ACHIEVEMENTS
Demonstrated that agar and other carbohydrates can be antigens and stimulate precipitins

Demonstrated that heteroantigen is composed of two parts (lipid and protein), a concept later retrieved by Landsteiner  (1918-25)

Demonstrated existence of a specific lipoid that fixates antibodies on heterogenetic antigen

His preparation and titration methods of bacterial toxins were adopted worldwide 

Established titration methods of anti-diphtheria, anti-dysentery, anti-gangrene, anti-ophidic and other sera  

Elaborated and perfected economic and rapid immunization for obtaining sera of high efficiency  

Developed a technique for obtaining anti-diphtheria serum was later adopted by J. Bordet  and perfected by Ramon  

With A. Manzullo developed a method for diagnose of diphtheria

With Soriano, Ferrari & Torino described Clostridium saprotoxicum 1934 

Discovered  Clostridium sordellii, causative agent of gas gangrene  (1922)
 

Created a method for measuring minute tensions

With R. Wernicke. Um metodo de medida de pequeñas tensiones. Anal. Asoc. Quim. Arg. 1:8, 1913
