Intraperitoneal inocu<strong>la</strong>tion of the polysaccharidic fraction of P. cru<strong>en</strong>tum to<br />
sole specim<strong>en</strong>s did not induce an increase of the respiratory burst activity. On the<br />
contrary, the respiratory burst activity <strong>de</strong>creased in fish inocu<strong>la</strong>ted with polysacchari<strong>de</strong><br />
fraction or with bacterin within 24 h post-inocu<strong>la</strong>tion. This <strong>de</strong>crease in respiratory burst<br />
activity may be due to a immunosupression caused by stress after handling [39, 40] as it<br />
is not observed after 7 days of the inocu<strong>la</strong>tion.<br />
In short, the results obtained in vivo indicate that the polysaccharidic fraction<br />
from P. cru<strong>en</strong>tum does not <strong>en</strong>hance the respiratory burst activity compared to non<br />
inocu<strong>la</strong>ted fish.<br />
