An antigen detection assay for diagnosing filariasis.

In this study we examined the diagnostic potential of monoclonal antibodies (MAb) reactive to antigens of adult Brugia malayi, their microfilariae and antigen of Dirofilaria immitis. The MAb of clone 17E10, which were of IgM isotype, reacted to the inner cuticles and internal content of both male and female worms and also to the sheath and internal content of microfilariae in utero. However, these MAb did not react to the sheath of blood circulating microfilariae.
