Immune response in dogs infected with Ancylostoma duodenale

The relation between the level of serum immunoglobulins (IgG, IgM, IgA and IgE) percentage of T-lymphocyte and egg counts was studied in dogs infected with Ancylostoma duodenale. The serum IgG levels were significantly high and a marked significance was noticed also in the levels of IgM and IgE. An inverse relationship between the concentration of IgG and egg count and a direct association between the percentage of T-lymphocyte and IgG level was proved.
