Vampire Microbe Loves Human Blood [Science]

Friends, it is Staphylococcus aureus . Staphylococcus aureus, listed here are some victims. You almost certainly already knew each other. In the end, the bacteria-origin of the MRSA superbug-lives inside the nasal cavity of one third of all humans. Now scientists know why.

They like human blood chiefly other forms of animal blood. Scientists have found that the bacteria prefer human hemoglobin, that is responsible of carrying oxygen through vertebrates. These microbes attach to this protein to suck its iron and other nutrients, and it just happens that they bind perfectly and easily with our version of hemoglobin.

In fact, they seem to prefer different variants of hemoglobin among humans, which might explain why some people suffer repeated infections and others don’t, in keeping with lead researcher Dr. Eric Skaar, from Vanderbilt University Medical Center in Nashville, Tennessee, US:

A big question in staph biology is: why do a little people continuously get infected or suffer very serious staph infections, while other folks do not? Variations in hemoglobin could contribute.

According to the study, other bacteria also seem to prefer human blood to any other vertebrate blood, that’s why I insist in exchanging mine for alcohol- and kerosene-based liquids. [ Cell Host Microbe via The clicking Association ]
