Figure 1.

This figure shows that resistant rates of E. coli to various uroantiseptic drugs were the highest for ampicillin and TMP/SMX. During the period of observance E. coli’s resistance to TMP/SMX had significantly increasing trend, to cephalexin had significantly decreasing trend while to amoxicillin/clavulonic acid had 93% probability to have decreasing trend. Resistance rates of E. coli did not change significantly to ampicillin and to nitrofurantoin during the period of observance. Spearman’s correlation coefficient (ρ) and χ² (p) were as follows: to ampicillin (ρ=−0.120; p=0.776), to TMP/SMX (ρ=0.762; p=0.028), to cephalexin (ρ=−0.786; p=0.021), amoxicillin/clavulonic acid (ρ=−0.66; p=0.075), and to nitrofurantoin (ρ=−0.192; p=0.648).
