The agglutination test in relation to typhoid fever

Ehrlich's Test in Typhoid Fever

come to be regarded by many as a medical curiosity of no clinical value whatever. The author, however, is convinced by his experience that the original work done by Ehrlich is not appreciated, siuce his own results fully coincide with those which Ehrlich obtained. After explaining the chemic&l nature of the reaction as far as it is understood, and the methods which Ehrlich advocated, he details...

Diazo test in typhoid fever.

Multi-drug resistant Salmonella typhi is causing serious concern country-wide. In the present study, a combination of cephloridine and gentamicin showed poor response (43.48%) despite in vitro sensitivity, in contrast to 100% response observed by Koul et al.(2). In vivo resistance to cephalexin and gentamicin despite in vitro sensitivity is known(6). On the other hand, ciprofloxacin was success...

The Vi-Agglutination Test in Enteric Fever

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, ...

Comparison of the Vi indirect fluorescent antibody test with the Widal agglutination method in the serodiagnosis of typhoid fever.

The indirect fluorescent antibody test using a whole Salmonella typhi Vi suspension as the antigen has been evaluated for the diagnosis of typhoid fever. Results using sera from 140 patients with S typhi infections proved on culture show the test to have good sensitivity. The test appears to be highly specific, although it has not yet been investigated with respect to typhoid vaccination or in ...
