Characterization of Vibrio parahaemolyticus strains and evaluation of shrimp cultivation conditions in a farm at the northwestern of Mexico, as risk predictors for its adaptation and dissemination

Vibrio parahaemolyticus is recognized as a human pathogen well the causative agent of vibriosis in shrimp. This study determined pathogenic, antimicrobial, and biotic potential V. isolated from white shrimp (Penaeus vannamei) seawater on northwestern Mexico farm. A total 140 samples were randomly collected, including juvenile organisms (n = 120) 20). The pH, salinity, biota ponds used to correlate with bacterium presence. strains characterized by virulence genes presence, biofilm formation capacity, antimicrobial sensitivity, kinetics growth using PCR, microplates method, minimum inhibitory concentration (MIC), spectrophotometry, respectively. was detected 7.1% mean 3.72 ± 1.24 log CFU mL-1; 6.7% (8/120) 10.0% (2/20) seawater. Cultivation conditions not predictive specie (P > 0.05). showed an adaptation time 1.0 h, rate 0.375 h-1 at 30ºC. classified into two pathotypes: tlh+/tdh-/trh-/AP2- (75%) tlh+/tdh-/trh-/AP2+ (25%) three resistant profiles clinical drugs (ampicillin, amikacin, gentamicin, netilmicin). MIC values against oxytetracycline (OTC), florfenicol (FFC) enrofloxacin (ENRO) >0.50, >0.25 >0.06 ?g mL-1, Biofilm property identified 40% strains. presence infectious high adaptative justifies integrating integrated aquaculture practices management control health.
