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.

- Metastrongyloid nematodes, including Angiostrongylus cantonensis and A. costaricensis, can cause severe diseases like eosinophilic meningitis in humans and are commonly found in the respiratory and circulatory systems of mammals.
- This study focused on identifying the gastropod species acting as intermediate hosts for these nematodes on Tenerife, Canary Islands, using a multiplex PCR technique.
- Researchers identified five metastrongyloid species in terrestrial gastropods, including two in the aquatic snail Physella acuta, highlighting the introduction of these parasites linked to non-native mammals and their spread in local ecosystems.
Trichinella spp. are cosmopolitan parasites that infect a wide range of hosts, with wildlife being the main reservoir of these zoonotic nematodes, especially red foxes (Vulpes vulpes) and wolves (Canis lupus) due to their apex position in the food chain in most European countries. The aim of this study is to investigate the prevalence of Trichinella spp.

- The rhabditid nematode causes strongyloidiasis in humans and can infect dogs, raising concerns about zoonotic transmission.
- A case of fatal disseminated infection due to this nematode was confirmed in a dog in the Czech Republic, supported by genotyping methods.
- The infection was linked to immunodeficiency from improper treatment, particularly corticosteroid use.
The metastrongyloid nematode Angiostrongylus cantonensis causes eosinophilic meningitis in a variety of homeothermic hosts including humans. Third-stage infectious larvae develop in gastropods as intermediate hosts. Humans are usually infected by intentional or incidental ingestion of an infected mollusk or paratenic host (poikilothermic vertebrates and invertebrates).
