Molecular interactions during Borrelia burgdorferi migration from the vector to the mammalian nervous system.

CONCLUSION: Different specific molecules of the vector, pathogen and host result in LNB establishment. After B. burgdorferi species penetrate host skin through a tick bite, they are confronted by the immune defenses of the host. However, they are helped by specific proteins in different interactions, and the disease is established. The interactions between the vector, pathogen and host are shown in Table 1 and Figure 1. Knowledge of these molecular interactions can aid development of therapeutics against LNB and LD. Others: We systematically describe the different molecular tick-pathogen-host interactions.

In Japan, Ixodes persulcatus is a major vector for Lyme borreliosis pathogens, such as Borrelia garinii, as well as for those causing relapsing fever, s...

Lyme disease is caused by a tick-borne bacterium Borrelia sp. This zoonotic infection is common in the Northern Hemisphere, e.g., Europe. Clinical presentation may involve multisystem symptoms and depends on the stage of the disease. The involvement of nervous system in Lyme disease is commonly referred to as neuroborreliosis. Neuroborreliosis may involve meningitis, mononeuritis multiplex, or cranial neuritis including the inflammation of vestibulocochlear nerve. In the late or chronic stage of Lyme disease, vestibular involvement may be the sole presentation, although such cases are rare. Our study was designed to presen...

CONCLUSIONS: This study demonstrates the potential danger from the inadvertent introduction of novel disease pathogens and vectors. Awareness of co-infections and Dermacentor reticulatus-related pathogens needs to be increased. PMID: 31694625 [PubMed - in process]

ConclusionB. burgdorferi is unusual in that it expresses three distinct MTNs (cytoplasmic, membrane bound, and secreted) that are effectively inactivated by nucleoside analogs.General significanceThe Borrelia MTNs appear to be promising targets for developing new antibiotics to treat Lyme disease.

LYME disease is an infectious disease caused by a bacterium named Borrelia, spread by ticks found in the woods. It can easily be caught and if a person experiences this one particular sign it could be a major warning that you may be at risk of having the disease. What is it?

Abstract Borrelia turcica, a member of the reptile-associated Borrelia clade, is vectored by Hyalomma aegyptium. The only suggested reservoir hosts of B. turcica are tortoises of the genus Testudo. Borrelia turcica has been described to occur in several Southeastern European countries including Turkey, Romania, Bulgaria and Greece but so far nothing is known about the relationship of these populations and whether or how they are structured. Using multilocus sequence typing (MLST) on eight chromosomally located housekeeping loci (clpA, clpX, nifS, pepX, pyrG, recG, rplB and uvrA) we analyzed 43 B. turcica isolates ...

Conclusions: In Slovenia, LNB in children is more often caused by B. garinii, followed by B. afzelii. The clinical picture of LNB in children caused by B. garinii is not more often suggestive of CNS involvement, but CNS inflammation is more pronounced in children infected with B. garinii, compared with children infected with B. afzelii.

This study documents a high prevalence in ticks of Rickettsia spp. thought to be endosymbionts, a low prevalence of relapsing fever group Borrelia in ticks, and a lack of detection of Lyme disease-group Borrelia in both ticks and mammals in an east Texas forested recreation area. Additionally, we observed low questing tick density in areas with a history of controlled burns. These results expand knowledge of tick-borne disease ecology in east Texas which can aid in directing future investigative, modeling, and management efforts.
