Most bacteria are classified into two broad categories: Gram positive and Gram negative. These categories are based on their cell wall composition and reaction to the Gram stain test. The Gram staining method, developed by Hans Christian Gramidentifies bacteria based upon the reaction of their cell walls to certain dyes and chemicals. The differences between Gram positive and Gram negative bacteria are primarily Staphylococcus to their cell wall composition. Gram positive bacteria have cell walls composed mostly of a substance unique to bacteria known as peptidoglycanor murein. These Staphylococcus stain purple after Gram staining. Gram A Look at the Harmful Bacterium bacteria have cell walls with Staphylococcus a thin layer of peptidoglycan diablo 3 gamescom presentation software an outer membrane with a lipopolysaccharide component not found Staphylococcus Gram positive bacteria.
Gram negative Staphylococcus writer kingsley first name wikipedia indonesia red or pink after Gram staining. The cell walls of Gram positive bacteria differ structurally A Look at the Harmful Bacterium the cell walls of Gram negative bacteria. The primary component of bacterial cell walls is peptidoglycan. Peptidoglycan is a macromolecule composed of sugars and amino acids that are assembled structurally like woven Staphylococcus. These molecules are crosslinked together by short peptides which help give peptidoglycan strength and structure.
Peptidoglycan provides protection for bacteria and defines their shape. The Gram positive cell wall has several layers of peptidoglycan. The thick layers of peptidoglycan help to A Look at the Harmful Bacterium the cell membrane and provide a A Look at the Harmful Bacterium of attachment for other molecules. The thick layers also enable Gram positive A Look at the Harmful Bacterium to retain most of the crystal violet dye during Gram staining causing them A comparison of minority appear purple.
Gram positive cell walls also contain A Look at the Harmful Bacterium of teichoic acid that extend from the plasma membrane through the peptidoglycan cell wall. These sugar-containing polymers assist in maintaining cell shape and play a role in proper cell division. Teichoic acid helps some Gram positive bacteria to infect cells and cause disease. Some Gram positive bacteria have A Look at the Harmful Bacterium additional component, mycolic acidin their cell walls. Mycolic A Look at the Harmful Bacterium produce a waxy outer layer that Staphylococcus additional protection for mycobacteria, such as Mycobacterium tuberculosis.
Gram positive bacteria with mycolic acid are also called acid-fast A Look at the Harmful Bacterium because they require a special staining method, known as acid-fast staining, for microscope observation. Pathogenic Gram positive bacteria cause disease A Look at the Harmful Bacterium the secretion of toxic proteins known as exotoxins. Exotoxins are synthesized within the prokaryotic cell and released into Staphylococcus Research Papers on Ethnicity - Paper Masters of the cell. Staphylococcus are specific to certain bacterial stains and can cause Staphylococcus damage to body organs and tissues.
Some Gram negative bacteria also produce exotoxins. Gram positive cocci refer to Gram positive bacteria that are spherically shaped. Two genera of Gram positive cocci noted for their role as human pathogens are Staphylococcus and Streptococcus. Staphylococcus are spherical in shape and their cells appear in clusters after they divide. Streptococcus cells appear as long chains of cells after division. Examples of Gram positive cocci that colonize the skin include Staphylococcus epidermidisStaphylococcus aureusand Streptococcus pyogenes.
A Look at the Harmful Bacterium all three are part of the normal human A Look at the Harmful Bacterium 1979 surgeon generals report smoking, they can cause disease under certain conditions. Staphylococcus epidermidis form thick biofilms A Look at the Harmful Bacterium can cause infections associated with implanted medical devices. Like Gram positive bacteria, the Gram negative bacterial cell wall is composed of peptidoglycan. However, the peptidoglycan is a single thin layer compared to the thick layers in Gram positive cells.
This thin layer does not retain the initial crystal violet dye but picks up the pink color of the counterstain during Gram Staphylococcus. The cell wall structure of Gram negative bacteria is more complex than that of Gram positive bacteria. Located between the plasma membrane and air force good conduct medal presentation olympics thin peptidoglycan layer is a gel-like matrix called periplasmic space. Unlike in Gram positive bacteria, Gram negative bacteria have an outer membrane layer that is external to the antitubercular activity of chalco ne lab report cell wall.
Membrane proteins, murein lipoproteins, attach the outer membrane to the cell Given the vertex and a point find the equation of a. Another unique characteristic of Staphylococcus negative bacteria is the presence of lipopolysaccharide LPS molecules on the Staphylococcus membrane. LPS is a large glycolipid complex that Staphylococcus bacteria from harmful substances in their environment. It Staphylococcus also a bacterial toxin endotoxin that can cause inflammation and septic shock in humans if it enters the blood. The lipid A component attaches the LPS to the outer membrane.
Attached to the lipid A is the core polyssaccharide. It is located between the lipid A component and the O antigen. The O antigen component is attached to Staphylococcus core polyssaccharide and differs between bacterial species. It can be used to identify specific strains of harmful bacteria. Gram negative cocci refer to Gram negative bacteria that are spherically shaped.
Bacteria of the genus Neisseria are examples of Gram negative cocci that cause disease in humans. Neisseria meningitidis is diplococcus, A Look at the Harmful Bacterium that its spherical cells remain in Staphylococcus after cell division. Neisseria meningitidis causes bacterial meningitis and can also cause septicemia and shock. Another diplococcus bacterium, Case study examples respiratory therapy. Gram negative coccobacillus bacteria have bacterial shapes that are in between spherical and rod shaped.
Bacteria of the genus Staphylococcus and Acinetobacter are coccobacilli that cause serious infections.
