Statistical Studies on Widal Reaction

Widal reaction in Kala-azar.

Kala-azar usually has an indolent course but it can present as an acute disease with fever, anorexia and vomiting(2,3). At times both the diseases are so closely similar in their presentation , that differential diagnosis is not always clear, Widal test, inspite of its limitations and fallacies is still w...

Correlation studies on Widal agglutination reaction and diagnosis of typhoid fever.

A total of 80 patients at the University of Uyo Teaching Hospital (UUTH) suspected of having enteric infections were screened for the presence of Salmonella species using blood, urine and stool samples along with Widal agglutination tests. Although 39 patients tested positive for the Widal agglutination test with titers ranging from 1:80 to 1:320, no Salmonella organism was encountered in some ...

The Prognostic Importance of the Widal Reaction in Typhoid Fever

come across cases which are clinically true cases of typhoid fever, but in which curiously enough the Widal reaction remains completely negative during the whole course of the disease, and some of these cases recover. My object in writing this note is to discuss these aberrant negative results in the Widal reaction. In some patients the Widal reaction has been observed to be positive in as high...

A Study on Clinical Value of the Widal Reaction and Its Variations in Typhoid Fever

or 1Hand what are their individual significance and value ? 4. Do the titres of ' 0 ' and ' H ' agglutinins vary or fluctuate in subsequent weeks ? If so, do they undergo similar fluctuation or independent of one another ? If such variations occur, what is their clinical significance ? 5. Are these variations, fluctuations, etc., of any value in forecasting the course of the disease, and progno...
