The resistant bacteria of Colistin, the last defense of antibiotics, has been discovered in China recently.
Colistin is an old drug which was introduced in around 1959. It is rarely used because of its effects of injuries to the liver and kidneys. However, since it was the last choice of drug available for the one who is infected by resistant bacteria to a sort of other antibiotics, it seems that this problem become a horrible matter to happen.
Where did all of these come from? Due to the meet stock needed is increased very quickly, many livestock of animals were raised from an unhygienic condition that was habitable for bacteria to develop. Regardless, they decided to feed the animals with a mixture of antibiotic to wipe as many bacteria as they could, and prevent them from being sick. As this process goes on continuously, the bacteria both reproduced and evolved at once as they produced somekind of gene which made the antibiotic harmless. The meat, finally, was eaten by humans containing the resistant bacteria.
In this case, a lot of livestocks in China, gave Colistin to the animals that they unconsciously made our last weapon for complex infections caused by E. coli, Klebsiella, Acinetobacter and similar gut-dwelling organisms to become useless for the bacteria which is resistant. The newly resistant gene itself is known as MCR-1.
Hm. It sounds pretty dreadful, am I wrong?
