro culture of Blastocystis hominis in Roswell Park Memorial Institute (RPMI) 1640 medium containing 20% calf serum is described and three distinct morphological forms, vacuolar, granular and amoeboid, were distinguished in faeces and in vitro cultures. Expand
Detection of Blastocystis hominis: a controversial human pathogen
Clinical microbiology laboratories should start screening of stool samples for B. hominis from stool samples of patients attending the authors' hospital as it is an emerging pathogen. Expand
Recent advances in Blastocystis hominis research: hot spots in terra incognita.
This review describes and discusses recent advances in B. hominis research, with particular focus on new, and sometimes controversial, information that has shed light on its genetic heterogeneity, taxonomic links, mode of transmission, in vitro culture and pathogenesis. Expand

Preliminary results show that the drug in a single dose occasionally eradicated B. hominis, decreased the excretion of vegetative forms and induced the occurrence of cysts. Expand

The first reports of Blastocystis in the elephant, giraffe, Javan lutung, quokka, southern hairy nosed wombat and western grey kangaroo are described. Expand


Ultrastructure of Blastocystis hominis in human stool samples.
Results suggest that the vacuolated form of Blastocystis hominis may be an artefact of culture conditions, and that the form of B. hominis present in the gastrointestinal tract is avacuolar. Expand
A cyst-like stage of Blastocystis hominis.
A cyst-like form of Blastocystis hominis is described in stools and in culture that can withstand adverse environmental conditions and is infective to a new host remain to be determined. Expand

The pathology of B. hominis infections has been studied in gnotobiotic guinea pigs in which inflammation of the intestinal mucosa and invasion of the superficial layers were seen and limited studies of human pathology are available. Expand
Chromosomes of Blastocystis hominis.
Three stocks of Blastocystis hominis were adapted to monophasic culture in minimal essential medium (MEM) and the chromosomes of these stocks separated by field inversion gel electrophoresis (FIGE).Expand
Isolation ofBlastocystis from the cockroach (Dictyoptera: Blattidae)
Investigation of the cockroach as a possible vector would be of interest, as the mode of infection in humans is not known, and eight isolates of Blastocystis were obtained, indicating a high prevalence rate. Expand
