Identification And Characterization Of A Novel Protective Antigen, Sesec_00396 Of Streptococcus Equi Ssp. Zooepidemicus, Li Yi, Weiping Yang, Jinpeng Li, Shaohui Wang, Yang Wang
The Thai Journal of Veterinary Medicine
Streptococcus equi ssp. zooepidemicus (SEZ) is responsible for a wide variety of infections in many animal species. Studies aimed at developing safe and effective vaccines against SEZ infections are thus of great interest. SeseC_00396 was a novel protein identified in the previous study. In this study, recombinant SeseC_00396 of SEZ was expressed and showed a strong immunoreactivity with mini-pig convalescent sera. Studies in mice have revealed that the recombinant protein induced a marked antibody response which was associated with protection against SEZ infection. The hyperimmune sera against SeseC_00396 could efficiently kill the bacteria. In addition, it was also found that …

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the important RNA viruses that affects swine production worldwide. To better improve vaccine efficacy, understanding the molecular mechanisms and viral-host interaction is important to increase the knowledge of vaccine response. The objective of this study was to investigate the expression levels of miR-29a and IFN-γ in pigs that received modified live PRRSV vaccine. The study revealed that both miR-29a and IFN-γ transcript levels increased in vivo early, at day 3 post vaccination, whereas levels of miR-29a and IFN-γ mRNA were not different at day 7 post vaccination. Our study is …

The objective of this study was to evaluate type 2 porcine reproductive and respiratory syndrome virus (PRRSV)-based modified live vaccine in a herd with concurrent circulation of type 1 and type 2 PRRSV. Type 2 PRRSV-based modified live vaccine improved average daily gain by 48.24 grams/pig/day (631.17 grams/pig/day in the vaccinated group vs 582.93 grams/pig/day in the unvaccinated group; P < 0.05). Pathological examination indicated that the vaccination effectively reduced microscopic lung lesions compared with the control animals. The protection of this vaccine against type 1 and type 2 PRRSV provides clinical control of co-infection with both genotypes under field conditions.

Bovine tuberculosis (BTB) is a contagious zoonotic disease that causes serious public health concerns. Cervidae are highly susceptible to BTB and it has been diagnosed in various deer species. In order to develop BTB eradication and control program, Mycobacterium bovis Bacille Calmette Guerin (BCG) vaccination has been studied in cervids. In this study 15 rusa deer were tested for responsiveness to mycobacterial reaction using a comparative cervical skin test (CCT). The rusa deer were divided into 2 groups; BCG vaccination group, which were inoculated with a single dose of 2x106 cfu M. bovis BCG Tokyo subcutaneously (n=8) and control group …
