Antibiotic resistance of gram negatif bacteria isolated from farming lands

The proposed study determines the antibiotic resistance phenotypes and MAR indexes of 150 types of Gram (-) bacteria, isolated from four different areas according to their frequencies of cultivation (frequent cultivation, infrequent cultivation, uncultivated fields and greenhouse cultivation areas) and identifies 102 types.The antibiotic resistance rate of bacteria isolated from frequently cultivated fields, infrequently cultivated fields, uncultivated fields and greenhouse cultivation areas were found to be 38,13%, 16,83%, 26,64% and 22,83% respectively and a statistically significant difference was observed only between frequently cultivated fields and infrequently cultivated fields.It was observed that the highest MAR index in frequently cultivated fields was 0,73 with 8 bacteria, 0,67 in infrequently cultivated fields with 1 bacteria, 0,67 in uncultivated fields with 3 bacteria, and 0,73 in greenhouse cultivation fields with 1 bacteria. It was also found out that 29 bacteria in frequently cultivated fields, 18 bacteria from infrequently cultivated fields, 16 bacteria from uncultivated fields and 28 bacteria from greenhouse cultivation areas were resistant to more than one type of antibiotics.
