| blastocystis | A genus of protozoa of the suborder blastocystina. It was first classified as a yeast but further studies have shown it to be a protozoan. (12 Dec 1998) |
|---|---|
| blastocystis hominis | A species of parasitic protozoa found in the intestines of humans and other primates. It was classified as a yeast in 1912. Over the years, questions arose about this designation. In 1967, many physiological and morphological b. Hominis characteristics were reported that fit a protozoan classification. Since that time, other papers have corroborated this work and the organism is now recognised as a protozoan parasite of humans causing intestinal disease with potentially disabling symptoms. (12 Dec 1998) |
| blastocystis infections | Infections with protozoa of the genus blastocystis. The species b. Hominis is responsible for most infections. Surveys have generally found small numbers of this species in human stools submitted for parasitologic studies, with higher positivity rates and organism numbers being reported in aids patients and patients with other immunosuppressive diseases. Symptoms include abdominal pain, diarrhoea, constipation, vomiting, and fatigue. (12 Dec 1998) |
| blastocyte | An undifferentiated blastomere of the morula or blastula stage of an embryo. Origin: blasto-+ G. Kytos, cell (05 Mar 2000) |
| blastocytoma | <tumour> A neoplasm composed chiefly or entirely of immature undifferentiated cells (i.e., blast forms), with little or virtually no stroma. Synonym: blastocytoma, embryonal carcinosarcoma. Origin: blasto-+ G. -oma, tumour (05 Mar 2000) |
| blastoderm | In many eggs with a large amount of yolk, cell division (cleavage) is restricted to a superficial layer of the fertilized egg (meroblastic cleavage). This layer is termed the blastoderm. In birds it is a flat disc of cells at one pole of the egg and in insects an outer layer of cells surrounding the yolk mass. (18 Nov 1997) |
| blastodermal | Relating to the blastoderm. (05 Mar 2000) |
| blastodermic disk | The aggregation of blastomeres of a telolecithal ovum after cleavage has occurred. (05 Mar 2000) |
| blastodermic ectoderm | External layer of the blastula. (05 Mar 2000) |
| blastodermic layers | The primordial cell layer's on the yolk surface of a telolecithal egg; in the earliest stages they consist of protoderm, and they later differentiate into ectoderm, endoderm, and mesoderm. (05 Mar 2000) |
| blastodermic vesicle | In mammalian development, cleavage produces a thin walled hollow sphere, whose wall is the trophoblast, with the embryo proper being represented by a mass of cells at one side. The blastocyst is formed before implantation and is equivalent to the blastula. (18 Nov 1997) |
| blastodisk | 1. The disk of active cytoplasm at the animal pole of a telolecithal egg. 2. The blastoderm, especially in very young stages when its extent is small. (05 Mar 2000) |
| blastogenesis | <biology> Multiplication or increase by gemmation or budding. Origin: Gr. Sprout + E. Genesis. Source: Websters Dictionary (01 Mar 1998) |
| blastogenic | Relating to blastogenesis. (05 Mar 2000) |
| blastoid | <zoology> One of the Blastoidea. Source: Websters Dictionary (01 Mar 1998) |
