Complement-fixation test for lymphogranuloma venereum in non-specific urethritis.

A report by Bedson (1950) had not shown such an association, nor was any such relationship noted between non-specific urethritis and the results of the complement-fixation test for enzootic abortion in ewes by Willcox and Stamp (1953). In the latter investigation some 323 complementfixation tests for enzootic abortion in ewes were performed on sera from 123 patients with present or past non-specific urethritis, or their female consorts, and from 127 controls. Although no correlation was noted between the results of this test and non-specific urethritis, there was close agreement in the results of 265 parallel tests for enzootic abortion in ewes and lymphogranuloma venereum. Thus of 220 sera with a titre of 1/10 or below to the test for lymphogranuloma venereum, 218 (99 1 per cent.) exhibited a titre of 1/4 or below to the test for enzootic abortion. Of thirty sera positive to a titre of 1/8 or more to the test for enzootic abortion, 28 (93 3 per cent.) were positive to a titre of 1/20 or more to the test for lymphogranuloma venereum.
