A study on the antimicrobial resistance and fatty acid compositions of motile aeromonas isolated from ice cream samples in the city of Kirşehi̇r (Turkey)

In this study, the isolation, identification, antibiotic resistance profiles and fatty acid contents of 10 Aeromonas species bacteria samples isolated from 52 ice cream samples taken from ice cream sellers in Kırşehir. The antibiotic resistance of 3 A. caviae, 6 A. hydrophila, 1 A. sobria strain with A. hydrophila (ATCC 7966), A. veronii bv. sobria (ATCC 43979), and A. caviae (ATCC 15468) reference strains isolated as a result of the examination of the ice cream samples was determined. As a conclusion, isolated Aeromonas species bacteria samples were found to be resistant 100 % to ampicilline and tetracycline. Firstly thin layer and then gas chromatographies of the isolated samples were conducted and they were seen to be containing 12:0 (lauric acid), 14:0 (myristic acid), 15:0 (pentadecanoic acid), 15:0 3OH (3 hydroxy pentadecanoic acid), 16:1 (palmitoleic acid), 16:0 (palmitic acid), 17:1 (margaroleic acid), 17:0 3OH (3 hydroxy heptadecanoic acid), 18:1 (oleic acid) and 18:0 (stearic acid) fatty acids of A. hydrophila. key Words: Aeromonas, antibiotic resistance, fatty acid, ice cream.
