CE: Lyme Disease: Diagnosis, Treatment, and Prevention.

CE: Lyme Disease: Diagnosis, Treatment, and Prevention. Am J Nurs. 2018 Mar 14;: Authors: Patton SK, Phillips B Abstract Evidence-based strategies for nurses. ABSTRACT: Lyme disease is recognized as the most common vector-borne disease in the United States. Surveillance data indicate both increasing numbers of Lyme disease cases and geographic expansion of areas where the causative spirochete, Borrelia burgdorferi, can be found. With prompt diagnosis and appropriate treatment in the acute stage, most patients will recover fully. Without treatment, however, the infecting pathogen remains within the body, often producing long-term complications, including musculoskeletal, neurologic, and cardiovascular effects. The authors describe early and late manifestations of Lyme disease, the appropriate use of diagnostic tests, the recommended treatment, and strategies for preventing tickborne diseases nurses can share with patients.

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...

The pharmaco- and immunomodulatory properties of insect and acarine saliva play an essential role in the efficiency of pathogen transmission.

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. ...

Conclusion: The study demonstrates an association between MD and positive tests for both Bb and RFB spirochetes. In conjunction with previous studies, our study provides corroborative evidence linking MD to Borrelia infection and tick-borne illness. PMID: 30519067 [PubMed]

Nymphal and larval stages, and the pathogens transmitted by I. scapularis are maintained in a zoonotic cycle involving rodent reservoir hosts, predominantly Peromyscus leucopus. Humans are not reservoir hosts, however, accidental encounters of infected ticks with humans, results in pathogen tran...

The objective of this work was to determine the prevalence of Borrelia and Bartonella species in Ixodes spp. ticks collected from 16 USA states. Genus PCR amplification and sequence analysis of Bartonella and Borrelia 16SsRNA-23SsRNA intergenic regions were performed on DNA extracted from 929 questing adult ticks (671 Ixodes scapularis, 155 Ixodes affinis, and 103 Ixodes pacificus). Overall, 129/929 (13.9%) Ixodes ticks were PCR positive for Borrelia burgdorferi sensu stricto, 48/929 for B. bissettiae whereas 23/929 (2.5%) were PCR positive for a Bartonella henselae. Borrelia bissettiae or B. burgdorferi s.s. and B. hensel...

SalminenAbstractBacteria of the genus Borrelia cause vector-borne infections like the most important hard tick-borne disease in the northern hemisphere, Lyme borreliosis (LB), and soft tick or louse transmitted relapsing fevers (RF), prevalent in temperate and tropical areas. Borrelia burgdorferi sensu lato (s.l.) includes several genospecies and causes LB in humans. In infected patients, Borrelia burgdorferi sensu stricto (s.s.) expresses the BmpA, BmpB, BmpC and...

Canadian Journal of Microbiology, e-First Articles. Lyme disease is a tick-borne disease that is emerging in Canada. The disease is caused by spirochetes of the Lyme borreliosis group, which is expanding as new species are discovered. In Canada, Lyme disease risk has so far been assessed primarily by detection of Borrelia burgdorferi sensu stricto. Of Ixodes scapularis ticks collected between 2014 and 2016 in New Brunswick, Canada, 7 were shown to be infected with Borrelia bissettii by nested PCR and sequencing of 5 B. bissettii genes. Since different Borrelia species are associated with different clinical manifestations a...

Tufts, Kimberley Gaffett, Brian Tefft, Maria A. Diuk-WasserAbstractAn inverse relationship between biodiversity and human health has been termed the ‘dilution effect’ paradigm. In the case of tick-borne infections such as Lyme disease, the key assumption is that Borrelia burgdorferi sensu lato abundance is increased by the loss of less competent (dilution) hosts as biodiversity declines. White-tailed deer play a dual role in the pathogen cycle, as key repro...
