Bibersteinia trehalosi
Bibersteinia trehalosi is a Gram-negative bacterium in the Pasteurellaceae family. It was first named Pasteurella trehalosi in 1990 and was moved to the new genus Bibersteinia in 2007 after genetic and biochemical studies. The genus name honors German veterinarian Ernst Ludwig Biberstein, and the species name trehalosi comes from its ability to ferment the sugar trehalose.
On blood agar, the bacteria form small, greyish, smooth colonies that are non-hemolytic or only weakly hemolytic. Bibersteinia trehalosi mainly affects ruminants, especially sheep and cattle, causing respiratory and sometimes systemic diseases. It is a common cause of pneumonia, septicemia, and sudden death in lambs and calves. Because it can trigger outbreaks in livestock, this bacterium is an important concern in veterinary microbiology and livestock health management.
