A QUICK MACROSCOPIC TYPHOID AGGLUTINATION TEST

Macroscopic agglutination test for rapid diagnosis of human leptospirosis.

A commercially available slide agglutination test (SAT) for the diagnosis of human leptospirosis was evaluated by comparing it to an immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) and to the microscopic agglutination test (MAT). For all 108 patients, leptospirosis was diagnosed on the basis of a fourfold or greater increase in titer by MAT (seroconversion), and all but 1 of 24...

Detection of typhoid carriers by agglutination tests.

Use of the Vi agglutination test in the detection of chronic carriers of Salmonella typhi (S. typhosa) first was suggested by Felix et al. (1935). Since that time study of the test by many workers has resulted in the accumulation of a voluminous literature which has been reviewed by Klein (1943), Felix (1951), Landy and Lamb (1953), and Spaun (1957). Bhatnagar et al. (1938) recommended the use ...

Microcinematography of the Agglutination of Typhoid Bacilli.

The rapid slide agglutination test in the diagnosis of typhoid fevers and typhus.

Of 10,000 sera examined for infectious diseases by both the rapid slide agglutination and the tube agglutination tests, 128 were found positive for typhus fever and 257 for typhoid and paratyphoid infections. Of 84 of the last mentioned cases of typhoid and paratyphoid, which were confirmed by cultural examination, 45 (53.5%) were negative to the tube test, whereas only one (1.2%) was negative ...

Comparison of passive haemagglutination test with Widal agglutination test for serological diagnosis of typhoid fever in an endemic area.

A passive haemagglutination test, using sheep red blood cells sensitised with Salmonella typhi lipopolysaccharide, was compared with the Widal test for the serological diagnosis of typhoid fever in an endemic area. The results obtained on sera from 152 patients with bacteriologically confirmed typhoid and 183 patients who did not have typhoid were analysed in terms of sensitivity, specificity, ...
