| Strains | Lineage | Source | Isolation date | ICE STX | GEN | STR | NAL | CIP | SUL | SXT | TET | CHL |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| VC18 VC19 VC21 VC25 VC66 | Afr9 | Clinical | 2008/2010 | + | S | R | S | S | R | R | S | S |
| VC23 VC62 | Afr9 | Clinical | 2007/2010 | – | S | I | S | S | S | S | S | S |
| VC64 | Afr9 | Water | 2007 | – | S | I | S | S | S | S | S | S |
| VC29 VC30 VC31 VC40 VC47 VC73 VC74 VC84 VC100 |
Afr12 | Clinical | 2008/2009/2010/2013/2015 | + | S | R | R | S | R | R | S | I |
| VC105 | Afr12 | Water | 2009 | – | S | I | R | S | S | S | S | S |

*Phenotypic resistance was determined according to Clinical and Laboratory Standards Institute breakpoints (6,7). CHL, chloramphenicol; CIP, ciprofloxacin; GEN, gentamicin; ICE, integrative and conjugative element; NAL, nalidixic acid; STR, streptomycin; SUL, sulfonamide; SXT, trimethoprim/sulfamethoxazole; TET, tetracycline; +, indicates presence of the region with antimicrobial resistance genes in ICE STX; –, indicates absence of the region with antimicrobial resistance genes in ICE STX.
