I recently gave a talk to a group here in Iowa City, emphasizing just how frequently we share microbes. It was a noontime talk over a nice lunch, and of course I discussed how basically we humans are hosts to all kinds of organisms, and analysis of our "extended microbiome" shows that we share not only with each other, but also with a large number of other species. We certainly do this with my particular organism of interest, Staphylococcus aureus. There are many reports in the literature showing where humans have apparently spread their strains of S. aureus to their pets (dogs, cats,…
It's been not even a month since the last paper looking at MRSA in meat, and up pops another one. So far here in the US, we've seen studies in Rhode Island (no MRSA found); Louisiana (MRSA found in beef and pork, but "human" types: USA100 and USA300); the recent Waters et al study sampling in California, Florida, Illinois, Washington DC, and Arizona, finding similar strains (ST8 and ST5, associated with USA300 and USA100, respectively). Now a new study has collected MRSA samples in Detroit, collecting 289 samples from 30 retail stores in the city. For this study, they collected only beef,…
Just received an email from Vector-Borne and Zoonotic Diseases saying that my recent article, The Emergence of Staphylococcus aureus ST398, will be available for free online for the next two weeks. It was submitted roughly a year ago so it's already a bit dated in this quick-moving field, but provides an overview of "livestock-associated" MRSA up to mid-2010 or so--including food-associated MRSA.
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 myself and a handful of excellent graduate & undergrad students. Happily, some of the initial projects are wrapping up, and publications are starting to come out (I'll be blogging about others in the coming days/weeks). One of them was published yesterday in Emerging Infectious Diseases: Livestock-associated…
