Differentiation of steroid-producing cells during ovarian differentiation in the protogynous Malabar grouper, Epinephelus malabaricus.
To understand the mechanism of sex differentiation in the protogynous Malabar grouper Epinephelus malabaricus, we performed an immunohistochemical investigation of the expression of three steroidogenic enzymes, cholesterol-side-chain-cleavage enzyme (CYP11a), aromatase (CYP19a1a), and cytochrome P45011beta-hydroxylase (CYP11b), in the gonads during ovarian differentiation. Strong positive immun...
متن کاملProsorhynchus maternus sp. n. (Digenea: Bucephalidae) from the Malabar grouper Epinephelus malabaricus (Perciformes: Serranidae) off New Caledonia.
A new species, Prosorhynchus maternus sp. n., is described from the serranid fish Epinephelus malabaricus (Bloch et Schneider) in the waters off New Caledonia. It belongs to a group of Prosorhynchus species from serranids in which the uterus is restricted to the postovarian region. Its distinguishing features include the vitellarium relatively distant from the rhynchus, the cirrus-sac relativel...
متن کاملHistopathological changes caused by Enteromyxum leei infection in farmed sea bream Sparus aurata.
Histological examinations were carried out on the stomach, pyloric caeca and 4 different parts of the intestine, as well as the rectum, hepatopancreas, gall bladder and spleen of 52 sea bream Sparus aurata spontaneously infected by Enteromyxum leei. Fifteen fish from a non-infected farm were included as a control. Clinical signs appeared only in extensively and severely infected fish. We observ...
متن کاملMolecular profiling of the gilthead sea bream (Sparus aurata L.) response to chronic exposure to the myxosporean parasite Enteromyxum leei.
The aim of the present work was to investigate the transcriptome response of gilthead sea bream (Sparus aurata) after challenge with the myxosporean Enteromyxum leei, a wide-spread enteric parasite causing heavy economic losses in Mediterranean sparid farms. This parasite causes severe desquamative enteritis which usually leads to death of the fish, and there are no preventative or curative tre...
