Distribution of drug resistance among phylogenetic clades of the Ural family
| Identifiers | Number of strains (n = 149) | Susceptible and monoresistant, number (%) | Polyresistant, number (%) | MDR, number (%) | Pre-XDR and XDR, number (%) | Pre-XDR and XDR prevalence in Clades C vs A&B, χ2a; p |
|---|---|---|---|---|---|---|
| Out-of-clade strains | 27 | 9 (33.3) | 2 (7.4) | 16 (59.3) | 8 (29.6) | 65.3; < 0.0001 |
| Clade A | 31 | 26 (83.9) | 2 (6.4) | 3 (9.7) | 1 (3.2) | |
| Clade B | 52 | 28 (53.9) | 10 (19.2) | 14 (26.9) | 4 (7.7) | |
