N2 - An ELISA procedure was developed for monitoring the specific IgE response in dogs to Dirofilaria immitis infection. The results of this assay correlated well with, and appeared to be more sensitive than, the passive cutaneous anaphylaxis test. The IgE ELISA values of the positive reference serum and the passive cutaneous anaphylaxis test results showed that a serum to negative absorbance ratio of 1.45 was statistically significally significant for discrinimination and was used to evaluate the specific IgE response in the sera from 90 clinically diagnosed heartworm cases. This ELISA procedure was more sensitive, as it detected 78% of the 90 cases as compared to a detection rate of only 43-47% by IgG ELISA or IFA. Sera obtained from 28 experimentally infected dogs at 4-week intervals for 20 weeks post-infection, were assayed for D. immitis-specific IgE by ELISA. A group of the infected dogs was also treated with diethylcarbamazine during the course of infection. All the experimentally infected dogs developed a specific IgE response, with treated dogs generally responding earlier.
