Action of bacterial toxins on tumors. VI. Protection against 

 tumor hemorrhage following heterologous immunization 



Proc. Soc. Exper. Biol. & Med. I87-I89, 19^3 



Heterologous immunization was as effective as homologous in 

 the protection against induction of tumor hemorrhage. A common 

 antigenic toxic component may characterize all gram-negative 

 bacteria.

Sobre uma posslvel rela^aS' entre a acaS* pirogenica e urn feno-

 possible relation between pyrogenic activity and the phenomenon 

 of gelification presented by various bacteria) 



Arq. biole (Aso Paulo) 28:36-39, 1944 



Pyrogen formation is found to closely parallel the presence 

 of colon bacteria of the Salmonella -Shigella - Proteus groups, 

 S.. hemophilus . Brucella and vibrios of threadlike structures. 

 These threads appear during growth of the organisms in 3 per 

 cent KOH, The phenomena has a close relationship to gelation. 

 The possibility exists that nucleinic acid may play a part 

 in the fibril development; similarities to the agglutination 

 of red cells are noted.

Detection of pyrogens in fluids by biological methods 



Indian J. Med. Res. 32:9-14, 1944 



Hyperpyrexia as an index for the presence of pyrogens in water 

 gives only moderately satisfactory results; the leucopenia 

 index is still less accurate. In this series, distilled water 

 and reservoir waters were compared for the presence of pyrogens. 

 Care in handling of test rabbits was observed in this study. 

 The accuracy of rectal temperature readings depended upon the 

 position of the thermometer during reading. In the normal 

 rabbit, allowances of 0,6° C. in temperature were made. Only 

 slight temperature changes were noted after the injection of
