The stability of hog cholera virus through five freeze-thaw cycles in the presence and absence of dimethyl sulfoxide was studied. In the absence of dimethyl sulfoxide the hog cholera virus titer was reduced 52% to 91% following successive freezing and thawing cycles. However, when dimethyl sulfoxide was added to the viral suspension the virus titer appeared to remain the same after the same number of freezing and thawing cycles.
研究了猪霍乱病毒在有无二甲基亚砜存在的情况下经五次冻融循环后的稳定性。在无二甲基亚砜的情况下,连续冻融循环后猪霍乱病毒滴度降低了52%至91%。然而,当向病毒悬液中添加二甲基亚砜时,在相同次数的冻融循环后病毒滴度似乎保持不变。
