Evaluation of the Rickettsemia relationships of Anaplasma marginale with agroecological and productive factors in double purpose cattle in flooded savannas of Arauca, Colombia ; Valoración de las relaciones de Rickettsemia de Anaplasma marginale con factores agroecológicos y productivos en bovinos doble propósito en sabanas inundables del Arauca, Colombia

The aim of this study was to determine the relationship between the rickettsemia of A. marginale and environmental and genetic interactions in dual-purpose cattle in Arauca, Colombia. Blood samples were taken from 269 females from 14 farms, both in the dry and rainy seasons, and were analysed with the Wright and Hemacolor® techniques. The interaction between the presence of A. marginale with the variables breed type, season, age and parity was evaluated by analysis of variance. Resulted showed that 66.6% of positive animals to A. marginale were found in the dry season and 100% in the rainy sea... Mehr ...

The aim of this study was to determine the relationship between the rickettsemia of A. marginale and environmental and genetic interactions in dual-purpose cattle in Arauca, Colombia. Blood samples were taken from 269 females from 14 farms, both in the dry and rainy seasons, and were analysed with the Wright and Hemacolor® techniques. The interaction between the presence of A. marginale with the variables breed type, season, age and parity was evaluated by analysis of variance. Resulted showed that 66.6% of positive animals to A. marginale were found in the dry season and 100% in the rainy season (p<0.001), presenting rickettsemia values between 0 and 0.14% (average: 0.04%). The rickettsia A. marginale showed interaction with the breed type (p<0.05), the creole animals and crosses of Brown Swiss x zebu and Simmental x zebu being more resistant, whereas Bos taurus animals were more susceptible. Age, parity number, body condition and season were not dependent on rickettsemia. ; El objetivo del estudio fue determinar la relación existente entre la rickettsemia de A. marginale y las interacciones agroambientales y genéticas en bovinos de doble propósito en Arauca, Colombia. Se tomaron muestra de sangre a 269 hembras de 14 fincas, tanto en la época seca como de lluvias y fueron analizadas con las técnicas de Wright y Hemacolor®. Se evaluó la interacción entre la presencia de A. marginale con las variables grupo racial, época del año, edad y número de partos, mediante el análisis de varianza. Se encontró 66.6% de animales positivos en la época seca y 100% en la época lluviosa para A. marginale (p<0.001), presentando valores de rickettsemia entre 0 y 0.14% (promedio: 0.04%). La rickettsia A. marginale presentó interacción con el grupo racial (p<0.05), siendo más resistentes los animales criollos y cruces de Pardo Suizo x cebú y de Simmental x cebú y susceptibles los animales con predominio Bos taurus. La edad, numero de parto, condición corporal y época no fueron dependientes para la rickettsemia.
