The alkaline phosphatases of 29 strains of bacteria assigned by various authors to the genera Aerobacter, Klebsiella and Enterobacter were compared by the micro-complement fixation technique. On the basis of phosphatase resemblance, we recommend that all strains hitherto assigned to Aerobacter aerogenes and Enterobacter aerogenes be assigned to the genus Klebsiella.

The reactivity of histocompatibility antigens with serum antibodies and complement was studied in a short term model of allotransplantation. Lewis and DA rat kidneys were perfused with cytotoxic antisera and tissue sections analyzed for adsorption of fluorescent antibodies against gamma-globulin and complement (beta(1C) protein). Both, the presumed cytotoxic antibody and C were localized at sim...

The complement-fixation reaction in gonorrhcea has not been applied widely like the Wassermann reaction in syphilis. There are three reasons for this : (1) A good antigen has been believed to be not easy to prepare. Specially selected strains of the bacterium have been considered necessary, and special preparations, ' toxins ' and lysates have been preferred to the simple bacterial suspensions ...

A Serological study of Q fever in human beings and animals of Pakistan was performed using complement fixation test. Sera from 56 patients having different type of infection showed that 26.8 percent had been exposed to Q fever agent and had circulating antibodies against Coxie/la burnetii. In animals ser from 55 buffaloes, 35 cows, 60 sheep, 65 goats and 300 rodents were tested and showed a pre...

The gonococcal complement-fixation test (GCFT), based on the same principle as the Wassermann reaction (WR), has been in use for over 60 years. The test was applied for the first time, using a culture of the gonococcus as antigen, by Muller and Oppenheim (1906) to establish the diagnosis in a case of arthritis. Teague and Torrey (1907) suggested that negative results in the GCFT were due to dif...

Through the researches of Wassermann and his collaborators it has been established that syphilitic sera may contain substances which in the presence of other substances derived from syphilitic organs are capable of fixing complement, so that upon the subsequent addition of red corpuscles and homologous hemolytic amboceptor hemolysis is impeded. This phenomenon was originally interpreted as mean...

A macroscopic (tube) complement fixation test for poliomyelitis, using infected tissue culture fluids, is described. The test was applied to 27 individuals with a clinical diagnosis of poliomyelitis. In 18 patients it was possible to make a laboratory diagnosis of poliomyelitis on the basis of a rise in complement-fixing antibody titer and in 4 others on the basis of a high stationary antibody ...

A new latex agglutination (LA) test (Wampole Laboratories, Cranbury, N.J.) for detection of antibody to herpes simplex virus was compared with a reference complement fixation (CF) method in a premarket evaluation. Of 102 serum samples tested, 19 were LA negative and CF negative, 79 were LA positive and CF positive, and 4 were LA positive and CF negative. An enzyme immunoassay (M. A. Bioproducts...
