| lyme disease in childhood: report of one case. | we report a pediatric patient of lyme disease in taiwan, confirmed by laboratory tests. an 8-year-old overseas chinese girl from new jersey, usa, visited our dermatological clinic with joint pain and multiple expanding annular erythema rashes (measured up to 17x10 cm) for three days. lyme disease was diagnosed by the presence of the antibody against borrelia burgdorferi. the skin lesions and arthralgia were resolved after amoxicillin treatment, and she got well in the following one year. this pr ... | 2002 | 12148968 |
| an ospa-based genospecies identification of lyme disease spirochetes (borrelia burgdorferi) isolated in taiwan. | to further identify the genospecies of lyme disease spirochetes (borrelia burgdorferi) isolated in taiwan, we analyzed the genomic identities of these taiwan isolates (twkm1-7) by genospecies-specific polymerase chain reaction (pcr) assay, restriction fragment length polymorphism (rflp) analysis, and gene sequencing based on the ospa gene sequences of b. burgdorferi sensu lato. pcr analysis indicates that all of these taiwan isolates were genetically related to the genospecies of b. burgdorferi ... | 2002 | 12201600 |
