Hospitals Fight To Stop Superbugs' Spread : NPR - 0 views

  • CONAN: Well, is there something that - some things that every hospital or every clinic should be doing in order to minimize the risk? PERENCEVICH: I think one of the most important things they can do is make sure their microbiology lab is able to detect these strains.

Medical laboratory and biomedical science: C. difficile outbreak at Ottawa hospital - 0 views

  •  
    The Ottawa Hospital has been severely criticized in a report about practices and hygiene. The report was commissioned following a high number of Clostridium difficile cases over a two year period. This is especially relevant to me because it encompasses both CLS and microbiology.

Ancient Fungus Discovered Deep Under Ocean Floor - Yahoo! News - 0 views

    This could have huge implications in the microbiology field. If they could somehow find an antibiotic use out of this fungus it could help fight bacteria that is resistant to most drugs on the market today.

New Technologies in Clinical Microbiology - 0 views

  • Unfortunately, when laboratory methods rely solely on cultivation of pathogens and traditional phenotypic methods of pathogen characterization, physicians are forced to deduce the presence of BSI based on clinical symptoms, which are often nonspecific. Subsequently, antibiotic therapy is initiated based on clinical and epidemiologic profiles (28) rather than on laboratory evidence. Typically, within 1 to 3 days a microscopic Gram stain category (Gram-positive bacteria, Gram-negative bacteria, or fungi) provides physicians with a general direction for antibiotic therapy. Definitive results that eliminate the need for broad-spectrum therapy and enable de-escalation and the tailoring of treatment to the most effective antibiotic regimen often require more than 3 to 5 days. This gap has been implicated as one reason for high mortality and the emergence of drug-resistant microbes.

      Alison, I found this reference after our chat today at the end of the lab. I think you would find this paper very interesting.
  •  
    This paper is an excellent review on the need for improved protocols for microbial identification the technologies that are under development.

BMC Microbiology | Full text | Cultivation conditions and the diffusion of oxygen into ... - 0 views

  •  
    Bacterial cultivation requires consideration of three things: The bacterial strain, cultivation medium, and cultivation conditions. Most microbiologists dutifully report their choice of strains and cultivation media in manuscripts; however, these same microbiologists often overlook reporting cultivation conditions. Without this information, it is difficult to determine if cultures were grown aerobically, microaerobically, or anaerobically.

H. Boyd Woodruff, Microbiologist Who Paved Way for Antibiotics, Dies at 99 - The New Yo... - 0 views

  • In high school, he considered becoming an architect but, he later recalled, decided he wanted to be a chemist after taking an experimental course that encouraged “unexpected smells and disruptions of nearby classes,” he wrote in the Annual Review of Microbiology in 1981.
  • During that suit, Dr. Waksman said that in isolating streptothricin, Dr. Woodruff had contributed “as much as 20 times” more than Dr. Schatz to the later discovery of streptomycin,
  • “The studies of Albert Schatz in his discovery of streptomycin,” he said, “were dependent on the initial antibiotic demonstration by Boyd Woodruff that one could isolate soil microorganisms, culture them and recover inhibitory compounds from them.”

For DTaP Vaccine, Thigh May Be Better Injection Site Than Arm - NYTimes.com - 0 views

  • researchers found that children between the ages of 1 and 3 who were given the DTaP vaccine in their thigh instead of in their upper arm were around half as likely to have a local reaction

Really? The Claim: Hand Sanitizer Stops Norovirus Spread - NYTimes.com - 0 views

Fecal Treatment Gains Favor for Some Illnesses - NYTimes.com - 3 views

  • A new study finds that such transplants cured 15 of 16 people who had recurring infections with Clostridium difficile bacteria, whereas antibiotics cured only 3 of 13 and 4 of 13 patients in two comparison groups.
  •  
    I didn't know this was even possible. I wonder how they convinced people to donate. "The donors were tested for an array of diseases to make sure they did not infect the patients." I wonder how extensive that panel was and what they tested for.
  •  
    Isn't this neat? I have met people who are hoping to get this treatment. Re: the screening, I think it is probably just for the absence of pathogens. As the article states, we really don't know what the "good" bacteria are that help these patients.
  •  
    RE: I would hope that they would check for things like HIV and other blood to blood transmitted diseases. If there was a bleed in the GI tract of both the donor and the patient, I could imagine it would be a problem.

    This is really sweet. Applying microbiology to home design and efficiency. This chandelier is run completely off bacteria. There is not an on/off switch but you can configure the light to different a brightness by changing the bacteria in the petri dishes or changing the dish size.

  • Infectious disease specialist Dr. Brad Spellberg, of the Los Angeles Biomedical Research Institute at the Harbor-UCLA Medical Center, likens the situation to the Titanic's ill-fated voyage. "We're not talking about an iceberg that's down the line," he says. "The ship has hit the iceberg. We're taking on water. We already have people dying. Not only of CRE, but of untreatable CRE."
  • "If CRE spreads out of hospitals and into communities, that's when the ship is totally underwater and we all drown," Spellberg says.
