What Is Shigella Dysenteriae?

Shigella dysenteriae is a species of the rod-shaped, gram-negative, and non-motile bacteria that can cause bacillary dysentery — the most severe form of shigellosis.

History of Shigella Dysenteriae

Shigella dysenteriae is named after the Japanese physician Kiyoshi Shiga, who researched the cause of dysentery in the late 19th century when Japan was suffering from dysentery outbreaks.

It all started in 1892 when Shiga joined the Tokyo Imperial University School of Medicine to attend lectures by Dr. Shibasaburo Kitasato — an expert physician and bacteriologist.

He was so impressed with Dr. Kitasato’s intellect and confidence that after graduating; he applied to be a research assistant for him at the Institute for Infectious Diseases.

In 1897, Shiga started studying dysentery outbreaks, which were detrimental to the Japanese people and occurred often in the late 19th century.

The epidemic of 1897 in Japan affected more than 91,000 people with a mortality rate of over 20%.

Shiga studied 32 dysentery patients and used Koch’s Postulates to successfully identify the bacterium causing the disease, which was named shigella dysenteriae.

He found out that dysenteriae is responsible for bacillary dysentery (the most severe form of shigellosis).

From there on, he dedicated the rest of his life to studying the bacterium and working tirelessly to find a vaccine so that he could end the suffering in his country.

Symptoms of Diseases Caused By Shigella Dysenteriae

Dysenteriae can lead to bacillary dysentery, which has the following symptoms:

  • Fever
  • Stomach pain
  • Nausea and vomiting
  • Diarrhea with belly cramps
  • Blood or mucus in the diarrhea

Although symptoms of bacillary dysentery last for only 4 to 8 days in mild cases, they can last anywhere from 3 to 6 weeks in more severe cases.
