Dinámica de la Leucosis Bovina en el ganado criollo Hartón del Valle en infección natural

Abstract: Carga proviral. Ganado criollo colombiano. Resistencia a enfermedades. resUMenLos bovinos criollos presentan características adaptativas de importancia. Se ha propuesto que el desarrollo y/o progresión de la leucosis bovina tiene bases genéticas. En el presente trabajo se estudió la dinámica del virus de la leucosis bovina en el ganado criollo Hartón del Valle en condiciones de infección natural. En 93 animales Hartón del Valle (HV), 30 Lucerna (LUC) y 30 Holstein (HOL) se evaluó la presencia del VLB por PCR-a… Show more

“…We established a statistically significant association between cattle age and seropositivity for BLV (p≤0.05). However, these results do concur with the findings reported by Hernandez et al [27], who were not able to observe such an association. In Sotaquirá, we found that the age range of 1-2 years is considered a protective factor against BLV infection, whereas ages <1 year and more than 4 years were risk factors for the disease.…”

“…These data disagree with the findings published by Betancur and Rodas [15] and Bautista et al [18], who found no significant association. In contrast, the results of this study agree with those of Hernandez et al [27], who also found a statistically significant association between breed and seropositivity using ELISA, showing that breed is a contributing factor for viral infection. Similarly, we determined that the Normando breed and cross-breeds were a preventive factor for BLV infection, whereas the Holstein breed was a risk factor for BLV infection.…”
