Antibiotic Resistance and Virulence Profiles of Gram-Negative Bacteria Isolated from Loggerhead Sea Turtles ( Caretta caretta ) of the Island of Maio, Cape Verde
Previous studies revealed high levels of antimicrobial resistance (AMR) in loggerhead sea turtles ( Caretta caretta ), describing this species as prime reservoir of antimicrobial-resistant bacteria. This study aimed to characterise, for the first time, the AMR and virulence profiles of Gram-negative...
