Detección de una proteína asociada a la enfermedad de la necrosis hepatopancreatica aguda (AHPND) en Litopenaeus vannamei bajo cultivo semi-intensivo en Ecuador

Abstract: La presente investigación tuvo como objetivo detectar una proteína asociada a la necrosis hepatopancreática aguda (AHPND), en cultivos semi-intensivos en Ecuador. Se recolectaron camarones enfermos de tres camaroneras en la zona de Bellavista, provincia El Oro. Los hepatopáncreas fueron macerados y cultivados en medio TCBS y subcultivos en TSA y caldo LB. De las cepas bacterianas obtenidas, se extrajo las proteínas usando un kit comercial y se separaron mediante migración en gel SDS-PAGE. Estas fueron analizad… Show more

“…Viral and bacterial pandemics cause high morbidity and economic losses in shrimp farming [3]. The global incidence and impact of bacterial disease on the shrimp industry have been increasing since 2010 [4], primarily due to conditions in intensive shrimp culture systems [5]. One of the bacterial diseases responsible for the collapse of shrimp production is Early Mortality Syndrome (EMS).…”

“…Diseases originated by Vibrio are currently the ones that cause the greatest losses in shrimp farming (Mulyadi and Iba, 2020). In particular, acute hepatopancreatic necrosis disease (AHPND), which has strongly affected crops in Asia and North America, albeit not those in South America, is the disease that has caused the greatest economic losses in recent years (Saavedra-Olivos et al, 2018;Varela-Mejías and Alfaro-Mora, 2018;Aranguren et al, 2020).…”

“…Esta bacteria halofílica Gram-negativa pertenece a la familia Vibrionacea (Freitas, Glatter, & Ringgaard, 2019). Causante de grandes pérdidas de producción de camarón en China en el año 2009, propagándose a Vietnam (2010), Malasia (2011), Tailandia y Filipinas (2012) (Saavedra-Olivos et al, 2018), detectándose en el 2013 en Centroamérica y Suramérica (Mejías, 2018), asociada al síndrome de mortalidad temprana (EMS, por sus siglas en inglés), debido a la presencia de un plásmido que posee los genes PirA y PirB, que producen toxinas que causan la necrosis aguda en el hepatopáncreas (Restrepo et al, 2018), y consecuentemente la mortalidad del 100% del cultivo larval (Redrován, 2017).…”
