Evidence suggests that antibiotic use in agriculture has contributed to antibiotic resistance in the pathogenic bacteria of humans

Doctors have become increasingly concerned by the problem of "super-bugs" - bacteria that have become resistant to standard antibiotics.

HIF-1alpha expression regulates the bactericidal capacity of phagocytes

When microorganisms invade the body, immune mechanisms kick in to fight them off. The infected tissues typically show depleted oxygen levels, and a protein called HIF-1 alpha regulates this. Interestingly, the cells responsible for destroying the foreign pathogens are effective in this low-oxygen environment.

Scientists solve structure of a critical innate immune system protein

Scientists at The Scripps Research Institute have solved the structure of a crucial human immune system molecule called TLR3, an acronym for Toll-like receptor three. In an upcoming issue of the journal Science, the protein is described as a large horseshoe-shaped coil composed of 23 leucine-rich repeats (LRRs).

Technique called phylogenetic footprinting reveals new gene regulation system

By comparing 140 sequenced bacterial genomes, researchers have uncovered a system for regulating genes essential to bacterial replication - and they did it solely by computer keystrokes and mouse clicks.

Textiles with permanent antibacterial properties

Antimicrobial agents are not new to the marketplace. Our stores are filled with antibacterial soaps and gels, and in a post-9/11 world, wearable protection from biological agents is in increasing demand. So far, antimicrobial textile production has used coatings that can wash away over time, reducing the useful life of protective clothing.
