Question

Strongyloides stercoralis a) how to isolate (sputum, blood, fecal matter, etc.) b) where found-niche (water, air, food, etc.) c) what media (nutrient, starch, etc) d) selective growth condition (aerobic, anaerobic, etc.) e) identifying traits f) give virulent facts (those that help it be pathogenic) g) disease it may cause h) how each disease could be treated

Answer 1

STRONGYLOIDES STERCORALIS

(a) ISOLATION:-
- fecal matter

(b) NICHE:-
- soil
- water

(C) MEDIA:- modified agar plate

(D) SELECTIVE GROWTH CONDITION:-
-as the tapeworm lives in the intestinal contents which is oxygen free or anaerobic.
-The energy is derived from the breakdown of glycogen.

(E) IDENTIFYING TRAITS:-
- it is also called threadworm.
- it is parasite inside human intestine so is anaerobic.

(F) VIRULENCE FACTORS:-
-Strongyloides stercoralis larvae secrete a potent histolytic metalloprotease to their rapid migration.
-This protease has elastase activity and catalyzes the degradation of a model of dermal extracellular matrix.

(G) DISEASES:-
- strongyloidiasis

(H) TREATMENT:-
-Ivermectin is the drug of choice.
-This drug works by killing the worms in your small intestine.
-Albendazole is also helpful.
