Galactosamine, a Giardia filamentous cyst wall specific-sugar, is below the limits of detection in non-encysting trophozoites. Radiolabeling studies suggest that Giardia synthesize galactosamine… (More)

Giardia intestinalis trophozoites encyst when they are exposed to bile. During encystment, events related to the inducible synthesis of a novel N-acetyl-D-galactosamine (GalNAc) homopolymer, occur.… (More)

Encystment of the intestinal protozoan, Giardia, is a key step in the life cycle that enables this parasite to be transmitted from host to host via either fecal oral, waterborne, or foodborne… (More)

The oxygen uptake rate and metronidazole (MTZ) sensitivity in Giardia spp. cysts is greatly reduced from that in trophozoites. Thus, this project was undertaken to assess when in the encystation… (More)
High resolution backscatter electron (BSE) imaging of colloidal gold with field emission scanning electron microscopy (FESEM) depends upon selection of accelerating voltage, beam current, working… (More)

The small subunit ribosomal RNA (eukaryotic 16S rRNA) gene from Giardia trophozoites, isolated from 8 different prairie voles and 8 different muskrats, was amplified by the polymerase chain reaction.… (More)

Giardia lamblia which parasitize humans belong to either of two genotypes, A or B, based on specific signature sequences in the 5' end of the small subunit (16S) ribosomal RNA (rRNA) gene. These two… (More)
