First report of Edwardsiellosis in cage-cultured sharpsnout sea bream, Diplodus puntazzo from the Mediterranean
BACKGROUND Edwardsiella tarda, is a serious bacterial pathogen affecting a broad range of aquaculture fish species. The bacterium has also been reported as a human pathogen, however recent studies have dissociated the fish pathogenic Edwardsiella from those isolated from humans by placing them in a new species, E. piscicida. Here we report the first case of Edwardsiellosis in cultured sharpsnou...
متن کاملAroclor 1254 inhibits the chemiluminescence response of peritoneal cavity cells from sharpsnout sea bream (Diplodus puntazzo).
Chronic exposure to polychlorinated biphenyls (PCBs) affect the immune system of fish and could lead to a decreased disease resistance. The effects of Aroclor 1254, PCB mixtures, on the Diplodus puntazzo innate immunity were examined by assaying the zymosan stimulated chemiluminescence response (CL) of peritoneal cavity cells (PCCs) at various times (1, 24, 48 h and 1-4 weeks) from intraperiton...
متن کاملComparative Ontogeny of the Digestive Tract in Sharpsnout Sea Bream Diplodus puntazzo Cetti and Common Pandora Pagellus erythrinus L
The ontogeny of the alimentary tract and its associated structures (liver, pancreas, gall bladder) was compared between sharpsnout sea bream Diplodus puntazzo and Pagellus erythrinus and some differences were highlighted. The first goblet cells appeared earlier in sharpsnout seabream (5-7 DAH) and later in common pandora (9-11 DAH), as well as taste buds which appeared at 11 DAH in sharpsnout s...
متن کاملDigestive Enzymes in Larvae and Juveniles of Farmed Sharpsnout Seabream (Diplodus puntazzo) (Cetti, 1777)
The ontogenetic development and pattern of main digestive enzyme activities (proteases, carbohydrases and lipases) were investigated in farmed sharpsnout seabream Diplodus puntazzo larvae and juveniles, during the passage from the larval stage to adult (from 21 to 277 days after hatching DAH). Larvae showed exponential growth, thus confirming that Rotifers and Artemia nauplii are suitable preys...
