    C. diphtheriae is a rod-shaped, Gram-positive, non spore-forming, and nonmotile bacterium. [17] C. diphtheriae has shown to exclusively infect humans. It is believed that humans may be the reservoir for this pathogen. However, there have been extremely rare cases in which C. diphtheriae has been found in animals. These infections were only ...

    The genera Corynebacterium [9] and Coccobacillus [10] have been designated as a pleomorphic genera, diphtheroid Bacilli have been classified as pleomorphic nosocomial bacteria. [11] Additionally, in one study focused on agents involved in a non-infectious disease, pleomorphic bacteria were found to exist in the blood of healthy human subjects. [12]

  5. Gram-positive bacteria - Wikipedia

    en.wikipedia.org/wiki/Gram-positive_bacteria

    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 ...
