Abstract: In the fields of Medicine and bovine production, there is a wide variety of diseases affecting reproduction, in relation to the number of live births, the interval between births and open days, among others. Some of these diseases produce abortions and embryonic death, which explain the alteration of reproductive parameters. Many of these diseases have an infectious origin, such as parasites, bacteria, viruses and fungi, which are transmitted among animals. Besides, some of them have zoonotic features that generate problems to human health. Among these agents, the Neospora caninum, protozoan stands out. Its life cycle is fulfilled in several species of animals like the dog and the coyote. These two act as its definitive hosts and the cattle as its intermediary host. The Neospora caninum causes in the infected animals, reproductive disorders, clinical manifestations and decreased production which affects productivity of small, medium and large producers. Because of this, diagnostic techniques that allow understanding the epidemiological behavior of this disease have been developed. However in spite of being a major agent in the bovine reproductive health, few studies have been undertaken to determine the prevalence of this agent around the world. Therefore, the objective of this review was to collect updated information on the behavior of this parasite, targeting its epidemiology, its symptoms, its impact on production and the methods of its control and prevention. En medicina y producción bovina se presenta una gran variedad de enfermedades que afectan la reproducción, esto es, el número de nacidos vivos, el intervalo entre partos y los días abiertos, entre otros, ya que en algunas de estas enfermedades, ocurren abortos y muerte embrionaria, que explican la alteración de los parámetros reproductivos. Muchas de estas patologías son de origen infeccioso (parásitos, bacterias, virus y hongos), se transmiten de un animal a otro y algunas tienen carácter zoonótico, generando problemas en la salud humana. Dentro de dichos agentes se destaca la Neospora caninum, protozoario cuyo ciclo de vida se cumple en varias especies de animales como el perro y el coyote, que actúan como hospedadores definitivos y los bovinos, que constituyen el hospedador intermediario, produciéndoles alteraciones reproductivas, manifestaciones clínicas y disminución de la producción lo que repercute en productividad de peque os, medianos y grandes productores. Por lo anterior, se han desarrollado técnicas diagnósticas que permiten conocer el comportamiento epidemiológico de esta enfermed

Abstract: El uso de plantas medicinales hace parte tanto de la historia de la medicina en todas las culturas del mundo como de las costumbres populares, convirtiéndose en el punto de partida para el desarrollo de medicamentos tradicionales. En respuesta a los altos niveles de resistencia y a la presencia de residuos de plaguicidas en el ecosistema, se ha buscado en las plantas nuevas alternativas para el control de insectos. A partir del conocimiento popular de algunas plantas reconocidas por su acción insecticida, con esta investigación, se buscó determinar, experimentalmente, si Nicotiana tabacum, Brugmansia arborea, Sambucus nigra, Bidens pilosa y Ambrosia cumanenses tienen efecto contra los adultos de la mosca de los cuernos, Haematobia irritans, plaga de importancia que afecta el ganado vacuno. Utilizando el método de lixiviación en frío, se preparó el extracto de las hojas de cada una de las plantas. La evaluación del efecto insecticida, se realizó in Vitro, haciendo una aspersión topical de los extractos sobre las moscas. Todas las plantas mostraron efecto insecticida, aunque en diferentes grados de intensidad, siendo la más efectiva la Haematobia irritans. Con estos resultados, se sustenta el conocimiento popular y se resalta la necesidad de utilizar altas concentraciones del extracto para obtener efecto insecticida.

Abstract: Introducción: la actual preocupación por la resistencia del ganado a los medicamentos antiparasitarios y su residualidad en el ecosistema han llevado a la búsqueda de alternativas de control biológico de garrapatas, dentro de las cuales se encuentra el uso de plantas con efecto bioinsecticida. Objetivo: evaluar in vitro el efecto ixodicida de los extractos etanólicos de las hojas de Ambrosia cumanenses Kunth, Brugmasia arborea (L.) Larget, Bidens pilosa L., Sambucus nigra L. y Nicotiana tabacum L., obtenidos por Soxhlet sobre garrapatas adultas Boophilus microplus (acari: ixodidae). Métodos: los extractos de las plantas se obtuvieron por el método de extracción en caliente (Soxhlet). Para los ensayos se utilizaron garrapatas adultas, que fueron expuestas a cada uno de los extractos por medio de la prueba de inmersión de adultas. La estimación de la mortalidad se hizo a los 15 min y 24 h posexposición, teniendo en cuenta como mínimo efectivo 60 % de mortalidad. Inicialmente se usó el extracto puro y si presentaba eficacia se procedía a realizar diluciones hasta encontrar la concentración mínima eficaz. Resultados: el extracto de Nicotiana tabacum resultó ser un ixodicida eficiente hasta la dilución 2,5:10, con una mortalidad de 85 % en ambas mediciones; Ambrosia cumanenses mostró eficacia hasta la dilución 6,25:10 a las 24 h con una mortalidad de 80 %; Brugmasia arborea fue eficaz hasta la dilución 5,0:10 con 60 y 70 %, respectivamente, en cada medición; Bidens pilosa y Sambucus nigra no evidenciaron efecto ixodicida eficiente en este estudio. Conclusiones: el extracto de Nicotiana tabacum demostró ser el ixodicida más eficiente, inclusive a diluciones muy altas, como la de 2,5:10. Introduction: the current concern over the resistance of cattle to antiparasitic drugs and over their residues in the ecosystem have led to the search of tick biological control alternatives in which the use of plants with bioinsecticidal effects are included. Objective: to evaluate in vitro the acaricidal effect of ethanolic extracts of leaves from Ambrosia cumanensis Kunth, Brugmasia arborea (L.) Larget, Bidens pilosa L., Sambucus nigra L. and Nicotiana tabacum L., obtained through soxhlet, on adult ticks Boophilus microplus (acari: ixodidae). Methods: plant extracts were obtained by means of the hot extraction method (Soxhlet). Adult ticks were used for testing, which were exposed to each of the extracts in the adult immersion test. Mortality rate was estimated at 15 min and 24 h post-exposure, taking 60 % mortality as the minimum effective rate. At first, the pure extract
