Good bacteria, called probiotics, live within our intestinal tract. They are also known as comensual cells which outnumber human cells, 10 to 1. In other words, we are made up of more good bacteria than human cells which shows how important they are to health.

San Diego-based Optimer Pharmaceuticals has nailed the second big trial designed to prove it has a new antibiotic for a deadly infection people can get in hospitals.
Optimer said today that it reached its main goal of showing its experimental antibiotic, fidaxomicin, was roughly equivalent to... Read More
A new poll found the majority of parents have gotten or intend to get their children vaccinated against swine flu, but the majority of adults have not gotten or do not want swine flu vaccine for themselves.
The poll by Harvard School of Public Health shows 44 percent believe the H1N1 flu pand... Read More
Fewer people are getting sick with the swine flu than is typical for influenza rates this time of year - but public health officials still aren't ready to say the pandemic is over.
For the third week in a row, national rates of flulike illness are below the seasonal average, the U.S. Centers ... Read More
For millions of Americans, Super Bowl Sunday is all about going to somebody else's house for eating and drinking before, during, and probably after the game between the New Orleans Saints and Indianapolis Colts. Millions of tons of that food will be prepared by amateurs.
For their stake, you... Read More
China's reckless use of antibiotics in its health system and agricultural production is fuelling an explosion of drug-resistant superbugs that threaten global health.
Scientists have warned that Chinese doctors routinely prescribe multiple doses of antibiotics for sore throats, while farmers'... Read More
In this show, I report on four exciting stories: how rotifers do without sex, making diesel fuel using bacteria, a plant virus that tricks insects into spreading it, and how bacteria boost the immune system.
The biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It was thought that all creatures on Earth were divided into two main evolutionary categories, but ... Read More
In the age-old battle between man and microbe, people have tried in countless ways to keep their surroundings germ-free, ranging from plain old scrubbing, heat sterilization and chemical disinfectants to high-tech solutions like irradiation or drug-eluting coatings.
Now a new approach could m... Read More
The anticancer drugs, such as DNA replication inhibitors, stimulate bacterial adhesion and induce the bacterial SOS response. As a variety of bacterial mutants can be generated during SOS, novel phenotypes are likely to be selected under the drug pressure.Presentation of the hypothesisBacteria g... Read More
Monash University biochemists have found a critical piece in the evolutionary puzzle that explains how life on Earth evolved millions of centuries ago.
The team, from the School of Biomedical Sciences, has described the process by which bacteria developed into more complex cells and found thi... Read More

Unlike antibiotics, which kill many different types of bacteria, antiviral drugs for the most part need to target individual, specific viruses. A drug that attacks a multitude of viruses -- an antibiotic for viruses, effectively -- would be a significant boon for medicine. And a group of researc... Read More
Researchers at North Carolina State University have developed a "smart coating" that helps surgical implants bond more closely with bone and ward off infection.
When patients have hip, knee or dental replacement surgery, they run the risk of having their bodies reject the implant. But the sma... Read More
Researchers at the University of Copenhagen have become the first in the world to synthesize the entire protein that is responsible for life-threatening malaria in pregnant women and their unborn children. The protein known as VAR2CSA enables malaria parasites to accumulate in the placenta and c... Read More
Australian researchers are scrambling to develop drugs to fight off Acinetobacter baumanii, a new "superbug" that is causing fatalities overseas.
Experts say Acinetobacter is far worse than superbugs such as MRSA, which are already in Australian hospitals.
Australian health authorities sa... Read More
Thomas Cavalier-Smith, Department of Zoology, University of Oxford, has published a paper in which he identifies some of the key elements to understanding eukaryogenesis.
"Here I paint an integrated picture of how the nucleus, sex, and the eukaryotic cell cycle originated and congealed into ... Read More
