Gram Positive bacteria and their disease Flashcards Quizlet. Streptococci. Streptococci are spherical bacteria that divide in parallel planes to produce chains. The bacteria are Gram‐positive, and certain species are aerobic, while others are anaerobic. On blood agar, certain species partly destroy the red blood cells and are said to be alpha‐hemolytic, Bacteria may contain enzymes that inactivate the antibiotic. Examples of such enzymes include β-lactamase- and aminoglycoside-modifying enzymes. β-lactamases are common mechanisms of resistance in both gram-positive and gram-negative bacteria. β-lactamases hydrolyze the β-lactam ring and render it ineffective..

In recent years, a group of antibacterial proteins produced by gram-positive bacteria have attracted great interest in their potential use as food preservatives and as antibacterial agents to combat certain infections due to gram-positive pathogenic bacteria. Gram-positive bacteria have a cell wall composed of multiple layers of peptidoglycan that forms a rigid and thick structure. Its cell wall additionally has teichoic acids and phosphate. The teichoic acids present in the gram-positive bacteria are of two types – the lipoteichoic acid and the teichoic wall acid. The cell wall is known as murein.

Oct 15, 2018В В· 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 Gram, identifies bacteria based upon the reaction of their cell walls to certain dyes and chemicals. Gram-positive bacteria do not contain LPS, yet they trigger a toxic shock syndrome similar to that induced by LPS. This response is caused by cell wall components of Gram-positive bacteria, such as peptidoglycan (PGN) and LTA (Fig. 4).PGN is an alternating ОІ(1, 4) linked N-acetylmuramyl and N-acetylglucosaminyl glycan whose residues are crosslinked by a short peptide.

commonly a contaminant. For example, if one set is ordered and is positive for coagulase-negative staphylococci, a common contaminant, it is impossible to determine if this represents contamination or infection. However, if two sets are ordered, and only one is positive for coagulase-negative staphylcocci, this most likely represents contamination. Gram-positive bacteria are classified into high G+C gram-positive and low G+C gram-positive bacteria, based on the prevalence of guanine and cytosine nucleotides in their genome; Actinobacteria is the taxonomic name of the class of high G+C gram-positive bacteria.

Six gram-positive genera of bacteria are known to cause disease in humans: Streptococcus, Staphylococcus, Corynebacterium, Listeria, Bacillus and Clostridium. Another 3 cause diseases in plants: Rathybacter, Leifsonia, and Clavibacter. Gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their cell wall.. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope.
