Determinación de Rinotraqueítis Infecciona Bovina (BHV-1) en el municipio de Toca, Boyacá

Abstract

Introducción. La Rinotraqueítis Infecciosa Bovina (RIB) es una enfermedad infectocontagiosa que afecta principalmente a bovinos y bufalinos, encontrándose ampliamente distribuida a nivel mundial, siendo una de las principales causas de perdidas económica y físicas en las producciones. Objetivo. determinar la prevalencia de la Rinotraqueítis Infecciosa Bovina (BHV-1) en el municipio de Toca, Boyacá. Materiales y métodos. Se recolectaron 350 muestras de sangre Bovina, las cuales fueron procesadas en el laboratorio de la Universidad Pedagógica y Tecnológica de Colombia, mediante un kit comercial de ELISA. Resultados. La prevalencia para IBR, en el municipio de Toca, Boyacá, fue de 65,5%. No se encontró relación significativa con las variables estudiadas como abortos, distocias, no gestantes, repetición de celos, entre otras. Conclusión. La Rinotraqueítis Infecciosa Bovina es una de las principales causas de pérdidas económicas y físicas en las diversas producciones, sin embargo, no siempre es la principal causa de alteraciones reproductivas presentes en los bovinos.

Seroprevalence and risk factors associated with bovine herpesvirus 1 in dairy herds of Colombia

“…Holstein and Ayrshire had the highest seroprevalences among the evaluated breeds; this finding is similar to that reported by Ortíz-González et al [12]. However, Sibhat et al [25] have reported that the Jersey breed and crosses of Holstein-Friesian by Zebu have the highest seroprevalences of 62% and 41.8%, respectively.…”

“…In Sotaquirá, a significant statistical association was found with the presentation of abortions in herds, which is in agreement with the findings of Mahajan et al [37]. A statistical association between the presence of abortion and the disease was reported but differed from the observation made by Ochoa et al [11] and Ortíz-González et al [12], who did not report this relationship with abortion. In addition, gestation in virus-infected cattle can be carried to term with the birth of dead calves or calves that died shortly after birth or within the first 2 weeks [38].…”

“…However, Sibhat et al [25] have reported that the Jersey breed and crosses of Holstein-Friesian by Zebu have the highest seroprevalences of 62% and 41.8%, respectively. Holstein and Normande breeds were significantly associated (p ≤ 0.05) with the presence of antibodies against IBR; this finding is in contrast with the findings of Ortíz-González et al [12] and Sibhat et al [25]. Likewise, the Normande breed was 0.6277 (PR) less likely to have BHV-1 antibodies, and the Holstein breed was determined to be a risk factor for IBR infection.…”

“…Seroprevalence and risk factors associated with the presentation of antibodies against the virus that causes IBR were determined. The seroprevalence noted in the municipality of Sotaquirá was 57.5%, a percentage higher than those reported in Toca (65.5%) and Montería (Colombia; 74.7%) [12,17]. However, this was a low prevalence compared with that in Caquetá (90% [18] and 73.13% [19]) and Antioquia (85.51% [20].…”

“…Besides affecting the health and welfare of animals, it causes considerable losses to production caused by increased indirect costs associated with veterinary diagnosis, decreased dairy production, weight loss, and death [4]. In Boyacá, few investigations have been conducted regarding this disease [11,12].…”
