[2]: 518 The microbiologist examines the appearance of the colony, noting specific features such as size, colour, shape, consistency, and opacity. [1]: 165–8 A hand lens or magnifying glass may be used to view colonies in greater detail. [3]: 96 The opacity of a microbial colony can be described as transparent, translucent, or opaque.
The formation of patterns in the growth of bacterial colonies has extensively been studied experimentally. Resulting morphologies appear to depend on the growth conditions. They include well known morphologies such as dense branched morphology (DBM) or diffusion-limited aggregation (DLA), but much complex patterns and temporal behaviour can be fou

Haemophilus ducreyi is a Gram-negative coccobacillus, and has a shape between a spherical coccus [6] and a rod-shaped bacterium. [1] This species of bacterium has pili, fine and tangled appendages composed predominantly of protein, that allow bacteria to attach to surfaces, including those of cells.
Colony characteristics Large, eugonic, buff coloured and rough colonies ( Löwenstein-Jensen medium at 30 °C). Cauliflower-like morphology, resembling M. tuberculosis colonies.
Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. [2]
The morphology is quite variable and seems to depend, in part, on the age of the culture as the smallest form observed, coming from the elementary body, is 80nm to 100nm wide in diameter. [13] Different cell forms have been observed varying from coccoid cells to filaments and irregularly shaped structures with coccoid forms and ring- or disc ...
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens.
