Using 'Bacteria-Eaters' to Prevent Infections On Medical Implant Materials - 0 views

  •  
    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.

Your Immune System 'Remembers' Microbes It's Never Fought Before, New Study Says - 0 views

  •  
    How do naive cells accomplish this microbial memory generation? It's all about the environment. People are constantly exposed to countless bacteria, fungi and viruses, everywhere all of the time. T cells might act like they're reacting to something they've seen before--maybe the bacteria's proteins look similar to that of a harmless bug, and the cell is fooled.

New Insights Into Ebola Infection Pave the Way for Much-Needed Therapies - 0 views

  •  
    Little research is available on how the Ebola virus buds from the plasma membrane of human cells, says senior study author Robert Stahelin of Indiana University School of Medicine. "By shedding light on this process, our study will help us to identify potential drug candidates that could interfere with this step in the viral life cycle.

Pseudomonas aeruginosa Turns Protein Into a Virulence Factor in One Easy Step - 0 views

  • To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells.
  • P. aeruginosa, one of the most common causes of hospital-acquired pneumonia.
  • P. aeruginosa mostly uses this protein called elongation factor-Tu (EF-Tu) inside the cel
  • ...10 more annotations...
  • but she and her collaborators have learned that as a virulence factor, it could represent a vulnerability for the bacterium
  • EF-Tu is presumed to be an essential protein, and it's performing these moonlighting functions as well. If we figured out how it was doing that, we could devise strategies to inhibit it," says Goldberg.
  • acquired pneumonia and is the leading cause of death among critically ill patients whose airways have been damaged by ventilation, trauma, or other infections.
  • P. aeruginosa takes
  • the protein EF-Tu, which was generally thought to exist only inside the cell, and decorates the exterior of the cell with it, but in a modified form.
  • EF-Tu is modified somehow to mimic ChoP, allowing P. aeruginosa to enjoy the benefits of ChoP.
  • , ChoP carries out a crucial step for setting up an infection for a number of different types of respiratory pathogens.
  • Using a host of techniques, including mass spectrometry, site directed mutagenesis of key residues in the protein, and genetic loss of function/gain of function studies, they found that P. aeruginosa only makes small changes to EF-Tu to get it to mimic this powerful ligand. P. aeruginosa transfers three methyl groups to a lysine on EF-Tu, giving it a structure similar to ChoP and allowing it to fit in the PAFR receptor in the way ChoP does.
  • "It allows [P. aeruginosa] to adhere to the cells and invade,"
  • "Its interaction with humans is accidental. It's an opportunist. The fact that it has this novel modification on this protein that is inherent in the bacterium that enables it to attach and persist and cause disease is exciting,"

    Interesting!! however, very scary. It just keeps modifying itself and being more virulent. what's next?!

Genes show one big European family - 0 views

  • to a new study of the DNA of people from across the continent.
  • This was predicted in theory over a decade ago, and we now have concrete evidence from DNA data,
  • But even a pair of individuals who live as far apart as the United Kingdom and Turkey -- a distance of some 2,000 miles -- likely are related to all of one another's ancestors from a thousand years ago.
  • ...3 more annotations...
  • Ralph and Coop used ideas about the expected amount of genome shared between relatives of varying degrees of relatedness
  • Ralph and Coop looked for shorter blocks of DNA that were shared between cousins separated by many more generations
  • But in large samples, rare cases of distant sharing could be detected. With their analysis, Coop and Ralph were able to detect these shared blocks of DNA in individuals spread across Europe, and calculate how long ago they shared an ancestor.

Lucky Bacteria Strike It Rich During Formation of Treatment-Resistant Colonies: Researc... - 1 views

  •  
    Researchers are looking at how biofilms form in order to better understand how to battle their ability to be resistant to many antibiotics
  •  
    Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly resilient communities, known as biofilms. It turns out that a lucky few bacteria become the elite cells that start the colonies, and they organize in a rich-get-richer pattern similar to the distribution of wealth in the US economy, according to a new study..

Coccidioidomycosis-A Fungal Disease of the Americas - 0 views

  •  
    This paper is an overview of Coccidioidomycosis. The explains the demographics, the life cycle, history, immunology, and treatment. The hope for a vaccine is also prevalent in this paper.  The paper summarizes Coccidioidomycosis and gives quick details about it.  Excellent paper on learning about the disease without diving in too deeply.

  •  
    This paper does an excellent job researching the correlation of the methylation of the STAT-1 gene and genetic mutations in coccidiodiomycosis and histoplasmosis. The paper shows evidence of the methylation of the STAT-1 by the PIAS1 protein. This gene mutation immunologically challenges the IFN-γ and alters the body's defense mechanisms. Excellent paper on a very scary disease. Hopeful for a vaccine!!!

Pathogen turns protein into a virulence factor in one easy step - 0 views

  •  
    This is more of a blurb (rather than an article) about P. aeruginosa making three small changes to the EF-Tu protein in order to gain entry into human cells. Understanding these changes appears to be a great link to understanding/studying hospital-acquired pneumonia. Not sure how I feel about the comment comparing proteins to a spork in a takeout meal....

10 Ways You May Put Yourself at Risk for Flu (Without Realizing It!) - 0 views

    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.
