Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

不同品系小鼠卵母细胞对输卵管在体内滞留产生的反应不同，滞留10min C57BL/6系小鼠卵母细胞死亡率为56.5%，显著高于昆明鼠(47.6%)；自发激活率分别为13.3%和46.0%，C57BL/6系小鼠显著低于昆明鼠。4.hCG后24h体内滞留5min卵母细胞在CZB中培养自发激活率为81.1%，显著低于SrCl_2孤雌激活率(96.4%)；自发激活的卵母细胞有较高的卵裂率(93.2%)和4-cell比率(87.3%)，但囊胚率(18.7%)较低，同卵龄的卵母细胞经SrCl_2孤雌激活囊胚发育率为22.9%，差异不显著。

One ESBLS-producing strains was detected in Pseudomonas aeruginose,Enteric aerogenes and Citrobacter,respectively.
