Abstract:
Objective To identify Mycobacterium abscessus rapidly with HAIN molecular assay genotype kit、gene chip and hsp65 gene sequencing,and to assess the clinical value of these three methods.Methods 13 clinical non-tuberculous Mycobacterium (NTM) of in-patient samples were collected from January2014 to January 2015,in the Department of Clinical Laboratory,Yinzhou People's Hospital,and meanwhile,these strains were identified with HAIN molecular assay genotype Mycobacterium kit and gene chip respectively.The hsp65 gene sequencing was used as the standard method to be compared with HAIN and gene chip.Results The results of HAIN kit and hsp65 gene sequencing showed that all the 13 strains were subspecies Mycobacterium abscessus,while that of gene chip showed that these strains were Mycobacteriumchelonae complex strains,and the subtypescould not be identified.Conclusion These results obtained from the HAIN molecular assay genotype mycobacterium system are in agreement with those obtained from the hsp65 gene sequencing,whereas the HAIN kit method is easier to use.
