What is Borrelia burgdorferi?

What does Borrelia burgdorferi cause?

Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii. It is transmitted to humans through the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans.

Is Borrelia the same as Lyme disease?

The scientific name of the bacteria that causes Lyme disease is Borrelia. The two most common diseases caused by Borrelia are Lyme disease and Tick-borne Relapsing Fever (TBRF). Both are transmitted via ticks. Borrelia that cause Lyme disease are collectively known as Borrelia burgdorferi sensu lato.

Where does Borrelia burgdorferi come from?

The bacterium responsible for Lyme disease, Borrelia burgdorferi, originated in America, or so researchers thought. Now, however, scientists has shown that this bug in fact came from Europe, originating from before the Ice Age.

Can Borrelia burgdorferi be cured?

Lyme disease is caused by infection with the bacterium Borrelia burgdorferi. Although most cases of Lyme disease can be cured with a 2- to 4-week course of oral antibiotics, patients can sometimes have symptoms of pain, fatigue, or difficulty thinking that last for more than 6 months after they finish treatment.

Oral antibiotics.

These are the standard treatment for early-stage Lyme disease. These usually include doxycycline for adults and children older than 8, or amoxicillin or cefuroxime for adults, younger children, and pregnant or breast-feeding women.

What is unique about Borrelia burgdorferi?

Borrelia burgdorferi is the spirochete that causes Lyme disease. In contrast to T. pallidum, Borrelia has a unique nucleus containing a linear chromosome and linear plasmids. Borrelia is transmitted by tick bites (Ixodes) during blood feeding.

How is Borrelia burgdorferi contracted?

The Lyme disease bacterium, Borrelia burgdorferi, is spread through the bite of infected ticks. The blacklegged tick (or deer tick, Ixodes scapularis) spreads the disease in the northeastern, mid-Atlantic, and north-central United States.

Diet: B. burgforferi obtains nutrients and energy from the blood of a host. copies of itself with each duplication. They can reproduce rapidly, and one scientific study found an average of 2,735 bacteria/tick 15 days after the tick had fed.

How do you get rid of spirochetes?

Results of the study of three morphological forms of Borrelia in vitro revealed that five antimicrobial drugs commonly used as monotherapy in LD cases (doxycycline, amoxicillin, tigecycline, metronidazole and tinidazole) showed different potential in eradicating spirochetes, round bodies and biofilm-like colonies [102] …

Can late stage Lyme disease be cured?

When treated early, Lyme disease can be cured and most patients will recover completely. Even when treated in later stages, most patients will respond well to antibiotics, though there may be some chronic damage to the nervous system or joints.

What is the best antibiotic for Lyme disease?

Antibiotics. The three first-line oral antibiotics for Lyme disease include doxycycline (Monodox, Doryx, Vibramycin, Oracea), amoxicillin (Amoxil), and cefuroxime (Ceftin, Zinacef). Ceftriaxone (Rocephin) administered intravenously is the preferred antibiotic for neurologic Lyme disease in the United States.

burgdorferi (the bacteria that causes almost all Lyme disease infections in the United States), and the germs that cause anaplasmosis, babesiosis, and Powassan virus disease.

What are the virulence factors of Borrelia burgdorferi?

OspC and DbpA lipoproteins are critical virulence factors of B. burgdorferi (16, 42, 70, 93, 99, 101, 106). These molecules show high variability, and hence, their sequences facilitate discrimination among B. burgdorferi isolates.

What does Borrelia feed on?

Growth kinetic analyses of Borrelia burgdorferi indicated that this bacterium can utilize a limited number of carbon sources for energy: the monosaccharides glucose, mannose, and N-acetylglucosamine, the disaccharides maltose and chitobiose, and glycerol. All of these carbohydrates are likely to be available to B.

How does Borrelia burgdorferi leave the body?

A recent study has shown that Borrelia burgdorferi, the bacterium that causes Lyme disease, spreads throughout the body by crawling along the inside wall—the endothelium—of blood vessels.

Is Borrelia burgdorferi a parasite?

The spirochete Borrelia burgdorferi is a tick-borne obligate parasite whose normal reservoir is a variety of small mammals. Although infection of these natural hosts does not lead to disease, infection of humans can result in Lyme disease as a consequence of the human immunopathologic response to B burgdorferi.

Is Borrelia burgdorferi motile?

Borrelia burgdorferi is a flat-wave, motile spirochete that causes Lyme disease. Motility is provided by periplasmic flagella (PFs) located between the cell cylinder and an outer membrane sheath.

What body system does Lyme disease affect?

Lyme disease can affect different body systems, such as the nervous system, joints, skin, and heart.

What are the long term effects of Lyme disease?

Untreated Lyme disease can cause:
  • Chronic joint inflammation (Lyme arthritis), particularly of the knee.
  • Neurological symptoms, such as facial palsy and neuropathy.
  • Cognitive defects, such as impaired memory.
  • Heart rhythm irregularities.

How do you know if a tick’s head is still in your skin?

How to tell if you got the tick head out? You might have gotten the whole tick with your first attempt at removing it. If you can stomach it, look at the tick to see if it’s moving its legs. If it is, the tick’s head is still attached and you got the whole thing out.

Does Borrelia burgdorferi only cause Lyme disease?

In the United States, the spirochete Borrelia burgdorferi sensu stricto (hereafter termed B burgdorferi) is the only pathogen that causes Lyme disease. However, in Europe and Asia, Borrelia afzelii, Borrelia garinii, and other related species, in addition to B burgdorferi, cause Lyme disease.

What is Borrelia burgdorferi made of?

burgdorferi consists of a protoplasmic cylinder covered by two lipid membranes (Barbour & Hayes, 1986). Between the outer and inner membrane is the periplasmic space that comprises the peptidoglycan layer and flagellar filaments (Kudryashev et al., 2009).
