Failure rates still too high for treatment of Lyme disease

According to the authors, the 14-day course effectively cleared the patients’ erythema migrans rashes and “prevented the development of objective neurologic, cardiac, or rheumatologic manifestations.” One patient was retreated with amoxicillin.

Lyme-like syndrome in Brazil is still a problem

Brazilian Lyme-like syndrome (BYS) is a tick-borne illness that closely resembles Lyme disease. Recent polymerase chain reaction (PCR) testing has confirmed the presence of Borrelia burgdorferi sensu stricto in Brazil, strengthening evidence that this condition represents a true borrelial infection rather than a distinct or unrelated syndrome. The existence of Borrelia burgdorferi s.s. in Brazil

Diagnosing Borrelia Miyamotoi: Blood Smear Not Reliable

Why Blood Smears Fail to Detect Borrelia miyamotoi Diagnosing Borrelia miyamotoi can be challenging. Some doctors have suggested that a blood smear should be used to confirm the diagnosis of BMD.
