New insights in survival strategies of bacteria

Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial ...

Epidemic outbreaks caused by environment, not evolution

Researchers have traced genetic changes in a bacterial pathogen over 450 years, and claim that epidemics of bacterial disease in human history may be caused by chance environmental changes rather than genetic mutations.

A bacterial ballistic system

Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have determined the structure of a crucial part of one of these ...

Antimicrobial edible films inhibit pathogens in meat

Antimicrobial agents incorporated into edible films applied to foods to seal in flavor, freshness and color can improve the microbiological safety of meats, according to researchers in Penn State's College of Agricultural ...

Nasty nanoinjectors pose a new target for antibiotic research

If you've ever suffered the misery of food poisoning from a bacterium like Shigella or Salmonella, then your cells have been on the receiving end of "nanoinjectors"—microscopic spikes made from proteins through which pathogens ...

Researchers find genetic cause for citrus canker

Researchers from the Institute of Food and Agricultural Sciences at the University of Florida are closer to finding a possible cure for citrus canker after identifying a gene that makes citrus trees susceptible to the bacterial ...

Probe opens new path for drug development against leading STD

Biochemical sleuthing by an Indiana University graduate student has ended a nearly 50-year-old search to find a megamolecule in bacterial cell walls commonly used as a target for antibiotics, but whose presence had never ...
