Characterised ETEC strains collected from Bolivian children with diarrhoea 2002–2009 organised with respect to genetic distance according to the MLST analysis and time of isolation within each sequence type.

aCS21 within brackets: positive for CS21 by PCR but negative in dot-blot.bNT = Non typeable, HNM = nonmotile.cResistant to AMP = Ampicillin, AMPS = Amp-Sulbactam, CIP = Ciprofloxacin, CLOR = Chloramphenicol, GEN = Gentamicin, NAL = Nalidixic Acid, CEF = Cefoxitine.TSX = Trimethoprim sulfamethoxazole, TET = Tetracyclin.dnt = not tested.eAccording to National Committee for Clinical Laboratory Standards for Antimicrobial Disk Susceptibility.fNd = not determined due to an initial co-infection of two strains in each patient; LT/CS17 and STh/CS6 strains were isolated, the LT CS17 strains persisted and were analysed in this study but we cannot rule out that the antibiotics profiling was performed on either or both strains at the time of testing.
