"Nature": Rewrite the history of the birth of "super bacteria"!
Time of Update: 2022-01-25
By comparing the number of mutations in different strains of MRSA, the research team speculates that mecC-MRSA appeared in hedgehogs about 200 years ago, long before the birth of methicillin (1959) .
These naturally secreted antibiotics acted by natural selection, resulting in the coexistence of resistant mecC-MRSA with the fungus on hedgehog skin .
