ConclusionsThe ability of sulfanilamide and structurally related compounds to develop color on ultraviolet irradiation appears to be dependent on the presence or absence of substituents in the p-amino and sulfamido groups. A study of the anticatalase

SummaryP-Caproylaminobenzenesulfonhydroxamide produces bacteriostasis of pneumococci in blood without the lag characteristic of sulfanilamide. The activity is only about one-eighth of the corresponding bacteriostatic power in broth. That the immediat

Résumé A rabbit immunized by a culture of killed B. subtilis spores develops almost an equal amount of agglutinins for both spores and bacilli, unless the disorganized remnants of the latter are removed from the antigen. A rabbit immunized with a c

Introduction. This study purports to make inquiry into the physico-chemical nature and methods of combating the marked cohesion exhibited by many bacteria. As the studies of Northrup and DeKruif (1) have shown, cohesion plays an important part in the

In one of the sulfones is to be found the first chemotherapeutic agent against tuberculosis that has sufficient promise experimentally to justify a thorough-going trial clinically. As regards the difficult problem concerning the mode of action of the

Summary1. Reduction of the percentage of oxygen in the superambient air of broth cultures of the Type I pneumococcus greatly reduced or prevented bacteriostasis by sulfanilamide.2. When the oxygen concentration was reduced to 0.04% an actual stimulus

Conclusion1. In a series of 118 cases of general hemolytic strep tococcal infectims a mortality of but 12% has attended the administration of antisera prepared from 2 anomalous dissociants of a cellulitic strain of hemolytic streptococcus. 2. The obj

The experiments to be reported here have been designed to overcome the last remaining obstacles to the acceptance of the view that the acidfast group of bacteria possess a filtrable phase in their life history. The matter is stated in this way becaus
