Zinc accumulation in phosphate granules of Ucides cordatus hepatopancreas.
Amorphous phosphate granules are present in vertebrate and invertebrate organisms. The functions attributed to these structures depend on their mineral contents and organic matrix composition. In the present study we have determined zinc concentrations in the hepatopancreas of the crab Ucides cordatus from regions contaminated with zinc, and the elemental composition of hepatopancreal phosphate...
متن کاملCalcium Phosphate Granules in the Hepatopancreas of the Blue Crab Callinectes Sapidus
The hepatopancreas of the adult male blue crab Callinectes sapidus in intermolt was found to contain substantial amounts of calcium, magnesium, and inorganic phosphorus, averaging about 260, 20, and 250 microg-atoms per g wet tissue, respectively, accounting for over 10% of the tissue dry weight. Electron microscopy of the intact tissue showed three qualitatively different granular structures h...
متن کاملVibrio spp. and Salmonella spp., presence and susceptibility in crabs Ucides cordatus.
The presence of Vibrio spp. and Salmonella spp. in crabs marketed at the Bezerra de Menezes Ave., Fortaleza, State of Ceará, Brazil, was assessed between February and May, 2003. The number of individuals sampled in each one of the fifteen weekly samplings ranged between four and eight. Seven strains of Salmonella, from four different samplings, were identified, being five of them identified as ...
متن کاملElectron microscopy of glial cells of the central nervous system in the crab Ucides cordatus.
Invertebrate glial cells show a variety of morphologies depending on species and location. They have been classified according to relatively general morphological or functional criteria and also to their location. The present study was carried out to characterize the organization of glial cells and their processes in the zona fasciculata and in the protocerebral tract of the crab Ucides cordatu...
متن کاملBIOECOLOGY OF THE UÇÁ-CRAB, Ucides cordatus (LINNAEUS, 1763), IN VITÓRIA BAY, ESPÍRITO SANTO STATE, BRAZIL
The biology of the Ucides cordatus in Vitória Bay (ES) was evaluated as a possible tool for population management. Sampling occurred monthly for about a year (October 1998 to September 1999) with biometric analysis (CW = carapace width; WW = total wet weight) and abiotic factors on four transects, each with four bands (margin to supratidal region). The density was 3.7±1.5 crabs.m, with an incre...
