Publikováno v: The Journal of parasitology. 76(5)

Trophozoites of Giardia ardeae were obtained from the great blue heron (Ardea herodias) and established in axenic culture using the TYI-S-33 medium. The generation time in culture for G. ardeae was 22-25 hr, which was 3-fold longer than for Giardia d

The detection of Giardia muris and Giardia lamblia cysts by immunofluorescence in animal tissues and fecal samples subjected to cycles of freezing and thawing

Autor: S L, Erlandsen, L A, Sherlock, W J, Bemrick

Publikováno v: The Journal of parasitology. 76(2)

The effects of freezing and thawing on the detection of selected Giardia spp. cysts were investigated using immunofluorescence, bright field microscopy, and low voltage scanning electron microscopy (SEM). Giardia muris cysts were obtained from either

Bovine Cryptosporidiosis: A Transmission and Scanning Electron Microscopic Study of Some Stages in the Life Cycle and of the Host-Parasite Relationship

Autor: W. J. Bemrick, N. F. Cheville, J. Pohlenz, H. W. Moon

Publikováno v: Veterinary Pathology. 15:417-427

Transmission and scanning electron microscopy of the ileal mucosae from 12 calves infected with Cryptosporidium sp. showed cryptosporidia free in the lumen and attached to epithelium. The attached parasites were interpreted to be extracellular and ad

Fecal Transmission of Calf Cryptosporidia between Calves and Pigs

Autor: H. W. Moon, W. J. Bemrick

Publikováno v: Veterinary Pathology. 18:248-255

All of 17 calves 1 to 21 days old and 23 of 24 1-day-old pigs inoculated orally with calf feces containing cryptosporidia oocysts became infected with cryptosporidia. Infectivity was maintained by discontinuous passage in calves, with storage in pota

Scanning electron microscopy of damage to the cecal mucosa of turkeys infected with Eimeria adenoides

Autor: W J, Bemrick, R F, Hammer

Publikováno v: Avian diseases. 23(4)

White Wrolstad turkeys were each inoculated with 100,000 Eimeria adenoides oocysts and killed on days 4-14 postinoculation. Tissue samples, obtained from 4 areas of the ceca comparable to areas examined in chickens infected with E. tenella in previou

SEM evidence for a new species, Giardia psittaci

Autor: S L, Erlandsen, W J, Bemrick

Publikováno v: The Journal of parasitology. 73(3)

The genus Giardia has been subdivided by Filice (1952) into 3 species, G. agilis, G. muris, and G. duodenalis, based on the morphology of the median body and subtle variations in the dimensions of trophozoites. Giardia trophozoites were isolated from

Scanning electron microscopy of damage to the cecal mucosae of chickens infected with Eimeria tenella

Autor: W J, Bemrick, R F, Hammer

Publikováno v: Avian diseases. 22(1)

A group of chickens were inoculated with 100,000 Eimeria tenella oocysts each. The birds were sacrificed on days 4-14 postinoculation. Tissue samples from 4 different areas of each cecum examined were obtained and processed by the osmium-thiocarbohyd
