Bacillus licheniformis is an interesting type of bacteria because it affects humans in many different ways. B. licheniformis is Gram-positive and rod-shaped. It is a motile bacterium, a facultative anaerobe (unlike other bacilli that are typically aerobic), and closely related to Bacillus subtilis.B. licheniformis produces endospores, and is usually found in the soil as spores.It is an apathogenic microorganism that is usually associated with plants and plant materials.t is a motile bacterium, a facultative anaerobe (unlike other bacilli that are typically aerobic), and closely related to Bacillus subtilis.

The genus Vibrio is comprised of many species of motile, aerobic Gram-negative rods that are found in aquatic environments. Three species are commonly pathogenic for humans, the most important being V. cholerae â the etiologic agent of epidemic cholera.he family Enterobacteriaceae is the largest and most heterogeneous collection of medically important gram-negative bacilli and are commonly isolated from clinical specimens. There are over fourteen genera that been described to cause human infection but by far the most important single species is Escherichia coli.
