Bacteria’s shape adapted to throat?
We are so informed, at ScienceDaily: Evolution moulds the shapes of living creatures according to the benefits they offer. At the microscopic level, do the various shapes of bacteria also contribute to their survival? Does a spherical bacterium (coccus) have a better chance of infecting its host than its stick-shaped neighbour (bacillus)? Analysis of the evolution of the pathogenic bacteria that live in the nasopharynx suggests that the shape of these bacteria has changed over time, shifting from bacillus to coccus. In an article published in the journal PLOS Genetics, Professor Frédéric Veyrier, of INRS-Institut Armand-Frappier Research Centre, and his colleagues demonstrate that this change may have occurred to make the bacteria better at slipping through the defences of Read More ›
