The bacterial genus Mycobacterium has the dubious honor of including species responsible for two of the best-known chronic human infectious diseases: tuberculosis and leprosy. But unlike their more famous cousins, for which effective treatment strategies have long been available, it is the 200 or so lesser known Mycobacterium species that are currently causing a resurgence in pulmonary diseases in recent times.
The current leading method to assess the presence of viruses and other biological markers of disease is effective but large and expensive. It is prohibitively difficult for use in many situations, especially due to certain economic and geographic factors.
The world's food supply will become safer as the food industry shifts to high-resolution, whole-genome sequencing - which examines the full DNA of a given organism all at once. This move to make sequencing ubiquitous will lead to the consistently reliable detection of salmonella.
Importance of Copy-Number Variants in the Development of Insecticide Resistance in Malaria Mosquitoes
Researchers from Liverpool School of Tropical Medicine (LSTM), working alongside colleagues from the Wellcome Sanger Institute, Cambridge and the Big Data Institute, University of Oxford, have used whole genome sequencing to understand copy-number variants (CNVs) in malaria mosquitoes and their role in insecticide resistance.
Infections caused by the bacterium Vibrio vulnificus – known as “flesh eating” bacteria – are becoming more common in northern waters, whose surface temperatures are rising due to climate change. A recent study showed that infections are increasing in areas further north such as the Delaware Bay.
Scientists at Duke University have identified one kind of lung cell that can hustle to repair its damaged DNA and survive an attack of the influenza A virus while other kinds of cells around it die in droves.
Among HIV researchers, one seemingly indestructible HIV-like strain has earned the nickname "death star." That's due to the strain's reputation for killing off hopes for potential vaccines and immunotherapies that could prevent the disease.
McMaster University researchers have developed a novel new gel made entirely from bacteria-killing viruses. The anti-bacterial gel, which can be targeted to attack specific forms of bacteria, holds promise for numerous beneficial applications in medicine and environmental protection.

A research team led by Tufts University engineers has developed a 3D printed pill that samples bacteria found in the gut -- known as the microbiome -- as it passes through the gastrointestinal tract (GI).
