So far, EAR is the only processive antitermination system specific for Gram-positive bacteria. Further experiments failed to reconstitute EAR-mediated processive antitermination mechanism in vitro or in a Gram-negative heterologous host , suggesting that additional B. subtilis-specific factor(s) may also be required for EAR antitermination.
Rothia dentocariosa is a species of Gram-positive, round- to rod-shaped bacteria that is part of the normal community of microbes residing in the mouth and respiratory tract. [ 1 ] R. dentocariosa secretes a peptidoglycan hydrolase that inhibits the growth of Moraxella catarrhalis (an ear infection pathogen) in vitro, indicating that it may ...
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...
Auritidibacter ignavus is a Gram-positive, aerobic, non-spore-forming and rod-shaped species of bacteria from the family Micrococcaceae which has been isolated from an ear swab in Bad Orb, Germany. [1] [2] [3] [4]
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane. Specific to gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of these are lipoteichoic acids, which have a lipid component in the cell membrane that can assist ...
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
C. pseudotuberculosis is a Gram-positive bacterium that has been observed as coccoid or filamentous rods, which can be organized into palisades.Metachromatic volutin granules containing phosphate can be seen in the rod form. but not in the coccoid form when stained using Albert's or Neisser's methods.
