The target was evaluate the “in vitro” antibacterial effect about five peruvian propolis on strains of Streptococcus mutans (ATCC 25175) and Streptococcus sanguinis (ATCC 10556), Having an experimental study design “in vitro” made in laboratorie of Microbiology of the Peruvian University of Applied Sciences. Materials and Methods: Sample size were about ten holes for each of the five extracts of propolis, either for Streptococcus mutans and Streptococcus sanguinis individualy. The antibacterial effect was developed with the technical “Agar overlay interference test”, which is used 200ml of Agar BHI homogenized with bacteria indispensably (a bottle for bacteria). This agar is distributed in the plates, once solidified the holes are made with 150μL of different kinds of propolis and the control group called Clorhexidine 0.12%. Completed this process is placed in the anaerobiosis chamber on 37º C, for 72 hours. Finally, the measurement of the inhibitory halo is made. Results: The methanolic extract of propolis of Oxapampa-Perú present inhibition halos in larger averaging of 33.15 + 3.26 mm against strains of Streptococcus mutans (ATCC 25175) and Streptococcus sanguinis (ATCC 10556), their average was about 23.23 + 0.82mm. In case of 4 extracts of commercial, just 3 of them (tincture of propolis Farmagel, Madre Nature y Kaita®), had bacterian activity in front of the studies strains. In all cases the antibacterian activity is less than positive control. Conclusions: The methanolic extract of propolis of Oxapampa-Peru, made in the laboratory has better antibacterian activity than commercial extracts against strains of Streptococcus mutans (ATTC 25175) and Streptococcus sanguinis (ATCC 10556). About the four commercial propolis evaluated on this study, propolis tincture Farmagel, Kaita®, Madre Natura and Max propolis tincture, only three of this have antibacterial activity against strains of de Streptococcus mutants (ATCC 25175) and Streptococcus sanguinis (ATCC 10556). / El objetivo fue evaluar in vitro el efecto antibacteriano de cinco propóleos peruanos sobre cepas de Streptococcus mutans (ATCC 25175) y Streptococcus sanguinis (ATCC 10556) teniendo un diseño de estudio experimental in vitro, realizado en el laboratorio de Microbiología de la Universidad Peruana de Ciencias Aplicadas. Materiales y métodos: se comparó el efecto antibacteriano de cuatro marcas comerciales de propóleo Tintura de propóleo Farmagel, Tintura de propóleo Max, Madre Natura, Kaita® y un extracto metanólico de propóleo de Oxapampa, el cual se elaboró en el laboratorio de Bioquímica de la UPC, como control (+) la clorhexidina al 0.12%. Para este estudio se utilizó 10 pocillos por cada extracto de propóleo, para el Streptococcus mutans y para el Streptococcus sanguinis individualmente. Se desarrolló con la técnica “Agar overlay interference test”, para lo cual se utilizó 200ml de Agar BHI homogenizado con las bacterias de manera independiente (un frasco por bacteria). Se distribuyó este agar en las placas, una vez solidificado se realizaron los pocillos con 150μL de los distintos tipos de propóleo y para el grupo control, se utilizó clorhexidina al 0.12%. Terminado este proceso se colocó en la cámara de anaerobiosis a 37°C, durante 72 horas. Por último, se realizó la medición del halo inhibitorio con una regla Vernier. Resultados: El extracto metanólico de propóleo de Oxapampa presentó halos de inhibición de mayor tamaño con una media de 33.15 + 3.26 mm frente a las cepas de Streptococcus mutans (ATCC 25175), para el Streptococcus sanguinis (ATCC 10556) su media fue de 23.23 + 0.82 mm. En el caso de los 4 extractos de propóleo comerciales, sólo 3 de ellos (Tintura de propóleo Farmagel, Madre Natura y Kaita®), tuvieron actividad antibacteriana frente a las cepas estudiadas, en todos los casos la actividad antibacteriana es menor que el control (+). Conclusiones: El extracto metanólico de propóleo de Oxapampa elaborado en el laboratorio tiene mayor actividad antibacteriana que los extractos comerciales frente a las cepas Streptococcus mutans (ATCC 25175) y Streptococcus sanguinis (ATCC 10556). De los 4 propóleos comerciales evaluados en el estudio, Tintura de propóleo Farmagel, Kaita®, Madre Natura y Tintura de propóleo Max, sólo tres de ellos tiene actividad antibacteriana frente a las cepas de Streptococcus mutans (ATCC 25175) y Streptococcus sanguinis (ATCC 10556). / The target was evaluate the “in vitro” antibacterial effect about five peruvian propolis on strains of Streptococcus mutans (ATCC 25175) and Streptococcus sanguinis (ATCC 10556), Having an experimental study design “in vitro” made in laboratorie of Microbiology of the Peruvian University of Applied Sciences.
