In Race Between Humans and Bacteria, My Money’s on the Bacteria

From a WHO interview with a top immunologist on the subject of super-bugs, NDM1, & antimicrobial resistance: [-]

Q: What’s special about this new type of resistance labelled as NDM1?

A: NDM1 is an enzyme that confers resistance to one of the most potent classes of antibiotics, known as carbapenems, but what has been observed is different in many ways to what we have seen to date. This new resistance pattern has been reported in many different types of bacteria compared to previously and at least one in 10 of these NDM1-containing strains appears to be pan-resistant, which means that there is no known antibiotic that can treat it. A second concern is that there is no significant new drug development for antimicrobials. Third, this particular resistance pattern is governed by a set of genes that can move easily from one bacterium to another. Fourth, NDM1 has been found in the most commonly encountered bacterium in the human population, E. coli, which is the most common cause of bladder and kidney infections. A further concern is that of the two drugs potentially capable of treating an infection due to one of these new multiresistant strains, one of them, colistin, causes toxic effects to the kidney in about a third of people.

Q: Is this the doomsday scenario of a world without antibiotics?

A: Unfortunately yes, with these new multiresistant NDM1-containing strains and their potential for worldwide spread. Doctors will face a terrible dilemma when a pregnant woman develops a kidney infection that spills over into the bloodstream with a pan-resistant strain containing NDM1 and there are no treatment options. We are essentially back to an era with no antibiotics. [Emphasis mine]
