Complement Fixation in Kala-Azar with the WKK Antigen

In our present issue we publish two articles in which the value of a complement-fixation test in early diagnosis of kala-azar is stressed. The antigen used is that of Witebsky, Klingenstein and Kuhn prepared from the tubercle bacillus, and originally intended for complement-fixation tests in tuberculosis. In tuberculosis, however, the results are very poor. Work in South America, however, revea...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

Complement-fixing antibodies in the sera of 534 lepromatous lepers under treatment with sulfones.

The methods employed in the titrations of antigen and serum are essentially those developed by WADSWORTH at al(16) in their studies on tuberculous sera. All reactions were evaluated in terms of the amount of complement required for 50-per-cent hemolysis under the conditions of the test; the preliminary incubation for fixation is 90 minutes in a 37°C water-bath and 15 minutes is allowed for hemo...
