The MIC of capsaicin on Actinomyces viscosus was 50ug/ml.
In our study, capsaicin was used to evaluate the antimicrobial property on the inhibition of acid producing and biofilm of Streptococcus mutans, Actinomyces viscosus, Lactobacillus and Streptococcus sanguis, which were sectional cariogenic bacteria, in order to search for new antimicrobial agents or treatment methods to cure or prevent dental caries.
Although antibacterial activity of capsaicin on Streptococcus mutans, Actinomyces viscosus, Lactobacillus and Streptococcus sanguis were proved in this study, the effects of capsaicin on internal relation among these bacteria should be lucubrated in later investigations, because that caries are not caused by single bacteria but multiple effects of various bacteria (Yu et al., 2017).
The present work selected four strains of cariogenic bacteria (Streptococcus mutans, Actinomyces viscosus, Lactobacillus and Streptococcus sanguis) as research objects.
Fueron sembrados: Streptococcus mutans en agar TSA, Lactobacillus acidophilus en agar Rogosa y, en los casos de Actinomyces viscosus, Prevotella melaninogenica y Fusobacterium nucleatum en Agar Shadler suplementado con sangre de cordero al 5 %
En las Figuras 2, 3, 4 y 5 se observa dicha actividad pero sobre las bacterias Lactobacillus acidophilus, Actinomyces viscosus, Prevotella melaninogenica y Fusobacterium nucleatum respectivamente.
truxillense (coca Trujillo) y Camellia sinensis (te verde) en concentraciones de 25 y 50 [micron]g/mL, demostraron tener propiedades antibacterianas in vitro sobre cepas de bacterias patogenas orales como: Streptococcus mutans, Lactobacillus acidophilus, Actinomyces viscosus, Prevotella melaninogenica y Fusobacterium nucleatum que conforman parte de la microbiota bucal y estan implicadas en patologias orales como caries dental y enfermedad periodontal.
Los tres extractos hidroalcoholicos en las diluciones de 25 y 50 [micron]g/mL presentaron actividad antibacteriana sobre Streptococcus mutans, Lactobacillus aci dophilus, Actinomyces viscosus, Prevotella melaninogenica y Fusobacterium nucleatum.
Se determino la presencia o no de Actinomyces viscosus, y de la cantidad de este aislada del medio de cultivo, siguiendo el mismo parametro que para la de Actinomyces sp.
Para hacer el cultivo se tomo el cono de papel y el hisopo y se procedio a sembrar en un medio de tioglicolato, para anaerobios y se dejo incubar durante 14 dias; posterior a ello se hizo el repique en Agar Sangre para anerobios CDC para permitir el aislamiento optimo de los Actinomyces sp; se identificaron macroscopicamente las colonias de Actinomyces sp que cumplieran con los siguientes criterios: Colonias medianas lisas, blanquecinas, y se identifico la presencia de Actinomyces viscosus mediante cepa referencia para Actinomyces ATCC 15987.
Ademas, se utilizo la coloracion de Gram para confirmar morfologia bacilar y se practico la prueba bioquimica de catalasa para confirmar la presencia de Actinomyces viscosus.
(2,3) The specific etiologic agents include Actinomyces israelii, Actinomyces naeslundii, Actinomyces odontolyticus, and Actinomyces viscosus. (1,2) A odontolyticus and A viscosus are more often associated with dental caries.
