Abstract
Cytokines are co-administrated with vaccines or co-expressed in the vaccine virus genome to improve protective efficacy by stimulating immune responses. Using glycosylphosphatidylinositol (GPI) anchoring by attachment to the target cytokine, we constructed recombinant Marek's disease virus (MDV) vaccine strain 301B/1 (v301B/1-rtg-IL-15) that expresses chicken interleukin-15 (IL-15) as the membrane-bound form at the cell surface. We evaluated the vaccine efficacy of v301B/1-rtg-IL-15 given as a bivalent Marek's disease (MD) vaccine in combination with turkey herpesvirus (HVT) against a very virulent plus MDV strain 648A challenge. The efficacy was compared with that of conventional bivalent MD vaccine, as a mixture with HVT plus parental v301B/1 or v301B/1-IL-15, which expresses a natural form of IL-15. The membrane-bound IL-15 expression did not interfere with the virus growth of recombinant v301B/1-rtg-IL-15. However, the MD incidence in birds vaccinated with v301B/1-rtg-IL-15 was higher than that of birds given the conventional bivalent MD vaccine containing parental v301B/1 virus, although the v301B/1-rtg-IL-15 vaccinated group showed increased natural killer cell activation at day 5 postvaccination, the same day as challenge. Overall, the protection of v301B/1-rtg-IL-15 was not improved from that of v301B/1 against very virulent plus MDV challenge.

Abstract
With the rapidly increasing demand for poultry products and the current challenges facing the poultry industry, the application of biotechnology to enhance poultry production has gained growing significance. Biotechnology encompasses all forms of technology that can be harnessed to improve poultry health and production efficiency. Notably, biotechnology-based approaches have fueled rapid advances in biological research, including (a) genetic manipulation in poultry breeding to improve the growth and egg production traits and disease resistance, (b) rapid identification of infectious agents using DNA-based approaches, (c) inclusion of natural and synthetic feed additives to poultry diets to enhance their nutritional value and maximize feed utilization by birds, and (d) production of biological products such as vaccines and various types of immunostimulants to increase the defensive activity of the immune system against pathogenic infection. Indeed, managing both existing and newly emerging infectious diseases presents a challenge for poultry production. However, recent strides in vaccine technology are demonstrating significant promise for disease prevention and control. This review focuses on the evolving applications of biotechnology aimed at enhancing vaccine immunogenicity, efficacy, stability, and delivery.

Abstract
Hepatitis-hydropericardium syndrome (HHS), caused by fowl adenovirus serotype 4 (FAdV-4), has spread on chicken farms worldwide, causing huge economic losses. Currently, the exact mechanism of pathogenesis of FAdV-4 remains unknown. Despite the severe inflammatory damage observed in chickens infected with pathogenic FAdV-4, few studies have focused on the host immune system-virus interactions and cytokine secretion. Host immunity acts as one of the most robust defense mechanisms against infection by pathogens, and cytokines are important in their elimination. However, excessive inflammatory cytokine secretion could contribute to the pathogenesis of FAdV-4. Understanding of the roles of cytokines produced during FAdV-4 infection is important for the study of pathogenicity and for developing strategies to control FAdV-4. Several previous studies have addressed the immune responses to FAdV-4 infection, but there has not been a systematic review of this work. The present review provides a detailed summary of the current findings on cytokine production induced by FAdV-4 infection to accelerate our understanding of FAdV-4 pathogenesis.

Abstract
Infectious laryngotracheitis virus (ILTV) is a cause of main respiratory disease of chickens controlled through live attenuated vaccines. To reduce the risk of adverse effects associated with live vaccines, a recombinant vaccine expressing PH-1 domain of viral glycoprotein B was constructed using the pET expression system under isopropylthiogalactoside (IPTG) induction. The potential immunogenicity of recombinant PH-1 (rPH-1) was evaluated in chickens. Eight-week-old specific-pathogen-free chickens were intramuscularly administered two doses of rPH-1, 25 and 50 μg, alone or with a combination of ISA70 adjuvant. The humoral immune responses were determined up to 3 months postvaccination at 2 weeks apart. The T cell proliferation response was determined on day 28 after primary immunization. The vaccinated birds with rPH-1/ISA70 developed higher and constant-specific anti-ILTV enzyme-linked immunosorbent assay (ELISA) antibodies than in those vaccinated with rPH-1 alone. Coinjection of rPH-1 and adjuvant significantly (p < 0.01) increased the T cell proliferation responses. There were no significant differences in eliciting the immune responses in chickens immunized with the higher dose of the antigen than that with the lower dose. The data indicate the immunogenic efficiency of rPH-1 against ILTV. Vaccination with recombinant proteins offers a preventing option to control the ILTV infection and could be a candidate to replace current live vaccines.

Abstract
Porcine parvovirus (PPV) is one of many pathogens responsible for reproductive failure in pregnant sows. Several studies have reported the appearance of new PPV strains that differ from previous isolates both genetically and antigenically. Thus, the protective effects of commercially inactivated vaccines could not be complete. In South America, the information about PPV is limited. Thus, the aim of the present study was to detect and characterize the PPV strains present in 131 mummies or stillbirths from normal deliveries in sows from a commercial swine farm of Argentina that uses the commercial vaccine. PCR results showed that 17/131 were positive to PPV. Ten of these viruses were isolated and sequenced. All viruses were related to the PPV1 sequence (NADL-2), maintaining the amino acid differences in positions 436 (S–P) and 565 (R–K). This study is the first to report the isolation of PPV in Argentina and the results suggest that PPV can cross the placenta even in vaccinated sows, thus affecting some of the fetuses and being able to cause fetal death in sows without reproductive failure. The results also suggest that vaccination only reduces clinical signs and reproductive disorders and may thus not be a perfect tool to manage PPV infection. This study provides information that needs to be studied in depth to improve strategies to prevent and control PPV infection in swine farms.

Abstract
Gallid alphaherpesvirus 1 (syn. infectious laryngotracheitis virus; ILTV) is the causative agent of infectious laryngotracheitis, a respiratory disease of chickens causing substantial economic losses in the poultry industry every year. Currently, the most efficient way to achieve protection against infection is immunization with live-attenuated vaccines. However, this vaccination strategy entails the risk of generating new pathogenic viruses resulting from spontaneous mutations or from recombination with field strains. This work presents a new approach based on virus-like particles (VLPs) displaying ILTV glycoproteins B (gB) or G (gG) on their surface. The main focus of this pilot study was to determine the tolerability of VLPs delivered in ovo and intramuscularly (i.m.) into chickens and to investigate the nature of the immune response elicited. The study revealed that the new vaccines were well tolerated in hybrid layer chicks independent of the administration method (in ovo or i.m.). Upon in ovo injection, vaccination with VLP-gG led to an antibody response, while a cellular immune response in VLP-gB-immunized chickens was hardly detectable. Since the administration of VLPs had no visible side effects in vivo and was shown to elicit an antibody-based immune response, we anticipate that VLPs will become a valuable platform for the development of new safe vaccines for poultry.

Abstract
Rabbit hemorrhagic disease (RHD) is a highly contagious infection that has caused significant damage to the rabbit industry since 1984. Inactivated vaccines, the currently used prevention measures, are effective in controlling RHD. However, these vaccines are derived from the livers of infected rabbits, which constitutes a major concern in terms of animal welfare and safety. Administration of DNA vaccines in collaboration with appropriate adjuvants, in particular, cytokines, to strengthen the immune response presents a novel optimization strategy to generate more efficient vaccines. In this study, the adjuvant effect of interleukin (IL)-2 co-expression with the VP60 gene in a DNA vaccine was evaluated. In total, four groups of 60 RHD virus (RHDV)-free rabbits (30 days old) were orally or subcutaneously administered recombinant SL7207-pVAX1-IL2-VP60, SL7207-pVAX1-VP60, SL7207-pVAX1 bacteria or the commercial inactive vaccine, and the induced immunity evaluated by challenge with the RHDV(Y8504/China) strain on day 56. The Recombinant SL7207-pVAX1-IL2-VP60 induced a higher level of antibodies than the vaccine SL7207-pVAX1-VP60 and inactivated vaccines to a significant extent. The concentrations of interleukin (IL)-4 were markedly higher than those in groups immunized with the naked or inactive vaccine alone. Furthermore, the fusion gene vaccine provided higher protection (93.33%) after virus challenge relative to immunization with the single gene (SL7207-pVAX1-VP60). The collective results indicate that recombinant SL7207-pVAX1-IL-2-VP60 bacteria exert enhanced protective effects against RHDV and therefore present a strong candidate as a potential vaccine. Moreover, IL-2 enhanced both humoral and cellular responses, highlighting the utility of rabbit IL-2 as an effective adjuvant.

