An automated image analysis method has been developed for the monitoring of the Gram-staining characteristics of filamentous bacteria in activated sludge. The binary method of pixel classification agreed with manual estimation (level of correlation of 0.9 for Gram-positive bacteria). Its robustness has...

Gram Staining Gram staining is used to evaluate a body fluid or specimen for the presence of microorganisms (Figure 5-41). Organisms are classified according to their gram-positive or gram-negative color characteristics, morphology (e.g., coccus, rod), and other features (e.g., chain or cl...
Characteristics of Gram Positive BacteriaCell WallThe cell-wall of Gram positive bacteria consists of a number of important components that include:PeptidoglycanLocated outside the cytoplasmic membrane of most bacteria, the peptidoglycan is one of the main components of the bacterial cell wall. For ...
What is the difference between positive and negative Gram staining? The difference between gram positive and gram negative staining is that gram positive bacteria stain purple, due to attachment of the crystal violet dye to the thick layer of peptidoglycan in the cell wall. Gram negative bacteria ...
Genus: Streptococcus: Characteristics of this group of bacteria are discussed below in detail.Some examples of Streptococcius bacteria include:Streptococcus pneumoniae Streptococcus mutans Streptococcus bovis Streptococcus salivarius Streptococcus oralis Streptococcus canis...
(between gram-positive or gram-negative bacteria) was causing a type of pneumonia in humans. The staining technique he developed was used to differentiate between gram-positive and gram-negativebacterial cell wallsand the presence of peptidoglycan within. The bacteria are placed on a slide and ...

Microbiologists currently recognize two distinct groups of gram-positive, or weakly staining gram-positive, prokaryotes. The class Actinobacteria comprises the high G+C gram-positive bacteria, which have more than 50% guanine and cytosine nucleotides in their DNA. The class Bacilli comprises low G+...
Molecular determination of the Gram stain characteristics of bacteria that cause orthopedic infections may be achieved, in most instances, by this method. Further studies are necessary to understand the clinical importance of PCR-positive/culture-negative results. 2006 Orthopaedic Research Society. ...
