Researchers develop technologies to devour food pathogens

... by shining a laser though a petri dish containing bacterial colonies. A computer program determines the type of bacteria by analyzing how light is refracted-a unique "scatter pattern." Bhunia has shown his technology is capable of recognizing Listeria monocytogenes, a microbial pathogen that is the leading ...

Controlling antibiotics and antibiotic resistance in hospitals

The study found that if a hospital had implemented measures to control the duration of administration of an empiric antibiotic, the institution had lower antibiotic resistance r...

Researchers identify new weapon to fight deadly bacterial sepsis

... the most dangerous risks of contracting a serious bacterial infection is that the victim may develop sepsis--an overreaction by the immune system causing destructive inflammation throughout the body, often leading to heart and other organ failure and death. Even the best hospital intensive care units may be h...

Transmission of antibiotic-resistant bacteria linked to previous intensive care unit room occupants

...dated cleaning practices are effective in reducing bacterial spread. "Although high-risk rooms may exist because of difficult-to-clean design or poor placement of hand hygiene equipment, transmission may be more directly linked to a prior occupant who harbors a resistant organism rather than to a particular r...
