This historic image, depicted a prairie dog, Cynomys sp., necropsy being performed at the former Public Health Service's Communicable Disease Center plague laboratory in San Francisco, California. This animal was a member of the Chubbs Park, Chaffee County, Colorado prairie dog colony, during a 1959 complete colonial die off, due to an epizootic plague infection. Plague is caused by the bacterium, Yersinia pestis, and is transmitted from rodent to rodent by infected fleas.
