Abstract

Surveillance of antimicrobial resistance is indispensable for empirical treatment of infections and in preventing the spread of antimicrobial resistant microorganisms. This study is aimed at determining the antibiotic susceptibility of potentially pathogenic halophylic Vibrio species isolated in Lagos, Nigeria. Susceptibility patterns to ten (10) antibiotics were investigated in 44 potentially pathogenic halophilic Vibrio species isolated from sea foods in Lagos. Antimicrobial susceptibility tests showed that all the isolates (100%) were resistant to amoxicillin, augmentin, chloramphenicol and nitroforantoin. They also showed multiple resistance patterns to Gentamycin, Nitrofurantoin, Tetracycline, Augmentin, Chloramphenicol, Amoxycilin, Ofloxacin, Cotrimozazole, Ceftriazone, and Ciprofloxacin. Resistance to all ten antibiotics occurs in 8 (18%) of the isolates. Among individual sp., Vibrio harveyi was found to be most resistant to the antibiotics screened. Infection caused by Vibrio contaminating sea foods in this envinronment will be difficult to treat because of their high antibiotic resistant nature.

Key words: Vibrio species, antibiotic resistance, Lagos.
