    Am I understanding this correctly...some Streptococci are "resistant" to certain drugs only because other bacteria are?

  • But sometime around the 31,500th generation, something dramatic happened in just one of the populations - the bacteria suddenly acquired the ability to metabolise citrate, a second nutrient in their culture medium that E. coli normally cannot use.

    "According to the World Health Organization, 2.5 billion people around the globe are without access to sanitary toilets, which results in the spread of deadly diseases. Every year, 1.5 million people-mostly those under the age of five-die from diarrhea."

    This is the infrastructure side of many of the microbes (and more importantly the diseases associated with them) we learned about.

  • vaccinemakers have introduced newer, "acellular" vaccines that consist of refined pertussis proteins that provide immunity against disease without severe side effects.
  • Children who had received only the acellular vaccine were more than 5.6 times more likely to get sick than those who received the old, whole-cell vaccine, the team will report next month in Pediatrics. Those receiving one or more of each type had an intermediate risk.

    They describe attachment of phages to the surfaces of materials like those used in implanted medical devices, and evidence that the phages remain active, killing E. coli and Staphylococcus aureus. Those bacteria cause the most common hospital-acquired infections.

    This is the last thing we need! Another strain of bird-to-human transmitted virus, and researcher believe this could be the worst one yet. While research on this virus is still being conducted in China, there is already strong evidence that this could be the next big flu outbreak.

    Not exactly a scientific article, however the sources are from science journals. This demonstrates how simple things that may be routine (like going to the gym) or that we don't give much thought about (going out for a few drinks with friends) can increase our risk for flu infection.

One-two punch could be key in treating blindness - 0 views

  • Researchers have discovered that using two kinds of therapy in tandem may be a knockout combo against inherited disorders that cause blindnes
  • In 2010, they restored day vision in dogs suffering from achromatopsia, an inherited form of total color blindness, by replacing the mutant gene associated with the condition.
  • While that treatment was effective for most younger dogs, it didn't work for canines older than 1 year
  • ...7 more annotations...
  • "Gene therapy only works if the nonfunctional cell that is primarily affected by the disease is not too degenerated,"
  • To test their theory, they again performed gene therapy but first gave some of the dogs a dose of a protein called CNTF
  • At a high enough dose, its effect on photoreceptors is a bit like pruning flowers: It partially destroys them, but allows for new growth.
  • But it worked.
  • "All seven dogs that got the combination treatment responded, regardless of age.
  • Those disorders affect individuals of both species in much the same way, so the combination treatment's promise isn't just for Fido.
  • One treatment option alone might not be enough to reverse vision loss, but a combination therapy can maximize therapeutic success."

    This is so amazing. Definitely interesting that they used dogs which are more complex than rats or mice so if they could use these on people it would definitely change the way the world saw animal testing/research....pun intended haha! pretty cool quick read
