Characterization of 5′-methylthioadenosine/S-adenosylhomocysteine nucleosidases from Borrelia burgdorferi: Antibiotic targets for Lyme disease

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.

Publication date: September 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 5Author(s): Tiffany Wong, Simin GoralLupus nephritis (LN) is the cause of end-stage kidney disease (ESKD) for 1.9% of the ESKD population in the United States. Although the incidence rates of ESKD from LN stopped rising in recent years, racial disparities in waiting time, pre-emptive kidney transplant, and transplant outcomes still exist. Patients with LN who progress to ESKD tend to be female, of African ancestry, and young. Kidney transplantation is safe in this population and associated with a substantial survival benefit, prima...

Few studies explore how diarrhoeal mortality varies subnationally, especially by cause, which is important for targeting investments. Even fewer examine indirect effects of diarrhoeal morbidity on child mortality. We estimated the subnational d...

Unlike typical Fur proteins in which DNA binding represses gene expression, binding of BosR to the rpoS promoter directly activates rpoS transcription in B. burgdorferi. However, virtually nothing is known concerning potential structural fea...

In this study, bird species migrating through Bulgaria were investigated as carriers of zoonotic pathogens. In total, 706 birds belonging to 46 species were checked for the presence of various bacterial pathogens (Campylobacter, Yersin ia, Salmonella, Listeria, Escherichia coli, Staphylococcus aureus, Francisella tularensis, Coxiella burnetii, Borrelia burgdorferi, and Brucella spp.). From 673 birds we investigated fecal samples, from the remaining 33, blood samples. We detected Campylobacter 16S rDNA gene in 1.3% of birds, but no ne were of pathogenic Campylobacter jejuni and Campylobacter coli species. Escherichia coli 1...

Answer:Borreliaspp., relapsing fever group. Molecular studies are needed to definitively identify the causative agent. However, knowing the exposure history of the patient also helps narrow the differential. In this case, we later found out that the patient is from the northwestern part of North America, and therefore this is most likelyBorrelia hermsii,one of the tick-borne relapsing feverBorreliaspecies.The other tick-borneBorreliain North America areB. parkeriiandB. turicatae.These species are transmitted through the bite of a soft-bodied tick in the genusOrnithodoros,and are usually associated with exposure to'rustic's...
