Total serum IgE and IgA antibody levels in healthy dogs of different breeds and exposed to different environments.
Total serum immunoglobulin (Ig) E and A levels were analysed in 233 healthy dogs as basis for comparison with atopic dogs in future studies. They were measured by ELISA in a group of non- colonised dogs of various breeds (group A) and three groups of colonised dogs including one German Shepherd and two Beagle kennels (groups B-D). IgE levels from non-colonised dogs were significantly higher than the ones of German Shepherds and Beagles C (P<0.05). IgA levels were alike in all groups except for the German Shepherds which displayed the lowest levels. Age and sex were not identified as common significant cofactors for IgE and IgA levels in all groups and IgE levels correlated negatively with IgA only in non-colonised dogs. In conclusion, IgE and IgA levels seem to be mainly influenced by genetic background. Thus use of total serum IgE as a diagnostic tool in the atopic dogs required extensive family data and therefore appears most suitable for research purposes within specific, well defined dog populations.
