Outsmarting the smartie bug

New tools in the fight against pneumococci ?the bugs targeted by vaccines recently announced by the Department of Health ?are described by a team led by scientists from the Wellcome Trust Sanger Institute. They have put together a complete description of the targets of the vaccine that will help monitor the disease and provide new tools for rapid diagnosis.

Pneumococci (formal name Streptococcus pneumoniae) are widespread, causing non-invasive disease, such as ear and sinus infections, and rarer, invasive disease, such as pneumonia and meningitis. About one in three children each year has an ear infection, of which about one-third will be due to the pneumococcus. More significantly, invasive disease is a major cause of death: around 1 million people, mostly young children in developing countries, die each year.

The research, published online today in PLoS Genetics, shows how the target of the vaccines, called the polysaccharide capsule, has evolved and allows the researchers to determine functions of the genes involved. The polysaccharide capsule forms a sugary coat around the bacterium and changing the structure of the capsule can help it to fool our immune defence systems ?like a Smartie changing its colour.

"The bug has a polysaccharide coat which can take any one of 90 different forms, known as serotypes," said Stephen Bentley, leader of the project at the Wellcome Trust Sanger Institute. "The coat is essential for its ability to cause disease and its interaction with our immune system and some serotypes are more likely to be associated with disease."

"The current vaccines provide excellent protection against pneumococcal disease, but only that caused by some of the 90 serotypes, and it is important that we keep a watch on the development of this organism. Our work in describing all known variants will help in that surveillance"

Two vaccines are available. The first, PCV, recognizes seven forms of the capsule and protec
