Bottom Line: This disease is endemic in South Eastern United States, Australia, Europe, and Central and Southern Asia.Dirofilaria immitis and D. repens are the common mosquito borne filarial nematodes that cause infection.Several species of mosquitos including Mansonia uniformis, M. annulifera, and Aedes aegypti are the potential vectors for this disease in Sri Lanka.

ABSTRACT
Dirofilariasis is an uncommon zoonotic parasitic infection affecting human. The natural hosts for this nematode are animals such as dogs, cats, foxes, jackals, and raccoons. This disease is endemic in South Eastern United States, Australia, Europe, and Central and Southern Asia. Dirofilaria immitis and D. repens are the common mosquito borne filarial nematodes that cause infection. Several species of mosquitos including Mansonia uniformis, M. annulifera, and Aedes aegypti are the potential vectors for this disease in Sri Lanka. Two rare cases of dirofilariasis presenting as facial and intraoral lumps are presented.

Mentions: Two worms were preserved in 70% ethanol (v/v) after isolation from the nodules in the oral cavity. First, samples were scrutinized using a light microscope. Worms were identified using length, width, and appearance of the cuticle. Sex of the worm was determined, based on the presence or absence of vulval opening. Then, samples were further processed for scanning electron microscope (SEM) examination. Briefly, samples were air dried to evaporate ethanol. Next, samples were sectioned into parts (anterior end, middle part, and posterior end) separately. Then, sections were fixed separately on the stub using double side conducting carbon tape. After that samples were loaded into the sputter coater (SC7620, Quorum Technologies, UK) and samples were coated using gold palladium for 60 seconds. Finally, quoted samples were loaded into the scanning electron microscope (EVO/LS15, Carl Zeiss, Germany) and photos were taken at different magnification (Figures 5–8).
