In the course of performing culture isolation of Borrelia burgdorferi sensu lato for the diagnosis of Lyme borreliosis in Slovenia, we encountered nine patients who were infected with atypical strains. Molecular analyses of these strains suggested that they were more closely related to the North American tick isolate, strain 25015 (which belongs to the(More)
Because of the specificity of Watson-Crick base pairing, attempts are now being made to use oligodeoxynucleotides (oligos) in the therapy of human disease. However, for a successful outcome, the oligo must meet at least six criteria: (i) the oligos can be synthesized easily and in bulk; (ii) the oligos must be stable in vivo; (iii) the oligos must be able(More)
Strain 25015 is an atypical tick isolate that belongs to a distinct genomic group (DN127) within the general taxon Borrelia burgdorferi sensu lato. Similarities between this strain and a white-footed mouse isolate from Illinois, strain CT39, have been reported. In the course of isolating B. burgdorferi sensu lato in culture from Slovenian patients, 9(More)
The compound 2',3'-dideoxycytidine (ddC) is a potent inhibitor of human immunodeficiency virus replication in vitro and is currently in clinical trials for treatment of acquired immunodeficiency syndrome. The compound was found to exert delayed cytotoxicity against Molt-4F cells, a human T lymphoblastic cell line. At a concentration as low as 0.1 microM,(More)
Erythema migrans skin lesions resulting from a tick bite and infection with Borrelia burgdorferi sensu lato eventually resolve, even without antibiotic therapy. The aim of the present study was to gauge the frequency of persistence of B. burgdorferi sensu lato in such lesions. Thus, the site of a previous lesion was biopsied and cultured in 48 patients: 39(More)
We examined the effect of 9-(1,3-dihydroxy-2-propoxymethyl)guanine (DHPG) on viral DNA, RNA, protein, and enzyme synthesis in HeLa cells infected with herpes simplex virus type 1 and type 2. DHPG inhibited virus DNA synthesis in a dose-dependent fashion. This inhibition was not due to the lack of deoxynucleoside triphosphates which are required for DNA(More)
L(-)SddC (3TC) has been shown to be the most promising nucleoside analogue used for the treatment of hepatitis B virus (HBV) infection. Unfortunately, it has been reported that about 12% of HBV-infected patients experience a recurrence of HBV after a period of treatment with 3TC. Point mutations were detected in the HBV polymerase of those viruses from(More)
Several newly discovered potent and selective non-nucleoside inhibitors of human immunodeficiency virus-1 reverse transcriptase (RT) are undergoing evaluation in clinical trials. We studied the potential for development of viral resistance to one of the prototype compounds, BI-RG-587, a dipyridodiazepinone derivative. Human immunodeficiency virus-1(More)
