A new disease of rabbits is described. Following an acute febrile course, animals die or recover by the 11th day postinoculation. The characteristic pathologic finding is multifocal myocardial degeneration and necrosis. The disease can be transmitted by various routes with tissue filtrates or with infectious sera diluted to 10(-6) and passed through 0.1(More)
The prevention and control of mousepox begins with investigators being aware of the disease's existence and its serious nature for users of mice and mouse tissues. Every institution must include as part of its management policy, provisions to ascertain that mice and mouse tissues entering its facilities are free of ectromelia virus. Policy must encompass(More)
BACKGROUND The diagnosis of prostate cancer is dependent on histologic confirmation in biopsy core tissues. The biopsy procedure is invasive, puts the patient at risk for complications, and is subject to significant sampling errors. An epigenetic test that uses methylation-specific polymerase chain reaction to determine the epigenetic status of the prostate(More)
Twenty-eight guinea pigs from nine episodes of subclinical scurvy had diarrhea, weight loss and dehydration. The classical signs of scurvy were not seen. Microscopically the epiphyses were attenutated and irregular. The amount of osteoid was less than normal. Many guinea pigs had acute enteritis. In some there were many hemosiderin-laden macrophages in the(More)
Rabbit Coronavirus (RbCV) infection was divided into two phases based upon day of death and pathologic findings. During the acute phase (days 2-5) heart weights (HW) and heart weight-to-body weight (HW/BW) ratios were increased with striking dilation of the right ventricle. These changes as well as increased dilation of the left ventricle were especially(More)
A rabbit model for coronavirus-induced dilated cardiomyopathy is described. Acute rabbit coronavirus infection results in virus-induced myocarditis and congestive heart failure. Of the survivors of rabbit coronavirus infection, 41% had increased heart weight and heart weight-to-body weight ratios, biventricular dilation, myocyte hypertrophy, myocardial(More)
In a model for virus-induced myocarditis and congestive heart failure, rabbit coronavirus infection was divided into acute (days 2-5) and subacute (days 6-12) phases on the basis of day of death and pathologic findings. During the acute phase, the principal histologic lesions were degeneration and necrosis of myocytes, myocytolysis, interstitial edema, and(More)
Rabbit coronavirus (RbCV) was apparently first encountered in 1961 when Scandinavian investigators observed occasional mortality in rabbits used to propagate the Nichols strain of Treponema pallidum. Mortality rates reached 50 percent by 1968 and 75 percent by 1970. Contaminated samples of T. pallidum were brought to the Johns Hopkins University School of(More)
