Characterization of Vibrio parahaemolyticus isolated from Patients in Zhoushan of China
Vibrio parahaemolyticus has emerged as a common foodborne pathogen of global concern.This study collected 107 strains of V.parahaemolyticus from active surveillance hospitals in Zhoushan during 2013 to 2014 and investigated their serotypes,virulence genes(tdh,trh and ORF8),antimicrobial resistance and genotypes.The dominant serotypes of the 107 clinical strains were O3:K6,O4:K8 and O4:KUT with 87.9 and 3.7%of the strains carrying virulence genes tdh and trh,respectively.Molecular typing by pulsed-field gel electrophoresis showed divergence among the clinical strains.Analysis of resistance of the strains to antibiotics revealed high resistance of the clinical isolates to Ampicillin(100%),Piperacillin(30.84%),Cephalothin(16.82%),Cefuroxime(4.67%),Streptomycin(3.74%),Cefazolin(1.87%),Cefoxitin(1.87%),Ceftazidime(0.93%),Aztreonam(0.93%),and Kanamycin(0.93%)with 49.5%of the isolates showing resistant to two or more antibiotics grouped in 10 different resistance patterns.Ongoing surveillance of V.parahaemolyticus in diarrhea patients is a public health priority and is useful in conducting risk assessment of foodborne illnesses caused by V.parahaemolyticus.
