Whooping cough bacterium evolves in Australia
The bacterium that causes whooping cough, Bordetella pertussis, has changed in Australia - most likely in response to the vaccine used to prevent the disease - with a possible reduced effectiveness of the vaccine as a result, a new study shows.
A UNSW-led team of researchers analysed strains of Bordetella pertussis from across Australia and found that many strains no longer produce a key surface protein called pertactin.
About 80 per cent of the 2012 whooping cough cases in Australia studied by the team were caused by pertactin-free strains.
Pertactin is one of the ...
