Abstract (English): Introduction: Protists of the genus Labyrinthula cause the so-called “Wasting Disease” in seagrass, Thalassia testudinum. Monitoring in the Colombian Caribbean since 2008 has shown spatial and temporal variation in the disease’s incidence, but without the high mortality observed in other regions of the world. Objective: To analyze some epidemiological parameters in T. testudinum and to compare metabolites between healthy and infected plants. Methods: We recorded severity, incidence and prevalence of this disease in Tayrona National Natural Park and Providencia Island, and we analyze water and sediment samples. Additionally, we applied gas and liquid chromatography, coupled with mass spectrometry, to methanolic extracts from leaf and rhizome samples of healthy and infected shoots. Results: The meadows were in good condition, despite the scarce seagrass shoots in Tayrona and a high incidence (15 %) and severity (35.5 %) of the disease in Providencia. Infected plants had lower levels of phenols, flavonoids and sugars. Sulphated flavones with aglycone luteolin and diosmetin, sterols (sitosterol and stigmasterol) and volatile oxylipins are accumulated in leaves (3-hydroxy-2-isopentanone) and isopentaenoic and octadecatrienoic acids in rhizomes. Conclusions: These Colombian seagrasses have differential production of metabolites. Probably as a successful defense, even at low levels of severity (0.1 %) and incidence (1 %) of the disease.

Abstract (Spanish): Introducción: Los protistas del género Labyrinthula causan la denominada “Enfermedad del desgaste” en el pasto marino, Thalassia testudinum. Desde el 2008 los monitoreos en el Caribe colombiano han mostrado variación espacial y temporal en la incidencia de la enfermedad, pero sin la alta mortalidad observada en otras regiones del mundo. Objetivo: Analizar algunos parámetros epidemiológicos en T. testudinum y comparar metabolitos entre plantas sanas e infectadas. Métodos: Registramos la severidad, incidencia y prevalencia de esta enfermedad en el Parque Nacional Natural Tayrona e Isla de Providencia, y analizamos muestras de agua y sedimentos. Además, aplicamos cromatografía líquida y de gases, junto con espectrometría de masas, a extractos metanólicos de muestras de hojas y rizomas de brotes sanos e infectados. Resultados: Las praderas se encontraban en buen estado, a pesar de la escasez de brotes de fanerógamas marinas en Tayrona y una alta incidencia (15 %) y severidad (355 %) de la enfermedad en Providencia. Las plantas infectadas tenían niveles más bajos de fenoles, flavonoides y azúcares. Las flavonas sulfatadas con aglicona luteolina y diosmetina, los esteroles (sitosterol y estigmasterol) y las oxilipinas volátiles se acumularon en las hojas (3-hidroxi2-isopentanona) y los ácidos isopentanoico y octadecatrienoico en los rizomas. Conclusiones: Estos pastos marinos colombianos tienen producción diferencial de metabolitos. Probablemente como una defensa exitosa, aún a niveles bajos de severidad (0.1 %) e incidencia (1 %) de la enfermedad. [ABSTRACT FROM AUTHOR]
