Abstract :

Dirofilaria immitis is one of the circulatory system parasite of dogs and the effects ofcardiopulmonary severe in animal's causes, according to the zoonotic of this parasite and toverify the primary infection of Dirofilaria immitis in the Sarab district, a cross sectional studywere conducted on 384 sheepdogs. ELISA tested sera. Seropervalence rate 13.5% (52/384) wasreported. The highest seroprevalence of Dirofilaria immitis in 4-6 years dog 21.7% (37/170) andlowest in 0-2 years dog 5.5% (7 /126) was reported. Seroprevalence in male dogs 14/3%(44/306) and in females was 10/ 2% (8/78). The highest infection rate of dogs in the Jaldabakhan village with 48.14% (13/27) and the lowest infection rate of dogs in the Asbfroshanvillage were with 2.8% (2/70). In the study between infection, sex, race, and how the dog keptwas not statistically significant relationship, but with increased age infection level were alsoincreased. Thirty-five dogs 0.5 to 7 years old from various villages of Sarab, and the researchdesign and euthanized in during visceral leishmaniasis studies. They were autopsied andexamined the hearts and lungs (especially pulmonary arteries) for the nematode. Rate of theinfection in the dogs was three cases (8.5%). Only seven adult male of Dirofilaria immitis wascollected from pulmonary artery and one adult male nematode in right ventricular of the dogs.That revealed Dirofilaria immitis occult infection (no present of the microfilariae in the blood)in the dog. The findings of this study Dirofilaria immitis infection in this area need for morecomprehensive review and control pollution will emphasize.
