Genetic characteristics: Two serovar Kiambu isolates (were found to possess genomic island SGI1. SRC10 and SRC11 ) exhibited resistance to all antibiotics in the standard SGI1-containing DT104 set (Ap, Cm and Fl, Sm and Sp, Su, and Tc). These two isolates with two cassettes (aadA2 and blaP1) were additionally resistant to trimethoprim and also possessed dfrA10 and CR1.
