Community composition and antibiotic resistance of bacteria in bottlenose dolphins Tursiops truncatus – Potential impact of 2010 BP Oil Spill

摘要: Abstract Aquatic contamination, oil spills in particular, could lead to the accumulation of antibiotic resistance by promoting selection for and/or transfer genes. However, there have been few studies on marine mammals relation environmental disturbances, specifically contaminations. Here we initiated a study bacteria bottlenose dolphins Tursiops truncatus contamination following 2010 BP Oil Spill northern Gulf Mexico. Bacterial communities and prevalence one year after were compared between Barataria Bay (BB) Sarasota (SB) applying rarefaction curve method, (generalized) linear mixed models. The results showed that most common included Vibrio, Shewanella, Bacillus Pseudomonas. was high bacterial isolates at both bays. Though diversity did not differ significantly among water or dolphin samples, samples two bays, multi-drug higher BB than SB, mainly attributed E, CF, FEP SXT. We also found sulfamethoxazole-trimethoprim-resistant Stenotrophomonas maltophilia first time natural aquatic environment. is likely as expected more urbanized bay area, would had based previous studies. data gathered this research will fill important gaps contributes broader spatial-scale emerging environments.
