In the present study, we combined molecular detection, microsatellite genotyping, and neuropathology in stranded striped dolphins along the coasts of Campania and Calabria (Southern Italy). During the years 2018\u20132023, 93 cetaceans were necropsied. Brain tissues were screened for\n                    <jats:italic>T. gondii<\/jats:italic>\n                    DNA by Real-Time PCR targeting the 529-bp repeat element; positive samples (Ct range 21\u201330) were genotyped using eight microsatellite markers (TUB2, W35, TgM-A, B18, B17, M33, IV.1 and XI.1) and compared with reference strains by hierarchical clustering.

Genotyping revealed two genotypes, with GII in 10\/12 dolphins and GIII in 2\/12. In 10 evaluable cases, lesions ranged from mild non-suppurative meningitis\/meningoencephalitis to severe necrotizing encephalitis. IHC was positive in 7\/10 positive cases; tissue cysts were observed in proximity to lesions in the more severely affected brains.
