摘要
为了探讨寄生在大熊猫、小熊猫、黑猩猩、白眉长臂猿和4种熊科动物(北极熊、棕熊西藏亚种、狗熊四川亚种和棕熊东北亚种)体内蛔虫的分类地位,测定了核糖体第二内转录间隔区(ITS-2)基因序列,并对这些序列进行同源性分析和采用UPGMA法构建分子系统树。结果表明:寄生在大熊猫、小熊猫和4种熊科动物体内的蛔虫均为贝蛔属蛔虫;寄生在黑猩猩和白眉长臂猿体内的蛔虫为蛔属蛔虫。分析结果提示蛔虫与宿主之间存在协同进化关系。
To clarify the taxonomic status of roundworms from Ailuropoda melanoleuca ,Ailurus fulgens , Pan troglodytes, Hylobates hoolock and 4 species of ursid（Ursus maritirnus , Ursus arctos pruinosus ,Selenartos thibetanus mupinensis and Ursus arctos lasiotus）,the second internal transcribed spacer 2（ITS-2） rDNA was amplified, sequenced and compared with sequences available in GenBank^TM. The phylogenetic trees was constructed based on ITS-2 sequences by UPGMA. The results showed that the roundworms from A. melanoleuca,A, fulgens and 4 species of ursid represent Baylisascaris ,and the roundworms from H. koolocle and P. troglodytes represent Ascaris . The results showed that co evolutionary relationship existed between roundworms and their hosts.
