Lyme disease is a multisystem infection that can affect the joints, heart, and nervous system when untreated. While it can present with cranial nerve palsy, dysphagia is rarely reported. This case highlights a rare instance of dysphagia in Lyme disease, typically known for neurological symptoms like facial nerve palsy. Despite the absence of erythema migrans or a documented tick bite, the patient's facial palsy, hearing loss, vocal cord paralysis, and dysphagia were attributed to Lyme disease. With the rising prevalence of Lyme disease, similar cases may increase, particularly in endemic regions of North America, Europe, and parts of Asia, emphasizing the need for early diagnosis and treatment in patients with unexplained dysphagia.

Borrelia (or Borreliella) burgdorferi, the causative agent of Lyme disease, is a motile and invasive zoonotic pathogen adept at navigating between its arthropod vector and mammalian host. While motility and chemotaxis are well known to be essential for its enzootic cycle, the role of each methyl-accepting chemotaxis proteins (MCPs) in the infectious cycle of B. burgdorferi remains unclear.

We conducted an exploratory study of plasma microbial cell-free DNA sequencing for the diagnosis of Lyme disease among pediatric patients. Low levels of Borrelia burgdorferi microbial cell-free DNA (<3-5 molecules per microliter) were observed in 6/9 serologically confirmed participants, including 4/5 with arthritis and 2/3 with multiple erythema migrans.

Hard ticks (family Ixodidae) are one of the most predominant arthropod disease vectors worldwide, second only to mosquitoes. In addition to harboring animal and human pathogens, ticks are known to carry a microbial community constituted of non-pathogenic organisms, which includes maternally inherited intracellular endosymbionts and other environmentally acquired extracellular microorganisms. These microbial communities, which include bacteria, viruses, protozoans, and fungi-with often commensal, mutualistic, or parasitic associations with the tick-comprise the tick microbiome, bacteria being the most studied community.

Tick-borne diseases are a public health problem and a significant burden on the livestock industry. The seasonal abundance of ticks and tick-borne pathogens strongly correlates with the prevalence of these diseases. To investigate the seasonal variation in ticks and tick-borne pathogens, ticks were collected from Gangwon State, Korea, and the tick-borne pathogens , , , and were examined.

Tick-borne pathogens are growing in importance for human and veterinary research worldwide. We developed, optimized, and validated a reliable quantitative PCR (qPCR; real-time PCR) assay to assess Borrelia burgdorferi infection by targeting two B. burgdorferi genes, and .
