This deadly bacterium is found in each person's skin

Staphilloccus epidermidis, a close relative of MRSA, known as a cause of dangerous infections for life after surgery.

Scientists took samples from patients who were infected with knee surgery and compared them with the skin of healthy volunteers.

They compared the whole genome of bacteria from the seized samples and thus identified 61 that otherwise allows the harmless bacteria from the skin to cause the disease from which one can die.

Scientists hope to find out why some species of bacteria under certain conditions cause disease, which would in the future allow for identification of which patients are most at risk of infection outbreak after surgery.

A small number of healthy people carried bacteria into one of the deadliest forms, unaware of it.

The genes that cause mortality help bacteria grow in blood and avoid immune systems and become resistant to antibiotics, writes the magazine “Communications Nature “.

The infection of the sttilokoc is the cause of the death of one third of the population in Great Britain.

Sam Shepherd, director of bio-informatics at Milner Centre, who conducted the study, says bacteria are so popular that they can change the mutual exchange of genes.
