Atypical Typhus

This is the third of 16¬†student posts, guest-authored by Mary Egan. Murine typhus has been in the news recently in Austin, TX, where in May of this year, two people were found to be positive and one died.¬† This rings a number of alarm bells for me, since I live in Texas, and specifically in…

While “flesh-eating infections” caused by the group A streptococcus (Streptococcus pyogenes) may grab more headlines today, one hundred and fifty years ago, the best known and most dreaded form of streptococcal infection was scarlet fever. Simply hearing the name of this disease, and knowing that it was present in the community, was enough to strike…

I left off yesterday with the initial discovery of “Vero toxin,” a toxin produced by E. coli (also called “Shiga toxin” or “Shiga-like toxin”). Though this may initially seem unconnected to hemolytic uremic syndrome (HUS), the discovery of this cytotoxin paved the way for a clearer understanding of the etiology of this syndrome, as well…

As I mentioned yesterday, the epidemiology of hemolytic uremic syndrome (HUS) was murky for several decades after it was first defined in the literature in 1955. In the ensuing decades, HUS was associated with a number of infectious agents, leading to the general belief that it was a “multifactorial disease”–one that had components of genetics…

Via H5N1, German officials are calling it for sprouts: Germany on Friday blamed sprouts for a bacteria outbreak that has left at least 30 dead and some 3,000 ill, and cost farmers across Europe hundreds of millions in lost sales. “It’s the sprouts,” Reinhard Burger, the president of the Robert Koch Institute, Germany’s national disease…

Maryn McKenna has a great update today on the E. coli situation, looking at where we are as far as unanswered questions about the outbreak and the strain. It’s been a messy day; more evidence seems to point to the sprout farm, but CIDRAP also notes that another contaminated cucumber was found in the compost…

Well, Sunday the said we’d have some results on the sprout tests for E. coli O104:H4. Well, so far the results are negative. The 1st tests from a north German farm suspected of being the source of an _E. coli_ [O104:H4] outbreak are negative, officials say. Of 40 samples from the farm being examined, they…

The E. coli story is moving quickly. A news report out today suggests that sprouts might be the culprit (though it should be emphasized that the outbreak strain hasn’t been isolated from these vegetables yet): Mr Lindemann said epidemiological studies all seemed to point to the plant nursery in Uelzen in the state of Lower…

Mike has has a great new post up looking at some molecular analyses of the current European outbreak strain. For anyone who hasn’t been paying close attention to what’s happening across the pond, there’s an ongoing outbreak of enterohemorrhagic E. coli (EHEC)–the type of E. coli that includes O157:H7, which has been associated with outbreaks…

Bubonic Plague in America

At the new blog Puff the Mutant Dragon, there’s a great pair of posts looking at the history of plague, with a focus on outbreaks that have occurred here in the US. Bubonic Plague in America, Part I: LA Outbreak Bubonic Plague in America, Part II: Undercover Science I’ll also link them in my Black…
