ABSTRACT
Dirofilaria immitis and repens are mosquito-borne filarioids of zoonotic concern, which primarily cause canine heartworm disease (HWD) subcutaneous dirofilariosis, respectively. The geographical distribution these nematodes is constantly changing, due to many factors such as the colonization by new invasive mosquito species, increased movement animals absence chemoprophylactic strategies in non-endemic regions. Although HWD has always been considered endemic northern Italy, an increase prevalence this recorded last decades central southern We describe southernmost hyperendemic European focus Pelagie archipelagos. From June November 2020, 157 dogs 46 cats were sampled Linosa Lampedusa islands for detection modified Knott's, rapid antigen molecular tests.
