Abstract:
This study aimed to characterize the antimicrobial susceptibility and genetic features of a heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) strain Guangzhou-SauVS2 recovered from a female patient in Guangzhou, representative of southern China. The genome of Guangzhou-SauVS2 was sequenced using Illumina HiSeq 2500 platform and assembled de novo using Velvet v1.2.08. Annotations and bioinformatics analysis were further performed. Results showed that Guangzhou-SauVS2 was susceptible and resistant to 7 and 11 antibiotic drugs, respectively, and exhibited hVISA with a minimum inhibitory concentration of vancomycin as 4 μg/mL. Its genome is 2,883,941 bp in length and contains 2934 predicted genes with an average G + C content of 32.9%. Besides, a total of 38 virulence factors and 4 antibiotic-resistant genes were identified. These results can be employed to further study the pathogenic and antimicrobial mechanisms of hVISA.
