Trophozoites containing ingested red blood cells in the stool are diagnostic of:
सही उत्तर: ख) Entamoeba histolytica
Erythrophagocytosis distinguishes invasive E. histolytica from the non-pathogenic E. dispar and E. coli. Giardia trophozoites are pear-shaped with two nuclei and do not ingest RBCs.

Hydatid cyst in humans is caused by the larval stage of:
सही उत्तर: घ) Echinococcus granulosus
Humans are accidental intermediate hosts of E. granulosus, with the dog as definitive host; the liver is the most common site. Taenia solium larvae cause cysticercosis instead.

Crescent- or banana-shaped gametocytes on a blood smear are characteristic of:
सही उत्तर: ख) Plasmodium falciparum
Only P. falciparum has crescent-shaped gametocytes; other species have round gametocytes. P. malariae is known for band forms of the trophozoite.

Broad, aseptate hyphae with right-angle branching in tissue suggest:
सही उत्तर: ग) Mucormycosis
Mucorales form wide, ribbon-like, pauci-septate hyphae branching at about 90 degrees; they cause rhino-orbital-cerebral disease, especially in diabetic ketoacidosis. Aspergillus has narrow septate hyphae branching at acute angles.

India ink preparation of CSF showing capsulated budding yeasts suggests:
सही उत्तर: घ) Cryptococcus neoformans
The thick polysaccharide capsule of Cryptococcus excludes India ink and appears as a clear halo; cryptococcal meningitis is common in advanced HIV. Cryptococcal antigen testing is more sensitive than India ink.

Warthin-Finkeldey multinucleated giant cells in lymphoid tissue are characteristic of:
सही उत्तर: घ) Measles
Measles virus causes cell fusion, forming Warthin-Finkeldey giant cells in lymphoid tissue. Chickenpox produces Tzanck cells (multinucleated epithelial cells) in skin lesions instead.

Hepatitis D virus can cause infection only in the presence of:
सही उत्तर: क) Hepatitis B virus
HDV is a defective RNA virus that needs HBsAg for its envelope, so it occurs as co-infection or superinfection with HBV. For this reason, hepatitis B vaccination also protects against HDV.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
During the 'window period' of acute hepatitis B, the marker that may be the only one detectable is:
सही उत्तर: ग) IgM anti-HBc
In the window period, HBsAg has disappeared but anti-HBs has not yet appeared, so IgM anti-HBc is the only marker of recent infection. Anti-HBs indicates recovery or vaccination.

-
The primary cellular receptor for HIV is:
सही उत्तर: क) CD4
HIV gp120 binds CD4 and then a co-receptor (CCR5 or CXCR4) for entry into helper T cells and macrophages. CD21 is the receptor for Epstein-Barr virus.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which of the following is a specific treponemal test for syphilis?
सही उत्तर: क) FTA-ABS
FTA-ABS detects antibodies directly against Treponema pallidum and remains positive for life. VDRL, RPR and Kahn tests are non-treponemal tests detecting anti-cardiolipin antibodies and are used for screening and follow-up.
