*cDNA was synthesized from bat samples obtained after experimental infection (second passage of the group 2d coronavirus in Leschenault rousette bats). Values are copies per milligram. Virus load was quantified by real-time PCR. RT-PCR,reverse transcription–PCR; –, virus RNA not detected; +, virus RNA detected; ND, not detected by real-time PCR in RT-PCR–positive samples.
†Result of nested PCR.
