Abstract
Se evaluó el efecto de la concentración del aceite esencial de Cymbopogon citratus_x000D_ sobre el crecimiento de Microsporum canis y Trichophyton rubrum in vitro. Para lo_x000D_ cual, se preparó Agar Sabouraud conteniendo concentraciones de dicho aceite_x000D_ esencial de 0.1, 0.5, 1, 1.5 y 2 μL/mL, respectivamente y además del control (0_x000D_ μL/mL). Sobre dicho medio se sembró por puntura central un fragmento de micelio_x000D_ de dichos hongos en estudio, provenientes de un cultivo monospórico, se incubó a_x000D_ 25 °C hasta 14 días. Se realizó tres repeticiones por triplicado por cada_x000D_ concentración incluyendo el control. La lectura del crecimiento micelial se realizó_x000D_ midiendo el diámetro de la colonia en milímetros a partir del séptimo día de siembra_x000D_ hasta el décimo cuarto día, se encontró que el aceite esencial de hierbaluisa a las_x000D_ concentraciones de 0.1, 0.5, 1, 1.5 y 2 μL/mL inhiben completamente el crecimiento_x000D_ de los hongos en estudio. Concluyéndose que el aceite esencial es un fuerte_x000D_ inhibidor del crecimiento de M. canis y T. rubrum.
Description
This thesis work had as purpose to evaluate the effect of essential oil of_x000D_ Cymbopogon citratus. “lemongrass” on the growth of Microsporum canis and_x000D_ Trichophyton rubrum in vitro. For which, I prepared Sabouraud Agar containing_x000D_ concentrations of the said essential oil, 0.1, 0.5, 1, 1.5, and 2 μL/mL, respectively,_x000D_ and in addition to the control (0 μL/mL). On this medium was inoculated by puncture_x000D_ central a fragment of mycelium of these fungi in the study, coming from a culture_x000D_ monosporic, was incubated at 25 °C up to 14 days. We performed three replicates_x000D_ in triplicate for each concentration including the control. The reading of mycelial_x000D_ growth was performed in millimeters the diameter from the seventh day of sowing_x000D_ until the fourteenth day, it was found that the essential oil of lemongrass from the_x000D_ concentration including the control._x000D_ The mycelial growth was measured by measuring the diameter of the colony in_x000D_ millimeters from the seventh day of sowing until the fourteenth day, it was found that_x000D_ the essential oil of lemon grass at the concentrations of 0.1, 0.5, 1, 1.5 and_x000D_ 2 μL / mL completely inhibit the growth of the fungi under study. Concluding that the_x000D_ essential oil is a strong growth inhibitor of M. canis and T. rubrum.
