Evaluation of Humoral and Cell-mediated Immunity of Two Capripoxvirus Vaccine Strains against Lumpy Skin Disease Virus
نویسندگان
چکیده مقاله:
Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were vaccinated with two available LSD vaccines. These vaccines were live attenuated sheep pox and goat pox vaccine strains. To evaluate vaccine-induced immune responses, whole blood and serum samples were collected up to 5 weeks post vaccination from both vaccinated and control groups. Results: The findings showed that, lymphocyte proliferation index in response to recall antigen in goat pox vaccine was higher than sheep pox vaccine in all time-point of experiments, and this difference was significant in weeks 1 and 5 post vaccination (p<0.05). Although the levels of antibody production in both vaccinated groups was almost the similar, and there was no statistically significant difference, but in goat pox vaccine slightly higher than sheep pox vaccine. Also, the interferon gamma and IL-4 production in goat pox vaccine were higher than sheep pox vaccine in all-time point and statistically significant at week 3 post vaccination (p< 0.05). Conclusions: From this study we found that live attenuated goat pox vaccine induced high level of lymphocyte proliferation and interferon gamma and IL-4, so it considered good vaccine to control of Lumpy skin disease.

effect of zinc on humoral and cell-mediated immunity of broilers vaccinated against coccidiosis.
background: the aim of the present study was the comparison of humoral and cell-mediated immunity in broilers fed with different levels of zinc during a coccidiosis challenge. methods: one hundred and forty- four one-day-old broiler chicks were used with three dietary zinc (40, 120 and 200 mg/kg). at 14 d of age, all birds were inoculated orally with 5×10 3 sporulated oocysts of e. tenella . at...
متن کاملGenome of lumpy skin disease virus.
Lumpy skin disease virus (LSDV), a member of the capripoxvirus genus of the Poxviridae, is the etiologic agent of an important disease of cattle in Africa. Here we report the genomic sequence of LSDV. The 151-kbp LSDV genome consists of a central coding region bounded by identical 2.4 kbp-inverted terminal repeats and contains 156 putative genes. Comparison of LSDV with chordopoxviruses of othe...
متن کاملEVALUATION OF CELL-MEDIATED IMMUNITY IN MUSTARD GAS INJURIES
Yamakido, et al. in 1986 have studied immunological parameters in poison gas workers, and a depression has been observed in immunologic response. Also, the frequency of cancer has reached as high as five-fold that of the general population. In the present study, cell-mediated immunity (CMI) was measured in three groups of Iranian mustard gas-injured patients. The first group were those wh...
متن کاملHumoral and cell-mediated immunity to cytomegaloviruses.
Specific immunologic resistance mechanisms to cytomegalovirus (CMV) have not been extensively studied in either normal subjects or immunosuppressed renal allograft recipients. Such studies are in progress in my laboratory. Humoral immunity to CMV appears to be unimpaired in infected transplant patients. The neutralizing (NT) antibody titers in 24 allograft recipients with active CMV infection w...
