Characterization of Vibrio vulnificus isolated from retail cockle and shrimp by plasmid profiling and antibiotic susceptibility test

Of the 148 cockle (Anadara granosa) and 433 shrimp (Paneus indicus) samples examined, 27% and 6.9% were positive for Vibrio vulnificus, respectively. Twenty-nine and 21 isolates from cockles and shrimps were examined for their antibiotic resistance. All isolates showed resistance to one or more of t...
