Abstract: To investigate the changes of the antimicrobial susceptibility of Vibrio parahaemolyticus isolated from the pond water of shrimp larvae inGuangdong coastal from 2010 to 2012 to offer the date for the diseaseprevention of shrimp larvaeduring the breeding period. Methods: According to GB/T4789.7-200 Vibrio parahaemolyticusstrains isolated from different regions were isolated and identified.Microbial sensitivity tests were performed with the Kirby-Bauer method. Results: Among the 72 Green Vibrio strains isolated from the pond water,30strains (41.7%) were Vibrio parahaemolyticus.The susceptibilities of the 30 strains to 60 kinds of antibiotics were tested,to penicillin, ampicillin, benzene, minocycline, amoxicillin azole penicillin, tetracycline, azlocillin showed highly resistant, prevalence of tetracycline resistance as high as 97%.Conclusion:green vibrio from the pond water of shrimp larvae mainly wereVibrio parahaemolyticus, all strains resistance is strong, should enhance the regulationsof using antibiotics during the breeding period.
