| dna analysis of borrelia burgdorferi nch-1, the first northcentral u.s. human lyme disease isolate. | the dna of the first northcentral united states human lyme disease isolate, borrellia burgdorferi nch-1, was characterized and compared with the dnas of nine other b. burgdorferi isolates. strain nch-1 was isolated in august 1989 from a human skin biopsy specimen. dna was analyzed by pulsed-field gel electrophoresis and restriction endonuclease analysis. contour-clamped homogeneous electric field pulsed-field gel electrophoresis of in situ-lysed cells was performed to compare the plasmid profile ... | 1992 | 1551988 |
| analyses of mammalian sera in enzyme-linked immunosorbent assays with different strains of borrelia burgdorferi sensu lato. | blood samples were collected from cottontail rabbits (sylvilagus floridanus), raccoons (procyon lotor), white-footed mice (peromyscus leucopus), and white-tailed deer (odocoileus virginianus) between 1977 and 1991 in southern connecticut and new york state (usa) and were tested for antibodies against eight strains of borrelia burgdorferi sensu lato in enzyme-linked immunosorbent assays. among these spirochetes were six strains of b. burgdorferi sensu stricto, one strain of b. garinii (=ip90) and ... | 1995 | 8583632 |
