Bacteria resistant to the most powerful antibiotics ...

British doctors have discovered bacteria that can resist antibiotics to which we turn as a last resort.
Every year in France more than 160 000 patients are hit by infections with antibiotic-resistant bacteria, and 13,000 of them die directly. When all antibiotics fail, doctors are turning to polymyxins (colistin and polymyxin), the powerful antibiotics called "last resort". However, health authorities in Britain have discovered bacteria can resist those antibiotics. MCR-1 gene, which renders bacteria resistant to colistin, has indeed been found in samples of Escherichia coli from human and pork meat as well as samples of Salmonella, UK.
Alert antibiotic-resistance
Following an alert on this antibiotic-resistance launched in China last November, British doctors analyzed 24,000 samples of bacteria and they have discovered the MCR-1 gene in fifteen samples from two human patients but as pigs and poultry.
However, the health authorities want to reassuring part because the identified organisms can be killed with proper cooking. "In addition, all bacteria that we have identified with this gene were susceptible to other antibiotics, known as carbapenems, penicillins family" says Professor Alan Johnson, head of Infection and Antimicrobial Resistance Department of Health Agency British public.
On 17 December, the veterinary authorities of the Netherlands had made the same discovery, the offending gene has been detected in samples of salmonella collected between 2014 and 2015, from Dutch chicken meat and "import turkey."
