| description |
Equine infectious anemia (EIA) is a disease caused by a Lentivirus, and it represents a significant obstacle to the global equine industry. Its control relies on mandatory quarantine and euthanasia of seropositive horses. Active epidemiological surveillance is essential for effective EIA control. The objective of this study was to determine the seroprevalence of EIA in horses participating in cultural horseback riding events in the department of Meta, Colombia. A total of 92 blood samples were collected from horses participating in two events, held in the municipalities of Granada (n = 48) and Acacias (n = 44). Samples were analyzed using the agar gel immunodiffusion (AGID) test considered the gold standard and the enzyme-linked immunosorbent assay (ELISA). Diagnostic test results were analyzed using McNemar’s test and receiver operating characteristic (ROC) curves with JAMOVI statistical software. Seroprevalence detected by AGID was 6.5% (6/92), while ELISA indicated 16.3% (15/92), with higher seropositivity observed in Granada (8.8%) compared to Acacias (4.5%). The ELISA test, compared to AGID, had an area under the curve (AUC) of 0.620, sensitivity of 66.7%, and specificity of 87.2%. McNemar’s test showed a significant difference (p<0.05) between the two diagnostic methods. This study highlights that equines ><0.05) between the two diagnostic methods. This study highlights that equines testing positive for EIA should not participate in equestrian events outside their premises, in accordance with both national and international regulations. Furthermore, the findings suggest non-compliance with Colombian regulations by horse owners and event organizers, as only AGID-negative animals tested within the last six months should be allowed to participate. |

La anemia infecciosa equina (AIE) es una enfermedad causada por un Lentivirus, considerada un obstáculo para el desarrollo del sector equino mundial, que tiene como medida de control la cuarentena y eutanasia obligatoria de equinos seropositivos; siendo fundamental implementar estudios de epidemiología activa para el control de AIE. El objetivo de este estudio fue determinar la seroprevalencia de AIE en equinos de cabalgatas culturales en el Meta (Colombia). Para ello, se procesaron 92 muestras sanguíneas de equinos participantes en dos cabalgatas, distribuidos en los municipios de Granada (n = 48) y Acacias (n = 44), utilizando las pruebas de inmunodifusión en gel de agar (AGID) como gold standard, comparándola con la prueba enzimoinmunoanálisis de adsorción (ELISA). Los datos obtenidos de las pruebas diagnósticas fueron analizados con McNemar y curva ROC, a través del software estadístico JAMOVI. Se determinó una seroprevalencia de AIE por AGID de 6,5% (6/92) y ELISA de 16,3% (15/92), siendo mayor la seropositividad encontrada en el municipio de Granada (8,8%) en comparación con Acacias (4,5%). El área bajo la curva, la sensibilidad y especificidad de ELISA frente a AGID, fue de 0,620, 66,7% y 87,2%, respectivamente. Evidenciando diferencias significativas (McNemar, p <0,05) entre la capacidad diagnóstica de AGID en comparación con ELISA. Este estudio pone en evidencia a equinos seropositivos a AIE que no deberían participar de actividades ecuestres fuera de sus predios según normatividad nacional e internacional, además, que sus propietarios y los organizadores de estos eventos culturales no cumplen con la normatividad nacional en Colombia, referente a incluir solo equinos seronegativos de los últimos seis meses a AIE por la prueba AGID.> Universidad Nacional del Nordeste 2025-08-09 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://revistas.unne.edu.ar/index.php/vet/article/view/8234 10.30972/vet.3628234 Revista Veterinaria; Vol. 36 Núm. 2 (2025); 1-7 1669-6840 1668-4834 spa https://revistas.unne.edu.ar/index.php/vet/article/view/8234/8096 Derechos de autor 2025 Sonia Ximena Maldonado Soto , Paula Juliana Moreno Carrillo, Karla Sirene Alfonso Mojica, Juan Sebastian Banoy Melo, Natalia Pedraza Castillo, Dumar Alexander Jaramillo Hernández https://creativecommons.org/licenses/by-nc/4.0 |
