Prevention of tick bites: an evaluation of a smartphone app

Lyme borreliosis (LB) is the most common reported tick-borne infection in Europe, and involves transmission of Borrelia by ticks. As long as a vaccine is not available and effective measures for controlling tick ...

Authors: Brodziński S, Nasierowski T Abstract In the second part of the article case reports of three patients were presented. All patientswere treated for Borrelia infection and all of them developed psychotic disorders. History of each patient was different, as well as the probability of causal relationship between neuroborreliosis and psychosis. The first case concerns a female patient with no former psychiatric history, who developed psychotic episode secondary to neuroborreliosis. Psychotic disorders resolved after antibiotic treatment. In the second case, a male patient was previously twice hospitalized in p...

Borrelia burgdorferi is a tick-borne bacterium responsible for approximately 300,000 annual cases of Lyme disease (LD) in the United States, with increasing incidences in other parts of the world. The debilitating nature of LD is mainly attributed to the ability of B. burgdorferi to persist in patients for many years despite strong anti-Borrelia antibody responses. Antimicrobial treatment of persistent infection is challenging. Similar to infection of humans, B. burgdorferi establishes long-term infection in various experimental animal models except for New Zealand White (NZW) rabbits, which clear the spirochete within 4 t...

In this study, we applied complementary in silico approaches to modeling how Anaplasma phagocytophilum infection modulates tick vector regulome. This proof-of-concept research provided support for the use of network analysis in the study of regulome response to infection, resulting in new information on tick-pathogen interactions and potential targets for developing interventions for the control of tick infestations and pathogen transmission. Deciphering the precise nature of circuits that shape the tick regulome in response to pathogen infection is an area of research that in the future will advance our knowledge of tick-...

The tick-borne pathogen Borrelia burgdorferi is responsible for approximately 300,000 Lyme disease (LD) cases per year in the United States. Recent increases in the number of LD cases, in addition to the spread of the tick vector and a lack of a vaccine, highlight an urgent need for designing and developing an efficacious LD vaccine. Identification of protective epitopes that could be used to develop a second-generation (subunit) vaccine is therefore imperative. Despite the antigenicity of several lipoproteins and integral outer membrane proteins (OMPs) on the B. burgdorferi surface, the spirochetes successfully evade anti...

In this study, we evaluated two mouse models - the C3H/N and Balb/c strains for susceptibility to infection and ability to transmit the pathogens via tick vector and to reveal the potential interactions between various bacterial tick-borne agents. Our results indicated that the C3H/N and Balb/c mice are well-accepted models of B. afzelii infection. However, they are not suitable for interaction studies with R. helvetica since the animals did not acquire rickettsiemia and do not transmit Rickettsia sp. to feeding ticks.

“Doesn’t it typically happen during the summer?” asked a worried lady that had walked into my clinic in November with a growing circular rash on her wrist. She was referring, of course, to Lyme disease, that scourge of outdoor enthusiasts. While the peak season for Lyme disease is indeed summer, the ticks that transmit it are active March through December. And, while this may be off-season for the ticks, it is a good time to catch up on how to stay safe in the not-so-distant spring. What is Lyme disease, and how do you treat it? Lyme disease is caused by a bacterium called Borrelia burgdorferi which is sp...

The objective of our study was to provide a snapshot map of the risk of human infection with B. burgdorferi s. l. pathogens in a periurban forest at a high resolution, and to analyze the factors that contribute to variation in this risk. Field monitoring took place over three weeks in May 2011 in the suburban Sénart forest (3,200ha; southeast of Paris), which receives over 3 million people annually. We sampled ticks over the entire forest area (from 220 forest stands with a total area of 35,200 m2) and quantified the density of questing nymphs (DON), the prevalence of infection among nymphs (NIP), and the density of...

In this study, we have identified a Salp15 homolog, designated as Iaff15, from Ixodes affinis ticks that are the principal enzootic vectors of B. burgdorferi sensu stricto in the southeastern part of the United States. Comparison of the annotated amino acid sequences showed that Iaff15 share 81% homology with I. sinensis Salp15 homolog and 64% homology with I. scapularis Salp15. Phylogenetic analysis revealed that Iaff15 come within the same clade with I. sinensis, I. scapularis and I. pacificus Salp15 homologs. The bioinformatics analysis of the posttranslational modifications prediction revealed that all the Salp15 famil...

There are several good reasons to keep ticks off your body. One is that they are creepy and suck your blood. Another is that they can transmit 14 different diseases—not just Lyme disease. A report published online this week in the journal Annals of Internal Medicine describes the newest tick-borne disease in North America, which is caused by a bacterium known as Borrelia miyamotoi. The microbe was first identified in Japan in 1995. The first report of it infecting humans came from Russia in 2011. Cases began appearing in the northeastern United States in 2013. Borrelia miyamotoi is a spiral-shaped bacterium that is r...

Publication date: Available online 28 April 2015 Source:Ticks and Tick-borne Diseases Author(s): Vanessa Cook , Alan G. Barbour Peromyscus leucopus, the white-footed mouse, is one of the more abundant mammals of North America and is a major reservoir host for at least five tickborne diseases of humans, including Lyme disease and a newly-recognized form of relapsing fever. In comparison to Mus musculus, which is not a natural reservoir for any of these infections, there has been little research on experimental infections in P. leucopus. With the aim of further characterizing the diversity of phenotypes of host responses, ...
