Borrelia
''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. A few ''Borrelia'' species as ''Candidatus'' Borrelia mahuryensis harbor intermediate genetic features between Lyme disease and relapsing fever ''Borrelia''. The genus is named after French biologist Amédée Borrel (1867–1936), who first documented the distinction between a species of ''Borrelia'', ''B. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lyme Disease
Lyme disease, also known as Lyme borreliosis, is a vector-borne disease caused by the '' Borrelia'' bacterium, which is spread by ticks in the genus '' Ixodes''. 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. Early diagnosis can be difficult. Other early symptoms may include fever, headaches and tiredness. If untreated, symptoms may include loss of the ability to move one or both sides of the face, joint pains, severe headaches with neck stiffness or heart palpitations. Months to years later repeated episodes of joint pain and swelling may occur. Occasionally shooting pains or tingling in the arms and legs may develop. Despite appropriate treatment about 10 to 20% of those affected develop joint pains, memory problems and tiredness for at least six months. ...

Endoflagella
A spirochaete () or spirochete is a member of the phylum Spirochaetota (), (synonym 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 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 about. When reproducing, a spirochaete will undergo asexual transverse binary fission. Most spirochaetes are free-living and anaerobic, but there are numer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Borrelia Mayonii
''Borrelia mayonii'' is a Gram-negative, host-associated spirochete that is capable of causing Lyme disease. This organism can infect various vertebrate and invertebrate hosts such as humans and ticks, primarily '' Ixodes scapularis''. Migratory songbirds play a role in the dispersal of the tick vector, ''Ixodes scapularis'', across long distances, indirectly dispersing ''Borrelia mayonii'' as well. 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''.

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 Sta ...

Relapsing Fever
Relapsing fever is a vector-borne disease caused by infection with certain bacteria in the genus '' Borrelia'', which is transmitted through the bites of lice or soft-bodied ticks (genus ''Ornithodoros''). Signs and symptoms Most people who are infected develop sickness between 5 and 15 days after they are bitten. The symptoms may include a sudden fever, chills, headaches, muscle or joint aches, and nausea. A rash may also occur. These symptoms usually continue for 2 to 9 days, then disappear. This cycle may continue for several weeks if the person is not treated. Causes Louse-borne relapsing fever Along with '' Rickettsia prowazekii'' and ''Bartonella quintana'', '' Borrelia recurrentis'' is one of three pathogens of which the body louse (''Pediculus humanus humanus'') is a vector. Louse-borne relapsing fever is more severe than the tick-borne variety. Louse-borne relapsing fever occurs in epidemics amid poor living conditions, famine and war in the developing world. It ...
