Opsonization in vitro of Giardia lamblia trophozoites [PDF]

Infection and Immunity, 1981
The ability of peritoneal rabbit macrophages from immunized and nonimmunized animals to phagocytose Giardia lamblia trophozoites in the presence of serum was studied and compared in an in vitro system. The rabbits which served as the source of immune serum and macrophages were injected repeatedly at multiple sites (intramuscularly, subcutaneously, and ...

Lectin Activity in Entamoeba histolytica trophozoites [PDF]

Infection and Immunity, 1980
A lectin (carbohydrate-binding protein) has been found in extracts of a number of axenically grown trophozoites of Entamoeba histolytica strains. The strains grown in TYI-S-33 medium (Diamond et al., Trans. R. Soc. Trop. Med. Hyg. 72: 431-432, 1978) were HK-9, 200:NIH, and HM-1:IMSS.

Epithelial Cells Expressing EhADH, An Entamoeba histolytica Adhesin, Exhibit Increased Tight Junction Proteins

Frontiers in Cellular and Infection Microbiology, 2018
In Entamoeba histolytica, the EhADH adhesin together with the EhCP112 cysteine protease, form a 124 kDa complex named EhCPADH. This complex participates in trophozoite adherence, phagocytosis and cytolysis of target cells.

Induced encystment improves resistance to preservation and storage of Acanthamoeba castellanii

, 2008
Several conditions that allow the preservation, storage and rapid, efficient recovery of viable Acanthamoeba castellanii organisms were investigated. The viability of trophozoites (as determined by time to confluence) significantly declined over a period

Electron microscopical investigation of surface alterations on Giardia lamblia trophozoites after exposure to a cytotoxic monoclonal antibody. [PDF]

, 1996
The present study describes a transmission electron microscopical investigation of trophozoites from Giardia lamblia clone GS/M-83-H7 after exposure to monoclonal antibody (MAb) G10/4.

Balamuthia mandrillaris trophozoites ingest human neuronal cells via a trogocytosis-independent mechanism

Parasites & Vectors, 2022
Background Environmental protozoa need an adaptation mechanism to survive drastic changes in niches in the human body. In the brain parenchyma, Balamuthia mandrillaris trophozoites, which are causative agents of fatal brain damage, must acquire nutrients

Trophozoites of

, 2008
The human intestinal parasite Entamoeba histolytica causes amoebic colitis and amoebic liver abscesses. Three classes of amoebic molecules have been identified as the major virulence factors, the Gal/GalNAc inhibitable lectin that mediates adherence to ...

Single-Cell RNA Sequencing Reveals that the Switching of the Transcriptional Profiles of Cysteine-Related Genes Alters the Virulence of Entamoeba histolytica

mSystems, 2020
Entamoeba histolytica is an intestinal protozoan that causes human amoebic colitis and extraintestinal abscesses. Virulence variation is observed in the pathogenicity of E. histolytica trophozoites, but the detailed mechanism remains unclear.
