Histopatología diferencial de tres enfermedades bacterianas que afectan el hepatopáncreas de camarones peneidos.

Abstract

Differential histopathology of three bacterial diseases that affect the hepatopancreas of penaeid shrimp.

Necrosis aguda del hepatopáncreas: una revisión de la enfermedad en Penaeus vannamei

“…El impacto generado por las patologías bacterianas en la camaronicultura no es reciente, históricamente las infecciones causadas por bacterias, en especial por las especies pertenecientes al género Vibrio, han sido responsables de altas mortalidades (Martin et al, 2004;Morales-Covarrubias, 2004;Aguirre-Guzmán et al, 2005;Trujillo et al, 2005;Soto et al, 2010;Peña y Varela, 2013;Tinwongger et al, 2014;Varela y Peña, 2016). Algunas de las especies reportadas incluyen a V. parahaemolyticus, V. penaeicida, V. nigripulchritudo, V. alginolyticus, V. harveyi y V. campbelli (Morales-Covarrubias, 2004;Soto et al, 2010; Morales-Covarrubias y Gómez-Gil, 2014), con grados de afectación y virulencia variables.…”

Antibacterial effect of biosynthesized silver nanoparticles in Pacific white shrimp Litopenaeus vannamei (Boone) infected with necrotizing hepatopancreatitis bacterium (NHP B)

“…During the acute phase of the disease, the shrimp hepatopancreas is atrophied while during the chronic phase the hepatopancreas is melanized, the tubules are necrotized, among many other anomalies. This disease causes mortalities of up to 40%, and its diagnosis is based on the use of histological and molecular tools (Morales-Covarrubias, 2004;Avila-Villa et al, 2012;Nunan et al, 2013;Varela-Mejías & Peña-Navarro, 2016). Nanotechnology, the engineering of functional systems at the molecular scale, has been focused on the manufacturing industry, but it has also been applied in medicine as agents for in vitro detection, in vivo diagnostics, multimodal imagining, chemotherapy, phototherapy, and immunotherapy (Giasuddin et al, 2013;Lin, 2015).…”
