ABSTRACT

Objective To analyze the PCR and molecular characters of the first serogroup W135 meningo-coccal death case in Shanxi province on April,2013.Methods Epidemiological survey of suspected epidemic cere-brospinal meningitis case was conducted,blood serum and petechia tissue fluid samples were identified by PCR for crgA gene and siaD gene of W 135.Multilocus sequence typing(MLST)was performed for determining the sequence types(STs).Results The patient in the case died of serogroup W135 Neisseria meningitides,which belonged to ST-11.Conclusion This is the first case died of serogroup W135 Neisseria meningitidis in Shanxi province,which prompts that the surveillance of meningococcal pathogeny should be strengthened.
