Abstract:
Objective To investigate the species and antimicrobial sensitivity of marine bacteria off the Yellow and Bohai Seas of China.Methods One hundred and forty-four samples from the Yellow and Bohai Seas were collected for culture.Single colony was chosen for microbial identification with the VITEK full automatic microbial detector (VITEK AMS),the API system and the BIOMIC Vision detector,and then antimicrobial sensitivity analysis was made accordingly.Results One hundred and ninety strains were isolated from 144 seawater samples,including 78 strains of vibrios (41.05％),23 strains of enterobacteria (12.10％),82 strains of nonfermenters (43.16％),5 strains of enterococcus (2.63％) and 2 strains of fungi (1.05％).Sensitivity tests showed that various strains of bacteria were universally more sensitive to Imipenem,Cefepime,Cefiazidime,Levofloxacin and Tetracycline (＞ 90％) in the 23 antibiotics,indicating that they could be subsequently selected as the first-choice antibiotics,while those strains were less sensitive to Piperacillin,SMZ,Cefuroxime,Cefoperazone and Ampicillin (＜ 60％),which should be applied cautiously or avoided.Other antibiotics with a sensitivity of 60％-90％ were defined as alternative antibiotics.Conclusions Through the study,we have established a basic database of bacterial spectrum in the Yellow and Bohai Seas and antimicrobial sensitivity,which will provide theoretical evidence for early-stage prevention and treatment of traumas or accidental injuries sustained during marine operations.
