Since Ehrlieh and Morgenroth (5) first published their famous horror autotoxicus concept hundreds of observations have been made supporting the idea that the formation of deleterious antibodies against an organism's own antigen is an exceptional event, if possible at all. Investigations on human ABO blood groups have furnished the best. known example of obedience to the biological principle of ...

The photodynamic action of dyes upon biological systems has been reviewed by Blum (1941). Inactivation of bacteriophage by this process has been studied by Clifton (1931), Perdrau and Todd (1933), Burnet (1933), Morales (1941), and Pacheco and Morales (1941). More recently, Welsh and Adams (1954) and Yamamoto (1956, 1958) investigated the kinetics of photodynamic inactivation of coliphage. In t...

Q fever has been described for the first time in 1935 as an outbreak of fever in workers of a slaughterhouse in Brisbane, Australia (Derrick, 1937). Derrick could not identify the aetiological agent therefore he defined the disease as “query fever”. Afterwards, in 1937, Burnet and Freeman (Burnet & Freeman, 1937) isolated a troublesome intracellular pathogen from mice inoculated with blood or f...
