A widespread family of chaperones functions to stabilize membrane protein effectors by mimicking transmembrane helical environments and promotes effector export by the bacterial type VI secretion system.
The basal body of the type-III secretion system of Yersinia enterocolitica within bacterial membranes shows elasticity and is longer than related isolated systems.
Microbial genetics and biophysical analyses provide insight into an evolutionarily conserved bile salt receptor complex used by pathogenic bacteria to sense their environment.
Visualization of the type III secretion mediated Salmonella-host cell interface reveals the intact translocon and the profound remodeling of the host membrane at unprecedented resolution.
Interbacterial interactions can promote mutagenesis, and possibly adaptation, when intoxicated cells survive exposure to type VI secretion-delivered DNA deaminase toxins.
Quorum-sensing control of Burkholderia thailandensis toxin and immunity pairs serves to police quorum-sensing mutants and may represent a general strategy whereby cooperators can police mutants.
Plasmodium parasites use host-derived factors to form more rosettes and hamper phagocytosis, representing a new escape mechanism for the malaria parasites.
Diverse LXG toxins delivered by the Esx pathway function as mediators of contact-dependent interbacterial antagonism within and between Gram-positive bacterial species.
Transsynaptic viral tracing reveals that neurons in the superior colliculus employ projection specific rules to the sampling of retinal inputs, directing distinct visual features to different downstream targets.
