Effect of rearing density on nervous necrosis virus infection in Senegalese sole ( Solea senegalensis )

چکیده
Intensive fish farming at high densities results in a wide range of adverse consequences on welfare, including pathogen spreading, stress and increased mortality rates. In this work, we have assessed whether the survival Senegalese sole infected with nervous necrosis virus (NNV), responsible for severe disease outbreaks, is affected by rearing density. Based different ratios per surface area (g cm−2) water volume L−1), our research showed an earlier onset tanks containing NNV-infected reared medium density (MD: 0.071 g cm−2/5 L−1) (HD: 0.142 cm−2/10 as well higher cumulative values. However, transcription analysis hsp70, gr1 pepck genes, well-known biomarkers, seems to indicate that none challenged were under conditions. NNV load was slightly both dead sampled from MD HD groups, especially these where peaks seemed correlate increasing water. conclusion, suggest resulted values viral load.

Lectin-binding pattern of Senegalese sole Solea senegalensis (Kaup) testis.
The localization and characterization of oligosaccharide sequences in the testis of Senegalese sole Solea senegalensis was investigated using 12 lectins in combination with KOH saponification and sialidase digestion (K-s). The interstitial compartment contained all the sugar residues investigated, those bearing oligosaccharides terminating with sialic acid (Neu5Ac) alpha2,3Galbeta1,4GlcNAc, Neu...
متن کاملRole of the IFN I system against the VHSV infection in juvenile Senegalese sole (Solea senegalensis)
Senegalese sole is susceptible to marine VHSV isolates but is not affected by freshwater isolates, which may indicate differences regarding virus-host immune system interaction. IFN I induces an antiviral state in fish, stimulating the expression of genes encoding antiviral proteins (ISG). In this study, the stimulation of the Senegalese sole IFN I by VHSV infections has been evaluated by the r...

Characterization of stress coping style in Senegalese sole (Solea senegalensis) juveniles and breeders for aquaculture
The aim of this work was to characterize stress coping styles of Senegalese sole (Solea senegalensis) juveniles and breeders and to select an operational behavioural screening test (OBST) that can be used by the aquaculture industry to classify and select between behavioural phenotypes in order to improve production indicators. A total of 61 juveniles and 59 breeders were subjected to five indi...
متن کاملAntemortem versus postmortem methods for detection of betanodavirus in Senegalese sole (Solea senegalensis).
The suitability of nested reverse transcription polymerase chain reaction (nRT-PCR) to detect betanodavirus in blood samples from naturally infected Senegalese sole (Solea senegalensis) was evaluated in comparison with other diagnostic methods. Results indicated that histologic examination of brain lesions could be regarded as the most consistent indicator of nodavirus infection in this species...
