Bacteria in Swine Fever. âIn 1877 Klein published a research in a Report to the Local Government Board, in which he claimed to have discovered bacilli characteristic of the disease. They were described as similar to Bacillus subtilis, or Bacillus anthracis, but smaller in size. These bacilli developed into long leptothrix filaments, and formed spores. It was further asserted that on inoculation, cultures produced lesions indicative of swine fever ; the bacilli were also pathogenic in mice and rabbits. Later this bacillus was re- nounced in favour of another. In the following year Det- mers described a bacillus, but subsequently renounced it in favour of a micrococcus. In 1882 Pasteur maintained that the virus of swine fever in France (rouget) was a dumb-bell micrococcus, which produced the same effect in pigeons as the microbe of fowl-cholera. Though rouget or swine measles is probably a different disease, the occurrence of this micro-organism is of interest in this connection. In Klein again investigated swine fever, and discovered Bacillus No. 2, and maintained that these bacilli were found in â ^'â ^"'^ the blood, in the pieritoneal and ^ ^ ^ .="',,, ^ bronchial exudations ; and in the '* v.^ ==--.â . ^^ air vesicles of the lungs, in the '~^*' i== form of leptothrix filaments ten or twenty times the length of single rods. Cultivations were made on solid media. The organisms in these cultures were minute rods actively motile, occurring singly or formi
