Overview
Lyme disease can be classified into three stages. The first stage is localized Lyme disease, the second is disseminated Lyme disease, and the third is late disseminated Lyme disease. During stage 1, the patient can develop erythema migrans rash. Ten to twenty percent of the patients who have Lyme disease can develop post treatment Lyme disease syndrome. There are various genospecies of Borrelia burgdorferi sensu lato complex that can cause Lyme disease. A novel spirochete, Borrelia mayonii, has been recently discovered to be responsible for Lyme disease.
Classification
Classification based on clinical stage
- Stage 1 is called early localized Lyme disease. The infection is not yet widespread throughout the body.
- Stage 2 is called early disseminated Lyme disease. The bacteria have begun to spread throughout the body.
- Stage 3 is called late disseminated Lyme disease. The bacteria have spread throughout the body.
Classification based on causative organism
- The majority of cases of Lyme disease are caused by Borrelia burgdorferi sensu lato (s.l.) complex. There are 18 genospecies in Borrelia burgdorferi sensu lato (s.l.) complex. Out of these, only 7 infect humans (genotype 3 commonly and 4 occasionally).[1]
| Borrelia burgdorferi sensu lato (s.l.) complex genospecies | ||
|---|---|---|
| Pathogenic | Non-Pathogenic | |
| Commonly infect humans | Rare (no human infection) | Not isolated from humans yet |
|
|
|
- However, B. mayonii has recently been discovered to be responsible for development of Lyme disease.[2]
- The following table demonstrates key clinical and epidemiological features that distinguish B. burgdorferi from B. mayonii:
| General information | B. burgdorferi | B. mayonii
|
|---|---|---|
| Transmission | Tick bite | Tick bite |
| Distribution in the USA | Northeast, Mid-Atlantic, and Midwest regions | Midwest region |
| Bacteria Concentration in Blood (Spirochetemia) | Lower | Higher |
| Early Symptoms | Fever, headache, rash, neck pain | Fever, headache, rash, neck pain |
| Late Symptoms and Complications | Joint pain and arthritis | Joint pain and arthritis |
| Nausea / Vomiting? | No | Yes |
| Rash Characteristics | Bullseye target lesion | Diffuse rash |
| Diagnosis | Serology or PCR | Serology or PCR |
| Treatment | Doxycycline | Doxycycline |
