Over the past century, a huge variety of antibiotics have been developed to treat the plethora of bacterial species that cause human diseases. Some strains of bacteria have evolved into “superbugs” that cannot be killed easily by antibiotics.
Its evolution Every time bacteria are exposed to antibiotics, there is potential for resistance to evolve. The way humans use antibiotics has helped fuel the rise of the superbugs.
New Delhi-Metallo-1 Scientists have warned that this new superbug, called New Delhi-Metallo-1, resistant to antibiotics, has reached Britain and could spread worldwide as nothing is being developed to combat it. The bug was found attached to E.coli bacteria that cause urinary tract and respiratory infections, they say, adding it has “an alarming potential to spread”.
