Haemorrhagic septicaemia (HS) is considered as a major and one of the most important infectious diseases of cattle and buffalo In some countries, particularly eastern Asian countries, animals play an important integrated role in rural communities as a main source of milk, fuel, meat and fertiliser HS due to P multocida serotype B, causes loss оддял of millions of dollars to the farming industry worldwide annually In order to control and minimise the losses, wide range of preventive measures, predominantly in vaccine development against HS has been carried out (Dabo et al , 2008) There have been several types of vaccines developed with very limited protection The clone ABA392 used in this study is derived from a P multocida serotype B 202, carrying a recombinant plasmid This clone was constructed by shotgun cloning method using E coli as host This recombinant plasmid harbours a sequence that code for a virulence factor to P multocida The aim of this study was to determine the immunogenicity of the clone, sub-cloning into an expression system and its potency as possible vaccine candidate.  Telepho2010 г Мягкая обложка, 200 стр ISBN 3639230191.
