Protection against 2009 influenza H1N1 by immunization with 1918-like and classical swine viruses

Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...

A new theory of how low doses of antibioitics create antibiotic resistance

Exposure to low levels of antibiotics increases mutations in E. coli and Staphylococcus bacteria hundreds of time more than normal, making the creation of drug-resistance strains more likely, says a paper in today's edition of the journal Molecular Cell.

This finding adds to concerns about an... Read More

A land apart: Are the bugs in wild animals resistant to antibiotics?

BACTERIA that are resistant to antibiotics are becoming disturbingly common in people. More worrying still is that the genes which confer this resistance are also showing up in bacteria found in other animals. When resistant bacteria hop between species, that can increase the rate of evolution a... Read More
