Campylobacter jejuni is a species of pathogenic bacteria that is commonly associated with poultry, and is also often found in animal feces. This species of microbe is one of the most common causes of food poisoning in Europe and in the US, with the vast majority of cases occurring as isolated events rather than mass outbreaks.
Campylobacter is a type of bacteria that can cause a diarrheal disease in people. [1] Its name means "curved bacteria", as the germ typically appears in a comma or "s" shape. According to its scientific classification, it is a genus of gram-negative bacteria that is motil
C jejuni appears to achieve this by invading and destroying epithelial cells. [citation needed] C. jejuni can also cause a latent autoimmune effect on the nerves of the legs, which is usually seen several weeks after a surgical procedure of the abdomen. The effect is known as an acute idiopathic demyelinating polyneuropathy (AIDP), i.e ...
Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]
The Gram-negative diplococci Neisseria and Moraxella are oxidase-positive. [2] Many Gram-negative, spiral curved rods are also oxidase-positive, which includes Helicobacter pylori, Vibrio cholerae, and Campylobacter jejuni.
Campylobacter upsaliensis shares the characteristic appearance of other Campylobacter species: it is a curved to spiral, gram-negative rod that displays darting motility. [ 2 ] [ 7 ] The bacterium either have one polar flagellum , or two flagella with one at either end, and can range from 0.2μm to 0.5μm in width and 0.5μm to 8μm in length.
Both gram-positive and gram-negative bacteria commonly have a surface layer called an S-layer. 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 ...
Campylobacter jejuni is a common pathogen of bacterial food-related gastrointestinal illness. A spirillum (plural spirilla) is a rigid spiral bacterium that is gram-negative and frequently has external amphitrichous or lophotrichous flagella. [33] Examples include: Members of the genus Spirillum
