Abstract
Protection facilitated by the widespread use of mineral oil adjuvanted injection vaccines in salmonid fish comes with adverse effects of varying severity. In this study, we characterized the immunological profiles of two alternative vaccine formulations, both with proven efficacy and an improved safety profile in rainbow trout. Experimental injection vaccines were prepared on an identical whole-cell Aeromonas salmonicida bacterin platform and were formulated with CpG oligodeoxynucleotides, a liposomal (CAF01) or a benchmark mineral oil adjuvant, respectively. A naïve group, as well as bacterin and saline-injected groups were also included. Following administration, antigen-specific serum antibody titers, the tissue distribution of immune cell markers, and the expression of immune-relevant genes following the in vitro antigenic restimulation of anterior kidney leukocytes was investigated. Immunohistochemical staining suggested prolonged antigen presentation for the particulate formulations and increased mucosal presence of antigen-presenting cells in all immunized fish. Unlike the other immunized groups, the CAF01 group only displayed a transient elevation in specific antibody titers and immunohistochemical observations, and the transcription data suggest an increased role of cell-mediated immunity for this group. Finally, the transcription profile of the CpG formulation approached that of a TH1 profile. When compared to the benchmark formulation, CAF01 and CpG adjuvants induce slight, but distinct differences in the resulting protective immune responses. This is important, as it allows a broader immunological approach for the future development of safer vaccines.

Abstract
IgM antibody diversity induced by viral infection in teleost fish sera remains largely unexplored despite several studies performed on their transcript counterparts in lymphoid organs. Here, IgM binding to microarrays containing ~20,000 human proteins was used to study sera from carp (Cyprinus carpio) populations having high titers of viral neutralization in vitro after surviving an experimental infection with cyprinid herpes virus 3 (CyHV-3). The range of diversity of the induced antibodies was unexpectedly high, showing CyHV-3 infection-dependent, non-specific IgM-binding activity of a ~20-fold wider variety than that found in sera from healthy carp (natural antibodies) with no anti-CyHV-3 neutralization titers. An inverse correlation between the IgM-binding levels in healthy versus infection-survivor/healthy ratios suggests that an infection-dependent feed back-like mechanism may control such clonal expansion. Surprisingly, among the infection-expanded levels, not only specific anti-frgIICyHV-3 and anti-CyHV-3 IgM-binding antibodies but also antibodies recognizing recombinant fragment epitopes from heterologous fish rhabdoviruses were detected in infection-survivor carp sera. Some alternative explanations for these findings in lower vertebrates are discussed.

Abstract
In an effort to reduce the frequency and severity of adverse reactions seen from the use of mineral oil adjuvants in salmonid fish, the effects of two alternative adjuvants were assessed, focusing on the induction of adverse effects as well as protection. Using rainbow trout (Oncorhynchus mykiss) as recipients, injection vaccines based on formalin-inactivated Aeromonas salmonicida subspecies salmonicida were formulated with CpG oligodeoxynucleotides, the liposomal cationic adjuvant formulation 01 (CAF01) or with Freund’s incomplete adjuvant and administered intraperitoneally. Control groups of unvaccinated, Tris-buffered saline-injected or bacterin-injected individuals were included, and each group included in the study held a total number of 240 individuals. Subsequently, individuals from each group were examined for differences in Fulton’s condition factor, macro- and microscopic pathological changes, as well as protection against experimental infection with A. salmonicida. While adverse effects were not eliminated, reductions in microscopic and macroscopic adverse effects, in particular, were seen for both the nucleotide- and liposome-based vaccine formulations. Furthermore, the induced protection appears similar to that of the benchmark formulation, thus introducing viable, potential alternative types of adjuvants for use in future fish vaccines.

Abstract
Prophylactic measures against Aeromonas salmonicida subsp. salmonicida, the causative agent of furunculosis, have been an active field of research for decades, with studies mainly focused on Atlantic salmon (Salmo salar). In the present study we have examined the protective and adverse effects of mineral oil-adjuvanted injection vaccines on rainbow trout (Oncorhynchus mykiss). A commercial vaccine and an experimental auto vaccine, as well as their respective adjuvant formulations alone were used to evaluate their individual effects, both prior to and during an experimental waterborne infection challenge. Macro- and microscopic examination revealed signs of vaccine-induced adverse effects from 10 weeks to 14 months post vaccination. Both vaccines induced statistically significant protection during the experimental challenge (P=0.018 for both vaccines), as well as significantly elevated levels of specific circulating antibodies prior to and during the experimental challenge when compared to an unvaccinated control group. During the early, critical time points of the infection, both vaccines appeared to protect against pathological changes to the liver and spleen, which provides a probable explanation for the reduced mortality seen in the vaccinated groups. A significant correlation was found between the level of A. salmonicida-specific antibodies measured prior to challenge and the endpoint survival of each group after the experimental infection, and furthermore, the levels of these antibodies remained elevated for at least 14 months post vaccination.

