Serological diagnosis of amoebiasis by immunofluorescence.
A positive serological diagnosis of amoebiasis could be made by immunofluorescence in 66 of 78 established cases, taking a serum titre of 16 or higher as diagnostic: at this level there were no false positives among 94 control sera. The test is simple and may be carried out on amoebic smears stored for several months in 2-octanol. The serological activity is largely confined to the IgG immunogl...
متن کاملSerological tests for syphilis.
Many of the nontreponemal or serological tests for syphilis involve the detection of serum antibodies (reagin) which are not directed against a component of the causative organism itself but may arise as a result of pathological changes brought about by proliferation of Treponema pallidum in host tissue. Test antigens for the detection of reagin are lipoidal, the main active component being the...

متن کاملSerological Tests
Serological diagnosis of an acute infection can be done by the demonstration of seroconversion and/or agent-specific IgM antibodies in the serum samples. Seroconversion describes 4 fold or more increase in antibody levels of the serum samples which is collected at the acute and convelescent phase (10-15 days intervals) of an infection. As the detection of seroconversion is time-consuming, the a...
متن کاملSerological tests for staphylococcal infection.
The need for a reliable serological test for occult staphylococcal infection has long been evident, especially for the diagnosis of lesions of the spine and hip. Earlier reports on the use of the anti-a-haemolysin (Lack and Shelswell, 1955; Lack, 1957), and anti-leucocidin tests (Towers and Gladstone, 1958; Towers, 1961) have placed us in a position to compare the value of these two tests; anti...
