Genome of E.coli bacteria made from stomach of 600-year-old Italian mummy
You must have read or heard about bacteria called E-coli at some time or the other. It comes under the category of deadly bacteria that is found in the digestive tract of human. However, since when it has been living with us, it is not yet known about it. Now researchers have prepared the ancient genome of this bacteria. Researchers at McMaster University have prepared the ancient genome of this bacterium from the gallstones of a 16th-century Italian mummy. The genome contains all the genetic information of an animal.
E.coli does not cause any epidemic, but is known as a food-borne bacteria. These bacteria are present in the intestines in our body and when the body’s immunity starts weakening, they attack. These bacteria mostly harm or make them sick in stressed, immunocompromised individuals.
An epidemic like the Black Death, which killed more than 200 million people, is present in history. But there is no evidence in history about deaths due to E.coli bacteria. Communication Biology Researchers have tried to make 600-year-old E.coli, which can reveal a lot about its evolution, it has been told in the study. For this he has used the body fibers of an Italian mummy.
The team of researchers examined the mummy of a 48-year-old Nobel who died in 1586. The team found that she also had gallstones. Due to this he also suffered from irritation of the gallbladder.
An undergraduate student at McMaster University Told That when we were investigating this, we did not find any evidence that E. coli bacteria were present in this person. We did not find any such physical signs other than an infection like varicella. Nobody knows what it was.
Most species of E.coli do not cause any harm. But there are some strains that can cause life-threatening food poisoning and can also cause blood infections. Also it is adaptable. According to any medicine, it adapts itself and then its effect stops on it.
