The entry of pathogens into nonphagocytic host cells has received much attention in the past three decades, revealing a vast array of strategies employed by bacteria and viruses. A method of internalization that has been extensively studied in the context of viral infections is the use of the clathrin-mediated pathway.

Ribosyl 1,5-bisphosphate (PRibP) was discovered 65 years ago and was believed to be an important intermediate in ribonucleotide metabolism, a role immediately taken over by its “big brother” phosphoribosyldiphosphate. Only recently has PRibP come back into focus as an important player in the metabolism of ribonucleotides with the discovery of the pentose bisphosphate pathway that comprises, among others, the intermediates PRibP and...

Species within the genus Burkholderia exhibit remarkable phenotypic diversity. Genomic plasticity, including genome reduction and horizontal gene transfer, has been correlated with virulence traits in several species.

Biofilms of enteric bacteria are highly complex, with multiple components that interact to fortify the biofilm matrix. Within biofilms of enteric bacteria such as Escherichia coli and Salmonella species, the main component of the biofilm is amyloid curli. Other constituents include cellulose,...
