Erythromycin Resistance in Streptococcus pyogenes in Italy
Table 2
Frequency of clarithromycin failure, by susceptibility profile
Patients treated (no.) | Treatment failed (%) | p value | |
---|---|---|---|
Erythromycin-susceptible | 25 | 3 (12) | |
Erythromycin-resistant | 19 | 7 (36.8) | 0.07a |
- CRb | 6 | 6 (100) | 0.0001a |
- other phenotypes | 13 | 1 (7.6) | 1.0a; 0.0002c |
Total | 44 | 10 (22.7) |
aFor comparison of percentage of failure with erythromycin-susceptible.
bCR = Constitutive-type resistance.
cFor comparison of percentage of failure between CR and other phenotypes of resistance.
