Epithet Epitaphs, Ernest L. Biberstien

The prokaryotic genus Bibersteinia is named after bacteriologist Ernest L. Biberstien. Biberstein did much of the early characterization of the species Bibersteinia trehalosi originally classified [Pasteurella] trehalosi. The species is a pathogen associated with pneumonia in sheep and systematic infections in lambs. The genus of this species is derivative of Biberstein’s last name, and the species name contains the Latin root hal- which can mean breath, most likely referring to its association with pneumonia in sheep. The discovery was made due to advancements in pathogenesis and epidemiology of the organism that allowed for a reclassification of the collection of strains identified as genus Pasteurella.   Biberstein characterized the serotyping scheme for the organism; sterotypes are district variations within a species of cell surface antigens. He also preformed some of the earliest DNA-DNA relatedness studies that indicated the unique nature of the taxon.
