Investigators at the Harvard School of Engineering and Applied Sciences (SEAS) say that the structure of the extracellular matrix enveloping bacteria capable of producing biofilms is set up in such a way that it literally forces the microorganisms to swell, spread and expand their colonies.
Biofilms are layers of p... |

Following any type of implant procedure, patients' immune systems are down, making their bodies prime for infection. Some heart implant patients develop a potentially-lethal type of blood infection, and researchers have just recently been able to pinpoint why and how this happens.
Apparently, a certain type of... |

Certain types of bacteria were found to be able to produce biofilms that are significantly more efficient at repelling water than Teflon is. This is the same material used to make non-sticky pans. According to a new study, it would appear that these biofilms, belonging to only a few species of microorganisms, are the... |

A new method to fight bacterial infections associated with contact lenses, that can also be used in bacterial infections related to severe burns or cystic fibrosis, has been developed and successfully tested by researchers at National Jewish Health and the University of Texas Southwestern Medical Center. The eye has... |

In a finding that could lead to the development of new therapies against bacterial infections, experts recently found out that certain bacteria can basically get up and “walk” when creating biofilms.These are structures that cover bacterial colonies after the microorganisms start taking hold of a new host... |

In one of the most interesting conclusions ever to be derived from a scientific study, researchers learned recently that bacteria, microorganisms that exist virtually anywhere on the planet, have a sense of smell.This is a very interesting discovery, considering that fact that some of the worst smells you can name mo... |

When the NASA orbiter Atlantis takes off on May 14, for its final planned flight, it will also carry a scientific experiment devised by researchers at the Rensselaer Polytechnic Institute (RPI). Experts here have developed a special container, in which they will place a large group of microorganisms, mostly bacteria.... |

Over recent years, scientists have made numerous, new discoveries in the field of microbiology and bacterial research, and one of the most important finds has been the fact that the microorganisms that cause chronic lung infections “speak” with each other. This communication is devastating for the human b... |

Most often, when bacteria create nasty infections inside human hosts, they defend themselves against antibiotics and the immune system via a coat of slimy proteins, known as a biofilm. These biofilms are notoriously hard to destroy, and, if they occur on implanted prosthetic devices, they are most often destroyed by ... |

One of the main dangers plaguing all sorts of medical tools, devices and human implants at this point comes from a bacterium known as Staphylococcus epidermidis. Opportunistic by nature, the organism regularly lives on our skins, and is as harmless as it comes. However, when it hitches rides inside us via needles... |

When thinking of plasma, the first thing that comes to mind is temperature. A whole lot of it, in fact. Millions of degrees are required to turn gas into this state, and experts at the University of Southern California now want to use it on our teeth. They recently created a new plasma tool, which uses the matter to ... |

Given the increasing incidence of MRSA infections in US hospitals, over the past years scientists have been trying to create chemicals that would finally eradicate the resilient Methicillin-resistant Staphylococcus aureus (MRSA) bacteria, as well as other related microorganisms. They wreak havoc in hospitals, as they... |
