Histology, ultrastructure and prevalence of Henneguya piaractus (Myxosporea) infecting the gills of Piaractus mesopotamicus (Characidae) cultivated in Brazil [PDF]
Diseases of Aquatic Organisms, 2005 The histopathological and ultrastructural characteristics of Henneguya piaractus, a parasite of the gill lamellae of Piaractus mesopotamicus, are reported here. Histological analysis showed that the plasmodia were of the intralamellar type. The development of the plasmodia resulted in marked dilatation of the infected lamellae, with the neighbouring ...E A, Adriano, S, Arana, N S, Cordeiroopenaire +2 more sourcesModulation of immunity and hepatic antioxidant defense by corticosteroids in pacu (Piaractus mesopotamicus)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2021 We investigated the impact of both the oral administration of hydrocortisone (HC) and an acute stressor on stress, innate immune responses and antioxidant system/oxidative stress responses of juvenile Piaractus mesopotamicus. Fish were either 1) given a commercial feed (C), 2) given a feed supplemented with 400 mg/kg HC, or 3) fed a commercial feed ...Neyrão, Iuri Moraes, Biller, Jaqueline Dalbello, Takahashi, Leonardo Susumu, Urbinati, Elisabeth Criscuolo +3 moreopenaire +4 more sourcesMolecular cloning and sequence analysis of growth hormone cDNA of Neotropical freshwater fish Pacu (Piaractus mesopotamicus)</a> </p><span class="r_subtitle"><img src="/img/openaccess.ico" alt="open access: yes" title="open access: yes" width="16" height="16"><i>Genetics and Molecular Biology</i>, 2008 </span><br><span class="r_content">RT-PCR was used for amplifying Piaractus mesopotamicus growth hormone (GH) cDNA obtained from mRNA extracted from pituitary cells.
