ANSWERS

1. B. ELISA- Enzyme linked immunosorbent assay - used to detect HIV. It is not a confirmatory test, only screening test. Confirmatory test is Western Blot test.
WIDAL done for Typhoid.

MRI for soft tissues.

USG for visceral examination.

2. C. Common cold is a viral disease (rhinoviruses). Highly infectious. Viral diseases have no effect by antibiotics.

3. B. Hay fever- Allergic rhinitis (High levels of IgE)

4. C. common cold and AIDS

 Typhoid- Salmonella typhi (B) Tuberculosis - Mycobacterium tuberculosis   (B)

Ringworm - fungus Dysentry can be viral and bacterial.

H is for hemaglutinnin

N is for neuraminidase

ANSWERS

M1. A. P. Falciparum - causes recrudescence of malaria causing fever , damage to kidneys leading to haemoglobinuria- hence called black water fever.

M2. B. P. Malariae has longest incubation period.

M3. D. Malaria

M4. B. Sporozoites are sickle shaped- stored in salivary gland of anophles.
