摘要

Trichinella pseudospiralis is a non-encapsulated species infecting both mammals and birds. In Italy, this species has been reported so far only in central regions (two nocturnal birds of prey, one red fox, and one wild boar) and in northeast regions (four wild boars). In November 2020, Trichinella sp. larvae were isolated by enzymatic digestion from muscle tissues of a red kite (Milvus milvus) specimen belonging to a population residing in the Basilicata region (Southern Italy). The parasite was identified as T. pseudospiralis by multiplex PCR, and the sequencing of the expansion segment V (ESV) region of the nuclear large subunit ribosomal DNA showed, in the microsatellite region, the polymorphism characteristic of the Palearctic population. This represents the first record of T. pseudospiralis in a red kite and the first report of this parasite in Southern Italy. The isolation of the parasite in a resident bird confirms that T. pseudospiralis is present, even if at low prevalence, in the Italian avifauna.
