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 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 ...
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 .
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 lusitaniae is a bacterium of the spirochete class of the genus Borrelia, which has a diderm (double-membrane) envelope. [1] It is a part of the Borrelia burgdorferi sensu lato genospecies [2] and is a Gram-negative bacterium. B. lusitaniae is tick-borne; he type strain is PotiB2. [1] It can be pathogenic, being involved in cases of ...
