Nowadays, highly resistant strains was found in the British river, these bacteria can be "immune" to antibiotics, scientists warned that this need to be highly valued, this may lead to the emergence of super-resistant bacteria.
At present, scientists warned that high resistance strains was found in the downstream sewage treatment plant of Softway River, United Kingdom Coventry. It may trigger the threat of potential super bacteria.
It is reported that high-resistance bacteria are detected when British Warwick University experts collect samples in the sewage treatment plant, which are E. coli strains in human excrement, it can produce extended-spectrum β-lactamase (ESBLs) This enzyme can destroy many antibiotics, including penicillin.
Extended spectrum β-lactamase infection is more harmful, because the treatment is very limited, in serious cases it need to inject drugs. Prof. Elizabeth Wellington, a lecturer in environmental microbiology at the University of Warwick, and colleagues studied and collected samples from the upstream and downstream of the Softway River.
They found that drug-resistant bacteria are important for the use of antibiotics for the treatment of diseases, including meningitis, sepsis, iatrogenic infections. At the same time, they found that drug resistance of E. coli in sewage treatment plant upstream is 7 times than downstream.
This study shows that drug-resistant bacteria are gradually spreading, because this blaCTX-M-15 genotype bacteria can adapt to the living environment. The researchers pointed out that the water quality control and high levels of sewage treatment are needed currently, which will stop the risk of drug-resistant bacteria breeding in the environment, inhibit the "super bacteria" effectively.
Professor Wellington said: "If you stir the water with drug-resistant bacteria, then have 5mL of this water, you will face the risk of suffering from gastroenteritis, which will make you seriously ill. If the drug-resistant bacterial population sojourn in your digestion system, after the urinary tract infection, it will leave the body through the excretion, which will expand the scope of the spread." The latest research is published in journal "antibacterial chemotherapy".
