STUDY OF ANTAGONISTIC INTERACTIONS BETWEEN SERRATIA MARCESCENS AND PSEUDOMONAS PUTIDA AND THEIR ANTIBIOTIC SUSCEPTIBILITY
This study investigated the antagonistic relationships and antibiotic susceptibility of Serratia marcescens and Pseudomonas
putida. Using the dual-culture cross-streak method, the experiments revealed no significant antagonistic effects between the two
strains. When assessing antibiotic susceptibility via the disk diffusion method, high sensitivity to tetracycline was observed,
while resistance to ampicillin was confirmed. The results highlight the impact of antibiotics on bacterial growth and metabolic
activity, contributing to the understanding of coexistence processes.
