abstract = {A monitoring program to follow vibriosis incidents in the Greek marine aquaculture was implemented over the past 13 years. 273 isolates, from various cases originating from eight regions and nine hosts, were collected and characterized. The main aquaculture species of the survey were the European seabass (Dicentrarchus labrax) and the gilthead seabream (Sparus aurata). Various species of Vibrionaceae were associated with vibriosis. Vibrio harveyi had the highest prevalence and was isolated throughout the year from all hosts. During the warm months, Vibrio harveyi prevailed with frequent co-isolations of Photobacterium damselae subsp. damselae and Vibrio alginolyticus, while during spring, other Vibrio species were more abundant, such as Vibrio lentus, Vibrio cyclitrophicus, and Vibrio gigantis. Phylogenetic analysis using the mreB gene and the metabolic fingerprint of the isolates showed great variability within the species of the collection. The severity of the disease and the frequency of outbreaks make vibriosis (that is, mainly attributed to V. harveyi) an important concern for the regional aquaculture sector.},

abstract = {Aeromonas veronii is an emerging pathogen causing severe pathology and mortalities in European seabass aquaculture in the Aegean Sea, Mediterranean. More than 50 strains of the pathogen were characterized biochemically and genetically in order to study the epidemiology of the disease, as well as the phylogeny and virulence of the bacterium. Based on the phenotypic characteristics, the isolates form three groups consisting of: (a) the West Aegean Sea, non-motile, non-pigment-producing strains, (b) the West Aegean Sea, motile, and pigment-producing strains and (c) the East Aegean Sea motile strains that produce minute amounts of pigment. All strains were highly similar at the genomic level; however, the pattern of West/East geographic origin was reflected in biochemical properties, in general genomic level comparison and in the putative virulent factors studied. Type VI secretion system was not detected in the western strains. The outer membrane protein (OMP) profile which contains proteins that are putative antigenic factors, was very similar between strains from the different areas. Although most of the OMPs were detected in all strains with great sequence similarity, diversification according to geographic origin was evident in known antigenic factors such as the maltoporin LamB. A systematic comparative analysis of the strains is presented and discussed in view of the emergence of A. veronii as a significant pathogen for the Mediterranean aquaculture.},

abstract = {One of the most important bottlenecks of meagre (Argyrosomus regius) production is Systemic Granulomatosis (SG), a pathological condition affecting the majority of farmed populations. The aetiology of the disease, which is characterized by multiple granulomas in all soft tissues, is unknown; however, two hypotheses have been raised. The first is that it may be a metabolic disorder similar to systemic granulomas observed in other cultured fishes. The second hypothesis is that it is caused by bacterial pathogens, most likely Nocardia spp. (i.e. nocardiosis). The aim of this study was to test the bacterial pathogen hypothesis as the aetiological factor of SG. Meagre from various locations of Greece were sampled and examined using microbiological, molecular and histological techniques. The prevalence of granulomas in fish was 100% and was not correlated to an infectious agent, whereas nocardiosis was found in a single incidence (prevalence: 1.3%). The results suggest that nocardiosis is not the cause of SG, as it is most probably present in a confined geographical region in Greece. The metabolic disorder hypothesis for SG is more probable and more research has to been done to conclusively identify the aetiological factor of SG. © 2018 The Authors},

Commercial sized fish were affected by A. veronii bv. sobria and exhibited high morbidity and mortality. Gross pathologic features and histology revealed a systemic infection characterized by the presence of abscesses and chronic granulomatous inflammation. Two clinical bacterial isolates (Aero NS and Aero PDB) were identified as A. veronii bv. sobria based on bacteriological characteristics and sequence analysis for 16S rRNA and gyrB genes. Infectivity tests in the form of intraperitoneal injection administration (Aero NS) and immersion in a bacterial suspension (Aero NS and Aero PDB) revealed that both isolates could cause clinical signs similar to those observed in the field and high mortality rate. To our knowledge, this is the first report of A. veronii bv. sobria isolated from farmed European seabass in the Mediterranean Sea accompanied by supporting data of its pathogenicity. © 2017 The Japanese Society of Fish Pathology.},

abstract = {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 sharpsnout sea breams, Diplodus puntazzo in Greece. Case presentation: The disease has affected cultured sharpsnout sea breams of a commercial fish farm in a single location in East Greece. Two populations of sharpsnout sea breams stocked in two consecutive years in floating cages presented signs of disease which included nodules and abscesses in spleen and kidney, morbidity and cumulative mortality reaching 5.3 %. Using microbiological, biochemical and molecular tools we have identified Edwardsiella sp. as the main aetiological factor of the disease. Following phylogenetic analysis the bacterial isolates are grouped with the newly described Edwardsiella piscicida species. Conclusions: This is the first report of Edwardsiellosis in this species but most importantly in sea cage-cultured fish in the Mediterranean which may pose a serious threat for aquaculture fish species in this region. © 2015 Katharios et al.},
