Protection against virulent Brucella spp. by gamma-irradiated B. ovis in BALB/c mice model
Purpose Brucella spp. is a zoonosis that causes undulant fever in humans and abortion in livestock worldwide. Lately, it was conveyed that vaccines developed by irradiation have induced a strong cellular and humoral immune response which have made these types of vaccines highly effective. Materials and Methods In this study, we aimed to use the gamma-irradiated B. ovis as a vaccine and to study the humoral immune response and cytokines production in order to evaluate it for protecting mice against B. abortus 544, B. melitensis 16M, and B. ovis. Results The humoral immune response in immunized mice with gamma-irradiated B. ovis showed a lasting for 8 weeks after immunization. Moreover, immunoglobulin G (IgG), IgG1, IgG2a, and IgG2b isotypes antibodies against B. ovis were observed after 4 and 8 weeks of the last immunization. It was noticed that the production of tumor necrosis factor-α, interferon-γ, and interleukin (IL)-10 continued after 4 and 8 weeks by splenocytes from immunized BALB/c mice, while no production of IL-4 or IL-5 was observed. Conclusion Our results indicate that the protection of BALB/c mice against B. melitensis 16M, B. abortus 544, and B. ovis was induced and the developed vaccine at our laboratory could stimulate similar protection to those induced by the traditional vaccine.
期刊介绍:
Clin Exp Vaccine Res, the official English journal of the Korean Vaccine Society, is an international, peer reviewed, and open-access journal. It covers all areas related to vaccines and vaccination. Clin Exp Vaccine Res publishes editorials, review articles, special articles, original articles, case reports, brief communications, and correspondences covering a wide range of clinical and experimental subjects including vaccines and vaccination for human and animals against infectious diseases caused by viruses, bacteria, parasites and tumor. The scope of the journal is to disseminate information that may contribute to elaborate vaccine development and vaccination strategies targeting infectious diseases and tumors in human and animals. Relevant topics range from experimental approaches to (pre)clinical trials for the vaccine research based on, but not limited to, basic laboratory, translational, and (pre)clinical investigations, epidemiology of infectious diseases and progression of all aspects in the health related issues. It is published printed and open accessed online issues (https://ecevr.org) two times per year in 31 January and 31 July. Clin Exp Vaccine Res is linked to many international databases and is made freely available to institutions and individuals worldwide
