Abstract:

The infectious status of echinococcosis in wild rodents was investigated at different areas of Alashankou Port.The wild rodent samples were collected from rural,suburb and urban area of Ala-shankou Port during 2013-2014.Then,pathological sections of liver were prepared and stained with H&E;the genomic DNA of livers and cysts were extracted.Cytochrome C oxidase 1 (Cox1),NADH dehydrogenase subunit 1 (ND1) in Echinococcus mitochondria were amplified from the DNA and sequenced.Results were as follows:eight samples with cyst were found in the process of autopsy,and the positive rate was 2.08%.Ten positive samples were detected positive by PCR,and the positive rate was 2.60%.The analysis of Blast showed that 8 samples of our sequences were clustered with that of Echinococcus sp. (Accession No.JQ 690286.1),and their identities were 85%.The remaining 2 samples of our sequences were clustered with that of Echinococcus multilocularis (Accession NO:AB 720065.1),and their identities were 100%.The results of statitical analysis conveyed us the infection rates of echinococcosis at rural and suburb area were 2.74% and 2.38%,respectively,while no positive sample was detected at urban area.The results presented here demonstrate that the wild rodents at rural area of Ala-shankou Port showed the highest infection rate,and its susceptible host was the Rhombomys opimus.
