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. [4] [9] [10] 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. [1]
Afzelius published his work 12 years later and speculated the rash came from the bite of an Ixodes tick, meningitic symptoms and signs in a number of cases and that both sexes were affected. This rash was known as erythema chronicum migrans, the skin rash found in early-stage Lyme disease. [18]
Lyme disease is caused by infected black-legged (or deer) ticks and symptoms of the disease may vary, depending on how long it takes to discover the signs. Show comments Advertisement
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]
Signs and Symptoms Radiculopathy is a diagnosis commonly made by physicians in primary care specialties, orthopedics , physiatry , and neurology . The diagnosis may be suggested by symptoms of pain, numbness , paresthesia , and weakness in a pattern consistent with the distribution of a particular nerve root , such as sciatica .
Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. [2]
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.
Due to their role in transmitting Lyme disease, Ixodid ticks, particularly the North American I. scapularis, have been studied using geographic information systems to develop predictive models for ideal tick habitats. According to these studies, certain features of a given microclimate – such as sandy soil, hardwood trees, rivers, and the ...
