Borrelia burgdorferi is a microaerophile, requiring small amounts of oxygen in order to undergo glycolysis and survive. Like all other Borrelia sps., this bacterium is also gram-negative and a spirochete. Borrelia colonies are often smaller, rounded, and white with an elevated center. [7] B. burgdorferi possesses flagella that allow it motility.
Borrelia species have an outer membrane that contains a substance similar to lipopolysaccharides, an inner membrane, and a layer of peptidoglycan in a periplasmic space, which classifies them as Gram-negative. [5] However, this result is not easily visualized using Gram staining. [5] They are typically 20–30 μm long and 0.2–0.3 μm wide. [5]
B. burgdorferi is a highly specialized, motile, two-membrane, flat-waved spirochete, ranging from about 9 to 32 micrometers (μm) in length. [44] Because of its double-membrane envelope, it is often mistakenly described as Gram negative, [45] though it stains weakly in Gram stain.
Lyme disease is caused by spirochetes, gram-negative bacteria from the genus Borrelia. Spirochetes are surrounded by peptidoglycan and flagella . [ 57 ] The Lyme-related Borrelia species are collectively known as Borrelia burgdorferi sensu lato , and show a great deal of genetic diversity .
Gram-negative bacteria stain as pink in the Gram stain. ... (e.g. Borrelia burgdorferi). Usually, a single bacterial chromosome is present, although some species with ...
Owing to their morphological properties, spirochetes are difficult to Gram-stain but may be visualized using dark field microscopy or Warthin–Starry stain. [35] Examples include: Leptospira species, which cause leptospirosis. Borrelia species, such as Borrelia burgdorferi, a tick-borne bacterium that causes Lyme disease
Borrelia mayonii is a Gram-negative, host-associated spirochete that is capable of causing Lyme disease. This organism can infect various vertebrate hosts such as humans via the bite of a black legged tick .
"Borrelia burgdorferi is gram negative only by default because safranin is the last dye used, but in reality spirochetes are not classified as either gram positive or negative." This sentence starts with too much detail for an encyclopedia, and ends by indicating that the sentence itself is irrelevant to the article.
