Davaine, Casimir-Joseph

In 1850, Pierre-Francoise OHve Rayer (Rayer, 1850) and Casimir-Joseph Davaine (Davaine, 1863) reported the presence of small filiform bodies in the blood of anthrax-infected sheep (Carter, 1988). By 1855, Franz Aloys Antoine PoUender confirmed this discovery and impheated their role in producing anthrax disease (PoUender, 1855). In 1858, Freidrich August Brauell noted the bodies to be absent from healthy animals or animals infected with diseases other than anthrax. Brauell also noted their inability to be transmitted from pregnant sheep to fetus (Brauell, 1857).
