Abstract

Abstract: Within the genus Trichinella, Trichinella pseudospiralis is the only recognized non-encapsulated species known to infect mammals and birds. In October 2020, larvae recovered from muscle tissues of a wolf ( Canis lupus italicus ) originating from Molise Region, Central Italy, were molecularly confirmed as those of Trichinella britovi and T. pseudospiralis . This is the first detection of T. pseudospiralis from a wolf. In Italy, this zoonotic nematode was detected in a red fox ( Vulpes vulpes ), three birds ( Strix aluco, Athene noctua, Milvus milvus ) and five wild boars ( Sus scrofa ), and was also identified as the etiological agent of a human outbreak of trichinellosis in 2015. Since T. pseudospiralis is rarely reported from carnivore mammals in comparison to the encapsulated species frequently detected in these hosts, this finding opens the question of the role of carnivores as reservoirs for this parasite.
