Lectin-induced agglutination of trophozoites of different species and strains of Entamoeba. 1984

E Ghadirian, and E Meerovitch

In vitro agglutinability of trophozoites of three Entamoeba histolytica strains, cultivated under axenic conditions in the presence of concanavalin A (Con A), was shown to be related to the degree of their pathogenicity for experimental animals and of the concentration of Con A. Seven strains of E. invadens tested also agglutinated in the presence of Con A, and the degree of agglutination was proportional to the concentration of the lectin. Three strains of E. histolytica-like "Laredo-type" amebae, a strain of E. terrapinae, and a strain of E. moshkovskii agglutinated very slightly, only in the presence of the highest concentration of Con A tested.

UI	MeSH Term	Description	Entries
D003208	Concanavalin A	A MANNOSE/GLUCOSE binding lectin isolated from the jack bean (Canavalia ensiformis). It is a potent mitogen used to stimulate cell proliferation in lymphocytes, primarily T-lymphocyte, cultures.
D004404	Dysentery, Amebic	DYSENTERY caused by intestinal amebic infection, chiefly with ENTAMOEBA HISTOLYTICA. This condition may be associated with amebic infection of the LIVER and other distant sites.

D004747	Entamoeba	A genus of ameboid protozoa characterized by the presence of beaded chromatin on the inner surface of the nuclear membrane. Its organisms are parasitic in invertebrates and vertebrates, including humans.	Entamoebas
D004748	Entamoeba histolytica	A species of parasitic protozoa causing ENTAMOEBIASIS and amebic dysentery (DYSENTERY, AMEBIC). Characteristics include a single nucleus containing a small central karyosome and peripheral chromatin that is finely and regularly beaded.	Endamoeba histolytica,histolytica, Endamoeba
D000371	Agglutination	The clumping together of suspended material resulting from the action of AGGLUTININS.
D000656	Amoeba	A genus of ameboid protozoa. Characteristics include a vesicular nucleus and the formation of several PSEUDOPODIA, one of which is dominant at a given time. Reproduction occurs asexually by binary fission.	Ameba
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
