Question

Widal test is used for susceptibility of
A. Malaria
B. Typhoid
C. Cholera
D. Yellow Fever

Answer 1

Hint: Widal test is a serological test which is used to detect enteric fever.
It measures the titers of antibodies against the bacteria.
It was given by George-Fernand widal in 1896.

Complete answer: In order to solve this question we need to know about enteric fever and Widal test
Enteric fever is also known as typhoid fever.
It is a systemic illness caused by infection due to salmonella typhi.
The salmonella typhi enters the peyer patches of the small intestine and multiplies causing bacteremia (bacteria present in your bloodstream).
Further, they cause ulceration and bleeding in the small intestine.
Some of the clinical features of typhoid are:
1. Headache
2. Constipation
3. Epistaxis
4. Bronchitis
5. Rose spots
6. Confusion and coma
7. Fever
Laboratory diagnoses are:
1. Widal test
2. Blood culture
3. Typhi dot test
4. Indirect haemagglutination test
Complications are:
A. Intestinal
1. Hemorrhage
2. Peritonitis
3. Paralytic ileus
4. Peritonitis
B. Extra intestinal
1. Meningitis
2. Bone and joint infection
3. Encephalopathy
4. Nephritis
5. Pneumonia
6. Cholecystitis
7. Myocarditis
8. Granulomatous hepatitis
Treatment includes:
Drug dose: Ciprofloxacin, Amoxicillin, Cotrimoxazole, Chloramphenicol, Azithromycin.
Widal test is a serological test which measures the titers of antibodies against the bacteria.

So, the correct option is B. Typhoid.

Note: Malaria is caused by plasmodium vivax. It can be detected by the blood culture test, indirect haemagglutination test.
Cholera is caused by vibrio cholera. It can be detected by stool examination, rectal swab culture.
Yellow fever is caused by species of mosquito. It can be detected by blood samples.
