Indirect fluorescent antibody technique in the serology of Toxoplasma gondii

Indirect Fluorescent Antibody Technique in the Serology of Toxoplasma Gondii.

The indirect fluorescent antibody technique has been used to titrate patients' antibody against Toxoplasma gondii. Rigorous tests of the immunological validity of the method were made. The reactions of the gamma globulin of human immune serum with Toxoplasma gondii and fluorescent rabbit anti-human gamma globulin were thus shown to be specific. Thereafter the technique could be used with confid...

Diagnosis of Intestinal Amoebiasis with Indirect Fluorescent Antibody Test

SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica ...

Serology of Legionnaires disease: comparison of indirect fluorescent antibody, immune adherence hemagglutination, and indirect hemagglutination tests.

An immune adherence hemagglutination (IAHA) test for the measurement of antibodies to Legionella pneumophila was developed and evaluated for the diagnosis of Legionnaires disease. Its sensitivity was compared to that of the indirect fluorescent antibody (IFA) test and a recently developed indirect hemagglutination (IHA) test. The sensitivity of the three tests appeared to be similar, with the I...
