Health Pandemic Caused By Single Strain of Bacteria – Mystery Solved

Researchers recently discovered that notorious “Black Death” disease or plague can be traced back to a massive proliferation of one single strain of bacteria.

The mystery of the origin of the disease and how it spread so quickly plagued scientists for years.

The disease is believed be caused by the bacterium Yersinia pestis which originated in the 1300s.

Rats living in ships and boats were hosts to flees which carried the disease. The initial reports trace the outbreak back to seaports in Mediterranean cities.

Relying on the mobility of those ships, the plague traveled quickly and left a path of destruction and death in its wake.

By taking samples from multiple grave sites in Europe scientists discovered one single strain of the bacteria was the central cause of the pandemic.
