What is the human medical condition resulting from L3 larvae migration to the CNS?
Answer
Eosinophilic meningitis
When the infectious third-stage larvae (L3) of the rat lungworm migrate from the digestive tract into the bloodstream and subsequently breach the central nervous system (CNS), they cause inflammation and damage in the tissues of the brain and spinal cord. The resulting clinical condition observed in humans is medically termed eosinophilic meningitis. This diagnosis is supported by the characteristic increase of eosinophils, a type of white blood cell, detected in the spinal fluid during laboratory analysis.
