Abstract

Infective larvae of Brugia pahangi were irradiated at 10, 25 or 45 krads by means of a Cobalt 60 source. In cats, 10 krads caused the worms to be stunted and sterile but allowed them to become 5th stage, migrate posterioly into the afferent lymphatic, and produce pathology.

25 krads prevented the worms from developing beyond the early fourth stage and from migrating away from the popliteal lymph node. No gross pathological reactions were evident. 45 krads produced the same effects as 25 krads but the longevity of the worms was much reduced.
