  • When Miltefosine was first introduced as part of a regional campaign in the Indian subcontinent for kala-azar elimination a decade ago, the drug proved to be very effective
  • so far no Miltefosine-resistant parasites were detected in patients

  • i diagnosed with HIV at birth and immediately put on antiretroviral therapy.
  • brought back into care at 23 months, despite being off treatment for five months, the child was found to have an undetectable viral load
  • d today no signs of HIV infection in the child can be detected by the most sensitive means available.

  • physician was able to treat his leukemia with a stem-cell transplant from a person who was born with a genetic mutation causing immunity to HIV infection. Following the transplant, Mr. Brown was able to stop HIV treatment without experiencing a return of his HIV disease

  • Doctors in the US have made medical history by effectively curing a child born with HIV, the first time such a case has been documented.
  • Dr Hannah Gay, who cared for the child at the University of Mississippi medical centre, told the Guardian the case amounted to the first "functional cure" of an HIV-infected child.
  • but it is likely that a tiny amount remains in their body.

  • ypically, women with HIV are given antiretroviral drugs during pregnancy to minimise the amount of virus in their blood. Their newborns go on courses of drugs too, to reduce their risk of infection further. The strategy can stop around 98% of HIV transmission from mother to child.

      I had no idea modern medicine was this effective against transmission from mother to child.
  • "It is far too early for anyone to try stopping effective therapy just to see if the virus comes back," she said.

    Exciting when AIDS research takes a step forward. However, is it true that although they cannot detect the virus, it may lie dormant? How sensitive are those tests? There was a case of a man who had HIV and leukemia and so they treated him with a bone marrow transplant from someone who was resistant to HIV. The man was said to be cured but there were later debates on the validity.

Viruses Can Have Immune System, Study Finds | Biology | Sci-News.com - 1 views

shared by Richard Herron on 03 Mar 13 - No Cached
  • A new research led by Dr Kimberley Seed from the Tufts University School of Medicine provides the first evidence that bacteriophages – viruses that infect and replicate within bacteria – can acquire a wholly functional and adaptive immune system.
  • The study, published today in the journal Nature, finds that a viral predator of the cholera bacteria can steal the functional immune system of bacteria and use it against its bacterial host.
  • Developing phage therapy is particularly important because some bacteria, called superbugs, are resistant to most or all current antibiotics.
  • ...2 more annotations...
  • This study focused on a phage that attacks Vibrio cholerae, the bacterium responsible for cholera epidemics in humans.
  • Finding a CRISPR/Cas system in a phage shows that there is gene flow between the phage and bacteria even for something as large and complex as the genes for an adaptive immune system,”

    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.

  • identified a weakness in at least one superbug that scientists may be able to medically exploit
  • discovered that two proteins already present in E. coli cells -- RbfA and KsgA -- need to be in balance with each other in order for ribosomes to function
  • RbfA does not exist in humans

    This has little to do with microbiology but this staining technique is much more badass than Gram staining.
