摘要

A reverse transcription and polymerase chain reaction (PCR) method was developed and used to detect enterotropic mouse hepatitis virus (MHV) in faeces. A nested set of primers for PCR was located in the polymerase region of the MHV genome. The assaywas used to follow the time course of enterotropic MHV excretion in mice after oronasal inoculation with the virus. The assay detected MHV genome excretion in all mice beginning on day 3 through day 21 after inoculation. No MHV genome was detected in inoculated mice on or after day 27 following inoculation. It is concluded that reverse transcription and PCR are useful for enterotropic MHV detection.
