The health officials in the Unites States reported the first case of a bacteria resistant to even last-resort antibiotics. The detection of this superbug in the nation has caused an alarm in the nation as the spread of this bacteria could pose serious threat to the lives of patients who even get common infections.

Commenting on the arrival of such a superbug in the nation, the director of the United States Centers for Disease Control and Prevention (CDC) Thomas Frieden said, “We risk being in a post-antibiotic world.”

Frieden was referring to the urinary tract infection of a 49-year-old woman from Pennsylvania who had not travelled anywhere prior five months before getting the infection. Speaking at a National Press Club luncheon in Washington D.C., Frieden said that the infection id resistant to colistin which is an antibiotic that is reserved for use against the toughest of bacteria termed “nightmare bacteria, “ Reuters reported.

According to the study which reported the bacteria, the superbug itself was infected with a particular DNA called a plasmid which in turn passed along a gene called mfr-1 which makes it resistant to colistin.

Commenting on the superbug, the researchers from the Walter Reed National Military Medical Centre said, “This) heralds the emergence of truly pan-drug resistant bacteria. To the best of our knowledge, this is the first report of mcr-1 in the USA.”

According to the study, the patient with the infection visited a clinic on April 26 with symptoms of urinary tract infection. It was thence found out that the condition could not be treated with the antibiotics.

A microbiologist and senior lecturer at Harvard Medical School, Dr. Gail Cassell said, “It is dangerous and we would assume it can be spread quickly, even in a hospital environment if it is not well contained.”

The findings of the study was reported on Thursday in a study appearing in Antimicrobial Agents and Chemotherapy, a publication of the American Society for Microbiology.
