Diagnóstico de la ehrlichiosis monocítica canina: una revisión actualizada

Resumen

La ehrlichiosis monocítica canina (EMC) es causada por la infección de una rickettsia denominada Ehrlichia canis, este microorganismo se reproduce solamente en el citoplasma de los monocitos sanguíneos y macrófagos tisulares. La EMC ha sido reportada en todo el mundo, pero las frecuencias más altas se reportan en las regiones tropicales y subtropicales. La EMC no siempre es reconocida clínicamente, pues es difícil de diagnosticar debido a que los signos clínicos son variables, a que se presenta en diferentes fases y a la existencia de coinfecciones con otros patógenos transmitidos por garrapatas y otros agentes infecciosos. Las manifestaciones clínicas y las técnicas de diagnóstico tradicionales, como el diagnóstico hematológico y la demostración típica de mórulas de E. canis en el citoplasma de monocitos en frotis sanguíneos, se han utilizado para el diagnóstico de la EMC, sin embargo, las pruebas de diagnóstico por PCR y la serología mediante el uso de antígenos específicos son las pruebas más sensibles y específicas para el diagnóstico de la enfermedad. Este artículo presenta una revisión actualizada sobre el diagnóstico de la infección por E. canis en perros.
