What does this bacterium look like?   

Actinobacillus is a small rod that occurs mainly alone or aggregated in pairs. This bacterium has a thin cell wall and is between 1 and 2 micrometers in size. This is very small when you know that 1,000 micrometers fit into one millimeter.


What does science already know about this bacterium

Actinobacillus was first described in 1902 by Lingnières and Spitz during a study in animals. They named this organism Actinobacillus lingnieresii. In livestock, this genus of bacteria plays a major role in the outbreak of infections so it is still the subject of much research in veterinary medicine. In humans, this genus Actinobacillus is found almost everywhere in the body and the presence of this bacterium is generally quite harmless.
