A central pursuit of microbial ecology is to accurately model changes in microbial community composition in response to environmental factors. This goal requires a thorough understanding of the drivers of variability in microbial populations. However, most microbial ecology studies focus on the ... Read More
Several weeks ago we perfected a plaque assay for Zika virus, based on our existing assays for enteroviruses. Shown is a photograph of two plates stained with crystal virolet with clearly delineated plaques. The cells are Vero and the Zika virus strain is MR766, an African isolate. Anyone intere... Read More
Rhesus monkeys were completely protected from Ebola virus when treated three days after infection with a compound that blocks the virus's ability to replicate. These encouraging preclinical results suggest the compound, known as GS-5734, should be further developed as a potential treatment, acco... Read More
Scientists know very little about the kinds of bacteria that we interact with on a daily basis in our homes. Researchers from Colorado, and North Carolina are interested in what kinds of microbes are living in your shower head.
They are hoping to find out where Nontuberculous mycobacteria is... Read More
Scientists from The University of Texas at Austin, the Stanford University School of Medicine and two other institutions have discovered that bacteria have a system that can recognize and disrupt dangerous viruses using a newly identified mechanism involving ribonucleic acid (RNA). It is similar... Read More
Ad hoc, uncoordinated and late. That’s how the UK government’s response to West Africa’s Ebola outbreak has been described in a report published on Monday by the House of Commons Science and Technology Select Committee.
The report calls for changes to enable the UK to identify threats earlier... Read More
Microbiologists attending Microbe 2016, the annual meeting of the American Society for Microbiology, attempt to explain their science in 30 seconds.
This video was produced during the Lights! Camera! Science! professional development workshop with the help of the attendees.
The music Ask R... Read More
A benefit of the voluminous wealth of research produced is that it allows us to stand on the shoulders of giants – we can take advantage of established facts, tools, and datasets. This may mean using a mutant library to find genes in your organism that are important for the process you study; ac... Read More
Having confirmed the first cases of infection in Suriname then in French Guiana, the Institut Pasteur in French Guiana has sequenced the complete genome of the Zika virus, which is responsible for an unprecedented epidemic currently sweeping through the tropical regions of the Americas. Publishe... Read More
The opening ceremony for the Summer Olympics 2016 will be held this Friday, marking the onset of two weeks of competition between the world’s best athletes. The world has been focused on Brazil and its preparedness – not only for the infrastructure required for the games, but also for any potent... Read More
A three-dimensional 'map' of a critical protein that malaria parasites use to invade human red blood cells could lead to a vaccine countering the most widespread species of the parasite. Read More
If there is a problem built for a systems-based research approach, climate change – with its complex carbon and nitrogen cycles, numerous species involvement, and interaction of geographical zones – would be an excellent candidate. Concurrent with the launch of the systems-based microbial resear... Read More
Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More
Viruses have proven to be wily foes. Attempts to fend off viruses that cause the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola, or Zika continue to elude drugs.
Given these challenges, scientists are tackling the problem from a different angle. The want to boos... Read More
Serratia marcencens and Corynebacterium xerosis on TSA make for a great valentine for any microbiologist! Read More
New research findings published in the February 2016 issue of the Journal of Leukocyte Biology, suggest that a new therapeutic strategy for HIV may already be available by repurposing an existing prescription drug. The drug, an enzyme called adenosine deaminase, or ADA, ultimately may be able to... Read More
Washington, DC – August 5, 2016 – Current events linked to the Zika virus make aggressive public health actions and funding to combat this emerging infectious disease more crucial than ever. Newly reported Zika cases in Florida are the first examples of US infection spread by local mosquitos. ... Read More
Evidence-based medicine is the approach used by doctors to make rational clinical decisions based on rigorous, well-controlled studies. By minimizing hunches, gut feelings, and anecdotal evidence, physicians and patients can follow recommendations that are most likely to have a positive outcome.... Read More
Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect.' Researchers from the University of Glasgow have demonstrated the Meselson effect for t... Read More
The study researchers found that placing a small, detoxified amount of E. coli in the guts of mice led to an increase in levels of leptin - known as the "satiety hormone."
Within 7 days of the increase, the number of sweet taste receptors on the rodents' tongues reduced, diminishing their ap... Read More
