TABLE 1 .

Resistance patterns of ESKAPE strains for different classes of antibiotics^a

^aFilled black circles indicate resistance (zone of inhibition of ≤1 mm from the edge of disk of antibiotics); the absence of a mark indicates a wider zone of inhibition. Gray boxes indicate that no test was conducted. The amount (micrograms) per disk of antibiotics (Oxoid, BBL) is indicated in parentheses. Colistin and polymyxin B, polypeptides active against only Gram-negative bacteria, were also tested on K. pneumoniae, A. baumannii, P. aeruginosa, and Enterobacter spp.; no resistance was observed. Superscript numerals indicate strains identified by 16S rRNA gene sequences (accession numbers are KT827400, KT827398, and KT827399 for strains marked by numerals 1, 2, and 3, respectively).
