Bilung LM, Radu S, Bahaman AR, Rahim RA, Napis S, Apun K, Queen CY, Marlina K,  Tanil GB, Nishibuchi M., Antibiotic resistance and plasmid Vibrio para-hemolyticus from cockles, Onl J Vet Res., 28(5): 294-301, 2024. We report incidence of V. para-hemolyticus in 100 cockles from Malaysian peninsula. By PCR we found 62 with Vibrio para-hemolyticus screened for tdh and trh gene resistance 0.58 to 0.94 with 89% hosting one to three 2.7 to 54kb sized plasmids. We tested carbenicillin, ceftriaxone, cephalothin, chloramphenicol, clindamycin, doxycycline, imipenem,  nalidixic acid, netilmicin, nitrofurantoine), norfloxacin, oflaxacin, rifampin, streptomycin, sulfamethixazole, teicoplanin and tobramycin finding 100% resistance to nearly all except ceftriaxone (85%), imipenem (79%), netilmicin (74%), nitrofurantoine (63%), doxycycline (60%), nalidixic acid (60%), chloramphenicol (24%) but norfloxacin only 2%. All strains of V. para-hemolyticus plasmids from cockles showed multiple antibiotic resistance (MAR) but none were predictive of antibiotic susceptibility.


Key Words: Vibrio para-hemolyticus, cockles, antibiotics, susceptibility.
