Abstract
Poultry is the first source of animal protein for human consumption. In a changing world, this sector is facing new challenges, such as a projected increase in demand, higher standards of food quality and safety, and reduction of environmental impact. Chicken coccidiosis is a highly widespread enteric disease caused by Eimeria spp. which causes significant economic losses to the poultry industry worldwide; however, the impact on family poultry holders or backyard production-which plays a key role in food security in small communities and involves mainly rural women-has been little explored. Coccidiosis disease is controlled by good husbandry measures, chemoprophylaxis, and/or live vaccination. The first live vaccines against chicken coccidiosis were developed in the 1950s; however, after more than seven decades, none has reached the market. Current limitations on their use have led to research in next-generation vaccines based on recombinant or live-vectored vaccines. Next-generation vaccines are required to control this complex parasitic disease, and for this purpose, protective antigens need to be identified. In this review, we have scrutinised surface proteins identified so far in Eimeria spp. affecting chickens. Most of these surface proteins are anchored to the parasite membrane by a glycosylphosphatidylinositol (GPI) molecule. The biosynthesis of GPIs, as well as the role of currently identified surface proteins and interest as vaccine candidates has been summarised. The potential role of surface proteins in drug resistance and immune escape and how these could limit the efficacy of control strategies was also discussed.

Abstract
Coccidiosis caused by protozoan parasites of the genus Eimeria has a severe economic impact on commercial production worldwide. Micronemes of Eimeria play important roles in invading intestinal cell processes. In this study, the DNA vaccine expressing Eimeria tenella microneme protein 3 (EtMIC3) was constructed to evaluate its immune protective effect against E. tenella infection in chickens. The results demonstrated that chickens immunized with pVAX-EtMIC3 produced strong immune responses in the body, as shown by significant lymphocyte proliferation, cytokine production, and antibody responses. The average body weight gains of chickens in all the vaccinated groups were higher than those of non-vaccinated and challenged groups. In general, oocyst shedding was reduced, and bloody feces and gut lesion scores decreased. In addition, the survival rate of the immunized chickens increased compared to that of the unvaccinated and challenged control chickens. In summary, this study indicated that pVAX-EtMIC3 could induce protective immune effects against coccidiosis and that EtMIC3 is a potential vaccine candidate against coccidiosis.

Abstract
Coccidiosis is a widely distributed disease with higher mortality and morbidity, which is caused by several species of protozoan parasites belonging to the genus Eimeria and recognized as a serious challenge for the poultry industry. This research was conducted to construct the recombinant plasmid pET32a(+)-ADF-linker-3-1E of Eimeria acervulina (E. acervulina) of the chicken and test the bioactivity of the ADF-linker-3-1E protein. The ADF-linker-3-1E gene of E. acervulina of the chicken was cloned by splicing by overlap extension by the polymerase chain reaction (SOE-PCR) and then inserted into the pET32a(+) to construct the recombinant plasmid pET32a(+)-ADF-linker-3-1E. The recombinant plasmid was transformed into Escherichia coli Rosetta (DE3) competent cells and then induced by IPTG (0.6 mmol/L). The expressed product in the culture medium was identified by the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The bioactivity of the ADF-linker-3-1E protein was tested by Western blotting. The result showed that the amplified ADF-linker-3-1E gene was about 1346 bp. The PCR amplification with the recombinant plasmid pET-32a(+)-ADF-linker-3-1E as a template resulted in a special band of 1346 bp. The digested products resulted in two fragments of 1346 bp target fragment and 5.9 kb pET-32a(+)-vector fragment. The results indicated that the ADF-linker3-1E gene was successfully inserted into the pET-32a(+)-vector. The expressed products in the culture medium resulted in a single band of approximately 54.8 kDa by SDS-PAGE. Western blotting analysis indicated that the recombinant protein could be reacted specifically with His-Tag(2A8) Mouse mAb. This study indicated that the ADF-linker-3-1E protein with good bioactivity was successfully obtained, which laid a foundation for the exploitation of the nuclear vaccine by using the ADF-linker-3-1E protein.

