Table 5. Multidrug resistance pattern of ESBL producing and non-ESBL producing E. coli and K. pneumoniae isolates.
| Isolates | Level of antibiotics resistance ((number (%)) | MDR (≥R3) | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| R0 | R1 | R2 | R3 | R4 | R5 | R6 | ≥R7 | |||
| ESBL positive | E. coli (n = 39) | 0 (0.0) | 1 (2.6) | 1 (2.6) | 3 (7.7) | 3 (7.7) | 10 (25.6) | 10 (25.6) | 11 (28.2) | 37 (94.9) |
| K. pneumonia (n = 8) | 0 (0.0) | 0 (0.0) | 1 (12.5) | 1 (12.5) | 0 (0.0) | 1 (12.5) | 0 (0.0) | 5 (62.5) | 7 (87.5) | |
| ESBL negative | E. coli (n = 185) | 42 (22.7) | 11 (5.9) | 20 (10.8) | 26 (14.1) | 62 (33.5) | 22 (11.9) | 1 (0.5) | 1 (0.5) | 112 (60.5) |
| K. pneumonia (n = 31) | 0 (0.0) | 9 (29.0) | 6 (19.4) | 6 (19.4) | 8 (25.8) | 2 (6.5) | 0 (0.0) | 0 (0.0) | 16 (51.6) | |
| Total (N = 263) | 42 (16.0) | 21 (8.0) | 28 (10.6) | 36 (13.7) | 73 (27.8) | 35 (13.3) | 11 (4.2) | 17 (6.5) | 172 (65.4) | |
R0: resistance to no antibiotics, R1-6: resistance to 1, 2, 3, 4, 5, and 6, ≥R7: resistance to ≥7 antibiotics; MDR: Multidrug resistance.
MDR (≥R3): resistance to 3 or more antibiotics from different classes.
