In bacteriology, 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 type of cell wall. The Gram stain is used by microbiologists to place bacteria into two main categories, Gram-positive (+) and Gram ...
Mobiluncus is a genus of Gram-positive, [2] anaerobic, rod-shaped bacteria.These bacteria may be stained either Gram-negative or Gram-variable. However, they are classified as Gram-positive rods due to the fact that they possess a Gram-positive cell wall, lack endotoxin and are sensitive to vancomycin, erythromycin and ampicillin, but resistant to colistin.
Arcanobacterium haemolyticum is a species of bacteria classified as a gram-positive bacillus. It is catalase-negative, facultative anaerobic, beta-hemolytic, and not motile. [1] It has been known to cause head and neck infections, pharyngitis, and sinusitis (Arcanobacterium haemolyticum infections). [1]
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 ...
Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores. [4] The major human pathogen in the genus is L. monocytogenes. Although L. monocytogenes has low infectivity, it is hardy and can grow in a refrigerator temperature of 4 °C (39.2 °F) up to the human body temperature of 37 °C (98.6 °F ...
Prevents bacterial cell division by inhibiting cell wall synthesis. Carbapenems; Ertapenem: Invanz: Bactericidal for both Gram-positive and Gram-negative organisms and therefore useful for empiric broad-spectrum antibacterial coverage. (Notes: MRSA resistance to this class. All are active against Pseudomonas aeruginosa except ertapenem.)
Corynebacterium (/ k ɔː ˈ r aɪ n ə b æ k ˌ t ɪər i ə m,-ˈ r ɪ n-/) is a genus of Gram-positive bacteria and most are aerobic.They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name (coryneform means "club-shaped").
Clostridium septicum is a large, gram-positive, rod-shaped bacterium that is a member of the normal gut flora in humans as well as other animals. [4] C. septicum are spore formers, with a terminal spore that gives them their drumstick-like shape. [5] They are also motile bacteria, using peritrichous flagellae to navigate from one environment to ...
