Haemophilus aegyptius is characterized by which motility?

Explanation:
Motility type: Haemophilus aegyptius is nonmotile because it does not have flagella, the structures that would allow swimming. It appears as small Gram-negative coccobacilli and, in standard tests, shows no movement on wet mounts or in motility media. Twitching motility relies on surface pili, but Haemophilus aegyptius is not described as exhibiting this form of movement. So the best description is nonmotile.