Abstract
Commercial broiler and layer chickens are heavily vaccinated against economically important viral diseases with a view of preventing morbidity, mortality, and production impacts encountered during short production cycles. Hatchery vaccination is performed through in ovo embryo vaccination prehatch or spray and subcutaneous vaccinations performed at the day of hatch before the day-old chickens are being placed in barns with potentially contaminated environments. Commercially, multiple vaccines (e.g., live, live attenuated, and viral vectored vaccines) are available to administer through these routes within a short period (embryo day 18 prehatch to day 1 posthatch). Although the ability to mount immune response, especially the adaptive immune response, is not optimal around the hatch, it is possible that the efficacy of these vaccines depends partly on innate host responses elicited in response to replicating vaccine viruses. This review focuses on the current knowledge of hatchery vaccination in poultry and potential mechanisms of hatchery vaccine-mediated protective responses and limitations.

Abstract
Poultry DNA vaccination studies are regularly being published since 1993. These studies are mainly, but not only, concerned with vaccination against viruses. The different strategies of improving DNA vaccine efficacies are presented. The fate of the vaccine plasmid, immune properties and other applications are described. Despite the compiling preclinical reports, a poultry DNA vaccine is yet unavailable in the market.
DNA vaccination is a promising alternative strategy for developing new human and animal vaccines. The massive efforts made these past 25 years to increase the immunizing potential of this kind of vaccine are still ongoing. A relatively small number of studies concerning poultry have been published. Even though there is a need for new poultry vaccines, five parameters must nevertheless be taken into account for their development: the vaccine has to be very effective, safe, inexpensive, suitable for mass vaccination and able to induce immune responses in the presence of maternal antibodies (when appropriate). DNA vaccination should meet these requirements. This review describes studies in this field performed exclusively on birds (chickens, ducks and turkeys). No evaluations of avian DNA vaccine efficacy performed on mice as preliminary tests have been taken into consideration. The review first describes the state of the art for DNA vaccination in poultry: pathogens targeted, plasmids used and different routes of vaccine administration. Second, it presents strategies designed to improve DNA vaccine efficacy: influence of the route of administration, plasmid dose and age of birds on their first inoculation; increasing plasmid uptake by host cells; addition of immunomodulators; optimization of plasmid backbones and codon usage; association of vaccine antigens and finally, heterologous prime-boost regimens. The final part will indicate additional properties of DNA vaccines in poultry: fate of the plasmids upon inoculation, immunological considerations and the use of DNA vaccines for purposes other than preventing infectious diseases.

Abstract
Viral protein 2 (VP2) of porcine parvovirus (PPV) is the major viral structural protein and is responsible for eliciting neutralizing antibodies in immunized animals. In this study, we constructed and characterized a recombinant yeast vector encoding the VP2 protein, designated as pGAPZαA-VP2. The construct was confirmed by restriction enzyme digestion, PCR, and sequencing and then introduced into P. pastoris strain SMD1168 by electroporation. The expressed VP2 protein was analyzed by SDS-PAGE and western blot. Immunization of mice with the VP2 protein elicited a PPV-specific humoral immune response. Notably, a preparation of VP2 protein containing adjuvant induced a much better antibody response than VP2 alone. Clearly, the adjuvant strongly enhanced the immunogenicity of VP2. This study provides a foundation for the application of the VP2 protein in the clinical diagnosis of PPV and in vaccination against PPV in the future.

Abstract
We had examined the immunogenicity of a series of plasmid DNAs which include neuraminidase (NA) and nucleoprotein (NP) genes from avian influenza virus (AIV). The interleukin-15 (IL-15) and interleukin-18 (IL-18) as genetic adjuvants were used for immunization in combination with the N1 and NP AIV genes. In the first trial, 8 groups of chickens were established with 10 specific-pathogen-free (SPF) chickens per group while, in the second trial 7 SPF chickens per group were used. The overall N1 enzyme-linked immunosorbent assay (ELISA) titer in chickens immunized with the pDis/N1+pDis/IL-15 was higher compared to the chickens immunized with the pDis/N1 and this suggesting that chicken IL-15 could play a role in enhancing the humoral immune response. Besides that, the chickens that were immunized at 14-day-old (Trial 2) showed a higher N1 antibody titer compared to the chickens that were immunized at 1-day-old (Trial 1). Despite the delayed in NP antibody responses, the chickens co-administrated with IL-15 were able to induce earlier and higher antibody response compared to the pDis/NP and pDis/NP+pDis/IL-18 inoculated groups. The pDis/N1+pDis/IL-15 inoculated chickens also induced higher CD8+ T cells increase than the pDis/N1 group in both trials (P<0.05). The flow cytometry results from both trials demonstrated that the pDis/N1+pDis/IL-18 groups were able to induce CD4+ T cells higher than the pDis/N1 group (P<0.05). Meanwhile, pDis/N1+pDis/IL-18 group was able to induce CD8+ T cells higher than the pDis/N1 group (P<0.05) in Trial 2 only. In the present study, pDis/NP was not significant (P>0.05) in inducing CD4+ and CD8+ T cells when co-administered with the pDis/IL-18 in both trials in comparison to the pDis/NP. Our data suggest that the pDis/N1+pDis/IL-15 combination has the potential to be used as a DNA vaccine against AIV in chickens.

