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 ...

Fluorescent treponemal antibody studies.

Fluorescent antibody methods were originally introduced by Coons and associates in 1942. Included in this first publication was a procedure for antibody-fluorescein conjugation and a description of fluorescent reactions obtaincd by means of ultraviolet light microscopy. This communication, and later ones by other authors, indicated that fluorescent antibody procedures were practical for rapid a...

evaluation of confounders in toxoplasmosis indirect fluorescent antibody assay

background : the ifa test is one of the most usual methods for detecting anti- toxoplasma antibod­ies, although it has not any unique standardization. it seems that the microscopic judg­ment of results is an important confounder in ifa test. therefore, we conducted the present study to clarify the role of microscopic observer, and other confounders on the test. methods: eighty sera were collect...

Identification of Streptococcus mutans serotypes in dental plaque by fluorescent antibody techniques.

The presence of Streptococcus mutuns in dental plaque may be related to human dental caries. The cultural identification of this organism in plaque is not likely to be used routinely in a clinical or epidemiological situation. In an effort to develop a simpler diagnostic means of identifying Strep. mutans in plaque, antisera were prepared for the 5 known serotypes of Strep. mutuns. These immune...
