Bacteria resistant to the strongest antibiotic colistin found in China finally spared to other countries
"Colistin"Is an antibiotic with a high bactericidal action against Escherichia coli and gram negative bacteria and is known as a drug that can be regarded as the" final fort "as a last resort to infections in which existing drugs do not work. However, it was pointed out that the bacterium having the colistin resistance was discovered in China in November 2015 and it is impossible to prevent the worldwide spread of colistin-resistant bacteria unless limiting the mass use of colistin, but even in the UK Bacteria with colistin resistance were discovered.

Bacteria with colistin resistance were first discovered in China's pig farm. This bacterium is also called "superbug (Super Bug)" because it is resistant to the colistin that the doctor will rely on when any antibiotic is ineffective. In addition, superbug shows "colistin resistance"MCR-1It has been confirmed to have the gene "and I know that it has strong contagious abilities.
The occurrence of super bug is thought to be caused by the excessive use of colistin-containing antibiotics as domestic animal infection prevention in China, and it is thought that it is caused by China, which is the leading producer of pork and chicken in the world The researchers pointed out that super-bugs and MCR-1 are inevitable to spread worldwide unless limiting the administration of large amounts of colistin in.
Meanwhile, in the UKAnimal and Plant Health AgencyAnnounced that it has found 15 superstrings that are resistant to colistin from among 24,000 bacterial samples that have been collected in the UK. A British doctor predicted that it would take three years before China's superbugs spread to the UK, and superbugs may be rapidly spreading all over the world beyond imagination.
Dr. Alan Johnson of the United Kingdom Public Health Service stated, "I think that super bugs themselves can be sterilized by cooking and that the risk of public health damage is very low." However, the MCR-1 gene possessed by the superbug may also be taken up by other bacteria, especially in combination with other genes that are resistant to antibiotics to counteract infection control measures by antibiotics There is also a view that fears the worst situation that it will be done.
