Development of immunity in broilers continuously exposed to Eimeria sp

Autor: M I, Stiff, K W, Bafundo

Publikováno v: Avian diseases. 37(2)

A series of experiments was conducted to determine the time required to induce absolute immunity to three species of Eimeria in young broiler chickens continuously exposed to the parasite. Acquisition of immunity was measured by cessation of oocyst p

Autor: R J, Boisvenue, M I, Stiff, L V, Tonkinson, G N, Cox, R, Hageman

Publikováno v: American journal of veterinary research. 53(7)

Sixteen nonsibling sheep, approximately 12 months old, that were raised in a helminth-free environment, were used for 2 protection studies 6 months apart. Sheep were vaccinated weekly for 5 weeks by IM injection of fibrinogen-degrading proteins deriv

Effect of in vivo T-cell depletion on the effector T-cell function of immunity to Eimeria falciformis

Autor: J P Vasilakos, M I Stiff

Publikováno v: Infection and immunity. 58(6)

BALB/c mice were exposed to the enteric parasite Eimeria falciformis to produce a natural acquired immunity. The mice were then depleted of their effector T-cell function by in vivo administration of a cytotoxic Thy-1.2 mouse monoclonal antibody. T-c

Retroviral-associated eosinophilic leukemia in the cat

Autor: M G, Lewis, G J, Kociba, J L, Rojko, M I, Stiff, A B, Haberman, L F, Velicer, R G, Olsen

Publikováno v: American journal of veterinary research. 46(5)

Fourteen specific-pathogen-free cats were inoculated with a putative env gene recombinant feline retrovirus, PR8. An isolate of the Rickard strain of feline leukemia virus (FeLV-R), PR8, has the properties of both an exogenous (FeLV-R) and an endogen

Density-gradient sedimentation of feline bone marrow cells with polyvinyl-pyrrolidone-coated silica gel

Autor: M I, Stiff, G J, Kociba, R G, Olsen

Publikováno v: American journal of veterinary research. 47(8)

Feline bone marrow cells were separated based on their density distribution in a continuous polyvinyl-pyrrolidone-coated silica gel density gradient. Morphologic identification of cytocentrifuged preparations at specific densities revealed a progress
