Aims: To determine if the seaweed (C.lentillifera) has an anti-microbial activity against the opportunistic pathogenic yeast, Candida albicans.
Study Design: In this study, experimental method was used by the researchers.
Place and Duration of the Study: University of Perpetual Help-Dr. Jose G. Tamayo Medical University between May 2018 and November 2018.
Methodology: The researchers performed Kirby Bauer Disc Diffusion Method. The seaweed (C. lentillifera) was divided into different concentrations, isolated C. albicans, and Fluconazole as the positive control were used in the study. The zone of inhibition was observed and measured after 16-18 hours of incubation.
Results: The process yield to different results in different concentration. On the first concentration, 25% revealed 6mm of zone inhibition on 5 (five) plates containing C. albicans. 50% concentration of plates with with C. albicans gave 6mm of zone of inhibition. 75% concentration of 5 plates with C. albicans gave 6mm zone of inhibition. The last concentration, 100%, the plates containing C. albicans gave 6mm concentration on all plates.
Conclusion: The researchers derived that the extract of C. lentillifera (lato) showed resistance because no zone of inhibition was shown to all concentrations when placed on the plates containing C. albicans. Results showed that the C. lentillifera is resistant to the opportunistic pathogenic yeast, C. albicans.
