Abstract Viral nervous necrosis (VNN) certainly represents the biggest challenge for sustainability and development of aquaculture. A large number economically relevant fish species have proven to be susceptible disease. Conversely, gilthead sea bream has generally been considered resistant VNN, although it possible isolate virus from apparently healthy sporadically affected larvae postlarvae. Unexpectedly, in 2014–2016 an increasing hatcheries Europe experienced mass mortalities larvae. Two...
Following the Mass Mortality Events (MMEs) of pen shell P. nobilis in Campania region and Sicily, a survey moribund specimens was also conducted other Italian regions (Campania, Tuscany, Sardinia Apulia) Spain (Catalunya). Histopathological molecular examination 27 nobils revealed different types pathogens associated with tissue lesions, morbidity mortality. Presence Mycobacterium, Vibrio species, Haplosporidium pinnae Perkinsus sp. were detected, differently distributed into areas. The...
Abstract Sturgeon species are well-suited for aquaculture because of their favourable characteristics, including robustness, suitability farming in facilities unsuitable other fish species, and adaptability to diverse conditions. The Russian sturgeon ( Acipenser gueldenstaedtii , Brandt Ratzeburg 1833) is one the most prominent farmed species; however, like it susceptible significant losses from bacterial viral diseases. Beyond infectious causes, there few reports documenting conditions that...
ABSTRACT The Coxiellaceae bacterial family, within the order Legionellales, is defined by a collection of poorly characterized obligate intracellular bacteria. zoonotic pathogen and causative agent human Q fever, Coxiella burnetii , represents best-characterized member this family. establish replicative niches diverse host cells rely on their for survival, making them challenging to isolate cultivate laboratory setting. Here, we describe new genus family that has been previously shown infect...
Intracellular microcolonies of bacteria, in some cases developing large extracellular cysts, have been historically reported infecting a wide diversity economically important mollusc species worldwide, sometimes associated with severe lesions and mass mortality events. As an effort to characterise those organisms, traditionally named as Rickettsia or Chlamydia -like organisms (RLO/CLO), via international collaboration, 98 samples comprising 20 were collected over 10 countries examined using...
This work aims to generate the data needed set epidemiological cut-off values for minimum inhibitory concentration (MIC) and disc-diffusion zone measurements of Vibrio anguillarum. A total 261 unique isolates were tested, applying standard methods specifying incubation at 28°C 24-28 h. Aggregated MIC distributions a 247 determined in 9 laboratories 11 agents. Data aggregations disc 10 agents analysed contained between 157 218 observations made by 4 7 laboratories. Acceptable ranges quality...
In order to establish the meaning of data generated in antimicrobial agent susceptibility tests, it is necessary develop internationally harmonised interpretive criteria. Currently, such criteria have not been developed for studies fish pathogen Yersinia ruckeri. This work that would be required set epidemiological cut-off values this species had using a standardised disc diffusion method specified use Mueller Hinton agar and incubation at 22°C 24-28 h. Using method, sets inhibition zones 4...
Despite the negative impact of viral hemorrhagic septicemia (VHS) and infectious hematopoietic necrosis (IHN) on European rainbow trout farming, no vaccines are commercially available in Europe. DNA protective under experimental conditions, but testing intensive farming conditions remains uninvestigated. Two encoding glycoproteins (G) recent Italian VHSV IHNV isolates were developed tested for potency safety conditions. Subsequently, a field vaccination trial was initiated at disease-free...
Gilthead sea bream (GSB) (Sparus aurata) have been generally considered to be resistant viral encephalo-retinopathy. However, the recent increase of number outbreaks in hatcheries caused by nervous necrosis virus (NNV) called RGNNV/SJNNV, a reassortant virus, has encouraged researchers investigate disease pathogenesis this species, with particular emphasis on fish age. For purpose, experimental challenges juveniles and larvae were carried out. Four trials performed infecting GSB different...
Biological invasions pose a serious threat to local flora and fauna have negative impacts on ecosystems. Invasive parasites can also cause severe losses in aquaculture. In this article, we provide evidence of the recent spillover an African parasite with complex, three-host life cycle that has rapidly successfully established itself Middle East, most likely due migration its final hosts (great cormorant) from Africa. This case introduction into country intensive aquaculture is important...
Abstract Mortality in wild fish populations represents a challenging issue for public health inspectors. When single species is involved, an infective aetiology frequently suspected, with focus on viral notifiable diseases. However, other agents not subjected to regulation and causing mortality common carp have been reported such as edema virus (CEV). In mid‐June 2020, severe was observed artificial lake north‐east of Italy. Sleepy were noted some days before the beginning itself, which...
In November 2020 a mortality episode (30%) in juvenile Siberian and Russian sturgeons (Acipenser baerii, Brandt, A. gueldenstaedtii, Brandt & Ratzeburg) GUBA hybrid (A. gueldenstaedtii × baerii) occurred hatchery Northern Italy, associated with severe coelomic distension abnormal reverse surface swimming. The fish were reared concrete tanks supplied by well water, fed at 0.4% of body weight (b.w.) per day. Thirty sturgeon specimens collected for necropsy, histological, bacteriological...
Viral nervous necrosis (viral encephalopathy and retinopathy) is caused by piscine nodavirus ( Nodaviridae, Betanodavirus). Since 1986, this highly infectious virus has mass mortalities of up to 100% in farmed saltwater freshwater fish around the world (with exception South America Antarctica), affecting >60 species across 10 orders. The Atlantic blue marlin Makaira nigricans Lacépède, 1802) a top-level predator found throughout tropical waters Indo-Pacific oceans. Despite their...
Cherax destructor is a crayfish endemic to south-eastern Australia and one of the last alien be introduced in Italy. In Laghi di Ninfa Natural Reserve (Latium region, Central Italy), species was probably 1999, but only reported for first time 2008. Nearby this area, most widespread red swamp Procambarus clarkii. Reserve, between 2008 2013 during spring summer, sampling carried out with baited traps assess distribution C. its possible relationship P. recorded 2008; few clarkii were detected...
This is the first description of a betanodavirus infection in dusky grouper Epinephelus marginatus within marine protected areas (MPAs) Balearic Islands. Histopathology techniques were employed to describe neurological lesions infected fish. Abnormal swimming, mortality, and detected all analysed individuals. Virus particles observed by means transmission electron microscopy. Reverse transcription RNA1 RNA2 followed cDNA amplification sequencing allowed viral classification. Phylogenetic...
