|Food poisoning lingers
The effects of a single bout of food poisoning can cause health problems even 20 years later.

It's a dirty little secret ...: E. coli and certain other foodborne illnesses can sometimes trigger serious health problems* months or years after patients survived that initial bout. ...
"Folks often assume once you're over the acute illness, that's it, you're back to normal and that's the end of it," said Dr. Robert Tauxe of the [CDC]. The long-term consequences are "an important but relatively poorly documented, poorly studied area of foodborne illness."
*high blood pressure, kidney damage, even full kidney failure striking 10 to 20 years later in people who survived severe E. coli infection as children, arthritis after a bout of salmonella or shigella, and a mysterious paralysis that can attack people who just had mild symptoms of campylobacter.
Maybe someday they'll start making the connection. What do you think?
|Knowing What We Know (here) about bacteria like E. Coli transforming into L-Forms under the assault of beta-lactams, you have to wonder if those treated with various forms of penicillin are the ones more likely to have had trouble in later years. I assume the study itself used hospital created records of the food poisoning cases (text mention Hospitalized). Would be safe to assume anyone who made it to the hospital was given some sort of ABX.
The rest, as they say, is history.
Also, as they say, this requires further study!
Finally, is there anyone on the planet who has NOT had some food poisoning bout at one time or another, even if they did not realize it at the time? From there the patient subsets branch off for those treated and those not treated, and further branching to various E. Coli that might have caused the infection.
|Along the same lines... but 10 degrees off...
My opinion: We are using a protocol that will make our immune systems fit to fight off these bacterium, but without the understanding that we have an epidemic of immune system dysfunction, these scientists aren't going to come to the right conclusions about what is happening here.
Epidemic superbug strains evolved from one bacterium: study

CHICAGO (AFP) - The drug-resistant "superbugs" that have cut a swathe through day care centers, schools, locker rooms and prisons across the United States in the last five years stem from one rapidly evolving bacterium, US scientists said Monday.
Scientists studying the genetic make-up of these bugs, which are resistant to almost all antibiotics, say they are nearly identical clones that have emerged from a single bacterial strain, which they have dubbed USA300.
"The USA300 group of strains appears to have extraordinary transmissibility and fitness," said Frank DeLeo, a researcher with the National Institute of Allergy and Infectious Diseases (NIAID) in Hamilton, Montana.
"We anticipate that new USA300 derivatives will emerge within the next several years and that these strains will have a wide range of disease-causing potential."
Most drug-resistant staph infections cause soft-tissue infections such as boils that are readily treatable, but a skin infection can become a deadly pneumonia or blood or bone infection in a matter of days if the patient doesn't get the right drugs.
What's particularly worrying to health authorities is that the MRSA infections, (methicillin-resistant Staphylococcus aureus) have spread beyond their traditional hospital setting, seeding an epidemic in the wider community.
The NIAID scientists studied the DNA of 10 patient samples of the USA300 bacterium taken from individuals treated at different US locations between 2002 and 2005. They compared the genetic sequences of the bugs to each other and to USA300 strains used in earlier studies.
The genomes of eight of the 10 patient samples were virtually identical, indicating they came from a common strain. The remaining two bacteria were related to the other eight, but more distantly.
The study appears in the Proceedings of the National Academy of Sciences.
