Black plague

in 14th-century Europe, the victims of the black plague had bleeding below the skin (subcutaneous haemorrhage) which made darkened ( blackened ) their bodies. Black plague can lead to black death characterised by gangrene of the fingers, toes, and nose. Black plague is caused by a bacterium (yersinia pestis) which is transmitted to humans from infected rats by the oriental rat flea.
