Lectin binding by Giardia lamblia

Lectin binding by Giardia lamblia.

Surface carbohydrates of Giardia lamblia were examined using six plant lectins chosen because of their specificity for major carbohydrates moieties. The binding to axenically grown G. lamblia trophozoites was assessed in both a quantitative microagglutination assay and a fluorescence assay. Of the six lectins tested, wheat germ agglutinin (WGA) agglutinated the highest percentage (22.9 +/- 3.7%...

Binding of cholera toxin to Giardia lamblia.

Binding of cholera toxin to Giardia lamblia was demonstrated by two slightly different methods: an immunofluorescence technique using antibody to cholera toxin and anti-rabbit immunoglobulin G conjugated to fluorescein isothiocyanate, and a one-step fluorescence method in which G. lamblia was incubated with the B subunit of cholera toxin conjugated to fluorescein isothiocyanate.

Giardia Lamblia.

Nodular lymphoid hyperplasia by Giardia lamblia.

Clinical features of giardiasis vary greatly between individuals and may range from asymptomatic infection to severe malab− sorption syndrome. Whereas individuals with various forms of hypogammaglobu− linemia may show more severe disease and damage to the intestinal villi, AIDS patients do not appear to be at increased risk of severe giardiasis [1]. We present a case of duodenal giardiasis in a...

Giardia lamblia and Giardiasis

Introduction Ask the average outdoors person about Giardia lamblia, and they have certainly heard about it. Almost always, however, they are considerably misinformed about both the organism’s significance in wilderness water and the seriousness of the disease, giardiasis, if contracted. The amount of information easily found on the subject is voluminous. Unfortunately, almost all of it is flawe...
