Antibiotic Resistant Bacteria Spreads

The last drug has fallen. Bacteria carrying a gene that allows them to resist polymyxins, the antibiotics of last resort for some kinds of infection, have been found in Denmark and China, prompting a global search for the gene.

The discovery means that gram-negative bacteria, which cause common gut, urinary and blood infections in humans, can now become “pan-resistant”, with genes that defeat all antibiotics now available. That will make some infections incurable, unless new kinds of antibiotics are brought to market soon.

Colistin, the most common polymyxin, is a last-resort treatment for infections with bacteria such as E. coli and Klebsiella that resist all other available antibiotics.

In November, Yi-Yun Liu at South China Agricultural University in Guangzhou and colleagues discovered a gene for resistance to colistin in infected livestock, meat and humans. The mcr-1 gene can pass easily between bacteria, and the researchers predicted it could soon go global.

Cook your food well.
I still eat rare steak, but the outside is cooked.
Cooking kills most the gut infectious bacteria.
I don’t eat raw vegetables or fruit unless the outside has been washed well.
Won't cut into any fruit without washing the skin/rind well.
I don’t buy melon slices from the store, you don't know if the fruit was washed before cutting and you don't know where their knife has been.

What bothers my gut is too much vodka and frozen reheated dinners, goes right through the next morning.
