List of Tick Borne Diseases

Did you just find a tick on yourself or a loved one? TickCheck can test your tick and determine whether it carries the bacteria that transmit Lyme disease and other tick-borne infections.

Ticks can carry a wide range of diseases.

As one of the most dangerous disease vectors in North America, there are over a dozen tick-borne diseases of various severity which can be transmitted to both humans and animals through a tick bite. It can take weeks for human testing to detect these vectors.

At TickCheck, we can determine if your tick carries any of the disease-causing agents below. The most common tick-borne disease in the wild, and our most commonly requested test, is for Lyme disease. To order a tick test, visit the tick test order form.

  • Microscopic image of Borrelia burgdorferi

    Lyme disease (Borrelia burgdorferi)

    Lyme disease, caused by the bacteria Borrelia burgdorferi, is the most common tick-borne disease in the northern hemisphere. Lyme disease is transferred by the bite of an infected tick, and is dangerous to both people and pets. Infection can cause severe long-term health issues including fever, fatigue, migraines, and skin rash. Left untreated, Lyme disease can spread to the joints, heart, and nervous system. With prompt diagnosis, Lyme disease can be successfully treated with several weeks of strong antibiotics.

  • Microscopic image of Anaplasma phagocytophilum

    anaplasmosis (Anaplasma phagocytophilum)

    Anaplasmosis (formerly HGE Ehrlichia, or Human Granulocytic Ehrlichiosis) is a tick-borne disease caused by the bacterium Anaplasma phagocytophilum. Left untreated, anaplasmosis can result in bleeding or kidney failure. Anaplasma infections are also common in dogs. This disease has immediate symptoms similar to Lyme disease, and is thus difficult to diagnose and treat without lab analysis of the tick vector. Our lab uses PCR to determine the existence of the bacterium in a tick specimen.

  • Microscopic image of Babesia microti

    babesiosis (Babesia microti)

    Babesia is a tick-borne protozoan parasite that causes symptoms similar to malaria, and can pose severe health issues or even death in individuals with weak immune systems. Babesia can also cause problems in dogs. Babesia is curable in humans and animals with several modern antibiotic treatments. Our lab can determine if your tick specimen was infected with Babesia protozoa.

  • Microscopic image of Bartonella spp.

    bartonellosis (Bartonella spp.)

    Bartonella is a disease-causing bacterium transmittable to both humans and other mammals. Bartonella is the primary agent of Cat scratch disease (CSD), which has symptoms such as swollen lymph nodes, headaches, and abdominal pain.

  • Microscopic image of Ehrlichia chaffeensis

    ehrlichiosis (Ehrlichia chaffeensis)

    human monocytic ehrlichiosis

    HME Ehrlichia, or Human Monocytotropic Ehrlichiosis, is a tick-borne disease caused by the bacterium Ehrlichia chaffeensis. The bacterium infects the immune system, and can cause serious health issues including bleeding disorders. Other symptoms include fever, headache, and myalgia. When discovered, Ehrlichiosis is treatable with the antibiotic Doxycycline. Our lab can determine if your specimen is a carrier of Ehrlichia species, however our test is not specific to E. chaffeensis.

  • Microscopic image of Rickettsia spp.

    Rocky Mountain spotted fever (Rickettsia spp.)

    Rocky Mountain Spotted Fever is the most lethal and most frequently reported rickettsial illness in the United States. Caused by the bacterium Rickettsia rickettsii and spread by Dog ticks and Lone Star ticks, the disease results in fever, abdominal pain, and a spotted rash on the skin. If not treated promptly, Rocky Mountain spotted fever can be fatal. However, prompt modern antibiotic therapy has dramatically reduced the number of deaths caused by the disease. Our lab can determine if your specimen is a carrier of Rickettsia species, but is not specific to Rickettsia rickettsii.

  • Microscopic image of Francisella tularensis

    tularemia (Francisella tularensis)

    Tularemia, also known as Pahvant Valley plague or Rabbit Fever, is a tick-borne disease caused by the bacterium Francisella tularensis. Used as a biological weapon in the past, Tularemia is extremely infectious and can result in fever, lethargy, anorexia, septicemia (blood infection), and even death. If diagnosed, Tularemia is treatable with powerful antibiotics like streptomycin or doxycycline.

