Biologists Discover New Method for Discovering Antibiotics

Biologists at the University of California, San Diego have developed a revolutionary new method for identifying and characterizing antibiotics, an advance that could lead to the discovery of new antibiotics to treat antibiotic resistant bacteria.

The researchers, who published their findings ... Read More

3 germs are urgent threats to USA's health, CDC says

The overuse of antibiotics has caused three kinds of bacteria, including one that causes life-threatening diarrhea, one that causes bloodstream infections and one that transmits sexually, to become urgent threats to human health in the United States, federal health officials say in a landmark re...

Drug-Resistant Superbugs Kill At Least 23,000 People in the U.S. Each Year

Each year, more than two million people in the United States develop antibiotic-resistant infections, and at least 23,000 of them die as a result, says the first-ever national snapshot of the issue. That toll only rises when other conditions exacerbated by these infections are included in the co... Read More

UCLA researchers' smartphone 'microscope' can detect a single virus, nanoparticles

Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.

Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and h... Read More

It’s Time for Salmonella

If one were to ask, “What happens when Salmonella infects the gut?” it might not be obvious that you’d also need to ask, “What time is it?” But indeed you’d need to know the latter to appropriately address the former. An invading Salmonella, intent on setting up camp, is trying to pitch its tent... Read More

Vaccine seems to clear AIDS-causing virus from monkeys, scientists say

A promising HIV vaccine developed by researchers at Oregon Health & Science University eradicated the virus that causes AIDS in monkeys, and scientists hope something similar can soon be tested on humans.

AIDS in non-human primates is caused by simian immunodeficiency virus, or SIV, which is ... Read More

Soil microbiology guides fertiliser use

In an effort to help improve fertiliser application and timing in agricultural farming, researchers have set out to discover what environmental factors affect the microorganisms in soil and what influence these microorganisms have on nitrification rates.

CSIRO’s Cathryn O’Sullivan says the re... Read More

Siemens recalls microbiology testing panels: FDA

Germany's Siemens recalled 78,020 microbiology testing panels in the United States as they are reporting false results, U.S. health regulators said.

The defect found in certain MicroScan panels may lead to treatment of patients with inappropriate antibiotics or to a delay in the therapy they ... Read More

Shingles Vaccine Coverage Remains Low

Vaccination for shingles was around 16% in 2011 among those at the greatest risk for the disease, researchers reported here.

Although rates of vaccination against the herpes zoster virus among patients 60 and older grew more than 2.5-fold from 2008 to 2011 (OR 2.62, 95% CI 2.25-3.04), the pro... Read More

Older Adults at Risk for Whooping Cough

Whooping cough among adults 50 or older is much more common than generally thought, and the incidence appears to be rising, a researcher said here.

A mathematical model based on medical practice and laboratory databases suggested that pertussis among adults ages 50 through 64 more than double... Read More

Some Uses of Bacteria

Bacteria are very in these days—in probiotic drinks, in news articles, and in scientific research about the connections between healthy microbes and healthy bodies. A growing chorus of post-pasteurian voices are advocating for a new relationship with microbes, one where bacteria are respected an... Read More

Model Organism gone wild

Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More

Previously discovered hepatitis-associated Parvovirus-Circovirus Hybrid Presumed Laboratory Contaminant

Metagenomics has been responsible for the discovery of various novel and clinically relevant human and environmental microorganisms. However, great care must be taken with the conclusions each group makes concerning whether a novel microorganism is associated with any given disease or phenotype... Read More

How MALDI-ToF is Changing Clinical Microbiology - ICAAC 2013

Lasers are the new DNA. It is called matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) and it uses mass spectrometry to quickly test for hundreds of different pathogens in a small sample using a single automated device. MALDI-TOF is increasingly being used in clinical micr... Read More

High Dose Therapy for Influenza Drug - ICAAC 2013

Critically ill patients with the pandemic H1N1 influenza who received triple the standard dose of the influenza drug oseltamivir were 7 times more likely to completely clear the virus from their system in 5 days than those who received the standard dose. This discussion addresses the healthcare... Read More
