New Lyme disease tests could offer quicker, more accurate detection

(Rutgers University) New diagnostic methods offer a better chance for more accurate detection of the infection from the Lyme bacteria, the most common tick-borne infection in North America and Europe.

Bashor, Felicia Keesing, Kathleen LoGiudice, Richard S. OstfeldAbstractTick microbiomes may play an important role in pathogen transmission. However, the drivers of microbiome variation are poorly understood, and this limitation has impeded mechanistic understanding of the functions of microbial communities for pathogen acquisition. The goal of this research was to characterize the role of the blood meal host in structuring the microbiome of Ixodes scapularis, the ...

In this study, we investigated tick-borne bacterial pathogens in wild boar, hare, and fox and their ticks in Turkey. A total of 102 tick pools comprised of 445 ticks and blood samples were analyzed for the presence of bacterial DNA by PCRs targeted rickettsial gltA and ompA genes, 5S-23S rDNA gene for Borrelia spp., and msp4 gene for Anaplasma spp. As a result of PCR and sequence analyses, three pathogenic spotted fever group (SFG) rickettsiae, two SFG rickettsiae with unknown pathogenicity and one pathogenic Borrelia burgdorferi sensu lato were detected in samples obtained from wild animals. Rickettsia slovaca was detecte...

This study aims to estimate the incidence of the different clinical manifestations of LB in Belgium. The incidence of erythema migrans (EM) was estimated through the network of sentinel general practices at 97.6/100,000 inhabitants (uncertainty interval [UI] 82.0–113.0) for the period 2015 to 2017. This result was used to estimate the incidence of other LB manifestations based on their proportional distribution (ratios) to EM reported in the neighboring countries of Belgium. To estimate these ratios, we performed a systematic review of studies published between February 1, 2008 and January 31, 2018 and pooled the res...

Long Island, New York, is highly endemic for the disease. The C6 peptide (C6P) is currently used as a screening test for LD in our institution. Our objective was to examine how screening with C6P concorded with diagnosis of LD at the Veterans Affairs Medical Center, Northport, Long Island. ...

Authors: Eldin C, Raffetin A, Bouiller K, Hansmann Y, Roblot F, Raoult D, Parola P Abstract Lyme disease is a tick-borne bacterial disease with polymorphic clinical manifestations (cutaneous, rheumatological, and neurological). In recent years the issue of the diagnosis of this infection has been highly publicized on the Internet and other media in Europe and America. Some patients and physicians may share the perception that the diagnosis of the infection is not reliable in France. We reviewed current European and American guidelines on Lyme disease and performed a methodological evaluation of all guidelines. We r...

Scientists at the University of Cincinnati say the hungrier ticks are, the harder they try to find people or other hosts -- a finding that could have implications for the spread of tick-borne diseases such as Lyme or Rocky Mountain Spotted Fever. The researchers explain that starved ticks' metabolisms speed up, causing them to hunt more aggressively.
