What causes neural larva migrans?
The infecting dose of larvae may be related to the disease presentation; when large numbers of embryonated eggs are ingested, larvae may be more likely to penetrate the central nervous system, causing neural larva migrans. Death or permanent disability is a common outcome of neural larva migrans due to Baylisascaris.
What are visceral larva migrans in animals?
