Vaccines of pasteurellaceae mutants and vaccination method

Establishment of a Successive Markerless Mutation System in Haemophilus parasuis through Natural Transformation

Haemophilus parasuis, belonging to the family Pasteurellaceae, is the causative agent of Glässer's disease leading to serious economic losses. In this study, a successive markerless mutation system for H. parasuis using two sequential steps of natural transformation was developed. By the first homologous recombination, the target genes were replaced by a cassette carrying kanamycin resistance g...

Vaccination of rainbow trout against Streptococcus iniae infection: comparison of different routes of administration and different vaccines

Antibody production and clinical efficacy (relative percent survival RPS) were measured in 40±5g rainbow trout after immunization with two types of Streptococcus iniae vaccines consisting of formalin killed cells (FKC) and FKC enriched with the bacterial extracellular products (ECP) administered by intraperitoneal (i.p), immersion and oral routes at 16±1°C for 18 weeks. No significant differenc...

Evaluation of Cell-mediated Immune Response in PBMCs of Calves Vaccinated by Capri Pox Vaccines Using ELISA and Real-time RT-PCR

Background: The analysis of antigen-specific cytokine expression has been considered to evaluate the immune responses and vaccines efficacy in recent years. The aim of this study was to compare the cell-mediated immune response characteristics of two Capri pox virus (CaPV) vaccines against lumpy skin disease in cattle. Materials and Methods: Two Capri pox virus vaccines were administered to da...
