添加標簽 | 總結: | The shrimp industry in Ecuador have increased in the last years to the point of becoming the second export product in Ecuador. The Shrimp´s exportation generated 3 million of dollars approximately in 2017. However, the appearance of diseases that attack shrimp has been an obstacle for the shrimp industry. The immune system of shrimp is different from that of human because they do not have an immune system of memory, this means that vaccines to treat the diseases do not work and antimicrobial drugs remain a significant safety concern. It is estimated that when a disease attacks the shrimp, only 60-70% will survive. Prebiotics extracted from natural sources such as beta glucans in the form of fibers emerges as a possible solution to strengthen the immune system of the shrimp, thus preventing it from getting sick and generating large demands for shrimp farms. We hypothesized that this fibers can stimulate the immune system to prevent shrimp diseases like vibriosis. In this project we will focus on extracting the fibers from vegetal sources in Ecuador and we will characterize those using common techniques as XRD, SEM, and then we will prove the effect of fibers as immunostimulants for shrimp through in vivo and in vitro assays. |
