The membrane potential of Giardia intestinalis.
Giardia intestinalis is a primitive microaerophilic protozoan parasite which colonises the upper intestine of humans. Despite the evolutionary and medical significance of this organism, its physiology is very poorly understood. In this study we have used a novel flow cytometric technique to make quantitative measurements of the electrical potential across the plasma membrane of G. intestinalis ...

Assistant Surgeon, Medical College Hospital, Calcutta, ortnerly Clinical Pathologist, Protozoology Depart-' ment, Calcutta School of Tropical Medicine.) The; role which Giardia inrcsnnuus may 'n the production of intestinal symptoms is still a disputed point. Nothing very definite can be stated one way or the other.

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...
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 کاملThe antioxidant potential of pyruvate in the amitochondriate diplomonads Giardia intestinalis and Hexamita inflata.
Giardia intestinalis and Hexamita inflata are microaerophilic protozoa which rely on fermentative metabolism for energy generation. These organisms have developed a number of antioxidant defence strategies to cope with elevated O(2) tensions which are inimical to survival. In this study, the ability of pyruvate, a central component of their energy metabolism, to act as a physiological antioxida...
