RESUMO
Angiostrongylus cantonensis is an invasive nematode parasite that causes eosinophilic meningitis in many vertebrate hosts, including humans. This parasite is spreading rapidly through the six continents, with Europe being the final frontier. Sentinel surveillance may be a cost-effective strategy to monitor the pathogen's arrival to new geographical regions. Necropsy, followed by tissue digestion, is often used to recover helminth parasites from vertebrate host tissues, however, to detect brain parasites, this protocol is poorly utilized. Our brain digestion protocol is easily performed and 1) reduces false positivity and negativity, 2) provides accurate estimates of parasite burden and 3) helps establish a more precise prevalence. Early detection of A. cantonensis increases the efficacy of prevention, treatment, and disease control strategies for susceptible animal populations and humans.
