TWiM explains how bacterial symbionts regulate tick blood feeding activity, and the reasons why antibiotics exist.
TWiM discusses antigenic variation within dengue virus serotypes, and an mRNA vaccine that induces antibodies against tick proteins and prevents transmission of the Lyme disease agent.
The TWiM crew ponders the question of how a bacterium finds its middle when dividing, then divulge the transfer of interbacterial antagonism genes to eukaryotes, where they may function in innate defense.
Vincent, Michele, and Michael discuss how a gene from bacteria protects a tick from plant cyanide poisoning, and enhanced transmission of Streptococcus pneumoniae by influenza virus co-infection in mice.
