New research from the Institute of Food Research has mapped chromosomes of Campylobacter. Scientists are trying to understand how this pathogenic bacteria controls its genes to develop new strategies to fight it. In the UK, Campylobacter is the most common cause of foodborne diarrheal illness.
The chromosome map shows where all of the bacteria turns on its genes. Those are called transcriptional start sites (TSS). The bacteria turns on different genes in response to changes in its environment. TSS are also how the bacteria evolved to adapt to new situations. All organisms have these control mechanisms.
