Abstract

The use of antibiotics is key to treating infected wounds. However, its effectiveness has begun to decrease due to the high bacterial resistance, which is caused by the phenomenon of biofilm. Therefore, it’s necessary to discover new antibacterial and antibiofilm activity agents that can be used as alternative therapies. This study aims to test the antibacterial and antibiofilm activity of black betel leaves (Piper betle L. var. nigra) ethanol extract. Antibacterial and antibiofilm activity test was conducted using the microdilution method against Staphylococcus aureus and Pseudomonas aeruginosa with concentration variations 4; 2; 1; 0.5; 0.25; and 0.125 mg/mL, also used positive control kanamycin 10 mg/mL and negative control DMSO 1%. The results showed that the black betel leaves ethanol extract had low antibacterial activity with MIC50 > 4 mg/mL for both bacteria and vigorous antibiofilm activity with MBIC50 < 0.125 mg/mL for S. aureus and MBIC = 0.491 mg/mL for P. aeruginosa. The antibacterial activity of the black betel leaves ethanol extract was lower than it’s antibiofilm activity, the antibacterial and antibiofilm activities of the black betel leaves ethanol extract were higher against S. aureus than P. aeruginosa.Keywords: Antibacterial, Antibiofilm, Piper betle L. var. nigra

Abstract

Candida albicans can cause two infections in humans: superficial and systemic. The ability of C. albicans to infect the host is influenced by virulence factors and character changes so that it can fool the immune system. From the character change factor, C. albicans can form a biofilm. This study aims to determine the good concentration in inhibiting and determine the antifungal and antibiofilm activity of nanoemulsion mouthwash formulation of bajakah tampala (Spatholobus littoralis Hassk) skin extract against C. albicans. This research was conducted with an experimental method. The formulation used a spontaneous magnetic stirrer technique to make nanoemulsion preparations. Antifungal and antibiofilm tests were carried out by dilution method using a 96-well plate and a microplate reader with a wavelength of 620 nm to determine the percentage inhibition against C. albicans and determine MIC50 and MBIC50. The results showed that the nanoemulsion mouthwash formulation of S. littoralis inhibited the planktonic and biofilm of C. albicans. The concentration of 1% is expressed as MIC50 and MBIC50. Therefore, the nanoemulsion formulation of S. littoralis extract could inhibit the growth of C. albicans in the oral cavity.
