Abstract
Leptospirosis is a debilitating infectious disease that detrimentally affects both animals and humans; therefore, disease prevention has become a high priority to avoid high incidence rates of disease in the herd and break the transmission cycle to humans. Thus, there remains an important unmet need for a prophylactic vaccine that can provide long-term immunity against leptospirosis in cattle. Herein, a novel vaccine formulation was developed where poly(diaminosulfide) polymer was employed to fabricate microparticles encapsulating the antigen of Leptospira borgpetersenii serovar Hardjo strain HB15B203 (L203-PNSN). A prime-boost vaccination with a L203-PNSN microparticle formulation increased the population of L203-specific CD3+ T cells and CD21+ B cells to levels that were significantly higher than those of cattle vaccinated with L203-AlOH or the vehicle control (empty PNSN microparticles and blank AlOH). In addition, L203-PNSN was demonstrated to stimulate durable humoral immune responses as evidenced by the increases in the antibody serum titers following the vaccination. It was also found that cattle vaccinated with L203-PNSN produced higher macroscopic agglutinating titers than cattle in other groups. Thus, it can be concluded that L203-PNSN is a novel first-in-class microparticle-based Leptospira vaccine that represents a powerful platform with the potential to serve as a prophylactic vaccine against leptospiral infection in cattle.

Abstract
Citreoviridin, a mycotoxin produced by Penicillium citreonigrum is a common contaminant of wide range of agri-products and detrimental to human and animal health. Therefore it is important to develop a rapid, sensitive, and specific immunoassay for citreoviridin detection. In this study, polyclonal antibody against citreoviridin was developed. For the preparation of citreoviridin-bovine serum albumin conjugate (CIT-BSA), hydroxyl groups on adjacent carbon atoms were oxidized by sodium periodate, so the product with reactive aldehyde residues was suitable for coupling with amine. Anti-citreoviridin polyclonal antibody was prepared by immunizing mice with CIT-BSA conjugate. The specificity and sensitivity of the polyclonal antibody was determined by indirect competitive ELISA. Results showed that the IC50 value of the polyclonal antibody was 0.56 μg/mL and no cross-reactivity was found between antiserum and other mycotoxins used in the experiment. The citreoviridin recovery rates by this polyclonal antibody were calculated through rice powder spiked by artificial citreoviridin. The recovery rates ranged were found from 70.5 ± 0.08 % to 94.7 ± 0.09% for inter-assay, and from 77.5 ± 0.04% to 95.4 ± 0.18% for intra-assay, which indicated that this polyclonal antibody could detect trace amount of CIT from the tested samples. Consequently, this study provided a specific and sensitive anti-citreoviridin polyclonal antibody, which made the determination of citreoviridin easier, quicker, and more accurate.

Abstract
Incorrect use of tylosin and tilmicosin could result in allergy and select resistance. To monitor the illegal use of these antibiotics in animals, a monoclonal-based indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) has been established. Several haptens were synthesized and conjugated to carrier protein. Female Balb/c mice were inoculated with the four different conjugates to produce monoclonal antibodies according to the schemes of immunization. Aftercell fusion and culture several times, nine hybridoma cell lines were isolated. Only one, 3C4 that has isotype IgG2a, was selected for detailed study. The cross-reactivity of the monoclonal antibody 3C4 to tylosin and tilmicosin was 100% and 51% respectively. The standard curves based on the tylosin and tilmicosin matrix calibration ranged from 2.5 to 40 μg L(-1), with an IC(50) value of 6.1 μg L(-1) and 12.1 μg L(-1), respectively. The limits of detection of the ic-ELISA ranged from 5.1 μg kg(-1) to 13.8 μg kg(-1) in edible animal tissues. The recoveries were 74.1% to 120.7% with less than 18.6% of the coefficient of variation when tylosin and tilmicosin were spiked in various biological matrices with the concentrations of 25.0-200.0 μg kg(-1). Good correlations between the results of the ic-ELISA and high performance liquid chromatography were observed in the incurred tissues. These results suggest that the ic-ELISA is a sensitive, accurate and low-cost method that would be a useful tool for the screening of the residues of tylosin and tilmicosin in muscle, liver, milk, honey and eggs.

Abstract
Tetracycline (TC) is a broad-spectrum antibiotic used increasingly in animal husbandry to treat diseases or to promote growth as feed additives. To avoid using labor-intensive instrumental methods to detect residues of TC in food and food products, a simple and convenient indirect heterologous competitive enzyme-linked immunosorbent assay (ELISA) method for TC was developed using polyclonal antibody prepared in this study. Three new immunogens, TC-o-tolidine-bovine serum albumin (BSA), TC- 4-aminobenzoic acid-cationized BSA (cBSA), and TC-1,1'-carbonyldiimidazole-cBSA, were synthesized in this research to develop anti-TC antibodies. All antibodies raised in rabbits and coating antigens synthesized were screened and characterized using homologous and heterologous ELISA formats to select the best combination. An optimized ELISA gave an IC50 value of 3.92 mug/mL toward TC in PBS buffer. The specificity of the assay was studied by measuring cross-reactivity of the antibody with the structurally closely related compounds of chlortetracycline (112%) and oxytetracycline (<2%). The recovery rates from the TC-fortified raw milk samples were in the range of 74-116%, while the intra- and interassay coefficients of variation were <14.5 and <25.0, respectively.
