[A transplantable myeloid hamster leukemia with high peripheral leukocyte counts and C-particles. I. Transplantation...

In this article is reported a generalized leukemia of the myeloproliferative system of golden hamsters capable of cellular transmission. Cellfree transmissions to 83 golden hamsters after a 6-month latency period, have so far yielded the same result in three cases. After cellular transplantation leukocyte counts of 180,000 on the average occured abruptly in the end-phase of the disease. Latencies were between 4 and 10 days. Electronmicroscopically, oncorna-viruses were demonstrated in hamsters inoculated with either the cellular or the cellfree preparation that bear close resemblance to the murine C-particles.
