Which of the following symptoms can Baylisascaris procyonis cause in non-raccoon species?

1. Central nervous system abnormalities

2. Blindness

3. Death

4. All of the above

The correct answer is: All of the above

Baylisascaris procyonis, a raccoon roundworm, has the potential to affect various non-raccoon species, including humans. The larval stage of this parasite can migrate through the tissues of its host, leading to a range of severe symptoms due to its neurotropic nature. Central nervous system abnormalities can manifest due to the migration of larvae into the brain, resulting in neurological complications such as seizures or cognitive dysfunction. Blindness can also occur if the larvae migrate to the eyes, causing damage to the retina or other ocular structures, ultimately leading to vision loss. In severe cases, the overall tissue damage and resulting complications may lead to mortality, hence the potential for death in affected individuals. Thus, the correct answer encompasses the potential spectrum of serious health impacts that Baylisascaris procyonis can cause in non-raccoon species, reflecting the severity of the disease and its implications for wildlife and human health.
