Canine filariosis caused by Dirofilaria immitis in Mozambique: a small survey based on the identification of microfilariae.

Dirofilaria immitis was diagnosed in 4 of 13 indigenous dogs from the Province of Zambézia, Mozambique, by acid phosphatase staining of microfilariae. The finding reconfirms the occurrence of the parasite in Mozambique after 3 decades and emphasises the need for extensive surveys. Additionally, in 1 of the infected dogs, microfilariae of Dipetalonema reconditum were detected, which is the 1st record of this parasite in Mozambique.
