Passive cutaneous anaphylaxis tests were used to examine the IgE responses of cats repeatedly infected with the filarial nematode Brugia pahangi. Specific IgE was usually detected only in those cats that killed their adult worms and rarely in those cats in which adult worms survived for long periods. We suggest that this specific IgE is actively involved in killing adult worms in the lymphatics.
