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

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

Pertussis on Rise in U.S. Elderly - ICAAC 2013

Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis. Since the early 1980s, there has been an overall trend of an increase in reported pertussis cases. In this video participants discuss the resu... Read More

A retrovirus makes chicken eggshells blue

When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More

The Role of Vitamin D Supplements in Preventing and Treating Disease - ICAAC 2013

There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More

The Role of the Microbiome in Infection Control - ICAAC 2013

The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

New technology transforms research in viral biology

Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body—to see, for example, what happens in lung cells when a deadly respiratory virus attacks them.

In the journal Cell Host & Microbe, investigators say such a tec... Read More

Biologists uncover mechanisms for cholera toxin's deadly effects

Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much as half of their body fluids in a single day.

Two groups of scientis... Read More

Shingles Vaccine Coverage Low in Elderly Americans - ICAAC 2013

Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More

Human Interferon Kills Resistant H7N9 Influenza - ICAAC 2013

During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More
