AP, Phil. Inquirer, etc: Tale of DNA in Europe’s E.coli outbreak
Tuesday, June 14th, 2011We all have, and I’d expect that most readers of this site already know this, thriving E. coli infections. That is, if infection can be stretched to mean occupation by billions of happily coexisting microbes in our gut, or on our skin, and elsewhere. E. coli are natural and perhaps necessary parts of the collective us. And as any human population has a few psychopaths, some strains of this ubiquitous microbe run amok in us secreting toxins and sending us skidding into profound, and on occasion lethal, kidney failure or other severe illness.
News coverage of the cases in Germany have inevitably focussed on the public health campaign to chase the culprit to its origin – bean sprouts are pretty nearly convicted. Also getting intense coverage have been the economic and casualty tolls, along with strategies to treat infections once they are identified.
Some also look at this particular vicious strain itself by delving into its evolutionary history and into the peculiar genetic attributes that give it a wicked punch. So, to get to ksjtracker’s writ …
A few that have a focussed science angle:
- AP – Maria Cheng: Scientists probe DNA of E. coli for outbreak clues ; She doesn’t use the term lateral gene transfer, but the story refers to genes swapped among E. coli strains and that sounds to be the same thing. And the result, it says here: This strain sticks more to the gut wall than most, and reproduces faster. Perhaps eight distinct gene variants lend it resistance to antibiotics too. I am puzzled that it says “narrowing down where the ne E. coli came from” is key to reducing risk of further epidemics. One wonders what health officers could do upon learning this strain first arose in some specific district.
- Philadelphia Inquirer/Planet of the Apes Column – Faye Flam: One Nasty Evolver ; Flam gives us the full stomach-churning description how this strain does its dirty work, how it explodes into the billions after only a few dozen cells set up camp (translation: a lowinfectious dose is all it takes), clumping and oozing the Chiga toxin that “massacres blood cells and eventually destroys the kidneys.” Fiendishly, the buggers ramp up their poison production when under assault by antibiotics – sometimes thus hastening death when doctors start trying to prevent it. Suspected, but still unknown for sure, she reports, is what if anything in recent human farming or industrial practice encouraged its rise.
- Deccan Chronicle: No E. coli in India, thanks to cow dung ; The hed means of course no E. coli sicknesses. The story reminds one a bit of the hygiene hypothesis that seeks to explain rises in allergies and perhaps asthma as a consequence of children growing up in such clean circumstances their unchallenged immune systems don’t develop properly. Thisunbylined story from India bears checking. It asserts, after consultation with a German physician working in India, that with all the cow dung in the streets and even used as house plaster in India, the majority of residents of India are exposed to so much bovine-borne E. coli that their systems scoff at any and all variants.
- BBC – Eleanor Bradford: Glasgow University microchip “speeds up DNA analysis’; The recent E. coli outbreak soon had the new gadgetry in action.
- Wall Street Journal (Editorial): Europe’s Organic Food Scare / Bart Simpson as chief safety technologist ; First of all the appropriate Simpson to evoke in this context is idiot Homer, not his son Bart. And second this thing piles on to organic farming as though that explicitly is the problem even though, as the piece itself says, one cannot grow much without having some kind of E. coli involved. But it makes a solid point about irradiation – with gamma rays or electron beams – and phobias about such practice as one reason this tactic for reducing pathogens in what we eat is not used more often.
- HealthDay – Amanda Gardner: Deadly E. Coli Strain in Europe Should Serve as Warning, Experts Say ;
Generally, the science of why most E. coli are our friends – and some are decidedly – not is taking a back seat as a news topic to finger pointing and atttention to straightforward public health work. That latter is seen in an AP story from Kirsten Grieshaber and David Rising that declared in its lede “simple detective work trumped science..” in the hunt, etc. Actually, much of science is itself simple detective work (information plus logic).
But reporters have had plenty of press releases and other direct communicaiton from research oriented institutes to goad some science out of them:
Grist for the Mill:
Nat’l Science Foundation/Live Science – Marlene Cimons (yes, the former LATimes reporter): E. coli Offers Insight to Evolution ; Bioniche Life Sciences Inc Press Release (on vaccine for E. coli O157) ; Univ. of Southampton Press Release (on copper as an E. coli preventive); BGI (Beijing genomics institute) Press Release on analysis of the O104 strain ; Virginia Tech Press Release (on lab studies of the culprit strain);
Dept of Whattaya call a site like THIS?
The borders among old fashioned (if with new technology) journalistic news writing, public service announcements, p.r., blogging, the sheer commercial opportunism of inf0-ads, and gov’t or non-profit or corporate outreach are getting blurrier all the time.
The search for stories turned up one site that is hard to peg on the news scale, the responsibility scale, the p.r. scale…. Its parent organization is something called WOW NEW MEDIA, based in Spain. It says its goal is to generate and maintain profitable online businesses and strong brand equities. Whatever that means. I think it means it aims to make money off ads, which hardly sets it apart from a zillion other sites. The specific site that popped up during the search for news stories is called E. coli O104:H4 – the ongoing Eshcerichia coli 0104:H4 bacterial outbreak. That almost looks composed explicitly to turn up high on a key-word search. Oh. No almost about it. It has informational items that look loosely rewritten from news stories. And lots and lots of ads. I cannot say it is reckless. But the writing is a bit slap dash. Now, old timey newspaper and cable TV news moguls have, or had, a business model – provide news etc. in order to sell ads. That was cynical enough. But I am unsure what to call the verbiage around which these ads at E. coli 0104:H4 are wrapped.
