Comparative study on isolation of r-plasmids from ampicillin resistant isolates of caries and non-caries patients


S Karikalan, A Mohankumar

The oral bacterial isolates have been multi-drug resistant in tradition for several decades and specific antibiotic was resistant to caries pathogens. The aim of the present study was to prove the Ampicillin antibiotic completely resistant to oral isolate and a comparative study about the R- plasmid isolated from caries causing, Ampicillin resistant bacteria Streptococcus mutans. The samples were collected from caries and non-caries patients. The extracted tooth and the saliva samples were collected from them. The effectivity of caries was determined by the caries susceptibility test. S.mutans the predominant cariogens were isolated and R-plasmids were isolated from oral pathogen and compare with caries and without caries isolates. Antibiogram of S.mutans, Ampicillin showed 100% resistant. The main objective of this study was assessed the isolation of R- plasmids from dental caries causing, Ampicillin resistant isolate of S. mutans from the caries and non-caries patients.
