The first step in isolating the bacteria is to streak for individual colonies. Next, a microbiologist will examine the visible appearance, or , of the isolated colonies in order to try and recognize different species. Some bacterial colonies are visually very different. Microbiologists use a ...
A bacterial colony can be identified by the morphology of the colony. Different types of bacteria give rise to colonies that look different. Some of the bacterial colonies are colored, some are circular in shape, and a few others are irregular. The shape, size, and pigmentation of the coloni...

Advances in microscopy hold great promise for allowing quantitative and precise measurement of morphological and molecular phenomena at the single-cell level in bacteria; however, the potential of this approach is ultimately limited by the availability of methods to faithfully segment cells independent of...
In this book, we use the term spore discharge to refer to the separation of fungal spores from their parent colonies and fruit bodies, and spore dispersal for their subsequent movement. Discharge often launches spores over a short distance, whereas dispersal can involve travel over vast distances...
The identity of the receptors driving this recognition is not yet clear, but it has been shown that, much like it binds to the LPS of bacteria, TLR4 can recognize and bind to the polysaccharide glucuronoxylomannan (GXM) present in the capsule of C. neoformans. In addition, in one model...
Molecular characterization of Brucella strains isolated from marine mammals Recently, gram-negative bacteria isolated from a variety of marine mammals have been identified as Brucella species by conventional phenotypic analysis.

Viable bacteria,with tiny colonies formed on the LA agar plates,remained at about 103cfu·m L- 1after 500 d starvation. Under SEM a large portion of cells changed from short rod shape to coccus shape,and a small portion of cells displayed long rod shape or produced flocs.The results of ...
However, they can also originate from a distant source of infection [28]. The initial adhesion of bacteria to the surface is a reversible process, but when biochemical interactions between the surface of the material and the bacteria start to act, the process becomes irreversible. In these ...
Indeed one of the fundamental distinctions between different types of bacteria is made on the basis of the wall structure. The Gram stain functions to distinguish between these marked differences in structure. Figure 3 shows a comparison of the cell structures of Gram-positive and Gram-negative ...
