On examination, he has periorbital edema and conjunctival hemorrhages. Vital signs show tachycardia (102 bpm) and tachypnea (20 breaths/min). Laboratory studies reveal marked eosinophilia (18% with absolute count 2,400/μL), elevated creatine kinase (1,200 U/L), and normal liver function tests. Which organism is the most likely causal agent?
- A)Strongyloides stercoralis
- B)Giardia lamblia

Encysted larvae in skeletal muscle drive the later symptoms. Ver explicação completa e trilha adaptativa →
