The measles vaccine was introduced in the US 50 years ago, and now a panel from the Centers for Disease Control and Prevention has said the elimination of measles, rubella and congenital rubella syndrome has endured through 2011. However, the organization warns that measles still poses a threat, citing a 2013 spike in cases.

Researchers have created a new test that uses sugar and gold nanoparticles to detect the influenza virus within 30 minutes, and it can even distinguish between human and avian strains. This is according to a study published in the journal Organic & Biomolecular Chemistry.The research team, led by Prof. Robert Field of the John Innes Centre and Prof.

Infants and toddlers frequently carry toxigenic Clostridium difficile, usually with no harm to themselves, but can serve as a reservoir and spread the bacteria to adults in whom it can cause severe disease, according to a study by a team of Swedish researchers published ahead of print in the Journal of Clinical Microbiology.

Sepsis, or septicaemia, is a devastating disease that is difficult to diagnose early and for which treatment options are limited. The number of deaths from sepsis exceeds those from lung cancer, and from breast and bowel cancer combined.
A natural antibiotic turns out to be a lethal weapon in the fight against tuberculosis. Scientists have discovered it has an unexpected dual action that dramatically reduces the probability that TB bacteria will become resistantTechnology has made it possible to synthesize increasingly targeted drugs. But scientists still have much to learn from Mother Nature.

Culling vampire bat colonies to stem the transmission of rabies in Latin America does little to slow the spread of the virus and could even have the reverse effect, according to University of Michigan researchers and their colleagues.Vampire bats transmit rabies virus throughout Latin America, causing thousands of livestock deaths each year, as well as occasional human fatalities.
In the arms race between bacteria and modern medicine, bacteria have gained an edge. In recent decades, bacterial resistance to antibiotics has developed faster than the production of new antibiotics, making bacterial infections increasingly difficult to treat.
A team of Danish investigators has shown how to identify pathogens faster, directly from clinical samples. The research, published online ahead of print in the Journal of Clinical Microbiology appears in the journal's January 2014 issue.The investigators used a technique known as whole genome sequencing to identify and completely characterize bacteria causing urinary tract infections.

Understanding how bacteria adapt so quickly to changes in their external environment with continued high growth rates is one of the major research challenges in molecular microbiology. This is important not least for our understanding of resistance to antibiotics.
Researchers have identified a protein that causes loss of function in immune cells combatting HIV. The scientists report in a paper appearing online in the Journal of Clinical Investigation that the protein, Sprouty-2, is a promising target for future HIV drug development, since disabling it could help restore the cells' ability to combat the virus that causes AIDS.

In a study of adults with severe bacterial meningitis, therapeutic hypothermia (reduction of body temperature) did not improve outcomes, and it may even have been harmful, according to a study appearing in JAMA. Among adults with bacterial meningitis, the case fatality rate and frequency of neurologic complications are high, especially among patients with pneumococcal meningitis.

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series features an advance in smartphone-based imaging that could help physicians in resource-limited locations monitor their patients' health. The development converts smartphones into powerful mini-microscopes that, for the first time, can detect individual viruses.

Tracking a nation's health can be a painstaking business. But now, a team of researchers from the University of Pittsburgh have brought together and digitized all the weekly surveillance reports of diseases in the US since 1888 into one database.The researchers collated all weekly notifiable disease surveillance tables published between 1888 and 2013 - approximately 6,500 tables.

Scientists have created a device that is able to detect a person's risk of infection from a drop of blood within minutes, as opposed to current methods, which can take up to 2 hours. This is according to a study published in the journal Technology.

Sepsis, the body's response to severe infections, kills more people than breast cancer, prostate cancer and HIV/AIDS combined. On average, 30 percent of those diagnosed with sepsis die.A new study conducted by Jamey Marth, director of UC Santa Barbara's Center for Nanomedicine and professor of the Sanford-Burnham Medical Research Institute, reports a new method to increase survival in sepsis.

A new report from children's charity UNICEF has revealed that more than 850,000 infants have been saved from contracting HIV since 2005 in low- and middle-income countries, and that new adolescent infections could be halved by 2020 with more focus on interventions.

New research from Lund University in Sweden suggests that a new aggressive strain of HIV develops more rapidly into AIDS than other current strains.From first infection with HIV to developing AIDS can be as short as 5 years - the shortest known for HIV-1 types - say the researchers.The new strain is a "recombinant" virus - a cross of two viruses that meet in an infected person.

Garlic may be bad for your breath, but it's good for your baby, according to a new study from the University of British Columbia.
Scientists at the Institute for Genome Sciences at the University of Maryland School of Medicine and physicians at Sinai Hospital, Baltimore, MD, have found that restoring the normal, helpful bacteria of the gut and intestines may treat patients suffering from recurrent Clostridium difficile infections. Transplanting fecal matter of healthy donors into patients with recurrent C.
A new study is helping to provide a better understanding of vaccines for whooping cough, the common name for the disease pertussis. Based on an animal model, the study conducted by the U.S.
