Studies on the prevalence and biology of Blastocystis spp. isolated from zoonotic reservoirs in Malaysia / Farah Haziqah Meor Termizi
This first epidemiological study showed positive infection in broiler chicken despite reared in farming method least prone to contamination, adding to the understanding of the biology, transmission as well as distribution of this organism in animals living in close association to humans and highlights their zoonotic potential.

Five subgroups of Blastocystis hominis isolates from symptomatic and asymptomatic patients revealed by restriction site analysis of PCR‐amplified 16S‐like rDNA
DNA polymorphism of Blastocystis hominis isolates was examined by the amplification of a gene fragment coding for the 16S‐like rRNA and results show that there are 5 B. hominis subgroups none of which was found to be significantly correlated with the reported disease. Expand
Blastocystis sp. puesta al día sobre su papel parasitario
Blastocystis sp. a single-celled, anaerobic parasite of great genetic variability in the intestine of animals and humans of worldwide distribution and the one with the highest prevalence amongExpand
Eukaryome Impact on Human Intestine Homeostasis and Mucosal Immunology: Overview of the First Eukaryome Congress at Institut Pasteur. Paris, October 16–18, 2019.
The human intestinal eukaryome comprises a diverse set of eukaryotic organisms living in the intestinal lumen. These are in permanent or transient interaction with commensal organisms such asExpand
Association of Blastocystis subtype 3 and 1 with patients from an Oregon community presenting with chronic gastrointestinal illness
Using a real-time LightCycler PCR assay, Blastocystis was detected in nine patients from a metropolitan area of Corvallis, Oregon who presented with diarrhea, abdominal pain, fatigue, joint pain, skin rash and psychiatric co-morbidity. Expand

The findings of this study agree with previous reports that the different Blastocystis subtypes have low host-specificity, comprising isolates from humans and various animal hosts and suggests evidence for zoonotic transmission of the parasite and cross-transmissibility among heterogeneous hosts. Expand
Evidence of plasmotomy in Blastocystis hominis
Trichrome and acridine orange staining evidence for the existence of nucleic acid suggestive of division of nucleus into multinucleate forms with the respective cytoplasm dividing giving rise to two or three progeny B. hominis is provided. Expand
Analysis of the ITS region and partial ssu and lsu rRNA genes of Blastocystis and Proteromonas lacertae
The hypothesis that Blastocystis is most closely related to P. lacertae, a parasite of reptiles, is supported, and that it should be regarded as an unusual stramenopile. Expand
Genomic Analysis of Blastocystis hominisStrains Isolated from Two Long-Term Health Care Facilities
This study presents the first molecular evidence of possible human-to-human B. hominisinfection between and/or among two small communities. Expand
Phylogenetic analysis of Blastocystis isolates from different hosts based on the comparison of small-subunit rRNA gene sequences.
If Blastocystis isolated from animals are capable of infecting humans, the number of animals found to be infected with BlastocyStis could represent a large potential reservoir for infection of humans. Expand

Evidently, the Cambrian diversification of animals strongly influenced evolutionary rates, within clades already present in marine communities, implying an important role for ecology in fueling a Cambrian explosion that extends across kingdoms. Expand
The stramenopiles from a molecular perspective 16S-like rRNA sequences from Labyrinthuloides minuta and Cafeteria roenbergensis
Abstract Comparisons of 16S-like ribosomal RNA sequences from the heterotrophic marine flagellate Cafeteria roenbergensis Fenchel et Patterson, the slime net Labyrinthuloides minuta Watson et RaperExpand
Blastocystis in humans and animals: morphology, biology, and epizootiology.
Publisher Summary This chapter reviews the biology and epizootiology of Blastocystis. The various experimental attempts to induce different forms of Blastocystis hominis (B. hominis) in culture areExpand
Only tubular, tripartite mastigonemes (flagellar hairs) characterized all studied taxa of chromophytes/oomycetes as a monophyletic assemblage. Expand
Protein and DNA evidence for two demes of Blastocystis hominis from humans.
Analysis of 10 stocks of Blastocystis hominis isolated from human stools revealed two discrete groups of organisms. Proteins of the two groups were immunologically distinct and hybridization withExpand

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
Phylogenetic placement ofAthelia bombacina, Aureobasidium pullulans, andColletotrichum gloeosporioides inferred from sequence comparisons of small-subunit ribosomal RNAs
Complete nucleotide sequences of the small-subunit ribosomal RNA (16 S-like rRNA) coding regions from Athelia bombacina, Aureobasidium pullulans, and Colletotrichum gloeosporioides were determined and found to be related more closely to Neurospora crassa and Podospora anserina than it is to the ascosporogenous yeast, Saccharomyces cerevisiae. Expand
SDS-PAGE and immunological analysis of different axenic Blastocystis hominis strains.
At least two variants with different polypeptide patterns and antigens exist in the anaerobic human parasite Blastocystis hominis from different sources and the biological significance of these findings is discussed. Expand
Phylogenetic relationships between chlorophytes, chrysophytes, and oomycetes.
Comparisons of similarity values or inspection of phylogenetic trees constructed by distance matrix methods reveal a very close relationship between oomycetes and chrysophytes. Expand
