TWiM explains the discovery of hotspots of genetic variation containing reservoirs of anti-phage systems in E. coli phages and their parasitic satellites, and pathogen desiccation tolerance promoted by hydrophilins.
Vincent, Elio, and Michael consider a fungal pathogen of insects that acquired a gene from its host that facilitates infection, and presence of gram-negative nosocomial pathogens on community surfaces near hospitals in Brooklyn.
