Mouse, not just tick: New genome heralds change in Lyme disease fight

(University of California - Irvine) As Lyme disease increases, researchers have taken a significant step toward finding new ways to prevent its transmission. The experts, who include a pioneer in Lyme disease discovery, have sequenced the genome of the animal carrying the bacteria that causes the illness. The advance by researchers at the University of California, Irvine and colleagues provides a launching pad for fresh approaches to stopping Lyme disease from infecting people.

Harms and colleagues advised a single dose of doxycycline to prevent Lyme disease from a Ixodes ricinus tick bite.1 Using a modified-intention-to-treat analysis, the authors that reported a single 200 mg dose of doxycycline resulted in a 67% relative risk reduction for the subjects in the treatment arm.

We report the results of gene expression profiling via RNA-sequencing of primary human choroid plexus epithelial cells in vitro that were infected with Borrelia burgdorferi, the causative agent of Lyme disease. Epithelial cells were cultured with B. burgdorferi for 48 hours prior to RNA isolation. Following high-throughput sequencing via Illumina HiSeq 4000, a total of 258 differentially expressed genes were identified. Subsequent data analysis indicates an inflammatory and immune response generated by the epithelial cells following infection, marked by chemotactic cytokines and interferon stimulated genes. Several genes a...

We examined the effect of a positive serostatus at baseline for selected pathogens associated with chronic infections (Helicobacter pylori,Borrelia burgdorferi sensulato,Toxoplasma gondii, cytomegalovirus, Epstein-Barr virus, herpes simplex virus 1/2, and human herpesvirus 6) on all-cause mortality with multivariable parametric survival models. We found a reduced survival time in individuals with a positive serostatus forHelicobacter pylori (accelerated failure time (AFT) − 15.92, 95% CI − 29.96; − 1.88), cytomegalovirus (AFT − 22.81, 95% CI − 36.41; −&...

(CNN) — After more than three months of shutdowns, mandatory quarantines, self-imposed exile from society and working from home, nature-lovers looking for a well-earned breath of fresh air could face a possible collision course between coronavirus and tick-borne illnesses this summer. A “perfect storm,” warns Eva Sapi, a University of New Haven biology professor and group director for the Lyme Disease Research Group. Noting the mild winter on the East Coast, Sapi says, “We do have a bad year for the ticks.” Hikers, campers and anyone else eager for an escape could “just explode into...

AbstractModified two-tier testing (MTTT) for Lyme borreliosis (i.e. confirmation with an EIA instead of an immunoblot) has been shown to have improved sensitivity compared with standard two-tier testing (STTT) in samples from American patients, without losing specificity. The current study assesses the sensitivity and specificity of various algorithms of MTTT in European patients with erythema migrans (EM) as a model disease for early Lyme borreliosis, and in appropriate controls. Four different immunoassays were used in the first tier, followed by either an immunoblot or the C6-EIA, or were  used as standalone single...