Abstract
Time-course and organ transcriptional response profiles in rainbow trout Oncorhynchus mykiss were studied after oral DNA-vaccination with the VP2 gene of the infectious pancreatic necrosis virus (IPNV) encapsulated in alginates. The profiles were also compared with those obtained after infection with IPNV. A group of immune-related genes (stat1, ifn1, ifng, mx1, mx3, il8, il10, il11, il12b, tnf2, mhc1uda, igm and igt) previously selected from microarray analysis of successful oral vaccination of rainbow trout, were used for the RTqPCR analysis. The results showed that oral VP2-vaccination qualitatively mimicked both the time-course and organ (head kidney, spleen, intestine, pyloric ceca, and thymus) transcriptional profiles obtained after IPNV-infection. Highest transcriptional differential expression levels after oral vaccination were obtained in thymus, suggesting those might be important for subsequent protection against IPNV challenges. However, transcriptional differential expression levels of most of the genes mentioned above were lower in VP2-vaccinated than in IPNV-infected trout, except for ifn1 which were similar. Together all the results suggest that the oral-alginate VP2-vaccination procedure immunizes trout against IPNV in a similar way as IPNV-infection does while there is still room for additional improvements in the oral vaccination procedure. Some of the genes described here could be used as markers to further optimize the oral immunization method.

Abstract
Induction of neutralizing antibodies and protection by oral vaccination with DNA-alginates of rainbow trout Oncorhynchus mykiss against infectious pancreatic necrosis virus (IPNV) was recently reported. Because orally induced immune response transcript gene profiles had not been described yet neither in fish, nor after IPNV vaccination, we studied them in head kidney (an immune response internal organ) and a vaccine entry tissue (pyloric ceca). By using an oligo microarray enriched in immune-related genes validated by RTqPCR, the number of increased transcripts in head kidney was higher than in pyloric ceca while the number of decreased transcripts was higher in pyloric ceca than in head kidney. Confirming previous reports on intramuscular DNA vaccination or viral infection, mx genes increased their transcription in head kidney. Other transcript responses such as those corresponding to interferons, their receptors and induced proteins (n=91 genes), VHSV-induced genes (n=25), macrophage-related genes (n=125), complement component genes (n=176), toll-like receptors (n=31), tumor necrosis factors (n=32), chemokines and their receptors (n=121), interleukines and their receptors (n=119), antimicrobial peptides (n=59), and cluster differentiation antigens (n=58) showed a contrasting and often complementary behavior when head kidney and pyloric ceca were compared. For instance, classical complement component transcripts increased in head kidney while only alternative pathway transcripts increased in pyloric ceca, different β-defensins increased in head kidney but remained constant in pyloric ceca. The identification of new gene markers on head kidney/pyloric ceca could be used to follow up and/or to improve immunity during fish oral vaccination.

Abstract
OBJECTIVE Epstein-Barr virus (EBV) infection is an established risk factor for B-cell lymphomas in Human Immunodeficiency virus (HIV)-1 infected patients. A disturbed EBV-host relationship is seen in patient groups with a high risk for EBV-associated lymphomas. We have analysed this relationship by measuring EBV-DNA in the blood of HIV-1 carriers. METHOD EBV-DNA load in B-cells was monitored by PCR in non- or insufficiently antiretroviral treated and rgp160-vaccinated HIV-patients. RESULTS Both asymptomatic HIV-infected and AIDS-patients showed a 25-40-fold increase in the number of B cell associated EBV-DNA copies compared to healthy controls. Patients included in a vaccine trial with recombinant HIV gp160 showed a 5-fold increase of EBV load compared to non-immunised patients and a 50-fold increase compared to healthy controls. There was no difference whether they received vaccine or "placebo". Vaccinated patients with a history of symptomatic primary HIV-1 infection (PHI) had a 280-fold increase in median EBV load compared to healthy controls, thus suggesting a synergistic effect between the vaccination and PHI, which hypothetically could affect lymphoma risk. CONCLUSIONS We recommend analysis of EBV-load and long term follow up of lymphoma risk in all therapeutic HIV-1 vaccination trials.

Abstract
The histiophagous scuticociliate parasite Philasterides dicentrarchi is an emergent pathogen in aquaculture and causes significant economic losses on turbot (Scophthalmus maximus) farms. In this study, the surface antigens (Ag) of the parasite were encapsulated and covalently linked to a polymeric microparticle formulation composed of two biodegradable polymers (chitosan and Gantrez). The antigenicity of the formulation and the protection provided were compared in mice and turbot. This formulation induced a higher antibody (Ab) response in mice at doses of 5mg of microspheres (MS) conjugated with approximately 230 μg of Ag (MS-Ag(c)). However, Ab levels were significantly lower than in mice vaccinated with the same concentration of Ag in complete Freund's adjuvant (FCA). In turbot, the MS-Ag(c) formulation induced a higher level of Abs than that induced by the same vaccine emulsified in FCA. The challenge experiments performed with P. dicentrarchi and vaccinated turbot also showed a clear correlation between Ab levels and survival levels. Growth was significantly affected in fish vaccinated with FCA, but not in fish vaccinated with MS. The high adjuvant capacity of MS, together with its biodegradability and low toxicity to fish, makes this new vaccine an economical, effective and safe alternative to oil-based adjuvants for the immunoprophylaxis of scuticociliatosis in turbot.

Abstract
This case report describes a 52-y-old male patient who, one week after influenza vaccination, presented with abdominal symptoms: pain in the right epigastrium followed by liver dysfunction and pyrexia, as well renal failure, muscles pain and consciousness disorders. Immune-complex-like disease and Enterobacter cloacae sepsis due to cholelithic cholecystitis were diagnosed. In this case, a correlation between vaccination and immune complex-like-disease was suspected based on the onset of symptoms a few days after vaccination and clinical improvement after plasmapheresis. The etiopathogenesis of immune-complex-like disease in this case possibly could relate to the similarity of the vaccine antigens and E. cloacae antigens as well a genetic predisposition.
