title: Detection of antibodies to Hypoderma lineatum in cattle by Western blotting with recombinant hypodermin C antigen.
abstract: The cDNA encoding the entire mature hypodermin C (HC) of Hypoderma lineatum was cloned and expressed in Escherichia coli as a glutathione S-transferase fusion protein using pGEX vector. The recombinant HC protein (rHC) was tested by Western blotting to detect antibodies to H. lineatum in cattle. Western blotting with rHC as antigen clearly differentiated between H. lineatum-infested cattle sera and normal cattle sera. Forty-six out of forty-eight serum samples from cattle in Central Mongolia were positive, whereas all 30 serum samples from cows in Hokkaido, Japan, were negative by Western blotting. The result of Western blotting was identical to that of a previously developed enzyme-linked immunosorbent assay. These data demonstrated that Western blotting, with rHC expressed in E. coli, might be a useful method for the diagnosis of cattle hypodermosis.
