The Effect Of Gamma Irradiation On Salmonella Chester Aand Its Sensitivity To Antibiotics

The sensitivity changes of Salmonella chester (S.chester) to antibiotics as the results of gaInlna iiradiation has not much been studied. To undesrstand the sensitivity cganges of S.chester to several antibiotics as the results of gamma irradiation with the doses of 1.0; 2.5 and 5.0 kGy, an ivestigation was carried out using resubculture method.
The irradiation effescts was evaluated by using Complete Randomized Design with factorial pattern and the data processing by Analyses of Variance and Duincan test. It revealed that after irradiation wit doses of 1.0 and 2.5 kGy, S.chester more sensitive to antibiotics Amphycillin, Tetracyclin and Chlormnphenicol. It was also found that using different media culture during irradiation, the sensitivity of S.chester to antibiotics was also different. (By. T.
