Blood samples from 2034 dogs were tested to detect Dirofilaria immitis antigen during three consecutive years (from 1994 to 1996) in Gran Canaria Island, Canary Islands, Spain. The prevalence of heartworm infection was 67.02% in 1994, 58.92% in 1995 and 52.18% in 1996, with a mean prevalence of 58.89%. Heartworm infection was more common in males (56.19%) than in females (43.81 %), in dogs aged between 3 and 6 years old. The distribution of the disease in the different climatic zones was studied. Chronological changes in the dog's prevalence for heartworm infection in the three consecutive years and the role of the epidemiological factors in the changes of the positive rates were evaluated.
在西班牙加那利群岛的大加那利岛，连续三年（1994年至1996年）对2034只犬的血样进行检测，以检测犬恶丝虫抗原。1994年丝虫感染率为67.02%，1995年为58.92%，1996年为52.18%，平均感染率为58.89%。在3至6岁的犬中，雄性丝虫感染（56.19%）比雌性（43.81%）更常见。研究了该病在不同气候区的分布情况。评估了连续三年犬丝虫感染率的时间变化以及流行病学因素在阳性率变化中的作用。
