Genetic resistance determinants among fusidic acid-resistant isolates
| Prevalence [count (%)]a |
||||
|---|---|---|---|---|
| total (n = 56) | LS (n = 21) | NLS (n = 15) | anterior nares (n = 20) | |
| fusA mutations | 21 (38) | 9 (43) | 6 (40) | 6 (30) |
| fusE mutations | 3 (5) | 1 (5) | 1 (7) | 1 (5) |
| fusB geneb | 3 (5) | 1 (5) | 1 (7) | 1 (5) |
| fusC geneb | 32 (57) | 11 (52) | 8 (53) | 13 (65) |
a
Three isolates had mutation in both fusA and fusE; thus, the sum of the prevalence count of the four genetic determinants exceeds the total count of resistant isolates.
b
All isolates had genes with 100% identity and 100% coverage to reference genes, with the exception of fusC in one isolate (100% identity, >95% coverage).
