Table 5. Covariation of resistance between ceftazidime and 6 other antibiotics.
Covariation is given as agreement on resistance and susceptibility, respectively, between ceftazidime and one other agent at the time. (100% = full agreement). Four different groups of gram-negative bacteria. Paediatric patients.
| Non-Klebsiella Enterobacteriaceae | Klebsiella spp. | Pseudomonas spp. | Acinetobacter spp. | All | ||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Ceftazidime (Number of isolates) | R = 18 | S = 11 | R = 29 | S = 5 | R = 6 | S = 5 | R = 11 | S = 7 | R = 64 | S = 28 |
| Gentamicin | 83% | 100% | 93% | 20% | 83% | 100% | 64% | 100% | 84% | 85% |
| Chloramphenicol | 44% | 100% | 76% | 75% | 83% | 20% | 91% | 72% | 71% | 74% |
| Tetracyclin | 89% | 36% | 88% | 60% | 67% | 80% | 64% | 67% | 82% | 56% |
| Co-trimoxazole | 94% | 73% | 83% | 60% | 50% | 80% | 80% | 86% | 82% | 75% |
