Biliary lipids support serum-free growth of Giardia lamblia

Giardia Lamblia.

Biology of Giardia lamblia.

Giardia lamblia is a common cause of diarrhea in humans and other mammals throughout the world. It can be distinguished from other Giardia species by light or electron microscopy. The two major genotypes of G. lamblia that infect humans are so different genetically and biologically that they may warrant separate species or subspecies designations. Trophozoites have nuclei and a well-developed c...

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...

Participation of Actin on Giardia lamblia Growth and Encystation

BACKGROUND Microfilaments play a determinant role in different cell processes such as: motility, cell division, phagocytosis and intracellular transport; however, these structures are poorly understood in the parasite Giardia lamblia. METHODOLOGY AND PRINCIPAL FINDINGS By confocal microscopy using TRITC-phalloidin, we found structured actin distributed in the entire trophozoite, the label sta...

Inactivation of Giardia lamblia and Giardia canis cysts by combined and free chlorine.

Free chlorine and a combined organic N-chloramine (3-chloro-4,4-dimethyl-2-oxazolidinone, compound 1) were compared for efficacy as disinfectants against an admixture of cysts of Giardia lamblia and Giardia canis in water solution under a variety of test conditions; variables were pH, temperature, and water quality. In general, compound 1 was found to reduce the giardial excystation in the solu...
