As the Pennsylvania Department of Health investigates human cases of infection with an uncommon type of Salmonella, possibly connected to dry dog food, state Health Secretary Dr. Calvin B. Johnson today reminded consumers of steps they should take to prevent illness when handling pet food and pet treats.

Pigs could be the key to understanding how antibiotic resistant bacteria persist in Intensive Care Units in hospitals.

A new understanding of an enzyme important for the transfer of genetic information in bacteria may help scientists improve current antibiotics and also create antibiotics that are less vulnerable to resistance.

Regular prescribing of antibiotics to children in the community is sufficient to sustain a high level of antibiotic resistance in the population, warn experts in a study published on bmj.com today.

University of Delaware scientists have invented a novel biomaterial with surprising antibacterial properties that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact--opening the door to the possibility of delivering a targeted payload of cells and antibiotics to repair the damaged tissue.

Scientists from the University of Havana use lobster waste to generate chitin and chitosan, two key compounds in biomedicine and agriculture.

Scientists at the University of Minnesota have been evaluating the impact of antibiotic feeding in livestock production on the environment. This particular study, funded by the United States Department of Agriculture (USDA), evaluated whether food crops accumulate antibiotics from soils spread with manure that contains antibiotics.

After a first childhood urinary tract infection (UTI), daily antibiotics may not prevent another such infection, and may actually increase the risk that the next urinary tract infection is caused by resistant bacteria, according to a new study in the July 11 issue of the Journal of the American Medical Association.

Putting bacteria on birth control could stop the spread of drug-resistant microbes, and researchers at the University of North Carolina at Chapel Hill have found a way to do just that.

Drinks containing probiotic bacteria can help reduce diarrhoea among older people, which may reduce length of stay in hospital and save the NHS money, say Imperial College researchers at Hammersmith Hospital in a study published on bmj.com today.

The search for ways to promote growth of farm animals without adding antibiotics to feed has led scientists in Taiwan to an advance toward genetically engineering animals that produce higher levels of a natural growth-promoting protein in their milk.

University of Nottingham experts have joined forces with Canadian biotech company GangaGen Life Sciences Inc to develop new weapons in the fight against food poisoning.
