Borrelia is a genus of bacteria of the spirochete phylum. [1] 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. [2] A few Borrelia species as Candidatus Borrelia mahuryensis harbor intermediate genetic features between Lyme disease and relapsing fever Borrelia. [3] 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 . [4] This bacterium must be viewed using dark-field microscopy, [5] which make the cells appear white against a dark background. Borrelia species are grown in Barbour-Stoenner-Kelly medium. [5] Of 52 known species of Borrelia, 20 are members of the Lyme disease group (with an additional 3 proposed), [6] 29 belong to the relapsing fever group, and two are members of a genetically distinct third group typically found in reptiles. [4] A proposal has been made to split the Lyme disease group based on genetic diversity and move them to their own genus, Borelliella, [7] but this change is not widely accepted. [4] This bacterium uses hard and soft ticks and lice as vectors. [8] [9] Testing for the presence of the bacteria in a human includes two-tiered serological testing, including immunoassays and immunoblotting. [10]

Biology

Borrelia species are members of the family Spirochaetaceae, so present the characteristic spirochete (spiral) shape. Most species are obligate anaerobes, although some are aerotolerant. [11] 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]

Spirochetes move using axial filaments called endoflagella in their periplasmic space. [5] The filaments rotate in this space, between the outer membrane and the peptidoglycan layer, propelling the bacterium forward in a corkscrew-like motion. [5] The outer membrane of Borrelia species contains outer surface proteins (Osp) that play a role in their virulence. [5]

Vectors

Ticks

Hard ticks of the family Ixodidae are common vectors of Borellia bacteria [20] and are the only type of ticks shown to transmit Lyme disease bacteria to humans. [21] Some tick species of the Ambylomma genus are vectors of Candidatus Borrelia mahuryensis in South America. [3]

Global hard tick species that cause Lyme disease [8]
RegionTick speciesCommon name
East and Midwest (US) Ixodes scapularis Black-legged tick, deer tick
Pacific Coast (US) Ixodes pacificus Western black-legged tick
Europe Ixodes ricinus Sheep tick
Asia Ixodes persulcatus Taiga tick

Other species are carried by soft ticks. The soft tick Ornithodoros carries the species of Borellia that cause relapsing fever. [9] Another species, B. anserina, is carried by the soft tick Argas . [4] Inside the ticks, the bacteria grow in the midgut and then travel to the salivary glands to be transmitted to a new host. [21] Ticks can spread the bacteria to each other when co-feeding. [20] If an animal has been infected by a tick and then is bitten by a second tick, the second tick can become infected. [22] The bacteria are most commonly transmitted to humans through ticks in the nymph stage of development, because they are smaller and less likely to be noticed and removed. [22] The ticks must have around 36 to 48 hours of contact with a host to successfully transmit the bacteria. [22]

Lice

Lice that feed on infected humans acquire the Borrelia organisms that then multiply in the hemolymph and gut of the lice. [9] When an infected louse feeds on an uninfected human, the organism gains access when the victim crushes the louse or scratches the area where the louse is feeding. [9] The U. S. Centers for Disease Control and Prevention reported that no credible evidence shows that lice can carry Borrelia. [22]

Pathology

Lyme disease

Of the 52 known species of Borrelia, 20 belong to the Lyme disease group and are transmitted by ticks. [4] Eight are known to cause Lyme disease or Borreliosis. [6] The major Borrelia species causing Lyme disease are Borrelia burgdorferi , Borrelia afzelii , and Borrelia garinii . [23] All species that cause Lyme disease are referred to collectively as B. burgdorferisensu lato, [10] while B. burgdorferi itself is specified as B. burgdorferisensu stricto. [10] [21] B. burgdorferi was previously believed to be the only species to cause Lyme disease in the US, but B. bissettiae and a new species called B. mayonii cause Lyme disease in the US, as well. [23] The remaining five human pathogenic species occur only in Europe and Asia.

Relapsing fever

Relapsing fever (RF) borreliosis often occurs with severe bacteremia. [24] Twenty-five species of Borrelia are known to cause relapsing fever. [25] While most species use the soft tick family Argasidae as their vector, some outliers live in hard ticks or lice. [25] Relapsing fever can be spread epidemically through lice or endemically through ticks. [9]

B. recurrentis, a common species underlying relapsing fever, is transmitted by the human body louse; no other animal reservoir of B. recurrentis is known. [9] B. recurrentis infects the person via mucous membranes and then invades the bloodstream. [9]

Other tick-borne relapsing infections are acquired from other species, such as B. hermsii , B. parkeri , or B. miyamotoi , [26] which can be spread from rodents, and serve as a reservoir for the infection, via a tick vector. B. hermsii and B. recurrentis cause very similar diseases, although the disease associated with B. hermsii has more relapses and is responsible for more fatalities, while the disease caused by B. recurrentis has longer febrile and afebrile intervals and a longer incubation period.

Borellia miyamotoi disease

Diagnosis

Direct tests include culture of Borrelia from skin, blood, or cerebrospinal fluid (CSF), and detection of genetic material by polymerase chain reaction in skin, blood, or synovial fluid. Two-tiered serological testing is performed for differential diagnosis of Borrelia infection. The first-tier tests detect specific antibodies (IgM and IgG together or separately) and include enzyme-linked immunoassays (e.g. ELISAs) and immunofluorescent assays. Positive results for first-tier tests are confirmed using second-tier testing. The second tier consists of standardized immunoblotting, either by using Western blots or blots striped with diagnostically important purified antigens. Positive results for second-tier tests are confirmatory for the presence of Borrelia infection. [10] [27] Spirochetes can also be seen using Wright-stained blood smears. [9]

A spirochaete or spirochete is a member of the phylum Spirochaetota, which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled cells. Spirochaetes are chemoheterotrophic in nature, with lengths between 3 and 500 μm and diameters around 0.09 to at least 3 μm.

<span class="mw-page-title-main">Lyme disease</span> Infectious disease caused by Borrelia bacteria, spread by ticks

Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding 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 six months or more; this constellation of symptoms is termed post-treatment Lyme disease syndrome (PTLDS).

Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. The economic impact of tick-borne diseases is considered to be substantial in humans, and tick-borne diseases are estimated to affect ~80 % of cattle worldwide. Most of these pathogens require passage through vertebrate hosts as part of their life cycle. Tick-borne infections in humans, farm animals, and companion animals are primarily associated with wildlife animal reservoirs. Many tick-borne infections in humans involve a complex cycle between wildlife animal reservoirs and tick vectors. The survival and transmission of these tick-borne viruses are closely linked to their interactions with tick vectors and host cells. These viruses are classified into different families, including Asfarviridae, Reoviridae, Rhabdoviridae, Orthomyxoviridae, Bunyaviridae, and Flaviviridae.

<i>Borrelia burgdorferi</i> Species of bacteria

Borrelia burgdorferi is a bacterial species of the spirochete class in the genus Borrelia, and is one of the causative agents of Lyme disease in humans. Along with a few similar genospecies, some of which also cause Lyme disease, it makes up the species complex of Borrelia burgdorferi sensu lato. The complex currently comprises 20 accepted and 3 proposed genospecies. B. burgdorferi sensu stricto exists in North America and Eurasia and until 2016 was the only known cause of Lyme disease in North America. Borrelia species are Gram-negative.
