Resumen
El presente trabajo de investigación se realizó con el fin de establecer la incidencia de Anaplasma bovis (Anaplasma marginal) en hatos bovinos de las asociaciones ganaderas del cantón Vinces provincia de Los Ríos-Ecuador, efectuado durante el período septiembre a Noviembre del presente año. Se visitaron 49 predios ganaderos distribuidos en las zonas de El Jobo, Pavana, Abras de Mantequilla, San Rafael y El Edén, donde se realizo el levantamiento de la información respectiva, y se recolectaron 350 muestras serológicas, las cuales se analizaron por medio de frotis directo y tinción de Giemsa; como método especifico para observar las ritketsias, dentro de los glóbulos rojos a través del microscopio con lente inmersión 100X.
El análisis realizados a los resultado, determino que la Incidencia de Anaplasma marginal en estos sectores fue del 39,14 %, con 137 animales positivos; además se estableció que las razas o cruces raciales más afectados fueron el ganado de genética lechera Bos taurus como Holstein x Brown swiss y Holstein friesian, con 37,23 %, y 32,85 % respectivamente; en cambio para los cruces raciales Brahman x Holstein y Brahman x mestizas, se obtuvieron incidencias bajas del 1,46 y 0 % en su orden.
En esta investigación se comprobó que existe una variabilidad de incidencia de Anaplasma bovis por hatos o sectores, debido a que las muestras no fueron homogéneas; pero existe una persistencia de esta infección en la mayoría de los hatos; lo que permite afirmar que es una enfermedad hematozoaria de importancia sanitaria y por ende económica para el productor ganadero de la zona de Vinces.
This research was conducted in order to establish the incidence of Anaplasma bovis (marginal Anaplasma) in cattle herds of livestock associations in the canton Vinces Los Rios province, Ecuador, conducted during the period September to November this year. 49 cattle farms distributed in the areas of El Jobo, Pavana, Abras Butter, San Rafael and El Eden, where the lifting of the respective information was held were visited and 350 serum samples were collected, which were analyzed by means of smear direct and Giemsa; as specific method to observe ritketsias within red blood cells through a microscope with 100X immersion lens. The analyzes the result determined that the incidence of marginal Anaplasma in these sectors was 39.14% with 137 positive animals; also established that breeds or crosses racial most affected were dairy cattle genetics as Bos taurus Holstein x Brown Swiss and Holstein Friesian, with 37.23% and 32.85% respectively; in exchange for Brahman x Holstein crosses racial and crossbred Brahman x, low incidences of 1.46 and 0% were obtained in their order. In this investigation it was found that there is variability of incidence of Anaplasma bovis by herds or sectors, because the samples were not homogeneous; but there is a persistence of this infection in most herds; allowing hematozoaria say that is a disease of public health importance and thus economic for the livestock producer in the area of Vinces.
