Detection of SRV/D shedding in body fluids of cynomolgus macaques and comparison of partial gp70 sequences in SRV/D-T isolates.
We previously reported the isolation of a novel subtype of SRV/D-Tsukuba (SRV/D-T) from two cynomolgus monkeys (Macaca facicularis) in the breeding colony of Tsukuba Primate Research Center (TPRC). We surveyed for SRV/D infection in the TPRC cynomolgus colony using SRV/D-specific PCR primer sets designed based on the entire gag region sequence. The only SRV/D subtype detected in the colony was SRV/D-T with a positive infection rate of 22.4% (n = 49). It has been reported that the mode of transmission of SRV/D is via contact with virus shed in the body fluids. In this report, to investigate the infection route of SRV/D-T in monkeys at TPRC, we performed virus isolation and PCR for detection of the SRV/D genome from peripheral blood mononuclear cells (PBMCs), plasma, saliva, urine, and feces. Virus isolation and PCR detection were positive in plasma, saliva, urine, and fecal samples from all monkeys on which virus was isolated from PBMCs. This suggests that the spread of SRV/D-T infection in TPRC is via contact with virus shed in saliva, urine, and/or feces. Also, comparison of sequences of gp70 on multiple SRV/D-T isolates revealed that there was little intra- and inter-monkey variation, suggesting that SRV/D-T is fairly stable.
