Escherichia coli research studies

Urinary tract infections (UTIs) pose a severe public health problem and are caused by a range of pathogens. In this Review, Hultgren and colleagues discuss how basic science studies are elucidating the molecular mechanisms of UTI pathogenesis and how this knowledge is being used for the development of novel clinical treatments for UTIs. Urinary tract infections (UTIs) are a severe public health problem and are caused by a range of pathogens, but most commonly by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Enterococcus faecalis and Staphylococcus saprophyticus. High recurrence rates and increasing antimicrobial resistance among uropathogens threaten to greatly increase the economic burden of these infections. In this Review, we discuss how basic science studies are elucidating the molecular details of the crosstalk that occurs at the host–pathogen interface, as well as the consequences of these interactions for the pathophysiology of UTIs. We also describe current efforts to translate this knowledge into new clinical treatments for UTIs.
