Rubrivivax gelatinosus biomass as an immunostimulant for pacu Piaractus mesopotamicus
(Wiley-Blackwell, 2017-09-01)
Rubrivivax gelatinosus is a bacterium present in the environment successfully used for treatment of fish industry effluent. Besides cleaning the effluent, this bacterium provides a biomass rich in proteins and carotenoid ...
Atividade respiratória de leucócitos como indicador de imunidade inata de pacu (Piaractus mesopotamicus)
(2013-05-01)
The present study evaluated the assay to quantify the respiratory burst activity of blood leukocytes of pacu as an indicator of the innate immune system, using the reduction of nitroblue tetrazolium (NBT) to formazan as a ...

Thalassophryne nattereri fish venom: from the envenoming to the understanding of the immune system
(BioMed Central, 2014)
Abstract
Thalassophryne nattereri (niquim) is a venomous fish found off North and Northeast coast of Brazil, where it is known by the severity of the accidents involving humans. This review ...
β-Glucan enhances respiratory activity of leukocytes suppressed by stress and modulates blood glucose levels in pacu (Piaractus mesopotamicus)
(2020-04-01)
We evaluated the immune response of pacu fed with a β-glucan diet (0.5%) for 10 days. After the feeding period, fish were subjected to handling and 3 h after, inoculated with Aeromonas hydrophila. Fish were sampled before ...
Proposed method for agglutinating antibody titer analysis and its use as indicator of acquired immunity in pacu, Piaractus mesopotamicus
(Instituto Internacional de Ecologia, 2014-02-01)
Antibody can be assessed by agglutinating antibody titer which is a quantitative measure of circulating antibodies in serum from fish previously immunized. The antibody evaluation has been performed with different fish ...
Energy deficit does not affect immune responses of experimentally infected pacu (Piaractus mesopotamicus)
(Elsevier B.V., 2015-04-01)
We investigated if the energy deficit following a 30-day starvation period could affect the ability of fish to mount immune responses after experimental exposure to Aeromonas hydrophila. Fish were submitted to two feeding ...
