MRSA and bedbugs?

An ahead-of-print paper in Emerging Infectious Diseases is generating some buzz in the mainstream media. While the findings are interesting, I’m honestly not sure how they got published, being so preliminary. Like many areas, Vancouver, British Columbia has seen a jump in the prevalence of bedbugs. After finding impoverished patients infested with the bugs, researchers…

As Maryn McKenna and others have reported, a paper was released on Friday showing a high percentage of drug-resistant Staphylococcus aureus contaminating raw, retail-available meat products. There has been a lot of media coverage of this finding–so what does the study say, and what are its implications? More after the jump.

One of the reasons I’ve not been blogging as much over the past 2 years or so is that it’s been just insane in the lab. As I was still living off start-up funds and pilot grants, I didn’t have anyone full-time to take care of everything, so all the work has been done by…

MRSA ST398 in US swine

A little over a year ago I put a post up documenting research out of Canada which found methicillin-resistant Staphylococcus aureus (MRSA) in Canadian pigs. This had also been seen in Europe (with a lot of research coming out of the Netherlands). What I didn’t note at the time was that we were gearing up…

Balance is a tricky thing to find in area, and medicine is notorious for its trade-offs. A drug that may make you well in the long run may also have side effects that make taking the medicine difficult. Even drugs that we often think of as typically innocuous, such as antibiotics, can have an enormous…

This is the first of 6 guest posts on infectious causes of chronic disease. By David Massaquoi Is this the Beginning of the end of antibiotic resistant problem or just another scientific false hope of eradicating microorganisms that have co-existed with humans for millions of years? In the days before antibiotics, some researchers saw bacteriophages,…

Early this week, grant application; yesterday and today, IRB and IACUC for another project. But once again, fellow Sbers are keeping me busy reading about stories I’d like to be writing on; see yet again Mike on E. coli O157:H7–everything old is new again; Ed on a new study showing yet again how amazing bacteria…

MDR CA-MRSA in MSM*

Methicillin-resistant Staphylococcus aureus (MRSA) has taken up residence in sport teams, prisons, schools, the military, and even swine. A new article in the Annals of Internal Medicine shows that, at least in Boston and San Francisco, it’s also causing a lot of infections in men who have sex with men; more after the jump.

Over at Evolgen, RPM notes an interesting study in PNAS, looking at antibiotic use and how it serves to drive the emergence and maintenance of antibiotic-resistant strains. The current paradigm for antibiotic use is to prescribe relatively high doses of drugs for a few days to a few weeks (or months, in the case of…

In my field, many things that cause the average man-on-the-street to get a bit squeamish or squicked are rather commonplace. My own studies include two types of bacteria that are carried rectally in humans (and other animals), so I spend an absurd amount of time thinking about, well, shit, and the lifeforms that inhabit it…
