This sculpture made of purple and clear glass beads depicts bacteriophage Phi174, a virus that infects bacteria. It rests on a surface that portrays an adaptive landscape, a conceptual visualization. The ridges represent the gene combinations associated with the greatest fitness levels of the vi... Read More
On the issue of antibiotic-resistant bacteria and animals, the first thing that comes to mind is livestock and other farm-based animals that are regularly fed antibiotics as growth promoters, but they are not the only source of resistance. Participants discuss studies showing that non-farm anim... Read More
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
Extended spectrum beta-lactamases (ESBL's) are enzymes that enable bacteria to resist multiple antibiotics. In the past few years ESBL-producing enteric bacteria (such as E. coli) have become an increasingly common cause of community acquired infections worldwide. The source of these organisms i...

Dictyostelium discoideum is a soil-living amoeba. A group of 100,000 form a mound as big as a grain of sand.
The hereditary information is carried on six chromosomes with sizes ranging from 4 to 7 Mb resulting in a total of about 34 Mb of DNA, a multicopy 90 kb extrachromosomal element that h... Read More
Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... Read More
It’s become a sad fact that many people being treated in health-care facilities end up catching a bad -- and potentially deadly -- bug in the very place where they’re supposed to get better.
