  • E. coli serotype O157:H7 is a Gram-negative, rod-shaped bacterium. The "O" in the name refers to the cell wall (somatic) antigen number, whereas the "H" refers to the flagella antigen.

    With antibiotic resistance looming, the failure of drug companies to develop new drugs to fight gram-negative bacteria could potentially lead to millions of deaths just from a common cold or from the flu. Drug companies cannot turn out new antimicrobials fast enough, and the ones that they do get out to the public cost billions of dollars.

    Scary to think that we're all at risk!

  • Apparently, all of this has been caused by contamination of drugs by a black mold called Exserohilum rostratum, which is common in the environment but almost unheard of as a cause of human disease.
  • For instance, on 13 occasions, they said, New England Compounding shipped out vials of drugs in three suspect lots before getting back results of their own tests confirming the drugs were sterile.

  • he may harbor a fungal infection that could kill him, there's no proof that he does — and there may never be.
  • many anxious patients are undergoing painful spinal taps and some are getting antifungal drugs that can damage the kidneys and liver.
  • The caution is warranted. This type of fungal infection can smolder for weeks and months before exploding into meningitis or causing massive strokes.
  • "It causes a quandary for the infectious disease doc to figure out, well, should this patient receive treatment at all?" O'Connell says. "Should they receive full-boat treatment, which would be an IV? Could they instead just be watched very closely with daily phone calls and visits to the office? We just don't know."
  • "Should we do lumbar punctures on those kinds of people so that we can anticipate those that are going to get symptomatic later and beat the fungus to it?" Schaffner wonders. "That is, initiate treatment much earlier, thus averting tissue damage, particularly those devastating strokes."
  • When to stop is also uncertain.
  • six months, maybe longer.

microbiology norovirus

shared by Casey Finnerty on 11 Feb 14 - No Cached
  • Over the past five years, an average of about 14 cruise ships a year have had outbreaks of diarrheal illness, and the culprit is almost always norovirus
  • The best way to avoid it is prevention, and the best prevention is hand washing.
  • The problem, he said, is passengers. “If Grandma is sick when she gets on, she’s going on the cruise anyway,” Dr. Vinjé said. “And that’s how the virus gets onboard. Then it lands on handrails and doorknobs, and the transmission continues.”
  • ...1 more annotation...
  • regardless of the origin, once onboard, the illness spreads widely. He says the reason is failure to clean restrooms properly.
