ABSTRACT
Background and Aim: Infectious bovine rhinotracheitis (IBR) is an infectious disease widely distributed globally and is considered the main cause of various reproductive and respiratory tract diseases in cattle and buffaloes. This study aimed to estimate seroprevalence and determine risk factors associated with the presentation of IBR in the municipality of Sotaquirá, Boyacá (Colombia). Materials and Methods: A descriptive cross-sectional study with simple random sampling was performed, and the sample size was 1,000 cattle. Blood samples were obtained by coccygeal venipuncture and processed through indirect enzyme-linked immunosorbent assay using the Synbiotics® kit (Zoetis, New Jersey, USA) with a sensitivity and specificity of 96% and 98%, respectively. Data were processed using the statistical program EpiInfo® (Centers for Disease Control and Prevention; Atlanta, Georgia). Results: A high seroprevalence of 57.5% was established. Seroprevalence was the highest in cattle >4 years of age (65.0% apparent seroprevalence [AS]; 67% true seroprevalence [TS]) and in the Holstein breed (65.5% AS; 67.8% TS). The breed and age of the animals were significantly associated with each other. The Holstein breed, age group >4 years, uncertified semen, and fetal death were established as risk factors for IBR. In comparison, the age groups of <1 and 1-2 years and the Normande breed were established as protective factors against the bovine herpesvirus-1 virus. Conclusion: Management factors, such as livestock from other owners and animal purchases, which affect disease presentation, are evident. The implementation and development of novel prevention and control measures for IBR at the national level are necessary.
ABSTRACT
Resumen Introduction 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.
Abstract Introduction Infectious Bovine Rhinotracheitis (IBR) is an Infectious contagious disease that mainly affects cattle and bufalin, being widely distributed worldwide, being one of the main causes of economic and physical losses in production. Objective. Determine the prevalence of Infectious Bovine Rhinotracheitis (BHV-1) in the municipality of Toca, Boyacá. Materials and methods. 350 Bovine blood samples were collected, which were processed in the laboratory of Universidad Pedagógica y Tecnológica de Colombia, through a commercial kit of ELISA. Results. The prevalence for IBR, in the municipality of Toca, Boyacá, was 65.5%. No significant relationship was found with the variables studied such as abortions, dystocias, non-pregnant cattle, repetition of estrus, among others. Conclusion. Infectious Bovine Rhinotracheitis is one of the main causes of economic losses in the various productions, however, it is not always the main cause of reproductive alterations present in Bovines.
Resumo Introdução A Rinotraqueíte Infecciosa Bovina (RIB) é uma doença infectocontagiosa que afeta principalmente os bovinos e bufalinos, estando amplamente distribuída a nível mundial, sendo uma das principais causas de perda económica e física nas produções. Objetivo. Determinar a prevalência da Rinotraqueíte Infecciosa Bovina (BHV-1) no município de Toca, Boyacá. Materiais e métodos. Recolheram-se 350 amostras de sangue de bovinos, que foram processadas no laboratório da Universidad Pedagógica y Tecnológica de Colombia, pelo kit comercial de ELISA. Resultados. A prevalência de IBR, no município de Toca, Boyacá, foi de 65,5 %. Não se encontrou relação significativa com as variáveis estudadas como abortos, distocias, não gestantes, repetição de cios, entre outras. Conclusão. A Rinotraqueíte Infecciosa Bovina é uma das principais causas de perda económica e física nas diversas produções, no entanto, não sempre é a principal causa de alterações reprodutivas presentes nos bovinos.
