Project description:In this study we attempt to elucidate some of the pathways involved in the immune response to vaccination and subsequent disease challenge using a transcriptomic approach. We exposed, via intra-peritoneal injection, three months old Asian seabass (Lates calcarifer) to a Streptococcus iniae vaccine. A control group was also set up where no vaccine was injected. Spleen and head kidney samples were collected at one and seven days post vaccination for transcriptomic analysis. At this point, there are four groups per organ: Day 1 vaccinated, Day 1 control, Day 7 vaccinated and Day 7 control. Subsequently, a pathogen challenge was carried out three weeks later and spleen and head kidneys were sampled at 25-29 hours post challenge for transcriptomic analysis. For control, mock challenged was carried out. At this point, there are four groups per organ: unvaccinated challenged, unvaccinated mock challenged, vaccinated challenged and vaccinated mock challenged. Total 57 samples. Spleen samples: At Day 1 and Day 7 post vaccination, 4 spleens were analyzed for each of the D1 control and D1 vaccinated groups and 3 spleens were analyzed for each of the D7 control and D7 vaccinated groups (total = 14 samples). At post pathogen challenge, 4 spleens were analyzed for each of these three groups - unvaccinated mock challenged, vaccinated challenged and vaccinated mock challenged and 3 spleens for the unvaccinated challenged group (total = 15 samples). Head Kidney samples: At Day 1 and Day 7 post vaccination, 3 head kidneys were analyzed for the control and vaccinated groups for both time points (total = 12 samples). At post pathogen challenge, 4 head kidneys were analyzed for each of the groups: unvaccinated challenged, unvaccinated mock challenged, vaccinated challenged and vaccinated mock challenged (total = 16 samples).

Project description:Transcriptome Analysis of the Lates calcarifer Immune Response Towards Cryptocaryon irritans Infection

Project description:Differential Transcriptomic Response in the Head kidney Following Infection of Asian Seabass with Vibrio alginolyticus
| PRJNA997377 | ENA
Project description:Cryptocaryon irritans is the causative agent of white spot disease that infects virtually all marine teleost including Lates calcarifer. We undertook to gain an informative snapshot of the host’s transcriptomic response during the course of infection. Liver and spleen cDNA libraries-based L. calcarifer cDNA microarray were used as a tool to oversee the infection response. Parasites infection was carried out on juvenile fish for four days, and total RNA was extracted from the daily harvested infected liver. cDNAs synthesized from respective daily pooled total RNA were labelled and hybridized onto the L. calcarifer chip. The majority of infection-induced genes are acute phase proteins (APP) with hepcidin, C-type lectin and serum amyloid A being the most up-regulated products.

Project description:Barramundi (Lates calcarifer) is an important farmed marine food fish species. Its compact genome (approximately 700 Mb) is among the smallest genomes of food fish species. We established a first-generation genetic linkage map of Barramundi with a mapping panel containing three parents (two males and one female) and 93 progeny. A total of 240 microsatellite markers were mapped into 24 linkage groups. Among these markers, 10 were located in ESTs and known genes. The total lengths of the female and male maps were 873.8 and 414.5 cM with an average marker spacing of 6.20 and 4.70 cM, respectively. Comparing the flanking sequences of the 240 Barramundi microsatellites with the assembled whole-genome sequences of Tetraodon nigrovidiris revealed 55 homologous sequences located in 19 of the 21 chromosomes of T. nigrovidiris. The map will not only enable the mapping of quantitative trait loci, but also provide new resources for understanding the evolution of fish genomes.
