Otto Guilherme Bier

Otto Guilherme Bier, Brazilian bacteriologist and immunologist (Rio de Janeiro 26 March 1906 - São Paulo 22 November 1985)
From German descent
Authored over 100 works
Performed important contributions on studies of antigen-antibody reactions and complement system

With M. Siqueira found that antigen-antibody complexes can act even at the site of passive cutaneous anaphylaxis reactions evoked by unrelated antigen-antibody systems

Hemorrhagic reactions at sites of passive cutaneous anaphylaxis in guinea pig after intravenous inoculation of unrelated immune complex. Proceed. Soc. Exper. Biol. Med. 107(4):779-84, 1961  

With M. Siqueira & G. Biozzi observed that immunological competence develops eventually, even in bursectomized animals, albeit with a considerable delay in time 


Codescribed Pacheco disease in Psittacidade birds (1929)

Pacheco, G., Bier, O. Epizootie chex lês perroquets du Brésil. Relations avec Le psittacose. C.R. Séance Soc. Biol. 105:109-111, 1930.

Showed that Bothrops venom displayed inactivant action on fourth component of complement system

Uber Komplement-inativierung durch Bothropsgift (B. jararaca). Zeitschr. F. Immunit. 11:187-94, 1932 

With M. Rocha e Silva noticed that the hemolysis is inhibited by hypertonic concentrations of NaCl (1935)


Described serovar Salmonella butantan with Amaral, Peluffo & Biocca 1946

Described the biological role of antibodies on glomerulonephritis
