“…The detection of nodavirus in Tunisia occurred several years ago in farmed sea bass and sea bream [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In this study, the causative agent was detected from feral fish species for the first time.…”

“…At least five genogroups are recognized: red-spotted grouper nervous necrosis virus (RGNNV), striped jack nervous necrosis virus (SJNNV), barfin flounder nervous necrosis virus (BFNNV), tiger puffer nervous necrosis virus (TPNNV) and turbot nervous necrosis virus (TNNV) [7][8][9]. In the Mediterranean, Nodaviruses have been isolated from a number of wild and farmed fish species, including European sea bass Dicentrarchus labrax (L.), for which VNN is a major constraint in hatcheries [10][11][12][13][14]. In the Mediterranean, Nodaviruses from the RGNNV, SJNNV groups as well as reassortants have been detected [15][16][17].…”

This report describes the viral epidemiology of wild fish adjacent to cage farms within the Tunisian coasts and is focused on viral nervous necrosis virus (VNNV). A total of 92 apparently healthy wild marine fish were collected near aquaculture facilities in five different coastal areas of Tunisia. The brains and eyes of fish were examined by quantitative real time reverse transcriptase-polymerase chain reaction (qRT-PCR) to detect the nodavirus coat protein gene of. A total of 57 out of 92 (61.9%) samples were positive for nodavirus by qRT-PCR. This finding indicates that carrier fish occur at a considerable level in populations of wild marine fish. Samples from 13 fish species were found to be positive to the virus genome: Sarpa salpa, Trachurs trachurus, Boobs boops, Sardinella aurita, Diplodus vulgaris, Diplodus puntazzo Liza aurata, Diplodue sargus, Sparus aurata, Sardina pilchardus, Spicara maena, Spondyliosoma cantharus, and Diplodus annularis. The partial sequences of the RNA2 coat protein gene of these strains were identical with RGNNV type previously identified within farmed sea bass and sea bream species in Tunisia, with a homology >97%. With respect to the proximity of the sampling sites to the coast and to rearing facilities, results analysis can suggest that these viruses may be indigenous to Tunisian coastal waters.

“…Although Noda virus has been detected in various Mediterranean fish species (Iwamoto et al, 1999;Skiiris et al, 2001;Bovo et al, 1999), incidence of the disease has been reported only in cultured marine fish. Sea bass is the most commonly affected cultured Mediterranean marine species, although carriers have been found also in sea bream (Spams aurata L.) (Thiery et al, 1999α, Breuil et al, 2001, Castri et al, 2001.…”

Betanodaviruses cause viral nervous necrosis, an infectious neuropathological condition in fish that is characterized by necrosis of the central nervous system, including the brain and retina. This disease can cause mass mortality in larval and juvenile populations of several teleost species and is of global economic importance. The mechanism of brain and retina damage during betanodavirus infection is poorly understood. In this review, we will focus recent results that highlight betanodavirus infection-induced molecular death mechanisms in vitro . Betanodavirus can induce host cellular death and post-apoptotic necrosis in fish cells. Betanodavirus-induced necrotic cell death is also correlated with loss of mitochondrial membrane potential in fish cells, as this necrotic cell death is blocked by the mitochondrial membrane permeability transition pore inhibitor bongkrekic acid and the expression of the antiapoptotic Bcl-2 family member zfBcl-xL. Moreover, this mitochondria-mediated necrotic cell death may require a caspase-independent pathway. A possible cellular death pathway involving mitochondrial function and the modulator zfBcl-xs is discussed which may provide new insights into the necrotic pathogenesis of betanodavirus.
