目的利用人工合成的PCR随机引物,对本单位培育的HFJ和MIJ近交系大鼠基因组DNA进行扩增,建立HFJ和MIJ大鼠RAPD扩增特征图谱;选择常用近交系大鼠Lewis和F344作为对照品系,观察HFJ和MIJ大鼠与对照品系大鼠的RAPD多态性。方法用酚-氯仿法分... 目的利用人工合成的PCR随机引物,对本单位培育的HFJ和MIJ近交系大鼠基因组DNA进行扩增,建立HFJ和MIJ大鼠RAPD扩增特征图谱;选择常用近交系大鼠Lewis和F344作为对照品系,观察HFJ和MIJ大鼠与对照品系大鼠的RAPD多态性。方法用酚-氯仿法分别提取4个不同品系大鼠的基因组DNA,从60条随机引物中筛选能够得到清晰扩增条带的30条引物,对HFJ和MIJ大鼠DNA进行扩增。再从30条引物中随机选择12条,对4个品系大鼠基因组DNA扩增,并对扩增条带多态性比较分析。结果 30条引物对HFJ和MIJ大鼠DNA进行扩增,均能获得1~7个较清晰条带,除引物O~08外,条带的分子大小均在200~1 100 bp之间,两品系的引物O-08扩增结果,均在2 000 bp以上的近原点处扩增出1条清晰的条带。HFJ和MIJ大鼠品系内个体间和两个品系之间,扩增的结果均完全一致;用12条随机引物对4个品系大鼠同时扩增,HFJ和MIJ大鼠扩增结果一致,与Lewis和F344比较,有5个引物出现差异条带。结论用30条随机引物建立了HFJ和MIJ大鼠RAPD扩增特征性图谱。由于两品系来源于同一对Wistar封闭群大鼠,虽然遗传特性有显著差异,但是在所选30条引物扩增时,未发现多态性。两品系与Lewis和F344之间存在多态性条带。 展开更多

Objective:To determine the presence of Babesia bovis(B.bovis) in large ruminants in southern Punjab and its effect on hematological and serum biochemical profile of host animals.Methods:Blood samples were collected from 144 large ruminants,including 105 cattle and 39 buffaloes,from six districts in southern Punjab including Multan,Layyah,Muzaffar Garh,Bhakar,Bahawalnagar and Vehari.Data on the characteristics of animals and herds were collected through questionnaires.Different blood(hemoglobin,glucose) and serum(ALT,AST,LDH,cholesterol)parameters of calves and cattle were measured and compared between parasite positive and negative samples to demonstrate the effect of B.bovis on the blood and serological profile of infected animals.Results:27 out of 144 animals.from 5 out of 6 sampling districts,produced the541-bp fragment specific for B.bovis.Age of animals(P=0.02).presence of ticks on animals(P=0.04)and presence of ticks on dogs associated with herds(P=0.5) were among the major risk factors involved in the spread of bovine babesiosis in the study area.ALT concentrations were the only serum biochemical values that significantly varied between parasite positive and negative cattle.Conclusions:This study has reported for the first time the presence of B.bovis in large ruminant and the results can lead to the prevention of babesiosis in the region to increase the livestock output. 展开更多
