Borrelia Caucasica
''Borrelia'' is a genus of bacteria of the spirochete phylum. Several species cause Lyme disease, also called Lyme borreliosis, a zoonotic, vector-borne disease transmitted by ticks. Other species of ''Borrelia'' cause relapsing fever, and are transmitted by ticks or lice, depending on the species of bacteria. The genus is named after French biologist Amédée Borrel (1867–1936), who first documented the distinction between a species of ''Borrelia anserina'' and the other known type of spirochete at the time, ''Treponema pallidum''. This bacterium must be viewed using dark-field microscopy, which make the cells appear white against a dark background. ''Borrelia'' species are grown in Barbour-Stoenner-Kelly medium. Of 52 known species of ''Borrelia'', 20 are members of the Lyme disease group (with an additional 3 proposed), 29 belong to the relapsing fever group, and two are members of a genetically distinct third group typically found in reptiles.

Lyme Disease
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of ''Borrelia'' bacteria, Disease vector, transmitted by blood-feeding ticks in the genus ''Ixodes''. It is the most common disease spread by ticks in the Northern Hemisphere. Infections are most common in the spring and early summer. The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. The rash is typically neither itchy nor painful. Approximately 70–80% of infected people develop a rash. Other early symptoms may include fever, headaches and fatigue (medical), tiredness. If untreated, symptoms may include Facial nerve paralysis, loss of the ability to move one or both sides of the face, arthritis, joint pains, Meningitis, severe headaches with neck stiffness or heart palpitations. Months to years later, repeated episodes of joint pain and swelling may occur. Occasionally, shootin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endoflagella
A spirochaete () or spirochete is a member of the phylum Spirochaetota (also called Spirochaetes ), which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled (corkscrew-shaped or spiraled, hence the name) cells. Spirochaetes are chemoheterotrophic in nature, with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm. Spirochaetes are distinguished from other bacterial phyla by the location of their flagella, called endoflagella, or periplasmic flagella, which are sometimes called ''axial filaments''. Endoflagella are anchored at each end (pole) of the bacterium within the periplasmic space (between the inner and outer membranes) where they project backwards to extend the length of the cell. These cause a twisting motion which allows the spirochaete to move. When reproducing, a spirochaete will undergo asexual transverse binary fission. Most spirochaetes are free-living and anaerobi ...

Borrelia Mayonii
''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. Phylogenetic information ''Borrelia mayonii'' was identified as a ''sensu lato'' (broad sense), genospecies (Bbsl) of the known microbe, '' Borrelia burgdorferi''. A genospecies is a cluster of organisms with similar core genes that usually does not undergo genetic recombination with diverged organisms. Two isolates, gene strains, of ''B. mayonii'', named MN14-1420 and MN14-1539, were sequenced, process of arranging a chain of genetic information to match up to a specific organism's genetic code, and compared to the genome or genetic material of ''Borrelia burgdorferi''. With a nucleotide similarity of 93.83% in the linear chromosome compared to other known genospecies, ''B. mayonii'' can be considered a new genospecies (Bbsl). Discovery ''Borrelia mayonii'' i ...

Borrelia Afzelii
''Borrelia afzelii'' is a species of ''Borrelia'' endemic to parts of Eurasia where it is one of the causative agents of Lyme disease. It is transmitted by hard-bodied ticks of the Ixodes genus (''Ixodes ricinus'' in Europe, and '' Ixodes persulcatus'' in temperate regions of Asia), infecting various wild mammals in nature. Among 30 ''Borrelia'' known species, it is one of four which are likely to infect humans. Dermatological manifestations are more common in Lyme disease caused by ''B. afzelii''. It is named after Swedish dermatologist Arvid Afzelius.

Borrelia Miyamotoi
''Borrelia miyamotoi'' is a bacterium of the spirochete phylum in the genus ''Borrelia''. A zoonotic organism, ''B. miyamotoi'' can infect humans through the bite of several species of hard-shell ''Ixodes'' ticks, the same kind of ticks that spread ''B. burgdorferi'', the causative bacterium of Lyme disease. Ixodes ticks are also the primary vector in the spread of babesiosis and anaplasmosis. ''B. miyamotoi'' causes ''Borrelia miyamotoi'' disease (BMD) in humans. BMD is a relapsing fever illness that has been reported across the world, often in the same geographic areas where Lyme disease is endemic. Treatment currently follows that of Lyme disease. Microbiology History and morphology ''B. miyamotoi'' was discovered in 1995 when it was isolated from a population of '' Ixodes persulcates'' ticks on the Japanese island of Hokkaido. The organism was named for Kenji Miyamoto, who initially discovered ''Borrellia'' spirochetes in Japan. It was first detected in the United State ...

Genome Taxonomy Database
The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to resolving paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, updating names in both cases. Information for archaea was added in 2020, along with a species classification based on average nucleotide identity. Each update incorporates new genomes as well as automated and manual curation of the taxonomy. An open-source tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy. The GTDB system, via GTDB-Tk, has been used to catalogue not-yet-named bacteria in the human gut microbiome and other metagenomic sources. The GTDB is incorporated into the '' Bergey's Manual of Systematics of Archaea and Bacteria'' in 2019 as its phylogenomic resource. Methodology The genomes used to construct the phyloge ...
