title: Antibiotic resistance profiling and phenotyping ofAeromonasspecies isolated from aquatic sources.
abstract: This study aimed to investigate antibiotics resistance pattern and phenotyping ofAeromonasspecies isolated from different aquatic sources in Melaka, Malaysia. A total of 53Aeromonasspecies were isolated from the following sources: sediment (n= 13), bivalve (n= 10), sea cucumber (n= 16) and sea water (n= 14) and resistance to 12 antibiotics - Tetracycline (30 μg), Kanamycin (30 μg), Oxytetracycline (30 μg), Ampicillin (10 μg), Streptomycin (10 μg), Gentamicin (10 μg), Sulphamethoxazole (25 μg), Nalixidic acid (30 μg), Trimethoprim (1.25 μg), Novobiocin (5 μg), Penicilin (10 μg) and Chloramphenicol (10 μg) was tested. The results obtained from this study reveal multi drug resistance pattern among the isolates. All the isolates were completely resistant to Ampicillin, Novobiocin, Sulphamethoxazole and Trimethoprim, respectively but susceptible to Tetracycline (100%), Kanamycin (5.7%), Gentamicin (5.7%) and Oxytetracycline (24.5%). Antibiotics phenotyping of the bacteria revealed 21 different phenotypes among the isolates.
