wild type strain

The recombinant strain also had lower adhesiveness(P>0.05)and significantly lower relative invasiveness to the HeLa cells than its wild type strain(P<0.05).

细胞试验表明重组菌对细胞的黏附力和相对侵袭力均有不同程度的降低，而相对侵袭力与野生型菌株具有显著性差异（P<0.05）；

Pakistan is affected by nationwide transmission of WPV1, and is the location of the only wild poliovirus type 3 (WPV3) case in Asia in 2011 (a strain on the verge of elimination on the continent).

巴基斯坦全国受到1型野生脊灰病毒传播的影响，并且是2011年在亚洲出现唯一一例3型野生脊灰病毒(在亚洲已濒临消除的一个毒株)病例的地方。

Besides, the strain is wild type with very clear genetic background, which is fit for genetic improvement and is hopeful to improve the capability of disposing the organic waste gas greatly.

此外，该菌株为野生型，遗传背景非常清晰，适于进行遗传改良，有望大幅度提高对有机废气的处理能力。
