An ancestral secretory apparatus in the protozoan parasite Giardia intestinalis.
The protozoan parasite Giardia intestinalis belongs to one of the earliest diverged eukaryotic lineages. This is also reflected in a simple intracellular organization, as Giardia lacks common subcellular compartments such as mitochondria, peroxisomes, and apparently also a Golgi apparatus. During encystation, developmentally regulated formation of large secretory compartments containing cyst wa...
متن کاملGiardia intestinalis in Thailand: Identification of Genotypes
This study was undertaken to determine the genetic diversities of Giardia intestinalis isolated in Thailand. G. intestinalis cysts were collected from stool samples of 61 subjects residing in Bangkok or in rural communities of Thailand with and without gastrointestinal symptoms. All the cyst samples gave positive tpi amplicons (100% sensitivity), either of the 148- or the 81-bp tpi segments. Cy...
متن کاملLysosomal protein trafficking in Giardia lamblia: common and distinct features.
Giardia is a flagellated protozoan parasite that has to face different microenvironments during its life cycle in order to survive. All cells exchange materials with the extracellular medium through the reciprocal processes of endocytosis and secretion. Unlike more evolved cells, Giardia lacks a defined endosomal/lysosomal system, but instead possesses peripheral vacuoles that play roles in end...
متن کاملCloning of Thai strain Giardia intestinalis.
Axenic cultures of Giardia intestinalis trophozoites were successfully established from human fecal specimens and rectal swabs from dogs using sucrose gradient centrifugation to separate the cysts from fecal material, the excystation method of Robert-Thompson et al. and culture of the preparation in TYI-S-33 medium supplemented with human serum, vitamin mixture and piper acillin and amikacin an...
