A 35-year-old man was admitted to a hospital in the south of Italy because of a periocular nodule and subpalpebral edema. The patient reported having been stayed in Tanzania five months before. Hematologic parameters were within the normality range, the Acanthocheilonema viteae ELISA did not detect significant levels of antifilarial IgG, and no further symptoms were described. The surgical inspection of the nodule led to the isolation of two filarioid parasites, identified as Dirofilaria repens by scanning electron microscope (SEM), and then by molecular assays. Knott's test did not reveal microfilaremia, whereas loop-mediated isothermal amplification and PCR detected D. repens DNA. The patient was treated with doxycycline, and he was found no more positive at the follow-up.

Rapidly changing environments are contributing to the spread of non-native species and their associated pathogens into new and vulnerable ecosystems, such as the Galapagos archipelago. These pathogens represent a significant threat to emblematic species. The Galapagos sea lion () (GSL) is an endangered and endemic pinniped that is increasingly at risk of acquiring infectious diseases due to interactions with introduced companion animals.

Background: Dirofilaria sp. "hongkongensis" is a putative Dirofilaria species, initially identified in subcutaneous nodules in humans in Hong Kong and in other South and Southeast Asian regions. While it differs genetically from the better-known zoonotic species, Dirofilaria repens and Dirofilaria immitis, information on the lesions caused by Dirofilaria sp.

"Human dirofilariasis, caused by filarial worms of the genus , is considered an emerging zoonotic filarial infection transmitted to humans by zoo-anthropophilic blood-sucking insects. The most common species causing human infections include and . In this case report, we present the case of a 60-year-old male patient who reported the presence of an intraoral swelling in the right maxillary vestibular region.
