Inducing Active and Passive Immunity in Sheep to Paralysis Caused byDermacentor andersoni

Active and passive immunity, vaccine types, excipients and licensing.

Abstract Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or previous infection or by other non-immunological factors. This article reviews active and passive immunity and the differences between them: it also describes the four different commercially available vaccine types (live attenuated, killed/inactivated,...

The first report of lumbar paralysis in sheep due to nematode larvae infestation in Iran

A new Approach to active Immunization of Sheep by a combined Sheep pox and Anthrax Vaccine

Diagnosing limb paresis and paralysis in sheep

Paresis and paralysis are uncommon problems in sheep but are likely to prompt farmers to seek veterinary advice. A thorough and logical approach can aid in determining the cause of the problem and highlighting the benefit of veterinary involvement. While this may not necessarily alter the prognosis for an individual animal, it can help in formulating preventive measures and avoid the costs - bo...

Fc receptors are required in passive and active immunity to melanoma.

Effective tumor immunity requires recognition of tumor cells coupled with the activation of host effector responses. Fc receptor (FcR) gamma-/- mice, which lack the activating Fc gamma R types I and III, did not demonstrate protective tumor immunity in models of passive and active immunization against a relevant tumor differentiation antigen, the brown locus protein gp75. In wild-type mice, pas...
