Moraxella lacunata is a rod-shaped, [1] Gram-negative, nonmotile bacterium, generally present as diploid pairs. [2] It causes one of the commonest forms of catarrhal conjunctivitis. [3]
Moraxella lacunata was first described independently by Victor Morax (1896) and Theodor Axenfeld (1897), hence the alternate name "Morax-Axenfeld diplobacilli" and the name of eye infection in humans is sometimes called Morax-Axenfeld conjunctivitis. [2]
It has the ability to change its morphology in laboratory. M. lacunata became shorter and tended to lose its Gram-negative staining characteristic when left out for 5 days. It also tended to retain these new characteristics on subsequent blood-agar transfers. [4]
Infection occurs mainly in adults, but can occur at any age. It is characterized by:
