Absorbed fluorescent treponemal antibody (FTA-ABS) test. Comparison with the FTA-200 and TPI tests on 1,056 problem sera.

Deacon and Hunter (1962) have shown that the fluorescent treponemal antibody (FTA) test detects two separate antibodies in syphilitic sera. One, a group antibody, reacts with other treponemes, such as the Reiter organism, Treponema microdentium, and Treponema zuelzerae, as well as with Treponema pallidum, presumably because of an antigen shared in common by these organisms. Removal of group ant...

Detection of Babesia microti-like parasite in filter paper-absorbed blood of wild rodents.

The first case of human babesiosis was reported in Japan. The epidemiology of this disease in Japanese nature remains unclear. In this study, 97 common field mice captured in Hokkaido, Japan, were examined. Blood specimens absorbed onto filter papers were eluted and tested by nested PCR using specific primers for the B. microti nuclear small subunit rRNA genome. Twenty-three percent (11/47) of ...

The use of dried whole blood absorbed on filter-paper for the Evaluation of Diphtheria and Tetanus Antitoxins in Mass Surveys

A recommended method for the preparation of monospecific Brucella sera.

A method is described in detail for the preparation of monospecific sera for typing brucella cultures. The importance of using entirely smooth cultures throughout the procedure is emphasized. A single intravenous injection of living brucellae in rabbits caused an active infection and the early appearance of high-titre antibodies. Sera obtained five to seven days after inoculation contained a hi...
