The amplification of "high" (H) and "low" (L) multispecific antibody responses achieved respectively by H and L lines of selection GP represents a valuable tool in the genetic study of host-infection interactions. These lines were obtained by bidirectional selective breeding for high (HGP) or low (LGP) antibody production to natural complex antigens. HGP and LGP parental lines and reciprocal F1 hybrids, as well as their F2 segregants and backcrosses were submitted to immunization and challenge with rabies virus CVS strain. Acquired resistance was 1000-fold higher in HGP than LGP mice, with a dominance effect to low antibody production observed in F1 hybrids. An association between high antibody response and acquired resistance (P < 0.001) in F2 segregant mice was noticed. The genetic study was performed in these several populations, with a single dose of 104.5-fold LD50 CVS. We could demonstrate 3 independent loci regulating the anti-rabies antibody production, that are distinct, at least in part, from the 10 genes controlling the antigen selection response (sheep erythrocytes) of selection GP.

UI	MeSH Term	Description	Entries
D007113	Immunity, Innate	The capacity of a normal organism to remain unaffected by microorganisms and their toxins. It results from the presence of naturally occurring ANTI-INFECTIVE AGENTS, constitutional factors such as BODY TEMPERATURE and immediate acting immune cells such as NATURAL KILLER CELLS.

D011818	Rabies	Acute VIRAL CNS INFECTION affecting mammals, including humans. It is caused by RABIES VIRUS and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. Important animal vectors include the dog, cat, bat, fox, raccoon, skunk, and wolf.

D011819	Rabies Vaccines	Vaccines or candidate vaccines used to prevent and treat RABIES. The inactivated virus vaccine is used for preexposure immunization to persons at high risk of exposure, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis.

D011820	Rabies virus	The type species of LYSSAVIRUS causing rabies in humans and other animals. Transmission is mostly by animal bites through saliva. The virus is neurotropic multiplying in neurons and myotubes of vertebrates.	Rabies viruses

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
