While bacteria have been evolving for 3.5 billion years, mammals have evolved with bacteria for only 2.5 million years. Thus, it's not that surprising that humans appear to be losing the war on antibiotic resistance.
The issue of multidrug-resistance and the lack of antibiotics in the developme... Read More
In this episode of Virus Watch, we explore the finding that Zika virus infects the testis of mice, causing damage to the organ, reduced sperm production, and less fertility. The important question: does the same happen in humans? Read More
Astrobiología y ambientes extremos: En el episodio de hoy tenemos al Dr. Salvador Mirete, Investigador del Centro de Astrobiología, del Instituto Nacional de Técnica Aeroespacial de Madrid, España. La astrobiología se discute dentro del contexto de los ambientes extremos encontrados en la Tie... Read More
Houston Methodist researchers have discovered a set of immune proteins that facilitate long-lasting immunity against malaria. In a study recently published in Immunity (online Oct. 25), researchers reported that elevated production of specific proteins regulating the immune system within 24 hour... Read More
Aravinda de Silva, PhD, professor of microbiology and immunology, and Stefan Metz, PhD, a post-doc in de Silva's lab, make up one of only two U.S. teams to be named to the European Union-funded worldwide initiative. Sponsored by the European Union's Horizon 2020 Programme, the consortium is inve... Read More
Federal scientists have launched another test in human volunteers of a Zika vaccine. This one uses a more traditional approach than an experiment that started in August.
Federal officials are eager to develop a vaccine as quickly as possible, which is why they are pursuing multiple approaches... Read More
Q. Are people who work with books and manuscripts from the 14th and 15th centuries at risk from disease-causing bacteria or viruses from that time?
A. Almost certainly not, because of how diseases spread and how long most microbes can survive on dry surfaces.

A sample of Proteus mirabilis was inoculated on to a blood agar plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a halo around the growth in the center of the plate. Read More
Walk through any woods, branches swaying overhead, and you're surrounded by billions of the world's most efficient systems for collecting energy. Inside every leaf, blade of grass, and algal cell, clusters of proteins and tiny pigments, called photosynthetic antenna complexes, capture sunshine.

Raw milk collected from dairy farms has to travel to processing facilities before it is transformed into the delicious dairy products we consume. Because the milk from many dairy cows is collected together, any contamination issue from a single animal can lead to spoilage or contamination. How r... Read More
ust five months after federal health officials asked hospitals and physicians to be on the lookout for an often-fatal, antibiotic-resistant fungus called Candida auris, 13 cases have been reported, the Centers for Disease Control and Prevention announced Friday. It is the first time that the fun... Read More
