Comparison of methods for coccidioidomycosis complement fixation.
A Laboratory Branch Task Force of the National Communicable Disease Center has proposed a standardized complement fixation procedure (LBCF) and an adaptation of this to microtitration techniques (MT) as uniform methods for performing complement fixation (CF) tests. A common procedure should make CF results from one laboratory more comparable to another. In addition, it would be preferable if th...
متن کاملComparison of coccidioidin and spherulin in complement fixation tests for coccidioidomycosis.
Coccidioidin, an extract from the saprophytic mycelial form of Coccidioides immitis, has been a very useful antigen preparation in serological tests for coccidioidomycosis. Its sensitivity has been very good for detecting most types of clinical disease, but tests with coccidioidin have been negative for 40% or more of patients with chronic pulmonary disease, the clinical entity which must be di...
متن کاملValue of the concomitant use of complement fixation and immunodiffusion tests in the diagnosis of coccidioidomycosis.
Complement fixation titers of 1:2 and 1:4 with coccidioidin are not always of diagnostic significance. The concurrent use of the complement fixation and immunodiffusion tests is an effective means for specific serologic diagnosis of coccidioidomycosis in patients with low levels of complement-fixing antibodies. In routine testing, it is recommended that only sera that are negative for complemen...
متن کاملComplement Fixation Tests in Pertussis.
Bordet and Gengou (1), in 1906, performed serological tests on pertussis employing the organisms which they discovered and claimed to be the causative agent of whooping cough as the antigen for the complement fixation test. They got a positive reaction in most cases of the disease. Yet, later investigations failed to confirm these results. Among those who confirmed their results were Renaux (2)...
متن کاملComplement Fixation Tests in Poliomyelitis **
Infection with poliomyelitis virus gives rise to complement-fixing (C-F) antibodies which may be detected with antigens prepared either from the brains of infected mice or tissue culture fluids, as shown with Type II by Casals et al."' and with all three types by Svedmyr et al.' These workers used sufficient antigen in each test to obtain maximum sensitivity. With this antigen concentration the...
