Borrelia sp. B(2)5, when grown in a medium containing [1-(14)C] linoleic acid in an atmosphere of CO(2), was found to hydrogenate linoleic acid to trans-11-octadecenoic acid.

Abilities to detect heterogeneity of ospC genotypes of the Lyme disease spirochete Borrelia burgdorferi in the tick vector by in vitro culture (IVC) and direct PCR (dPCR) were compared. IVC failed to detect one-third of the ospC genotypes detected by dPCR. Among IVC results, common ospC genotypes were overrepresented while occurrence of rare genotypes was underestimated.

Borrelia burgdorferi B31 cells lacking all linear plasmids or all but the 49-kb linear plasmid expressed the otherwise silent gene for the outer membrane protein OspC. In the first demonstration of a function for a circular plasmid of Borrelia spp., ospC was located on a 27-kb circular plasmid of B31.

During a study of migrating land birds in 1987, we examined over 9,200 individual birds representing 99 species from the Saint Croix River Valley, a Lyme disease-endemic area of east central Minnesota and northwestern Wisconsin. We found that 250 deer tick (Ixodes dammini) larvae and nymphs infested 58 birds from 15 migrant species; 56 ticks (22.4%) were positive for the Lyme disease spirochete...

The aim of our study was to find a possible existence of various vaccination effects on the formation of antibodies against three individual Borrelia afzelii strains (dead cell suspension) isolated from a vector, potential vector and host of this spirochaete, which makes this experiment unique in the research of Lyme disease causative agents. Three strains of Borrelia afzelii were isolated from...

Since Lyme arthritis was first described in the United States, it has now been reported in many countries of Europe. However, very few strains of the causative bacterium, Borrelia burgdorferi, have been isolated from synovial samples. For this reason, different molecular direct typing methods were developed recently to assess which species could be involved in Lyme arthritis in Europe. We devel...

Five Borrelia burgdorferi sensu lato isolates from Missouri are described. This represents the first report and characterization of such isolates from that state. The isolates were obtained from either Ixodes dentatus or Amblyomma americanum ticks that had been feeding on cottontail rabbits (Sylvilagus floridanus) from a farm in Bollinger County, Mo., where a human case of Lyme disease had been...

Lajmska bolest (Lyme borreliosis – L. borreliosis) je infektivno, multisistemsko oboljenje izazvano spirohetom Borrelia burgdorferi (B. burgdorferi) koju na oveka ubodom prenose krpelji roda Ixodes. Bolest može zahvatiti razli ite organe (kožu, nervni sistem, zglobove) prema kojima B. burgdorferi ima tropizam, pa klini ki izgled i tok bolesti mogu biti razli iti . L. borreliosis je tipi na prir...

OBJECTIVE Establishing the seroprevalence of Lyme disease in workers from Cordoba. MATERIAL AND METHODS Representative serum samples (152) were taken from the cities of Montería, Cereté, Lorica and Cotorra in the Córdoba department in Colombia. Borrelia burgdorferi antibodies were detected by ELISA and confirmed by western blot anti-Borrelia blot assay. RPR (rapid plasma regain) test for Trep...
