An international experiment on the Widal-reaction

Widal reaction in Kala-azar.

Enteric fever(l) and Kala-azar (vis-ceral leishmaniasis) are endemic, in and around Patna. 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...

The Widal Agglutination Reaction in Healthy Persons

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 Case of Enteric in Which the Widal Reaction Became Positive on the 49th Day

Condition on admission.?Temperature, 102?F.; pulse rate, 112; respirations, 26 per minute. The pulse was of fairly good volume and did not give any indication of internal haemorrhage at the time. Tongue, coated and moist. Abdomen, slightly tympanitic, resonant all over, and not rigid. No enlargement of spleen and liver. Bowels constipated for about four days after the last two hemorrhagic stool...

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...
