Abstract:
A patient was admitted to hospital due to umbilical pain.Gram-staining presented short,positive coc-cobacillus in the purulent secretions from the umbilical cord of the patient.Meanwhile,matrix-assisted laser desorp-tion/ionization time-of-flight mass spectrometry(MALDI-TOF MS),16S rRNA detection,and in vitro antimicro-bial susceptibility testing were performed on the isolated strains.Corynebacterium tuberculostearicum was identified by Gram-staining,MALDI-TOF MS and 16S rRNA.Antimicrobial susceptibility testing results showed that the strain was sensitive to penicillin,ceftriaxone,cefepime,meropenem,vancomycin,daptomycin,linezolid,compound sulfamethoxazole,ampicillin,gentamicin and tetracycline.Smear of microorganisms is helpful for the identification of Corynebacterium tuberculostearicum morphology,and MALDI-TOF MS is necessary for rapid identification of strains.Antimicrobial susceptibility testing can also assist the empirical treatment for infection due to this strain.
