Background: The olive tree (Olea europaea L.), the most widespread plant species in the Mediterranean basin, includes two forms: cultivated (var Europaea) and wild (var Sylvestris). Wild olive trees or oleasters cover large areas in Algeria. It has been shown that oil from oleaster has a higher content of phenolic compounds, which could have antimicrobial properties. Objective:: The objective of this study was to assess the antibacterial activity of phenolic extracts from four Algerian oleaster oils and an extra virgin olive oil (EVOO) from Chemlal variety. Methods: Phenolic compounds were determined by UHPLC-MS. Antibacterial activity was tested against six referenced human enteropathogenic bacteria by the agar disc diffusion method by measuring the diameters of the zone of inhibition. Results: The results revealed a similarity between the phenolic composition of oleasters 1 and 3 and between oleaster 4 and EVOO; however, the phenolic composition of oleaster 2 that the poorer was markedly different with a higher content of free phenolic alcohols and lower in secoiridoids.

Los Grupos

Objetivo: Comparar la prevalencia de cuatro bacterias periodontopáticas incluyendo Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum y Treponema denticola en muestras de placa supragingival de niños con y sin anemia de Fanconi. Material y métodos: Muestras de placa supragingival fueron colectadas en 71 personas con edades entre 6-18 años de edad. Las muestras se dividieron en tres grupos: anemia de Fanconi pre-trasplante (n= 25), anemia de Fanconi post-trasplante (n=23) y control (n=24). Las bacterias se identifi on mediante la reacción en cadena de la polimerasa para amplifi in vitro al gen codifi 16S rRNA. Resultados: El A. actinomycetemcomytans sólo fue encontrado en una muestra del grupo pretrasplante. El microorganismo P. gingivalis se identificó en una muestra del grupo pre-trasplante y en una del grupo post-trasplante. El T. denticola se encontró únicamente en dos muestras del grupo pre-trasplante. El microorganismo F. nucleatum se observó en todos los grupos. La presencia de los microorganismos varió del 30% en el grupo control al 58% en el grupo Prétrasplante. No fueron encontradas diferencias estadísticas entre los grupos. Conclusión: Los resultados del estudio sugieren que las alteraciones sistémicas encontradas en los individuos con AF no afectan la prevalencia de las cuatro bacterias analizadas.

Fusobacterium nucleatum has been employed for the first time to synthesize fluorescent carbon dots which could be applied for the determination of Fe3+ ions in living cells and bioimaging in vitro and in vivo with excellent biocompatibility.
