It’s early days yet, but the CDC says the flu season is so far humming along in unspectacular fashion, with plenty of vaccine available that matches up against the strains of the virus in circulation.
(Last year, of course, the H1N1 pandemic strain emerged too late to include it in the usual ... Read More
Bacterial infections may trigger as many asthma attacks in children as viruses do, new research suggests.
Viral respiratory infections, including colds and flu-like illnesses, have long been known to cause kids and adults with asthma to have an attack -- characterized by a fit of coughing, wh... Read More
It has long been hard for people to accept that they can be hurt, or even killed, by something they cannot see. But this is exactly what viruses do and have always done; they evade our body’s immune system, hijack our cells to create more viruses, and have consequently caused epidemics throughou... Read More

A virus best known for the damage it does to the liver can also damage brain cells, University of Alberta researchers report in a new study.
The research into the impact of hepatitis C on the brain is significant, they say, because it marks the first time scientists have been able to show tha... Read More
A drug-resistant bacteria has claimed 18 lives in Brazil's capital region this year, local media reported Saturday.
The bacteria – Klebsiella pneumoniae Carbapenemase (KPC) – is resistant to most of the common antibiotics on the Brazilian market, the report said.
Infections in the capital ... Read More
Researchers at Yale University have artificially created the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall.
The finding represents the first time scientists have engineered the cell wall of a pa... Read More
Are better treatments for Lyme disease on the horizon? Things are looking up, scientists say, thanks to new research into the genetic make-up of the bacteria that cause the tick-borne illness.
The research yielded complete genetic blueprints of the 13 different strains of bacteria that cause ... Read More
Scientists from the MARUM Center for Marine Environmental Sciences and the Max Planck Institute for Marine Microbiology in Bremen on board the German research vessel Meteor have discovered a new hydrothermal vent 500 kilometers south-west of the Azores. The vent with chimneys as high as one mete... Read More
Although vaccination against influenza can protect people from illness and help prevent the spread of flu, many Americans say they and their children won't be getting a shot this coming season, new surveys reveal.

A billion people living in underdeveloped areas around the world are infected with parasitic helminthes, worms that survive by residing in and feeding on their hosts. These infestations can cause chronic intestinal (and occasionally systemic) illnesses leading to long-term disability. Irah King ... Read More
The latest tests conducted by anthropologists at the Johannes Gutenberg University Mainz (JGU) have proven that the bacteria Yersinia pestis was indeed the causative agent behind the "Black Death" that raged across Europe in the Middle Ages.
The cause of the epidemic has always remained highl... Read More
“By next spring a live-virus vaccine against poliomyelitis will be in limited but regular use in the U.S. Licenses will be granted to manufacturers, as each qualifies, for commercial production of the vaccine developed by Albert B. Sabin of the University of Cincinnati. The licensing of the Sabi... Read More
Microbes matter, perhaps more than anyone realizes in biological development, and scientists now believe they could be a target for reducing cancer risks.
In a study of very basic biology of zebrafish, scientists focused on the developing intestine during its early formation in the sterile en... Read More
News that a hard-to-treat, potentially lethal germ had landed on US shores from India spawned sensational headlines last month about the emergence of a “superbug’’ capable of outwitting the best antibiotics available. So far, just three cases of this NDM-1 bacterium have been identified in the U... Read More
Doctors have long known that viral infections can bring about asthma attacks and the shortness of breath, coughing, and wheezing associated with them. But while viral infections cannot be treated, scientists at the Danish Paediatric Asthma Centre at the University of Copenhagen and Copenhagen Un... Read More
Geert van der Kraan, Department of Biotechnology, Delft University of technology, believes the ups and downs of the bacteria in an oil field provide a useful source of information for keeping tabs on the state of the oil field itself. In theory, this process known as 'biomonitoring' can increase... Read More

MOSQUITOES infected with bacteria that stop them transmitting the dengue virus will be released into the wild next year.
Some 100 million people in the tropics get dengue fever each year, and 40,000 are killed by it. The virus's range is expanding, and last week France reported its first loca... Read More
