Table 1.
Distribution of MSSA and MRSA isolates and their predominant spa types in cities throughout China.
Table 2.
Summary statistics of patients and spa typing for MSSA/MRSA isolated in seven hospitals.
Table 3.
The prevalence of MRSA, PVL and predominant spa types among different isolate sources.
Figure 1.
Population snapshot of 318 Staphylococcus aureus isolates described in the current study, using the results of spa typing.
Clusters of linked isolates correspond to clonal complexes by means of the BURP algorithm. Primary founders (in blue) are positioned centrally in the cluster. The highlighted numbers indicate spa types identified in the MRSA populations.
Table 4.
The first five spa types, antibiotic resistance profile, virulence gene profile and distribution by city among MRSA and MSSA isolates.
Table 5.
The distribution of MLST types, SCCmec types and virulence genes in different MRSA clones according to spa clone complex.
Figure 2.
The comparisons of antibiotics resistance of epidemic MRSA clones (corresponding to ST239) and non-epidemic MRSA clones with MSSA isolates.
Chi-square test and Fisher's exact test were used for comparison. P, penicillin; E, erythromycin; CLI, clindamycin; RIF, rifampin; CIP, ciprofloxacin; GM, gentamicin; TET, tetracycline; SXT, trimethoprim-sulfamethoxazole, FD, flusidic acid. * P<0.05.
