Dopter in 1911 distinguished as parameningococcus one strain, which now becomes one of the types. In brief, Gordons Type I stands at one end of a series. His Type IV, which corresponds with Dopters parameningococcus, at the other end. Types II and III occupy places between in the series, but there are many other strains which are intermediate. Indeed, more than fifty different subtypes have been distinguished approaching more or less closely in their agglutinative characters one or other of these main types. It is stated in this form because there is, even with this most accurate method of recognizing a specific organism, a certain amount of cross agglutination, so that it is only an organism which gives the maximum reaction with a serum produced by the arbitrary original Type I and the minimum reaction with the serum of Type IV that is classed with Type I. Doubtless with further study other differences may be found, as in the case of the Pfeiffer bacillus, which will make this differentiation more stable. No very sharp distinction can be made between these types as far as concerns their virulence and ability to produce disease. It is true, however, that there is a great difference in the susceptibility of individuals, since many become the healthy carriers of one or other type, probably through mere contact with infected persons. Others after surviving the disease remain as carriers of the organisms which are lodged in the nasopharynx. It was the problem of the recognition and disposition of such carriers which at first occupied so much attention in the various armies. As to the mode of infection, there is little doubt that transmission is by way of organisms which pass from the nas. . . This item ships from La Vergne,TN.<