  • Microscopic image of Borrelia miyamotoi

    B. miyamotoi (Borrelia miyamotoi)

    Borrelia miyamotoi is a spiral-shaped bacterium that can transferred to humans through the deer tick. It is related to the bacterium that causes Lyme disease. Although infection can cause some similar symptoms including fever, headache, fatigue, and muscle aches, acute Lyme disease often presents with rash while infection with B. miyamotoi does not. Physicians have successfully treated patients infected with B. miyamotoi with a 2-week course of doxycycline.

  • Microscopic image of Borrelia lonestari

    STARI (Borrelia lonestari)

    southern tick-associated rash illness

    Borrelia lonestari is suspected of causing STARI, however, further research is does not support this idea. Currently, no diagnostic test is available for STARI, and no official treatment protocol exists, though antibiotics are generally prescribed.

  • Microscopic image of Babesia spp.

    babesiosis (Babesia spp.)

    Babesia is a tick-borne protozoan parasite that causes symptoms similar to malaria, and can pose severe health issues or even death in individuals with weak immune systems. Babesia can also cause problems in dogs. Babesia has become more common in recent years, and is found in ticks even more frequently then Lyme disease. Babesia is curable in humans and animals with several modern antibiotic treatments. Our lab can determine if your tick specimen was infected with Babesia protozoa.

  • Microscopic image of Bartonella henselae

    cat-scratch fever (Bartonella henselae)

    cat-scratch disease

    Cat-scratch disease (CSD) is a bacterial infection spread by cats. The disease spreads when an infected cat licks a person's open wound, or bites or scratches a person hard enough to break the surface of the skin. About three to 14 days after the skin is broken, a mild infection can occur at the site of the scratch or bite. It is caused by CSD is caused by a bacterium called Bartonella henselae.

  • Rickettsia endosymbiont (Rickettsia endosymbiont)

    Rickettsia endosymbiont is a bacteria found in ticks that aid in the survivial, acquisitio and transmission of pathogenic bacteria. R. endosymbiont has been found in western blacklegged ticks in California. It is hypothesized that R. endosymbiont speeds up the transmission process of other pathogens.

  • mycoplasmosis (Mycoplasma fermentas)

    Mycoplasmosis can cause an array of different symptoms depending on the species that is transmitted. Mycoplasma sp. are the smallest bacteria and have no cell wall which allow them to invade human cells easily and disrupt the immune system. When transmitted by a tick, is commonly found as a co-infection of Lyme disease and Mycoplasma fermentans being the most common species. Symptoms can include fatigue, muscle and joint pain, abdominal bloating, bronchitis and diarrhea. Mycoplasmosis can be treated with a long course of antibiotics.

  • Microscopic image of Powassan virus Lineage II

    Deer tick virus (Powassan virus Lineage II)

    Powassan virus Lineage II

    Powassan virus also known as Deer Tick Virus is transmitted by an infected Blacklegged tick or Groundhog tick. Over the last decade cases have increased in the Northeast and Great Lakes region. Powassan is a potentially fatal disease that can cause fever, vomiting, dizziness, confusion, seizures, coma and encephalitis. Individuals with Powassan may suffer long-term neurological problems. There are no specific treatments for severe Powassan virus illness besides hospital care.

  • Microscopic image of Borrelia mayonii

    Lyme disease (Borrelia mayonii)

    Borrelia mayonii was recently discovered in 2013 in the Wisconsin and is a spirochete bacterium which causes Lyme disease in the United States. It has currently only been found in upper Midwest States. Similar to B. burgdorferi it can cause rash, fever, headache, arthritis but also causes symptoms of nausea, vomiting, diffuse rashes and a higher concentration of bacteria in the blood. B. mayonii can be treated with several weeks of strong antibiotics.

  • Microscopic image of Ehrlichia ewingii

    ehrlichiosis (Ehrlichia ewingii)

    human monocytic ehrlichiosis

    Ehrlichiosis can be a serious infection if not treated in timely manner and is caused by the bacterium Ehrlichia ewingii. Ehrlichiosis can infect the immune system of humans and dogs and cause similar symptoms as E. chaffeensis; fever, headache, muscle pain, confusion and vomiting/diarrhea. Unlike E. chaffeensis, E. ewingii does not commonly have a rash and usually infects granulocytes. Ehrlichiosis is treatable with doxycycline.

  • Rocky Mountain spotted fever (Rickettsia amblyommii)

    Rickettsia amblyommii is part of the spotted fever group of Rickettsia. It is an obligate intracellular bacteria that has been found to cause symptoms similar to Rocky Mountain spotted fever (RMSF). R. amblyomii is currently still being researched to fully understand it pathogenicity to humans.
