Ultrastructure of the cyst of Giardia lamblia

Autor: B Bjorvat, H G Sheffield

Publikováno v: The American journal of tropical medicine and hygiene. 26(1)

An isolation technique involving filtration and discontinuous density gradient centrifugation was utilized for obtaining Giardia lamblia cysts from human feces. Highly concentrated preparations of cysts were examined by electron microscopy. The cyst

Activity of the anticoccidial compound, lasalocid, against Toxoplasma gondii in cultured cells

Autor: M L, Melton, H G, Sheffield

Publikováno v: The Journal of parasitology. 61(4)

The activity of the anticoccidial drug, lasalocid, was tested against Toxoplasma gondii in cell cultures. Multiplication of parasites was inhibited by 0.05 mug/ml of lasalocid added to the cultures prior to adding the parasite inoculum, with the para

Sarcocystis sigmodontis n. sp. from the cotton rat (Sigmodon hispidus)

Autor: J P, Dubey, H G, Sheffield

Publikováno v: The Journal of parasitology. 74(5)

Sarcocystis sarcocysts were found in 3 of 4 cotton rats (Sigmodon hispidus) from Atlanta, Georgia. Sarcocysts were several centimetres long and were present only in skeletal muscles. The sarcocyst wall appeared thin (less than 1 micron), with minute

Effect of pyrimethamine and sulfadiazine on the fine structure and multiplication of Toxoplasma gondii in cell cultures

Autor: H G, Sheffield, M L, Melton

Publikováno v: The Journal of parasitology. 61(4)

Rhesus monkey kidney cell cultures were inoculated with Toxoplasma gondii organisms obtained from peritoneal fluid of mice infected with the RH strain. Pyrimethamine and sulfadiazine were added either singly or in combination to the cultures 4 hr aft

Ultrastructure of the cyst of Sarcocystis muris

Autor: H G, Sheffield, J K, Frenkel, A, Ruiz

Publikováno v: The Journal of parasitology. 63(4)

Cysts of Sarcocystis muris develop within muscle cells and each is bounded by a parasitophorous vacuole membrane. Closely spaced spherical blebs formed from this membrane extend into the muscle cell cytoplasm. A dense substance fills the cavity of th

Fine structure of immature cysts of Sarcocystis cruzi

Autor: N D, Pacheco, H G, Sheffield, R, Fayer

Publikováno v: The Journal of parasitology. 64(2)

Sarcocystis cruzi forms cysts in striated muscle of the bovine host following schizogony. The fine structure of the immature cyst within muscle fibers of the ventricular myocardium was studied in relation to its development and to the multiplication
