RESUMEN

Introducción:

En la medicina militar, la aplicación de las sustancias antibacterianas en las infecciones tópicas, es importante en el tratamiento de las tropas.

Objetivos:

Evaluar el efecto antibacteriano sinérgico de rifamicina en propóleo sobre bacterias grampositivas.

Métodos:

Estudio experimental in vitro y comparativo. Se efectuó el análisis fitoquímico preliminar del propóleo de Apis mellífera. Se utilizaron 96 placas de agar Muller Hinton (Britania®) (48 placas para cada especie bacteriana) repartidas en 6 grupos (n = 8). grupo I (agua destilada), grupo II (alcohol etílico al 96 por ciento), grupo III (rifamicina al 0,5 por ciento), grupo IV (rifamicina al 1 por ciento), grupo V (propóleo al 20 por ciento) y grupo VI (rifamicina al 1 por ciento en propóleo al 40 por ciento); se empleó la metodología de Kirby - Bauer; las cepas usadas fueron Staphylococcus aureus ATCC 25923, Streptococcus pyogenes ATCC 19615 y las mediciones de las zonas de inhibición se efectuaron a las 24 horas.

Resultados:

Se detectaron compuestos fenólicos, taninos, flavonoides, alcaloides y triterpenoides en propóleo. Se comprobó el efecto antibacteriano del grupo V con 18,627 ± 0,1008 mm (92,59 por ciento) y 19,247 ± 0,0762 mm (96,74 por ciento), y el efecto antibacteriano sinérgico del grupo VI con 19,316 ± 0,1202 mm (96,02 por ciento) y 19,613 ± 0,0820 mm (98,58 por ciento), comparados con rifamicina al 1 por ciento (100 por ciento) sobre S. aureus ATCC 25923 y S. pyogenes ATCC 19615.

Conclusiones:

La combinación de rifamicina al 1 por ciento unida al propóleo al 40 por ciento presenta una mayor actividad antibacteriana in vitro sobre bacterias grampositivas debido a su efecto sinérgico(AU)
ABSTRACT

Introduction:

In military medicine, the application of antibacterial substances in topical infections are important in the treatment of troops.

Objectives:

To evaluate the synergistic antibacterial effect of rifamycin in propolis on gram-positive bacteria.

Methods:

In vitro and comparative experimental study. Preliminary phytochemical analysis of Apis mellifera propolis was carried out. 96 Muller Hinton agar plates (Britania®) (48 plates for each bacterial species) divided into 6 groups (n = 8) were used group I (distilled water), group II (96 percent ethyl alcohol), group III (rifamycin 0,5 percent), group IV (rifamycin 1 percent), group V (propolis 20 percent) and group VI (rifamycin 1 percent in 40 percent propolis); Kirby-Bauer methodology was used; the strains used were Staphylococcus aureus ATCC 25923, Streptococcus pyogenes ATCC 19615 and the measurements of the zones of inhibition were carried out at 24 hours.

Results:

Phenolic compounds, tannins, flavonoids, alkaloids and triterpenoids were detected in propolis. The antibacterial effect of group V was verified with 18,627 ± 0,1008 mm (92,59 percent) and 19,247 ± 0,0762 mm (96,74 percent), and the synergistic antibacterial effect of group VI with 19,316 ± 0,1202 mm (96,02 percent) and 19,613 ± 0,0820 mm (98,58 percent), compared with rifamycin 1 percent (100 percent) on S. aureus ATCC 25923 y S. pyogenes ATCC 19615.

Conclusions:

The combination of rifamycin 1 percent together with propolis 40 percent has a greater antibacterial activity in vitro on gram-positive bacteria due to its synergistic effect(AU)
