The effects of incubation temperature on virus growth and mortality patterns were studied in antibody-free chicken eggs inoculated with the B1 strain of Newcastle disease virus. Embryo mortality patterns did not differ much between 37, 39, and 41 C of incubation, although virus growth curves were higher at 39 C and 41 C than at 37 C. Below 35 C, embryo mortality was delayed, although from 48 hours after incubation the virus growth curves were similar to those at 37 C. In eggs with and without maternal antibody, virus titers were maximum 48 hours after incubation, although slightly higher in antibody-free eggs than in eggs with antibody whether the eggs were alive or dead. Eggs with maternal antibody had delayed mortality patterns.
在接种新城疫病毒B1株的无抗体鸡胚中研究了孵化温度对病毒生长和死亡模式的影响。尽管在39℃和41℃时病毒生长曲线高于37℃，但在37℃、39℃和41℃孵化时胚胎死亡模式差异不大。在35℃以下，胚胎死亡延迟，尽管在孵化48小时后病毒生长曲线与37℃时相似。在有和没有母源抗体的鸡蛋中，病毒滴度在孵化后48小时最高，尽管无论鸡蛋是活是死，无抗体鸡蛋中的病毒滴度略高于有抗体鸡蛋。有母源抗体的鸡蛋死亡模式延迟。
