Fig. 3From: Phenotypic zinc resistance does not correlate with antimicrobial multi-resistance in fecal E. coli isolates of pigletsComparison of MIC values for antimicrobial resistant (R) and -susceptible isolates (S). A Mann–Whitney U test comparing 124 resistant isolates and 86 susceptible isolates (overall 210 isolates) showed no significant difference of zinc-MIC value between considered groups (P = 0.107)Back to article page
