Demographic data and relevant characteristics for collection A strains.

R, resistant; HLR, high level resistant; NT, not tested; ND, not detected, S, serine; I, isoleucine; R, arginine.All isolates were susceptible to teicoplanin, resistant to ampicillin and high level resistant to ciprofloxacin in addition to the resistance profile shown in this table.aA 97% threshold similarity value of Dice dendrogram was used to designate PFGE subtype (small letter).bAll isolates were positive for esp, srgA, efaAfm, acm, scm, pilB, orf2010 and orf2514 by PCR in addition to the virulence gene results shown in this table. All isolates were also positive for pilA and ecbA with pilA 2 and ecbA 2 primers.
