Record of Wright, 1954 (Plagiorchiida: Renicolidae) in the Atlantic puffin (Linnaeus, 1758) arrived at the Canary Islands (Spain).

In the winter of 2022-2023, hundreds of the Atlantic puffins () appeared dead in the coast of the Canary Islands, a rare event considering their cold-living habits, normally occupying the North Atlantic Ocean. In this work, investigation about the parasites present in the Atlantic puffins found in the biggest islands of the Archipelago was carried out from a population portion. Necropsies of 39 birds were made and, during the examination of the urinary tracts, helminths were found.

Data on New Intermediate and Accidental Hosts Naturally Infected with in La Gomera and Gran Canaria (Canary Islands, Spain).

is a metastrongyloid nematode and the etiologic agent of angiostrongyliasis, a disease characterized by eosinophilic meningitis. This emerging zoonotic parasite has undergone great expansion, including in some regions of Europe and America. In the Canary Islands, the parasite was first discovered parasitizing on the island of Tenerife in 2010.

Zoonotic Bacteria in sp., an Invasive Species Introduced to the Canary Islands (Spain).

Lizards belonging to the genus are native to America and have been introduced in many parts of the world. In this work, a gastrointestinal microbiological analysis from sp. introduced to Tenerife, Canary Island, was carried out.

New Data on () Wedl, 1861 (Nematoda, Rictulariidae) Parasite of the Algerian Hedgehog Linnaeus, 1758 (Eulipotyphla: Erinaceidae) from the Canary Islands.

A redescription of the rictulariid nematode () Wedl, 1861, is made by means of light and scanning electron microscopy, including the first data on male specimens. The morphologic study was based on specimens recovered from two Algerian hedgehogs () from Tenerife and Gran Canaria islands (Canary Archipelago, Spain). The main characteristics of () males are the presence of 49-53 pairs of cuticular projections, the presence of one or two midventral precloacal fans (generally one), and the size of two unequal spicules, measuring 98-123 µm (right spicule) and 185-236 µm (left spicule).
