Stripping some mouth bacteria of their access key to gangs of other pathogenic oral bacteria could help prevent gum disease and tooth loss. The study suggests that this bacterial access key could be a drug target for people who are at high risk of developing gum disease.

A new study by food safety researchers at Drexel University demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry. The proof-of-concept study was published in the January issue of the Journal of Food Protection.

Salmonella remains a serious cause of food poisoning, in part due to its ability to thrive and quickly adapt to the different environments in which it can grow. New research has taken a detailed look at what Salmonella does when it enters a new environment, which could provide clues to ...

A new study demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry.

Could some cases of asthma actually be caused by an allergic reaction to a common environmental bacteria? New research findings suggests that this idea may not be as far-fetched as it seems.

The use of probiotic bacteria, isolated from naturally occurring bacterial communities, is gaining in popularity in the aquaculture industry as the preferred, environmentally friendly management alternative to the use of antibiotics and other antimicrobials for disease prevention. Known to the public for their use in yogurt and other foods to ...

Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail. The study, which investigates how bacteria change their disguise to evade the vaccines, has implications for how future vaccines can be made more effective.

Battles between bacteria and virus help reveal how new traits appear

Researchers have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts. These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in ...

Tumor-targeted bioluminescent bacteria have been shown for the first time to provide accurate 3-D images of tumors in mice, further advancing the potential for targeted cancer drug delivery.

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galápagos islands are more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report in a new study.Feces collected at several different sites from ...

Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galapagos islands were more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report. Many of the reptiles harbor E. coli bacteria that are ...
