Parasitic intestinal infestation seen in immuno-suppressed patient is –
**Core Concept**
The question targets the association between immunosuppression and parasitic intestinal infestations. Immunosuppression increases the susceptibility to opportunistic infections, including parasitic infestations, which can cause morbidity and mortality in immunocompromised individuals.
**Why the Correct Answer is Right**
In immunosuppressed patients, the weakened immune system fails to effectively combat parasitic infections. Cryptosporidiosis is a notable example, where the parasite *Cryptosporidium parvum* causes intestinal infestation. This occurs due to the inability of the host's immune system to mount an effective response against the parasite, leading to uncontrolled proliferation and severe gastrointestinal symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** Although giardiasis is a parasitic intestinal infestation, it is not specifically associated with immunosuppression.
* **Option B:** Amoebiasis can occur in immunocompetent individuals, making it less relevant to this specific scenario.
* **Option D:** Coccidiosis is a parasitic intestinal infestation, but it is not specifically linked to immunosuppression in the same way as cryptosporidiosis.
**Clinical Pearl / High-Yield Fact**
Immunosuppressed patients are at increased risk of opportunistic parasitic infections, including cryptosporidiosis, which can cause severe diarrhea and weight loss. Clinicians should consider this association when evaluating immunocompromised patients with gastrointestinal symptoms.
**Correct Answer:** C. Cryptosporidiosis
