Effect of pasteurization and heat treatment on bovine leukemia virus.

摘要: Four sheep inoculated with mixtures of bovine leukemia virus (BLV) and milk that was treated by a simulated high-temperature short-time pasteurization procedure did not become infected BLV or develop tumor. unpasteurized BLV-mil became 3 died tumor at 15, 21, 27 months, respectively, after inoculation. Fluid from BLV-infected cell culture heated to 56, 60, 65, 73 C for 1/2 minute 1 (in separate trials) transferred noninfected cells. Culture fluid 60 higher infect the
