Dog heartworms Angiostrongylus vasorum and Dirofilaria immitis cause severe parasitological diseases; the importance of these parasitosis is growing due to their health impact on animals, the possible zoonotic implications and the recent spreading across several European countries and previously non-endemic areas. The aim of this study is to update the epidemiological scenario of cardiopulmonary nematodes A. vasorum and D. immitis in dogs of Sardinia island and to perform a morphological identification of larvae by the use of the Baermann and Knott techniques respectively and the molecular characterization of the mitochondrial cytochrome c oxidase subunit I (cox1) and the second ribosomal transcribed spacer region (ITS-2) of larvae L1 of A. vasorum. In the present study, 3.4% (5/146) of dogs resulted positive at Baermann technique for A. vasorum while 8.9% (61/684) to D. immitis. If on one side A. vasorum can be considered an emerging parasite in Sardinia, the parasitic pressure and the risk of infection for D. immitis in the island seems to be increased compared with the recent past.

The cardiopulmonary nematode Angiostrongylus vasorum can cause severe disease in dogs, including coagulopathies manifesting with bleeding. We analysed A. vasorum excretory/secretory protein (ESP)-treated dog plasma and serum by N-terminome analysis using Terminal Amine Isotopic Labelling of Substrates (TAILS) to identify cleaved host substrates.

The nematode is responsible for a vector-borne disease affecting canines and humans worldwide, known as cardiopulmonary dirofilariasis. An accurate and early diagnosis is of the utmost importance for effective disease management. While traditional microscopy-based methods remain invaluable, they have inherent limitations.

Article Synopsis
- 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.

Article Synopsis
- Angiostrongylus vasorum, or French heartworm, is a parasitic nematode mainly affecting canines, with cases expanding in North America, particularly in Newfoundland, Nova Scotia, and now Tennessee.
- Recent cases in Tennessee included a black bear and a coyote, both found to have verminous pneumonia, indicating the presence of this parasite in the region.
- Genetic analysis showed these Tennessee cases are closely related to European strains, highlighting the growing threat A. vasorum poses to wild and domestic canids in North America and the need for increased monitoring.
