Fosfomycin tromethamine is a phosphonic acid bactericidal agent with in vitro activity against most urinary tract pathogens. It is particularly active against Escherichia coli, and Citrobacter, Enterobacter, Klebsiella, Serratia and Enterococcus spp. There appears to be little cross-resistance between fosfomycin
