Studies of parasites that infect the nervous system of Amazonian fish: why are these studies neglected?

Lincoln Lima Corr

It is noticed that parasites that infect the Nervous System in Amazonian fish, manifest an action that directly interferes with peripheral vision loss and indirectly are manipulative and alter the behavior of these hosts, thus facilitating being predated so that the parasitic cycle ends in the bird, somehow preserving the maintenance and the parasite/host relationship in the environment. It is observed that this parasitic mechanism is little studied in the Amazon region, even though it is the region with the greatest diversity of freshwater fish, such infections were observed in only nine species of fish. We recently found new species of fish that live in the central Amazon region that were infected with the parasite Austrodiplostomum sp. Studies of parasites of fish from natural environments such as Austrodiplostomum sp. they are considered as “Neglected Parasite Group”, besides being an intriguing, complex and mysterious transmission system, it is a very incipient study, when compared with other environmental parasites.
