Flowchart for identifying aerobic Gram-negative rods or Gram-negative coccobacilli.

3.4.6 Gram-negative, aerobic cocci and rods (e.g., Acetobacter) Negative bacteria, aerobic cocci as well as rods help compensate about 20% of the bacteria inside the digester (Rincón-Llorente et al., 2018). They help with microbial phosphorus removal, soluble cBOD decay, floc production, and nitrification, among other things.

This flowchart summarizes the steps to identify aerobic Gram negative rods based on biochemical tests and growth characteristics. It shows that identification begins with determining if the organism is Gram negative and grows on MacConkey agar.

Clinically significant Gram-negative bacteria are usually rods, as shown near bottom right. Although some gram-negative bacteria can be recognized by "bench tests", diagnosis in the modern microbiology lab usually involves MALDI-TOF and/or multitarget assay.

Gram-negative aerobic bacteria are the most common cause of spontaneous bacterial peritonitis, followed by gram-positive cocci. Bacterial translocation from the intestine and an altered host immune response are thought to be responsible for the development of spontaneous bacterial peritonitis Mowat and Stanley (2001) .

2012年6月1日 · Gram-negative bacteria may be rod-shaped (bacilli), spherical (cocci), oval, helical, or filamentous. Cytoplasmic membrane is surrounded by a cell wall consisting of a peptidoglycan layer and an outer cell membrane. Gram-negative bacteria are widely distributed in the natural environment.

This flowchart provides guidance for identifying aerobic Gram-negative rods based on results of gram stain, growth on MacConkey agar and lactose fermentation, and biochemical test results including indole, oxidase, urease and motility.

Neisseria meningitidis are Gram-negative aerobic bacteria, commonly known as meningococci and are exclusively human pathogens causing meningitis. The major virulence factor is the K-antigen: on the basis of its structure, twelve different K-types were identified (A, B, C, H, I, K, L, X, Y, Z, 29E and W135) ( Griffiths and Davies, 1991b ).
