Study Suggests How Oral Bacterium Might Cause Cardiovascular Disease

admin — Wed, 05 Dec 2007 00:34:50 +0000

The oral bacterium or bacteria naturally inhabiting in the mouth of an individual are usually harmless. However, for some uncertain reasons, they become injurious and disease-causing once they have entered or infiltrated a different habitat. Researchers have been searching for some clues on how to resolve these problems. The more interesting thing is that how these bacteria came to infiltrate and damage the heart once they have attacked it. At the core of the debate on whether particular oral pathogens may possibly be a factor to the inception of cardiovascular illness is the subject of mechanism or procedure on how precisely bacteria take possession of the heart. Additionally, the steps or actions performed by the bacteria in the course of their colonization that initiate an immune reaction that leads to the inflammation frequently connected with cardiovascular disease. In one of the issues of the journal Cellular Microbiology the probable answers were published. (more…)

Staph Bacteria are Prolific Gene Swappers, Researchers Show

Whenever disease-causing bacteria encounter a new obstacle, they have a way to overcome it by exchanging DNA with their relatives in order to adapt to a new environments and conditions. This revelations by scientists from NIAID seem to settle the long-standing question of the origin, the how and why of two diseases. Toxic Shock Syndrome (TSS) and anti-biotic-resistant infections.

A unique group of nearly 40 new bacteria, which can be found almost everywhere, even in the absence of air, when given the right kind of food, has the capability to produce oxygen.
We can think of very many possible applications in this aspect. They could supply air tanks for deep-sea activities, or treat deep-wound injuries, or even dispose of toxic waste. (more…)

Science has come a long way in discovering the evolution of man and everything else. Only one thing remains constant, in all those billions and billions of years of development, one organism has an ingrained ability to survive, no matter what. This organism is known as bacteria. (more…)

Complex Cells Likely Arose From Combination of Bacterial And Extreme-Microbe Genomes

admin — Sun, 29 Jul 2007 06:16:43 +0000

In this article, Jim Lake and Maria Rivera, researchers from the University of California in Los Angeles (UCLA), released their report that complex cells found in the human body have probably been the result of a combination of genomes from a prehistoric microbe called Archaea in an effort to survive hostile environments.

Study Reveals How Bacteria Communicate About Their Environment

This is about a research study that exposes how bacteria communicate regarding their natural habitat.

In the article, the research project that commenced through raising obscure queries regarding the glowing marine bacterium has started to elucidate the workings of numerous bacteria and could end up in a novel class of antibiotics. Quorum-sensing gene may possibly result to new types of antibiotics. The article cited a professor of molecular biology in the person of Bonnie Bassler who discovered a gene that the bacteria utilize to perceive whether they are part of a thick or thin community of bacteria such that the bacteria may be living in the human as compared to when they are living in a puddle of water. Moreover, the researcher has found that more harmful and more common bacteria have the same gene. (more…)

PDT kills drug-resistant bacteria in lab

Research from the School of Dental Medicine has shown Photodynamic therapy PDT possibly will be an efficient cure for fungal infections and definite bacterial infections of the oral cavity, as well as some that are resistant to antibiotics. Researchers found that the bacteria S. mutans, as well as fungal organisms of the genus Candida, cultured from HIV patients, were very vulnerable to killing with minimal amount of PDT, both in laboratory dishes and on biofilms grown on denture material.

Molecular technique shows promise in destroying drug resistance in bacteria

admin — Wed, 13 Jun 2007 04:27:03 +0000

Medicinal opposing bacterium and bacteria are now everywhere in both hospital location and the larger community a paper that shows online ahead of publication in the Journal of the American Chemical Society. Urge, new strategies and targets are needed to fight drug resistant bacterium and bacteria. Drug opposing makes it hard to fight illness and raise the possibility of gaining one while in a hospital. According to the some research, in turn, has led to added fatality from infection, longer hospital stay and a larger use of more toxic and expensive drugs. (more…)

Pacifying bacteria prevents lethal post-op infections

By means of instilling a defensive covering into the intestines to calm down bacterium and bacteria there as a substitute of depending on antibiotics to eliminate them, the scientists were clever to protect mice from otherwise lethal infections. Pseudomonas aeruginosa is familiar, found in the intestines of about 3 percent of vigorous people. It is also a frequent cause of hospital acquired infections, particularly after major surgery. In the bowel, this germ can be harmless, or it can turn deadly, causing burn up resulting sepsis. This is an illness of human advancement, make clear. When people are harshly in poor health will put them in serious concern, where just about every thing to do alarms this bacterial traveler. (more…)

Bacteria vials, reported missing from College center, thought to be destroyed

admin — Wed, 13 Jun 2007 03:19:16 +0000

Here is an article about bacteria vials that were reported missing from a college center. Researchers in the Medical College of Wisconsins Center for Biopreparedness and Infectious Diseases reported on March 16, 2007, that they could not account for six vials of froen infectious bacterium cells. These vials were kept in a secured biosafety laboratory. These missing vials wre reported to contain a weakened strain of Francisella tularentis bacterium. The said bacterial strain is known to be the causative factor of the disease called Tularemia. (more…)
