Shrimp production in Ecuador has increased; there are stocking densities as well. This has facilitated the increase of infectious diseases, like vibrioses which are pathogenic bacteria that can also be have as opportunistic ones. In order to control this disease antibiotic are used, though sometimes in improper manner, which leads to bacterial resistance. With this on mind, using natural substances instead of antibiotics is gaining adepts. Such natural substances like plant extracts are able to prevent bacterial growth, demonstrated by research done in both human and veterinary medicine. This preliminary research evaluated the effect of two medicinal plants: Lemon verbena (Aloysia triphilla) y Oregano (Origanum vulgare) on the presence of Vibrios sp on shrimp pond water. An infusion of these plants was made by placing 120 g of each plant in 120 ml of boiling water, and it was left for 1 hour until getting cool. Twenty one glass containers with a volume of 2000 ml were filled up with 1000 ml of pond water, and each plant extract at 6, 8 and 10 ml were added in triplicates. At 12, 24 y 48 h, 10 µl of each treatment was placed in a TCBS plate, and left incubated for 24 h. A two-way ANOVA was performed, which showed a significant interaction between the concentration of the plant extracts and the reaction/exposition time.The use of medicinal plants for the treatment of vibriosis could be suggested, provided a study of their interaction with aquatic organisms is performed. | En el Ecuador la producción del camarón ha incrementado, por ende han aumentado las densidades de cultivo, lo cual afecta al camarón provocando el incremento de enfermedades infecciosas, como la vibriosis que son bacterias patógenas o que pueden actuar como oportunistas; para controlar dicha enfermedad se utiliza antibióticos a veces de una manera inadecuada lo que genera resistencia bacteriana. De ahí surge la idea de sustituir los antibióticos por sustancias naturales como los extractos de plantas medicinales, que ayuden a impedir el crecimiento bacteriano, ya que existen hechos demostrados en investigaciones realizadas en medicina humana y veterinaria. Este trabajo es preliminar y evaluó el efecto de dos plantas medicinales Hierba luisa (Aloysia triphilla) y Orégano (Origanum vulgare) sobre la presencia de Vibrios sp. en agua de piscina camaronera, para lo cual se realizó una infusión de dichas plantas colocando 120 gramos de planta en 120 ml de agua hirviendo y se dejó enfriar por 1 hora; se utilizó 21 peceras con una capacidad de 2000 ml, en las cuales se adiciono 1000 ml de agua de la piscina y en cada una se añadió diferentes dosis del extracto (6, 8, 10 ml) cada una con tres repeticiones, y se analizó en diferentes horas (12, 24, 48); transcurrido el tiempo de actuación de los extractos se tomó 10 µl y se sembró en Agar TCBS, se dejó incubar por 24 horas para el conteo final de las unidades formadoras de colonias. Se realizó el ANOVA de dos vías el que indico que existe efecto de interacción significativo entre los factores de diferentes dosis de extractos de plantas medicinales y el tiempo de exposición.Finalmente, se puede sugerir el uso de plantas medicinales para el tratamiento de la vibriosis previo estudio de interacción con los organismos acuáticos.

In the following experimental work, the purpose will be to evaluate and analyze the blood samples of broiler chickens in order to observe the glucose ranges, thus being able to verify if they are in optimal conditions so that they do not suffer from hyperglycemia or hypoglycemia. To perform this analysis, the glucometer technique will be used in chickens that are under treatment with chamomile infusion in water. The samples already obtained from week 4 to week 7 showed that the glucose levels in the broiler chickens had a slight change in the part of lowering their levels, but their decrease is not simply due to the chamomile infusion that was administered but to the fact that the samples were taken in help which also contributed to the presentation of low glucose levels, this did not affect their development and growth but the results between weeks 4 and 5 were that the glucose levels were a little higher than 300 mg / dL, while from weeks 6 and 7 they were less than 300 mg / dL showing levels of 200 mg / dL. What this shows us is that when exposed to the administration of chamomile infusion in water and taking samples while fasting, the glucose levels shown had a decrease, although this did not show negative changes since the chickens reached their average weights in the corresponding weeks, but it is more recommended to take the glucose samples when they have already eaten to also know if they are stressed or if their food is well administered since that can also harm glucose levels. | In the following experimental work, the purpose will be to evaluate and analyze the blood samples of broiler chickens in order to observe the glucose ranges, thus being able to verify if they are in optimal conditions so that they do not suffer from hyperglycemia or hypoglycemia.

Para realizar este análisis se emplea la técnica del glucómetro en los pollos se que encuentren bajo el tratamiento de la infusión de la manzanilla en el agua. Las muestras ya obtenidas desde la semana 4 hasta la semana 7 mostraron que los niveles de glucosa en los pollos de engorde tuvieron un leve cambio en la parte de bajar sus niveles, pero su disminución no se debe simplemente a la infusión de manzanilla que se administró si no a que las muestras se las tomaba en ayuda lo cual también contribuye a que se presentaran niveles de glucosa bajos, esto no afecto a su desarrollo y crecimiento pero los resultados entres las semanas 4 y 5 fueron que los niveles de glucosa eran un poco mayor a 300 mg/dL, mientras que de las semanas 6 y 7 eran a menor a 300 mg/dL mostrando niveles de 200 mg/dL. Lo que esto nos demuestra que al estar expuesto a la administración la de infusión de la manzanilla en el agua y tomar las muestras en ayuno los niveles de glucosa mostrados tuvieron una disminución aunque esta no mostró cambios negativos ya que los pollos llegaron a su pesos promedios en las semanas correspondidas, pero más se recomienda tomar las muestras de glucosa cuando ya estos hayan comido para también saber si estos se encuentran estresados o si su alimentación está bien administrada ya que aquello también pueden perjudicar los niveles de glucosa.
