Mutational colistin resistance in CPE is the clear and present danger, not plasmid-mediated mcr genes

There has been a lot of concern in scientific journals and the mainstream media about colistin resistance in Enterobacteriaceae caused by plasmid-mediated resistance genes (the mcr genes). However, an article published today by our group suggests that mutational colistin resistance rather than plasmid-mediated mcr genes is a more pressing clinical threat.

The antibiotic course has had its day?

Schermafbeelding 2017-07-27 om 10.19.00

In a recent BMJ article, Llewelyn et al. argue that the old dogma of completing a prescribed course of antibiotics to prevent antibiotic-resistance is a myth, not based on evidence.  Actually the opposite, namely taking antibiotics for longer than necessary, increases the risk of resistance.

While I love breaking down old dogmas  (we actually had a poll on this topic some time back), many of today’s papers in the Netherlands (and I am pretty sure elsewhere, too) misinterpret the study, by slaughtering the message to patients to “always complete the full prescription”.  One of the Netherlands most influential newspapers the Volkskrant, already wrote: “Finishing antibiotic course? Nonsense.”

Going for GNBSI

We’ll be publishing the results of the vote on whether or not we can halve HA-GNBSI by 2021 later this week. Right now, it looks like Martin is heading for a comfortable, if somewhat depressing victory (“No, we can’t halve GNBSI by 2021”) but there’s still time to ride a wave of positivity and vote with me that “Yes, we can halve GNBSI by 2021”. So, I thought that now would be an appropriate time to review the recent JHI paper that both Martin and I referred to, providing some enhanced epidemiological data on E. coli BSIs in England.

KPC Casanova carbapenemase

The risk of interspecies transmission of carbapenemase genes is a real concern. We can barely get our heads around many different types of carbapenemase in a whole host of Gram-negative bacteria (compare the relative simplicity of methicillin resistance in S. aureus: a single gene, in a single species). Throw in interspecies horizontal transmission of carbapenemases and things get really tricky! Do we implement different control strategies to try to interrupt the transmission of carbapenemases (in contrast to the organisms themselves)? Could you have a multispecies outbreak of a carbapenemase on your hands and not even realise it?

Halving GNBSI

gnbsi-halved

The Department of Health announced last week their intention to halve the rate of E. coli BSI by 2020. Whilst this is a move that should be embraced, it will be an enormous challenge to achieve. The reduction that has been delivered with MRSA BSI could be seen as a model for success (and I suspect that if you were a politician, you would see it this way). However, it is vital to recognise that E. coli BSI and, more broadly, Gram-negative BSI (GNBSI) are not the same as MRSA BSI, and will require a different reduction strategy.

Poultry production and antimicrobial resistance in India

Take a look at these three stories on intensive poultry production and antimicrobial resistance in India published yesterday on the Bloomberg website. In accordance with what the movie industry does, these articles should be accompanied by a warning: “These articles contains scenes that some readers may find disturbing”. As the editor of the articles said in an email to colleagues that forwarded it to me: “I think you’ll agree that these are important stories and deserve attention (and hopefully a response from the appropriate authorities and the community).” Obviously, I do agree.

We need to EMBRACE engineers in the fight against HCAI and AMR

Embrace logo ok

I attended the first EMBRACE seminar today at Imperial College London. EMBRACE (Engineering, Medicine, Natural Sciences and Physical Sciences Bridging Research in Antimicrobial resistance: Collaboration and Exchange) is a gap-bridging collaborative aiming to bring together Engineers, Scientists, Doctors, and others to find new ways to address AMR and tackle HCAI. I thought I’d share some of my highlights from the seminar.
