a genus of gram-negative, aerobic, spirochete bacteria that are parasites on mucous membranes and cause borreliosis and other conditions. B. burgdor´feri, transmitted by ixodid ticks, is the cause of acrodermatitis chronica atrophicans, erythema chronicum migrans, and lyme disease. B. recurren´tis is transmitted by the human body louse Pediculus humanus and causes epidemic relapsing fever in various countries around the world. A number of other species are spread by tick bites and also cause relapsing fever.
A genus of bacteria (family Treponemataceae) containing cells 8-16 mcm in length, with coarse, shallow, irregular spirals and tapered, finely filamented ends. These organisms are parasitic on many forms of animal life, are generally hematophytic, or are found on mucous membranes; most are transmitted to animals or humans by the bites of arthropods. The type species is Borrelia anserina. Within the Borrelia burgdorferi sensu lato complex, three pathogenic groups have been identified in North America; all strains identified to date as human pathogens belong to the genospecies Borrelia burgdorferi sensu stricto.
Borrelia/Bor·rel·ia/ (bah-rel´e-ah) a genus of bacteria (family Spirochaetaceae), parasitic in many animals. B. burgdor´feri causes Lyme disease and skin disease, and numerous species cause relapsing fever.
A genus of spirochetes that includes species that cause Lyme disease and relapsing fever.
Any of various spirochetes of the genus Borrelia that are pathogens of humans, other mammals, and birds, including the causal agents of Lyme disease and relapsing fever.
Etymology: Amédée Borrel, French bacteriologist, 1867-1936
a genus of coarse, unevenly coiled helical spirochetes, several species of which cause tick-borne and louseborne relapsing fever. The organism is spread to offspring from generation to generation. This does not occur in lice. Many animals serve as reservoirs and hosts for Borrelia. The spirochete may be identified by microscopic examination of a smear of blood stained with Wright's stain; it is also easily inoculated onto culture media for bacterial culture and identification.

BorreliaA genus of spiral-shaped bacteria that includes the organism Borrelia burgdoferi responsible for LYME DISEASE and Borrelia recurrentis that causes RELAPSING FEVER. (Amedee Borrel, 1867–1936, Strasbourg bacteriologist).
a genus of spiral, gram-negative bacteria. The spirals have a long amplitude and are irregular.
causes fowl spirochetosis.
causes lyme disease in humans and animals.
causes relapsing fever in humans, and a subclinical disease in Virginia opossum, one of the major reservoirs of the disease.
not an accredited species. Originally identified as a cause of ulcerative granuloma of swine.
cause of theileriasis in cattle, sheep and horses.
