High seroprevalence of equine infectious anemia in workhorses from an endemic region in Northeast Argentina
La anemia infecciosa equina (AIE), también conocida como fiebre del pantano,es una enfermedad infecciosa causada por un virus ARN común en équidos,burros y mulas. Tiene una distribución mundial. El objetivo de este estudio fueinvestigar la prevalencia y la incidencia serológica de AIE en 118 caballos dela provincia de Corrientes, zona endémica del Nordeste Argentino, durante unperiodo de tres años (2014-2016). Se realizaron tres muestreos de un total de118 caballos de trabajo. Se obtuvieron muestras de sangre completa de cadacaballo y re-muestreos posteriores por punción yugular con agujas estériles,guantes y jeringas desechables. La prevalencia de AIE fue de 77,2% en 2014,81,3% en 2015 y 88,7% en 2016. La incidencia acumulada de la enfermedadfue de 0,30 en un año y de 0,35 en dos años. Considerando que la AIE es undesafÃo importante para los sistemas de producción de equinos en laArgentina, el éxito del control de la enfermedad requerirá el esfuerzo conjuntode autoridades sanitarias, veterinarios y propietarios de caballos.Equine infectious anemia (EIA), also known as swamp fever, is an infectious disease caused by an RNA virus common in equids, donkeys and mules. It has a worldwide distribution and is currently considered a global disease. The aim of this study was to investigate the serological incidence and prevalence of EIA in 118 horses from the province of Corrientes, an endemic area of Northeast Argentina, over three years (2014-2016). Three samplings of a total of 118 workhorses were performed. Whole blood samples of each horse and subsequent resamplings were obtained by jugular puncture with sterile needles, gloves and disposable syringes. EIA prevalence was 77.2% in 2014, 81.3% in 2015 and 88.7% in 2016. The accumulated incidence of the disease was 0.30 in one year and 0.35 in two years. Considering that EIA is a major challenge for equine production systems in Argentina, successful disease control will require the joint effort of sanitary authorities, veterinary practitioners and horse owners.Fil: Espasandin, Ana Gabriela.

Comparison of serological techniques for the diagnosis of equine infectious Anemia in an endemic area of Argentina
Equine Infectious Anemia is a transmissible viral disease present worldwide, caused by an RNA virus. Viral transmission is mainly mechanical through blood or its products most frequently by blood-sucking arthropods and iatrogenesis as well. OIE recommends Coggins Test as the diagnostic method of choice. Some ELISA tests detect antibodies earlier than the Coggins test, but may produce false-positive results. Currently, new techniques for EIA diagnosis are being developed, such as fluorescence polarization assay which is a simple method for measuring antigen-antibody interaction. The aim of this study was to assess cELISA and Fluorescence Polarization Assay performance for the serological diagnosis of EIA by comparing their results with those of the Coggins test. Tests were performed on 91 workhorses from an endemic zone in the northeast region of Argentina. From the total samples analyzed, 42 tested negative and 49 tested positive in the Coggins test. Same results were obtained using FPA. Using the cELISA, 41 negative results and 50 positive results were obtained. The Receiver Operating Characteristic analysis showed that FPA performance was excellent. Therefore FPA is proposed as an outstanding EIA diagnostic test to be validated in the near future by its simplicity, speed, and objective interpretation of results.Fil: Espasandin, Ana Gabriela.
