摘要

1994年7月至1995年5月以至國立台灣大學附設家畜醫院就診之361頭寵物犬為對象，抽血進行鏡檢下犬心絲蟲幼絲蟲檢查及犬心絲蟲成蟲抗原血清學檢查作為調查流行率之方法。在犬心絲蟲幼絲蟲鏡檢方面：在361頭犬隻共有20頭為陽性，其陽性率為5.5%（20/361），在犬心絲蟲抗原檢查方面：在361頭犬中共有64頭為陽性犬，陽性率為17.7% （64/361）。在全部陽性為例中，以犬心絲蟲幼絲蟲鏡檢及心絲蟲成蟲抗原檢查相互比較結果為：17頭犬隻同時具二項檢查陽性反應（25%，17/ 67），另47頭犬隻只具成蟲抗原陽性的陰性感染（70%，47/67），而有3頭犬隻鏡檢下發現幼絲蟲存在，但成蟲抗原測試為陰性（5%，3/67）。受測犬中有36頭犬隻為年齡小於一歲之幼犬，檢查結果發現這些幼犬百分之九十以上（33/36）無論於幼絲蟲鏡或成蟲抗原檢查都呈陰性反應；若扣除一歲以下幼犬數目，僅計算一歲以上成犬感染率，則陽性率為19.7%（64/325）。在性別方面：無論是在成犬或幼犬其雌雄性別在感染率上並不具差異性；在品種方面則發見大型犬較小型犬有更高的感染率。

Total 361 cases of dogs with owner admitted to National Taiwan University Veterinary Hospital were surveyed for microfilaremia and adult heartworms antigen (Ag) during 1994 July to 1995 May. Among these dogs, 20 of them (5.3%, 20/361) had microfilaremia under microscopic examination. Whereas of heartworm Ag serologicalIy, 64 dogs revealed positive reaction (17.7%, 64/361). In total positive cases (dogs had either serological positive or microfilaremia), 17 dogs presented both microfilaremia and positive serologic results (25%, 17/67), 47 dogs (70%, 47/67) with occult infestation (positive serologic result, negative microfilaremia result). Only three dogs had microfilaremia but negative serologic result (5%, 3/67). In dogs with age younger than 1 year old, 92% (33/36) were either amicrofilaremia nor negative adult heartworm Ag result. However, adult dogs (with age ＞ 1 year old) had higher heartworm infestation rate (19.7%, 64/325) than puppy (with age ＜ 1 year old) (p ＜ 0.05). In genderence, there was no significant difference in susceptibility between male and female dogs. In the present study, we found that large breed dogs were more frequently infected than small breed dogs.
