Abstract
Simian retrovirus type 2 (SRV-2) is a natural pathogen of Macaca fascicularis. Although SRV-2 may be endemic in macaque colonies, it is not necessarily detected in all individuals suggesting differential susceptibility to SRV-2; factors contributing to this susceptibility are not fully understood. We have investigated the role of host genetic origin on virus susceptibility. We have shown that high levels of anti-SRV-2 antibodies correlate with failure to establish persistent virus infection, thus we targeted our genetic analysis of virus susceptibility with an investigation of the role of the polymorphic macaque major histocompatibility complex (MHC) class II locus. DRB genotypes, both novel and previously characterised, were identified in individuals and family groups. A discordance with SRV-2 infection status suggests that an Mhc II DRB genotype is not overtly associated with the outcome of viral infection.
