DETECTION OF TYPHOID CARRIERS BY AGGLUTINATION TESTS

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 ...

Typhoid Fever and Typhoid Carriers

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

New advances in the diagnosis of typhoid and detection of typhoid carriers.

For effective management of typhoid, diagnosis of the disease must be done with speed and accuracy. Development of such a test would require antigens that are specific for typhoid diagnosis. Attempts at finding the specific antigen have been carried out throughout the years. The finding of such an antigen can lead to carrier detection as well. Candidate antigens have been used in the developmen...
