Abstract

Feline calicivirus (FCV) strains isolated from feces (E-FCV) were compared with FCV strains of respiratory origin (R-FCV). All strains were shown to be labile at pH 3.0. All strains except one strain of E-FCV were found to be sensitive to the action of trypsin. When exposed to bile salt (deoxycholic acid sodium salt), all R-FCV strains were markedly inactivated, but none of the E-FCV strains was inactivated. It was possible to select bile-resistant substrains from a bile-sensitive strain.

摘要

将从粪便中分离出的猫杯状病毒(FCV)毒株(E-FCV)与呼吸道来源的FCV毒株(R-FCV)进行了比较。所有毒株在pH 3.0时均显示不稳定。除一株E-FCV毒株外,所有毒株均对胰蛋白酶的作用敏感。当暴露于胆盐(脱氧胆酸钠盐)时,所有R-FCV毒株均被显著灭活,但E-FCV毒株均未被灭活。从一株对胆汁敏感的毒株中有可能筛选出耐胆汁的亚毒株。
