Cerebral angiostrongyliasis is an acute inflammation caused by the infection of the nematode Angiostrongylus cantonensis that results in eosinophilic meningitis. The current immunological assay of choice is an immunoblot that detects antibodies to a 31 kDa protein present in crude extracts of the female worm. Recently we have identified diagnostic targets from excretion and secretion products and determined the composition of the 31 kDa antigen after 2-D gel electrophoresis and mass spectrometry. Here we cloned and expressed five proteins in prokaryotic and eukaryotic systems. Recombinant proteins were purified and analysed by Western blot assays and among them 14-3-3, Lec5 and ES7 were recognized by Angiostrongylus-specific serum, although the signal was weak.

Prostaglandin E2 (PGE-2) is synthesised by cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synthase 1 (mPGES-1). PGE-2 exhibits pro-inflammatory properties in inflammatory conditions. However, there remains limited understanding of the COX-2/mPGES-1/PGE-2 pathway in Angiostrongylus cantonensis-induced meningoencephalitis.

Aim: Angiostrongylus cantonensis, the leading cause of eosinophilic meningoencephalitis, is well established in eastern Australia. Prolonged wet weather in Queensland during 2021-2022 coincided with anecdotal reports of increased neuroangiostrongyliasis cases, prompting an evaluation of paediatric cases from 2013 to 2022.
Methods: This retrospective observational study reviewed children (0-16 years) with cerebrospinal fluid (CSF) eosinophilia (≥ 10% of the total CSF leukocyte count) and/or A.

Understanding the factors driving infection prevalence among host species is crucial for effective disease mitigation. Angiostrongylus cantonensis, the rat lungworm, causes neuroangiostrongyliasis and serves as an excellent model for studying infection dynamics across hosts. This study investigates the relative impact of encounter rates on A.

The rat lungworm is a zoonotic metastrongyloid nematode currently considered an emerging pathogen. Originating in Southeast Asia, this nematode has spread to tropical and subtropical parts of the world via its invasive rodent and gastropod hosts.On the island of Tenerife in the Canary archipelago, the invasion was recognized more than a decade ago.
