(Phys.org) —Actin "comets" are scaffolds of polymer that various bacteria and viruses construct within cells. Party-crashers, like Listeria or Shigella bacteria, are able to seed structures using special patches of their ...
Bacteria of the genus Shigella, closely related to the well-known Escherichia coli, are the second most common cause of fatal bacterial diarrheal diseases, with over 200,000 victims worldwide every year. There are repeated ...