Abstract
This experiment was conducted to study the protective efficacy of recombinant plasmid pET32a(+)-ADF-3-1E in coccidian-infected breeding chickens. The 7-day-old chickens were randomly divided into five groups: a recombinant plasmid pET32a(+)-ADF-3-1E group, a pET32a(+)-ADF group, a pET32a(+)-3-1E group, a control group, and an infection control group. The chickens were immunized intramuscularly with recombinant plasmid DNA in a dose of 200 μg, respectively, and a booster vaccination was given at the same dosage 1 week later. The peripheral blood T lymphocyte proliferation, serum IgG antibody response, and levels of interleukin 2 (IL-2) and interferon gamma (IFN-γ) were detected, respectively. The chickens were inoculated with 4 × 10(6) Eimeria acervulina-sporulated oocysts (Baoding strain) on the seventh day after the last immunization to evaluate the protective efficiency of the recombinant plasmid DNA. The results showed that the lymphocyte proliferation, serum IgG antibody, and IL-2 and IFN-γ levels in recombinant plasmid DNA group were significantly higher than those in control group (P < 0.01). The lymphocyte proliferation, serum IgG antibody, and IL-2 and IFN-γ levels in pET32a(+)-ADF-3-1E group were significantly higher than those in pET32a(+)-3-1E group and pET32a(+)-ADF group, respectively (P < 0.05). It indicated that the pET32a(+)-ADF-3-1E could produce stronger immune responses. The relative body weight gain rate in pET32a(+)-ADF-3-1E group was 88.36 %, which was significantly higher than that in control group (P < 0.05) and infection control group (P < 0.01). The reductions of oocyst production and lesion scores in pET32a(+)-ADF-3-1E group were 67.88 and 67.13 %, respectively. The oocyst excretion and the lesion score of chickens in pET32a(+)-ADF-3-1E group were lower than those in infection control group, respectively. Anticoccidial index (ACI) value in group immunized with pET32a(+)-ADF-3-1E was 169.82. ACI value of 160-179 was considered as effective. These results demonstrated that the pET32a(+)-ADF-3-1E recombinant plasmid DNA could effectively improve the cellular responses and humoral immune responses of the chickens, and it might provide protection against coccidiosis in chickens.

Abstract
To evaluate the biosafety of the plasmid pcDNA3-1E of Eimeria acervulina in chicken, two-week-old chickens were injected intramuscularly with the plasmid pcDNA3-1E at dose of 50 μg/chicken. At the 15 days post-injection, the tissue samples were collected, the total DNA was extracted, and the 3-1E gene was amplified by PCR. Genomic DNA was first purified away from free plasmid using gel electrophoresis, and then assayed for integrated plasmid using PCR amplification of the 3-1E gene. Simultaneously, the environmental dejection samples were collected, the total bacterial DNA was extracted and then transfer of the pcDNA3-1E gene was detected by PCR amplification of the 3-1E gene. Two-week-old chickens were injected intramuscularly with the plasmid pcDNA3-1E with three dosage groups of 100 μg, 500 μg and 2500 μg/chicken for 14 days respectively, and with physiological saline at dose of 2500 μL/chicken as control group for acute toxicity test. A target band of 583 bp was obtained by PCR with chicken genomic DNA as template. If the chicken genomic DNA was purified, no target band could be obtained. It showed that the recombinant plasmid pcDNA3-1E existed in tissues, and no genomic integration of DNA plasmid was detected in the immunized chickens. No target band was found by PCR with environmental dejection bacteria genomic DNA as template. It showed that integration and transfer phenomenon did not exist in environment. The acute toxicity results showed the typical clinical symptoms did not occur in the inoculated chickens, the blood biochemical indices and viscera configuration were not affected significantly in the inoculated group and control group (P>0.05). The results showed that the plasmid pcDNA3-1E was safe and suitable for chicken clinical trials.
