Immune cells predict outcome of West Nile virus infection
Infection with West Nile virus (WNV) causes no symptoms in most people. However, it can cause fever, meningitis and encephalitis. Philip Norris and colleagues, at the Blood Systems Research Institute, San Francisco, now report that levels of immune cells known as Tregs (immune cells that suppress the function of other immune cells) in the blood of a human or mouse infected with WNV predict whether the person or mouse will have symptoms of infection. (2009-10-12)

Impact of protective bacteria linked to infection route, study finds
The benefits of protective bacteria -- which safeguard organisms from further disease without causing harm -- depend on how subsequent infections enter the body, a study of fruit flies has shown. (2017-06-06)

Analysis illuminates risk connection of herpes virus, HIV
Most people at greater risk of acquiring HIV don't know it. Most people who have HSV-2, the virus responsible for genital herpes, are unaware of the condition that dramatically increases their risk of acquiring HIV. Limiting diagnostic and therapeutic efforts to bacterial STDs - and excluding viral STDs - may not be enough to curb HIV acquisition. A metanalysis found higher risk in people with HSV-2 antibodies, and not necessarily the symptoms of genital herpes. (2001-12-21)

Backstabbing bacteria: A new treatment for infection?
Selfish bacterial cells that act in their own interests and do not cooperate with their infection-causing colleagues can actually reduce the severity of infection. The selfish behaviour of these uncooperative bacteria could be exploited to treat antibiotic-resistant infections, according to research being presented at the Society for General Microbiology's autumn meeting today. (2010-09-05)

First UK cases of previously rare disease reported in gay men
