“…Histopathological analysis of the hepatopancreatic tissues in L. vannamei provides information on morphological changes, tissue lesions, their severity, and cellular responses to the presence of VpN and VpP strains [27, 40, 67, 68]. In the present study, the control group (Ctrl) exhibited uniform structures of the hepatopancreatic tubules with healthy digestive cells E, F, R, and B, as previously reported [69-71].…”

The shrimp industry has historically been affected by viral and bacterial diseases. One of the most recent emerging diseases is the Acute Hepatopancreatic Necrosis Disease (AHPND), which causes severe mortality. Despite its significance to both sanitation and economics, little is known about the molecular response of shrimp to this disease. Here, we present the cellular and transcriptomic responses ofLitopenaeus vannameiexposed to twoVibrio parahaemolyticusstrains for 98h, wherein one is non-pathogenic (VpN) and the other causes AHPND (VpP). Exposure to VpN strain resulted in minor alterations in hepatopancreas morphology, including reductions in the size of R and B cells as well as detachments of small epithelial cells from 72 h onwards. On the other hand, exposure to VpP strain is characterized by acute detachment of epithelial cell from the hepatopancreatic tubules and infiltration of hemocytes in the inter-tubular spaces. At the end of exposure, RNA-Seq analysis revealed functional enrichment in biological processes, such as thetoll3receptor signaling pathway, apoptotic processes, and production of molecular mediators involved in the inflammatory response of shrimp exposed to VpN treatment. The biological processes identified in the VpP treatment include superoxide anion metabolism, innate immune response, antimicrobial humoral response, andtoll3receptor signaling pathway. Furthermore, KEGG enrichment analysis revealed metabolic pathways associated with survival, cell adhesion, and reactive oxygen species, among others, for shrimp that were exposed to VpP. Our study proves the differential immune responses to two strains ofV. parahaemolyticus,one pathogenic and the other nonpathogenic, enlarges our knowledge on the evolution of AHPND inL. vannamei, and uncovers unique perspectives on establishing genomic resources that may function as a groundwork for detecting probable molecular markers linked to the immune system in shrimp.

“…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.…”

Las diferencias entre el sistema cardiovascular de los crustáceos decápodos, enfatizando en los Penaeidos, con respecto a los vertebrados y sus implicaciones, han generado un creciente interés en su estudio y comprensión, dada sus actividades inmunoefectoras y fisiológicas. Se presenta el proceso global del recorrido hemolinfático, acompañado de descripciones histológicas de los diferentes órganos, así como los detalles de sus estructuras en especímenes juveniles y adultos de Penaeus vannamei sanos, en secciones histológicas de tejidos procesados mediante técnicas de rutina. Se incluye la descripción del corazón, arterias, órgano linfoide, branquias, lagunas y senos hemales. También, se incluye una reseña, no exhaustiva, sobre los mecanismos de funcionamiento y control asociados, sustentados por información bibliográfica sobre estudios realizados bajo condiciones normales de salud de los camarones examinados. Se incluye valores promedio de ritmo cardíaco a través de los diferentes estadíos de desarrollo, así como valores de volúmenes y presiones arteriales.
