In the study, samples of chicken skin were contaminated with both C. jejuni and bacteriophage, viruses that specifically infect and kill bacteria but are harmless to humans, while a control group received only the bacterium. The samples were stored at fresh and freezing temperatures for ten days. Daily testing results showed significantly less contamination in the bacteriophage samples, especially those kept at temperatures below freezing.
"The fact that phage are able to survive on the surface of chicken skin for a period of at least 10 days when stored under either fresh or frozen conditions is important when considering the potential efficacy and environmental impact of phage therapy on animals that carry campylobacter," say the researchers. "Phage of campylobacter along with their hosts can potentially survive on the retail product until well after its shelf life."

GUM DISEASE CONTRIBUTES TO HEART DISEASE
Periodontitis may be a contributing factor in the development of heart disease say researchers from Boston University and Harvard Medical School. Their findings appear in the October 2003 issue of the journal Infection and Immunity.
In the study, rabbits were fed a high-fat diet, one of the main factors contributing to the buildup of cholesterol deposits in
