Project description:Streptococcus agalactiae (Lancefield’s group B Streptococcus, GBS) is a major bacterial species of genus Streptococcus and has medical and veterinary importance by affecting mainly humans (Maione et al., 2005; Johri et al., 2006), cattle (Keefe, 1997) and fish (Mian et al., 2009). The GBS is the most important pathogen for the Nile tilapia, a global commodity of the aquaculture sector, causing outbreaks of septicemia and meningoencephalitis (Hernández et al., 2009; Mian et al., 2009).

The GBS is the most important pathogen for the Nile tilapia, a global commodity of the aquaculture sector, causing outbreaks of septicemia and meningoencephalitis (Hernández et al., 2009; Mian et al., 2009). This study aimed to evaluate the global abundancy of proteins among the main genotypes of GBS isolated from fish identified in Brazil using a label free shotgun liquid chromatography-ultra definition mass spectrometry (LC-UDMSE) approach and to compare the differential expression of proteins identified between isolates from fish and human.

Project description:Evolutionary alterations to cis-regulatory sequences are likely to cause adaptive phenotypic complexity, through orchestrating changes in cellular proliferation, identity and communication. For non-model organisms with adaptive key-innovations, patterns of regulatory evolution have been predominantly limited to targeted sequence-based analyses. Chromatin-immunoprecipitation with high-throughput sequencing (ChIP-seq) is a technology that has only been used in genetic model systems and is a powerful experimental tool to screen for active cis-regulatory elements. Here, we show that it can also be used in ecological model systems and permits genome-wide functional exploration of cis-regulatory elements. As a proof of concept, we use ChIP-seq technology in adult fin tissue of the cichlid fish Oreochromis niloticus to map active promoter elements, as indicated by occupancy of trimethylated Histone H3 Lysine 4 (H3K4me3). The fact that cichlids are one of the most phenotypically diverse and species-rich families of vertebrates could make them a perfect model system for the further in-depth analysis of the evolution of transcriptional regulation. examination of H3K4me3 in adult fin tissue of the Nile tilapia (Oreochromis niloticus)

Project description:Recirculation systems (RAS), which reduce water consumption and improve pathogen control are increasingly used in Atlantic salmon aquaculture. Performance and adaptation of fish to new farming environment is actively investigated. Here, responses to crowding stress were compared in salmon reared in two systems (RAS with brackish water and flowthrough with full salinity water) at low and high density.

Project description:Catfish farming remains number one among U.S. aquaculture production. Flavobacterium columnare, the causative agent of columnaris disease, produces substantial mortality during the production of freshwater farmed finfish species. F. columnare is ubiquitous in the aquatic environment, and outbreaks of disease are often triggered during the spring and summer months of the catfish production cycle. As food fish production continues to increase, the frequency of columnaris disease will only continue to rise within the aquaculture industry and thus new preventative measures will be required. Vaccination against different fish pathogens has proven to be an effective disease management practice within the aquaculture industry. To evaluate the immunological effect of bath immunization on catfish with a recombinant F. columnare DNAk protein vaccine, we performed RNA sequencing on skin samples from control and rDNAK immunized catfish at different time intervals. We evaluated the different gene expression patterns between the groups with a focus on identifying differences in innate and adaptive immune function.

Project description:GIFT is a type of freshwater farmed fish with high economic value and nutritional value. The liver is an important organ of fish metabolism. Once it is damaged or the disease occurs, it will lead to metabolic disorders and decreased disease resistance, and may cause other secondary diseases. In the high-density intensive culture of tilapia, the feed nutrition is not balanced, especially the addition of high-fat feed. High fat content can accelerate the growth of fish, but long-term feeding of high-fat diet can lead to metabolic disorders of fish, accumulation of fat in the body, easy to cause fatty liver, and ultimately death due to liver necrosis or hemorrhage, seriously affecting the breeding benefits. The main purpose of this study was to investigate the effects of apple peel added to feed on liver fat metabolism and fat deposition in tilapia tilapia; use transcriptomics to analyze related signal regulation pathways, focusing on fat metabolism and inflammatory response; and finally screening differentially expressed genes. The development of this study is helpful to understand the molecular mechanism of apple peel extract powder-mediated liver fat metabolism and inflammatory response in GIFT, and relieve liver stress. It also provides theoretical support for the application of apple peel extract powder as a feed additiion in aquatic products.

Project description:Gene expression profiles by microarray have contributed for a elucidation of an immune-response and a determination of efficiency in vaccination. Recent day, edwardsielosis have caused a fatal damage in the aquaculture of Japanese flounder, Paralichthys olivaceus. However the formalin killed-cell vaccines made from Edwardsiella tarda isolated same fish species were not efficient. Recent our study revealed the mixed FKC vaccine made from the two different type of E. tarda protected Japanese flounder against Edwardsiella tarda infection for long-term. In this study, we analyzed the immune-response of a vaccinated fish kidney using the mixed FKC vaccine against Edwardsiella tarda with an Agilent custom-oligo DNA microarray on 9,573 probes of Japanese flounder. Our study revealed that the mixed FKC vaccine confered a strong immune-response and keeped a efficient for long-term on Japanese flounder.

Project description:In fish, the sex determining mechanisms can broadly be classified as genotypic (GSD), temperature-dependent (TSD), or genotypic plus temperature effects (GSD+TE). For the fish species with TSD or GSD+TE, extremely high or low temperature can affect its sex determination and differentiation. For long time, the underlying changes in DNA methylation that occur during high or low temperature induced sex reversal have not been fully clarified. In this study, we used Nile tilapia as a model to perform a genome-wide survey of differences in DNA methylation in female and male gonads between control and high temperature induced groups using methylated DNA immunoprecipitation (MeDIP). We identified the high temperature induction-related differentially methylated regions (DMRs), and performed functional enrichment analysis for genes exhibiting DMR. These identified differentially methylated genes were potentially involved in the connection between environmental temperature and sex reversal in Nile tilapia. In this study, four samples (control females, CF; control males, CM; induced females, IF; induced males, IM) were analyzed.

Project description:Rainbow trout (Oncorhynchus mykiss) is an important aquaculture fish species that is farmed worldwide, and it is also the most widely cultivated cold water fish in China. This species, a member of the salmonidae family, is an ideal model organism for studying the immune system in fish. Two phenotypes of rainbow trout are widely cultured; wild-type rainbow trout with black skin (WR_S) and yellow mutant rainbow trout with yellow skin (YR_S). Fish skin is an important immune organ, however, little is known about the differences in skin immunity between WR_S and YR_S in a natural flowing water pond aquaculture environment, and very few studies were conducted to investigate the ceRNA mechanism for fish skin.
