PROVIDENCE, R.I. [Brown University] -- A new study of the relationship between violent conflict and HIV incidence in sub-Saharan Africa finds that HIV incidence may be at its worst in the period before hostilities break out. The Brown University analysis reports that the rate of new infections r... Read More
A type of bacteria plucked from the bottom of the ocean could be put to work neutralizing large amounts of industrial carbon dioxide in the Earth's atmosphere, a group of University of Florida researchers has found. Read More
Oxford University scientists have found that the more effective way to beat malaria is to use less effective drugs some of the time. Read More
Athens, Ga. - People feeding white ibises at public parks are turning the normally independent birds into beggars, and now researchers at the University of Georgia say it might also be helping spread disease. Read More
Scientists at the Institut Pasteur in Cambodia, the Institut Pasteur in Paris and the CNRS provided proof that people infected by dengue virus but showing no clinical symptoms can actually infect mosquitoes that bite them. It appears that these asymptomatic people - who, together with mildly sym... Read More
GENEVA and SEATTLE, 10 November 2015--Five years after the introduction of an affordable conjugate meningitis A vaccine, immunization has led to the control and near elimination of deadly meningitis A disease in the African "meningitis belt." In 2013, only four laboratory-confirmed cases of meni... Read More
Although there has been some movement toward more judicious use of antibiotics, there are still people who take the drugs thinking it will help the common cold, and dentists who regularly prescribe antibiotics for patients prior to some common oral surgeries like third molar extraction.
These... Read More
Extracellular vesicles are membrane-bound structures that are released away from cells into the environment. These vesicles carry signaling molecules, nutrient scavenging molecules, immune-modulating molecules – the list goes on and on. Every cell type examined produces vesicles, too: bacterial,...

Washington, DC – November 10, 2015 – A single course of antibiotics has enough strength to disrupt the normal makeup of microorganisms in the gut for as long as a year, potentially leading to antibiotic resistance, European researchers reported this week in mBio®, an online open-access journal o...

What if a single vaccine could protect people from infection by many different viruses? That concept is a step closer to reality. Read More
Researchers from the University of North Carolina at Chapel Hill have discovered a new bat SARS-like virus that can jump directly from its bat hosts to humans without mutation. However, researchers point out that if the SARS-like virus did jump, it is still unclear whether it could spread from h... Read More
Unknown organism, possible Bacillus spp, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was a light brown and mat. The center of the growth was smooth with rhizoid like growth on the edges which were mucoid... Read More
Unknown organism, possible yeast or Bacillus, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow and mucoid . There are numerous rings of growth (looks like layers of rope) with lobate margins.... Read More
Unknown organism, possible yeast, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was light yellow, mat in the center and mucoid towards the outside. There are several rings of growth with each ring havin... Read More
75% of the ~390 million people infected with dengue viruses present with no symptoms (asymptomatic). It is generally assumed that these asymptomatic infections cannot be transmitted to mosquitos. Not only does this study show that people with asymptomatic infections transmitted the virus to mo... Read More
