中文摘要 | 自1995年11月至1996年10月間定期至台北市家畜衛生檢驗所剖檢法定安樂死 流浪犬,結果在解剖的83隻流浪犬中63隻被檢出感染有7種不同種類的寄生蟲,其中5種 屬於人畜共通寄生蟲。寄生蟲感染率平均為76%,雄性犬的感染率(80%)與雌性犬的感 染率(72%)間並未呈現統計學上之差異(p>0.05)。犬鉤蟲(Ancylostoma caninum)和犬 條蟲(Dipylidium caninum)的感染率同為34%最高,其次為犬心絲蟲(Dirofilaria immitis) 的28%、犬蛔蟲(Toxocara canis)的15%、巴貝西蟲(Babesia sp)的8%,犬鞭蟲(Trichuris vulpis)和聯同形球蟲(Isospora sp)的感染率最低,同為1%。在感染蠕蟲成蟲數方面,每 隻犬平均感染犬蛔蟲、犬鉤蟲、犬條蟲、犬心絲蟲成蟲數位次為5、14、4及9條。感染一 種寄生蟲的犬隻佔全部陽性犬隻的56%;感染二種的佔29%;感染三種的佔13%;感染四 種的佔3%。受寄生蟲感染犬隻(n=63)的白血球數(14.8�e10 ╱min )除明顯較未感染 寄生蟲的犬隻(n=18)(8.9�e10 ╱min )值高(p<0.05)外,受寄生蟲感染犬隻的嗜酸 性白血球百分比(8%)亦明顯較未受寄生蟲感染犬隻(2%)高(p<0.05)。而不論是受寄 生蟲感染或未受寄生蟲感染犬隻的紅血球數或血紅素值皆較正常值低,故對於流浪犬是否因 為體質差,較易感染更多人畜共通疾病進而造成更嚴重的公共衛生問題,亟需加以注意。 |
英文摘要 | To assess the prevalence of parasitic infections among stray dogs in Taipei city, a total of 83 dogs obtained from Taipei Municipal Institute for Animal Health were necropsied from November 1995 to October 1996. Haematological examinations were also undertaken. Seven species of parasites were found, of which five were zoonotic. The overall prevalence of parasitic infections was 76% and there was no significant difference between males (80%) and females (72%) (p > 0.05). The following infection rates were obtained: 34% for A. caninum and D. caninum, 28% for D. immitis, 15% for T. canis, 8% for Babesia sp, and 1% for Trichuris sp and lsospora sp. The average numbers of adult worms per dog were 5 for T. canis, 14 for A. caninum, 4 for D. caninum and 9 for D. immitis. Out of the 68 infected dogs, 35 had 1 species of parasites, 18 had 2 species, 8 had 3 species and 2 had 4 species. Both the lymphocyte counts and percentage of eosinophils were significantly different between infected (14.8 �e 10 /mm ; 8%) and uninfected (8.9 �e 10 /mm ; 2%) dogs ( p < 0.05). Erythrocyte counts and hemoglobin values among the stray dogs were lower than those seen in normal dogs indicating their reduced nutritional status, thus may become a public health problem. |
