In Vitro Cultivation of Giardia Trophozoites
1984For more than half a century, methods and media have been available that enable the in vitro cultivation of most human intestinal protozoan parasites, including Entamoeba histolytica, other amoeba, Balantidium coli, and most of the alimentary flagellates (Dobell and Laidlaw, 1926).

Characteristics of thymidine transport in Giardia intestinalis trophozoites
Molecular and Biochemical Parasitology, 1991The transport of thymidine by the protozoan parasite Giardia intestinalis was examined at 0 degrees C. This temperature prevented attachment of the cells to vessel walls, so that a rapid sampling technique could be used. Thymidine influx (distinguished from gross uptake) was readily measurable at 0 degrees C and was specific and saturable.

Trophozoite Motility and the Mechanism of Attachment
1984Over 300 years ago, the first description of the free swimming movement of the intestinal protozoan Giardia was made according to Dobell (1920, 1932) by the great Dutch microscopist Anton van Leeuwenhoek, who described his observations on enteric “animalcules” or microorganisms in a famous letter addressed to Robert Hooke, Secretary of the Royal ...

Entamoeba histolytica: Fibrilar aggregates in dividing trophozoites
Experimental Parasitology, 2008Entamoeba histolytica trophozoite cytokinesis is dependent upon cytoskeletal elements such as filamentous actin and myosin. Here we present confocal and transmission electron microscopy studies of this process. A sequence in the formation of the contractile ring was shown with rhodamine-phalloidine staining.

Axenic Isolation of Viable Giardia muris Trophozoites
The Journal of Parasitology, 1991Large numbers of viable Giardia muris trophozoites were isolated from the duodenum of experimentally infected mice 6 days after inoculation with 1,000 G. muris cysts. A series of shaking, incubation, and washing steps in the presence of the broad-spectrum antibiotic piperacillin readily provided 4.9 +/- 1.5 x 10(5) G. muris trophozoites per mouse, free

The course of giardiavirus infection in the Giardia lamblia trophozoites
Experimental Parasitology, 1991The subcellular distribution of Giardia lamblia virus RNA in infected G. lamblia trophozoites was examined by in situ hybridization using biotinylated DNA probe and riboprobe. In G. lamblia Portland I strain, which is chronically infected by G. lamblia viruses, the viral RNA was detected in the cytoplasm as well as in the twin nuclei.

Oxygen Uptake In Cysts and Trophozoites of Giardia Lamblia
Journal of Eukaryotic Microbiology, 1993ABSTRACT. Oxygen uptake in cysts and trophozoites of the parasitic protozoan Giardia lamblia was examined. Both showed oxygen uptake activity, but that of cysts was only 10% to 20% that of trophozoites. Oxygen dependence of oxygen uptake in cysts and trophozoites showed oxygen maxima above which oxygen uptake decreased.

Methods of Isolating Trophozoites and Cysts
1984The culturing techniques discussed in Chapter 6 have facilitated the study of Giardia duodenalis trophozoites. However, only G. duodenalis from relatively few host species have been cultured. G. muris, G. agilis, and G. duodenalis from other hosts have not been cultured successfully.
