It is now possible to differentiate pathogenic and non-pathogenic strains of the bacteria Haemophilus parasuis without challenging animals

A genomic study has demonstrated that pathogenic strains of Haemophilus parasuis (H. parasuis) display a type of proteins which allows the bacteria to adhere to tissues and quickly disseminate in the organism. From this discovery, a simple molecular assay was designed for distinguishing possible pathogenic strains of this bacteria and therefore to develop future vaccines.
