Two members of Aulopiformes (grinners) were examined for myxosporean parasites in their gallbladders. Synodus saurus and Aulopus filamentosus from Cretan Sea, Greece were infected by Ceratomyxa parasites which are described in this paper. Both species of Ceratomyxa are new and referred for the first time as Ceratomyxa cretensis n.sp. and Ceratomyxa(More)
A new myxosporean parasite, Zschokkella candia n. sp., from the gall-bladder of the wild parrotfish Sparisoma cretense (L.) (Perciformes: Scaridae) is described based on light and scanning electron microscopy. Mature spores are elliptical, with mean dimensions 11.2 ± 0.5 × 7.8 ± 0.1 μm and possess spherical polar capsules with mean diameter of 2.3 ± 0.3 μm.(More)
We announce the draft genome sequences of Vibrio alginolyticus strains V1 and V2, isolated from juvenile Sparus aurata and Dentex dentex, respectively, during outbreaks of vibriosis. The genome sequences are 5,257,950 bp with a G+C content of 44.5% for V. alginolyticus V1 and 5,068,299 bp with a G+C content of 44.8% for strain V2. These genomes provide(More)
Sequencing and annotation was performed for two large double stranded DNA bacteriophages, φGrn1 and φSt2 of the Myoviridae family, considered to be of great interest for phage therapy against Vibrios in aquaculture live feeds. In addition, phage-host metabolic interactions and exploitation was studied by transcript profiling of selected viral and host(More)
The controlling effect of single and multiple phages on the density of Flavobacterium psychrophilum at different initial multiplicity of infection (MOI) was assessed in batch cultures to explore the potential for phage-based treatment of this important fish pathogen. A high initial phage concentration (MOI = 0.3–4) was crucial for efficient viral lysis,(More)
Bacterial infections are a serious problem in aquaculture since they can result in massive mortalities in farmed fish and invertebrates. Vibriosis is one of the most common diseases in marine aquaculture hatcheries and its causative agents are bacteria of the genus Vibrio mostly entering larval rearing water through live feeds, such as Artemia and rotifers.(More)
Vibrio harveyi is an important marine pathogen that is responsible for vibriosis outbreaks in cultured fish and invertebrates worldwide. Here, we announce the draft genome sequences of V. harveyi strains VH2 and VH5, isolated from farmed juvenile Seriola dumerili during outbreaks of vibriosis in Crete, Greece.
