![]() ![]() The HPLC profile showed no traces of TTX but only the presence of paralytic shellfish poisons (saxitoxin - STX, gonyautoxin 2 - GTX 2, and gonyautoxin 3 - GTX 3). asellus were toxic when intraperitoneally administered into mice. This antibody was effective in detecting the presence of TTX in a total extract of Sphoeroides spengleri, which is one of the most toxic puffer fish found in the Atlantic Ocean Coast. asellus body extracts, indicating that TTX and its analogues are not the main toxic components of the extracts. The T20G10 monoclonal antibody raised against TTX and used as an indirect competitive enzyme immunoassay showed very low affinity for C. asellus specimens collected at Tocantins River in the town harbor of Cametá, Pará State, Brazil, and identified for the first time the components responsible for its toxicity as being different from tetrodotoxin (TTX), the well-known toxin isolated from puffer fish. We evaluated toxicity in extracts of twenty-four C. In addition, we used four different techniques mouse bioassay, ELISA, HPLC, and mass spectrometry. Melo from the National Center for Genetic Resources and Biotechnology Research, CENARGEN-EMBRAPA, Brasília, Brazil. Schwartz from the Biology Institute, University of Brasília, Unb, Brasília, Brazil and C. ![]() Oliveira from the Biosciences Institute, University of São Paulo, USP, São Paulo, Brazil S. The work has involved collaboration with J. ![]() asellus,atoxic puffer fish from the Amazonas State, Brazil. This year we are publishing a paper dealing with C. At this time we should ask, how do these fish from Amazon get to the shopping centers in Japan? Apart from the popular knowledge that it is poisonous, this species is poorly known by science, since there are not studies concerning its biology, behavior, ecology and toxicity.ĭuring a meeting of the International Society on Toxinology, which took place in Paris, France, we found out that this species has been sold in Japan by aquarists and the Japanese scientists started to perform studies using these commercial specimens bought in shopping centers at Ueno Station, Tokyo. Universidade de São Paulo, São Paulo, asellus (Müller and Troschel, 1848) is an Amazonian freshwater puffer fish which is occasionally sold by aquarists in Brazil. Eating habits: are we safe to consume freshwater puffer fish from the Amazon region in Brazil? ![]()
