A recent study conducted by researchers at the University of California Davis provides new insights into Borrelia burgdorferi, the bacterium that causes Lyme disease. The study found that infection with B. burgdorferi leads to continuous production of IgM antibodies, which are mainly produced by conventional B cells in a T-independent manner.

A new study conducted by researchers at the National Institute of Hematology in Budapest, Hungary, explores the diagnosis of neuroborreliosis (NB) in the context of local seroprevalence. The study compares the efficacy of different methods and assesses the prevalence of anti-Borrelia antibodies in the local population. The researchers found that recombinant antigen-based two-tier serology from sera alone may have sufficient positive predictive value to verify NB in young individuals with characteristic anamnestic data in the region. However, when parallel serum-CSF testing is necessary, the antibody-index (AI) should be prioritized. The study emphasizes the importance of considering various factors, such as IgG and albumin concentrations, exposure time, and symptom duration, for conclusive testing. [Extracted from the article]

A study conducted at the University of Delaware examined the diversity and host specificity of Borrelia burgdorferi's outer surface protein C (ospc) alleles in synanthropic mammals. The researchers used metagenomics to sequence ospC alleles from infected individuals belonging to eight mammalian species trapped in suburban New Jersey. They found that multiple allele infections were common, with certain alleles being more prevalent in specific host species. The study suggests that one particular allele, allele U, may exclude other alleles, reducing the capacity of chipmunks to act as reservoirs for certain ospC alleles. The research was supported by the National Science Foundation and has been peer-reviewed. [Extracted from the article]
