Pathogenicities of APEC isolates in the neonatal rat meningitis model.

aNegative control for the neonatal rat meningitis model.bPositive control for the neonatal rat meningitis model.cData mean the number of dead rats/total number of rats tested.dData mean the number of rats from which the APEC/ExPEC strain was reisolated/total number of rat survivors.eMean number of E. coli isolates recovered from the blood and CSF of the rat survivors.fValues are not significantly different (P≥0.05 by Fisher's exact test) with the negative control.Pathogenicities of APEC isolates in the neonatal rat meningitis model.a. 本项为新生大鼠脑膜炎模型的阴性对照。 b. 本项为新生大鼠脑膜炎模型的阳性对照。 c. 数据为死亡大鼠数/受试大鼠总数量。 d. 数据代表可分离出禽致病性大肠杆菌（Avian Pathogenic E. coli, APEC）/肠外致病性大肠杆菌（Extraintestinal Pathogenic E. coli, ExPEC）菌株的存活大鼠数/存活大鼠总数量。 e. 数据为存活大鼠血液及脑脊液（cerebrospinal fluid, CSF）中回收的大肠杆菌分离株的平均数量。 f. 各组实验数值与阴性对照组相比，差异无统计学意义（Fisher精确检验，P≥0.05）。 禽致病性大肠杆菌分离株在新生大鼠脑膜炎模型中的致病性。