Abstract
Infectious laryngotracheitis (ILT) is an important respiratory disease of chickens and annually causes significant economic losses in the poultry industry world-wide. ILT virus (ILTV) belongs to alphaherpesvirinae and the Gallid herpesvirus 1 species. The transmission of ILTV is via respiratory and ocular routes. Clinical and post-mortem signs of ILT can be separated into two forms according to its virulence. The characteristic of the severe form is bloody mucus in the trachea with high mortality. The mild form causes nasal discharge, conjunctivitis, and reduced weight gain and egg production. Conventional polymerase chain reaction (PCR), nested PCR, real-time PCR, and loop-mediated isothermal amplification were developed to detect ILTV samples from natural or experimentally infected birds. The PCR combined with restriction fragment length polymorphism (RFLP) can separate ILTVs into several genetic groups. These groups can separate vaccine from wild type field viruses. Vaccination is a common method to prevent ILT. However, field isolates and vaccine viruses can establish latent infected carriers. According to PCR-RFLP results, virulent field ILTVs can be derived from modified-live vaccines. Therefore, modified-live vaccine reversion provides a source for ILT outbreaks on chicken farms. Two recently licensed commercial recombinant ILT vaccines are also in use. Other recombinant and gene-deficient vaccine candidates are in the developmental stages. They offer additional hope for the control of this disease. However, in ILT endemic regions, improved biosecurity and management practices are critical for improved ILT control.

Abstract
Background DNA vaccines offer several advantages over conventional vaccines in the development of effective vaccines against avian influenza virus (AIV). However, one of the limitations of the DNA vaccine in poultry is that it induces poor immune responses. In this study, chicken interleukin (IL) -15 and IL-18 were used as genetic adjuvants to improve the immune responses induced from the H5 DNA vaccination in chickens. The immunogenicity of the recombinant plasmid DNA was analyzed based on the antibody production, T cell responses and cytokine production, following inoculation in 1-day-old (Trial 1) and 14-day-old (Trial 2) specific-pathogen-free chickens. Hence, the purpose of the present study was to explore the role of chicken IL-15 and IL-18 as adjuvants following the vaccination of chickens with the H5 DNA vaccine. Results The overall HI antibody titer in chickens immunized with pDis/H5 + pDis/IL-15 was higher compared to chickens immunized with pDis/H5 (p < 0.05). The findings revealed that the inoculation of the 14-day-old chickens exhibited a shorter time to achieve the highest HI titer in comparison to the inoculation of the 1-day-old chickens. The cellular immunity was assessed by the flow cytometry analysis to enumerate CD4+ and CD8 + T cells in the peripheral blood. The chickens inoculated with pDis/H5 + pDis/IL-15 demonstrated the highest increase in CD4+ T cells population relative to the control chickens. However, this study revealed that pDis/H5 + pDis/IL-15 was not significant (P > 0.05) in inducing CD8+ T cells. Meanwhile, with the exception of Trial 1, the flow cytometry results for Trial 2 demonstrated that the pDis/H5 + pDis/IL-18 inoculated group was able to trigger a higher increase in CD4+ T cells than the pDis/H5 group (P < 0.05). On the other hand, the pDis/H5 + pDis/IL-18 group was not significant (P > 0.05) in modulating CD8+ T cells population in both trials. The pDis/H5 + pDis/IL-15 inoculated group showed the highest IL-15 gene expression in both trials compared to other inoculated groups (P < 0.05). Similar results were obtained for the IL-18 expression where the pDis/H5 + pDis/IL-18 groups in both trials (Table 8) were significantly higher compared to the control group (P < 0.05). However, the expressions of other cytokines remained low or undetected by GeXP assay. Conclusions This study shows the diverse immunogenicity of pDis/H5 co-administered with chicken IL-15 and IL-18,with pDis/H5 + pDis/IL-15 being a better vaccine candidate compared to other groups.
