Immunity Against Parasites

Ups and downs of mucosal cellular immunity against protozoan parasites.

Immunity to internal parasites.

This review of internal parasitic diseases discusses methods of immune diagnosis, immune mechanisms of the host, and immunoprophylaxis against both protozoan and metazoan parasites of livestock. The limiting factors for immunodiagnosis are specificity and whether the host animals respond sufficiently to produce detectable serological responses. Because the array of antigens is so complex, the m...

Vaccination against cestode parasites.

Cestode parasites are important because they cause production losses, particularly in the sheep, beef and pig meat industries, and because some species are zoonotic parasites which cause serious disease in humans. Research on the development of vaccines to prevent infection with cestode parasites has concentrated on the taeniid cestodes. Two strategies can be adopted for vaccine research: vacci...

Immunity Against Avian Influenza Viruspanax Ginseng Polysaccharide (GPS) Can Improve Immunity Against H9N2 Avian Influenza Virus in Chickens

The humoral immunization potential of panax ginseng polysaccharide (GPS) against H9N2 avian influenza virus (H9N2 AIV) in chickens was investigated. The effects of GPS treatment before and during H9N2 AIV infection were determined in chicken embryo fibroblast (CEF) by MTT (3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide) assays and quantitative RT-PCR analysis of MHC and cytokine...
