Progressive loss of efficiency and fatal outcome resulting in massive economical losses forced veterinary authorities worldwide to start disease control including mass testing using complement fixation test
or malleinisation, and culling of positives.
The rickettsial complement fixation tests
had failed to demonstrate rickettsial antibody.
The virus was identified by using the complement fixation test
(CF), performed according to a described technique (10).
Active surveillance is conducted on the basis of clinical findings (abortions or orchitis) and an annual serologic test performed for every animal (rose bengal plate agglutination test or complement fixation test
); abortions and orchitis have to be bacteriologically confirmed.
Comparative evaluation of indirect hemagglutination and complement fixation tests
in serodiagnosis of cysticercosis.
In addition, of specimens from 27 students in three states serologically tested for histoplasmosis using immunodiffusion and complement fixation tests
, five were positive .
Complement fixation tests
against ZIKV and YFV antigens confirmed these interpretations.
