Microbiological Evaluation and Antibacterial Properties of Toothpaste

Abstract

The Present study was carriedout to assess the microbiological properties & evaluation of antibacterial propertiesof toothpaste. Four branded toothpaste were purchased from the market and transfered to the laoratory for microbiological examination & antibacterial properties as to study. The assessment perform viablemicrobial count like Standred Plate Count ,isolation of pathogens on selective media. gramstaining endospore staining, Biochemical test, enzyme test antibiotic test by disc diffusion method etc. Standred Plate Count shows bacterial growth on some sample & coliforms growth. Pathogenic microbes S. aureus & E.coli were isolated in some samples. Antibiotic sensitivity test by disc diffussion method shows the clear zone of inhibition on EMB & MSA. That indicates the extent of the test organism is inability to survive in the presence of test antibiotic.
