Objective: To evaluate in vitro the antibacterial effect of the methanolic extract of Malvaviscus penduliflorus (Malvavisco) and Desmodium molliculum (Manayupa) against strains of Streptococcus sanguinis (ATCC® 10556) y Porphyromonas gingivalis (ATCC® 33277TM). Material and methods: The present study was experimental in vitro. The methanolic extract of Manayupa and Malvavisco was prepared. Subsequently, the extracts were independently added to 13 Petri dishes containing the bacterial strains. The antibacterial effect was evaluated with the Kirby Bauer method. Whereas the MIC and MBC were found using the microdilution method, and the CC50 was evaluated through the MTT method. Result: A greater antibacterial effect was found in the P. gingivalis strains by the Malvavisco extract, which presented inhibition halos of 17.83 mm + S.D 0.75. Whereas, Manayupa presents inhibition halos of 17.25 mm + S.D 0.93 with the Manayupa. Likewise, in the S. sanguinis strains, the inhibition halos obtained with the Malvavisco extract were 15.25 mm + D.S 0.27 S.D and 15.16 mm + D.S 0.60 by the Manayupa. Finally, the cell viability found in both methanolic extracts showed that at concentrations lower than 50 mg/ml there is less cytotoxicity. Conclusion: There is an antibacterial effect of the methanolic extract of Malvaviscus penduliflorus (Malvavisco) and Desmodium molliculum (Manayupa) on strains of Streptococcus sanguinis (ATCC® 10556) y Porphyromonas gingivalis (ATCC® 33277TM).
