In species other than raccoons, which symptoms can be caused by Baylisascaris procyonis (raccoon roundworm)?

• A. CNS abnormalities
• B. Blindness
• C. Death
• D. All of the above

Answer: (D)

Baylisascaris procyonis eggs shed by raccoons can infect other species when ingested. The larvae migrate through tissues, often affecting the nervous system and eyes. When neural tissue is involved, you see CNS abnormalities such as ataxia, tremors, or seizures; when the eyes are affected, blindness can result; and with a heavy infection or susceptible host, the damage can be fatal. Because all of these outcomes can occur in non-raccoon species, the best answer is all of the above. This is why strict hygiene around raccoon feces and careful containment are crucial in rehab settings to prevent exposure.
