Baylisascaris procyonis, the raccoon roundworm, causes severe larva migrans in humans. Early diagnosis with new assays and prompt treatment with albendazole improve outcomes for this serious zoonotic infection.
Area of Science:
- Zoonotic diseases
- Parasitology
- Neurology
Background:
- Baylisascaris procyonis (raccoon roundworm) is a significant zoonotic pathogen.
- It causes severe neural larva migrans (NLM), ocular larva migrans (OLM), and visceral larva migrans (VLM) in humans.
- Human baylisascariasis is increasingly recognized, necessitating clinical awareness.
Purpose of the Study:
- To provide an updated review of baylisascariasis, focusing on clinical relevance and diagnosis.
- To summarize human cases of neural larva migrans (NLM) and visceral larva migrans (VLM).
- To emphasize the importance of early detection and treatment.
Main Methods:
- Review of clinical cases of human baylisascariasis.
- Summary of diagnostic advancements, including recombinant antigen-based serodiagnostic assays.
- Analysis of treatment outcomes and recommendations.
Main Results:
- Most diagnosed human baylisascariasis patients are young children, but older cases are increasing.
- Recombinant antigen assays facilitate earlier diagnosis.
- Improved patient recovery with fewer sequelae has been observed with early intervention.
Conclusions:
- Early suspicion, diagnosis, and treatment with albendazole and corticosteroids are crucial for baylisascariasis.
- Increased public and medical awareness are vital for prevention and timely management of this zoonotic disease.
