Delayed-type hypersensitivity to rabies virus in mice: assay of active or passive sensitization by the footpad test.

abstract：:The virulence of Neisseria gonorrhoeae for chicken embryos can be modified in a predictable manner by the addition of microbial siderophores to the inoculum. "Meningobactin" and "gonobactin," siderophores isolated from iron-limited cultures of meningococci and gonococci, respectively, enhance the virulence of the rela...
