Treatment for a deadly E. coli strain may be possible, after UNSW Sydney researchers identified a new molecular pathway that controls the potent Shiga toxin.
Whooping cough bacteria are becoming smarter at colonising and feeding off unwitting hosts, strengthening calls for a new vaccine, according to UNSW researchers.
In a case of sophisticated scientific sleuthing, a UNSW researcher has helped pin down the source of an unprecedented outbreak of streptococcal disease in China.
The bacterium that causes whooping cough has evolved – 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.
Vaccination programs against whooping cough may not be fully effective because the bacteria that cause the disease have mutated, a UNSW study has found.
