antibodies to borrelia burgdorferi in rodents in the eastern and southern united states.serologic studies were conducted to determine whether white-footed mice (peromyscus leucopus) and cotton mice (peromyscus gossypinus) contained serum antibodies to borrelia burgdorferi, the causative agent of lyme borreliosis. enzyme-linked immunosorbent assays detected antibodies to this spirochete in 35.7 and 27.3% of 56 p. leucopus and 535 p. gossypinus serum samples, respectively, collected in connecticut, north carolina, south carolina, georgia, florida, alabama, and mississippi. antibody t ...19921624561
etiologic agent of lyme disease, borrelia burgdorferi, detected in ticks (acari: ixodidae) collected at a focus in alabama.the study was conducted at sites of known transmission of borrelia burgdorferi in east central alabama. the objectives were to determine species of ticks present at these sites, their host associations, and species of ticks and small mammals naturally infected with b. burgdorferi. a total of 451 hosts were examined for ticks, including cotton mice, peromyscus gossypinus (le conte); cotton rats, sigmodon hispidus say & ord; southern short-tailed shrews, blarina carolinensis (bachman); house mice, ...19911941933
relative utilization of reptiles and rodents as hosts by immature ixodes scapularis (acari: ixodidae) in the coastal plain of north carolina, usa.the interaction of immature black-legged ticks, ixodes scapularis, with reptiles and rodents was investigated in various woodland habitats in the coastal plain of north carolina. reptiles were sampled from april 1 to september 30, 1991. no ticks were found on 95 specimens representing 16 species of snakes. ticks were found on 54 (36.7%) of 147 lizards. i. scapularis was the only tick recovered from lizards. some lizards were collected in drift fence traps each month of the study except august. c ...19937628223
natural occurrence and characterization of the lyme disease spirochete, borrelia burgdorferi, in cotton rats (sigmodon hispidus) from georgia and florida.this is the first report of natural infection by borrelia burgdorferi in the cotton rat sigmodon hispidus. nine b. burgdorferi isolates were obtained from ear tissues, urinary bladders, or both, by culturing tissues in bskii medium. the rat from which the si-3 isolate was cultured was from the same site (sapelo island, georgia) as an infected cotton mouse peromyscus gossypinus and ixodes scapularis tick reported previously. the 8 b. burgdorferi isolates from rats in florida included 1 (ai-1) fro ...19957876974
isolation and transmission of the lyme disease spirochete from the southeastern united states.the isolation of the lyme disease spirochete (borrelia burgdorferi) from the southeastern united states is reported. three isolates, two from cotton mice (peromyscus gossypinus) and one from the black-legged tick (ixodes scapularis), were recovered from sapelo island, georgia, in july and september 1991. the spirochetes were characterized by indirect fluorescent antibody assay using a battery of five monoclonal antibodies, by sodium dodecyl sulfate/polyacrylamide gel electrophoresis (sds/page) o ...19938346258
isolation, cultivation, and characterization of borrelia burgdorferi from rodents and ticks in the charleston area of south carolina.twenty-eight borrelia burgdorferi isolates from the charleston, s.c., area are described. this represents the first report and characterization of the lyme disease spirochete from that state. the isolates were obtained from december 1994 through december 1995 from the tick ixodes scapularis, collected from vegetation, and from the rodents peromyscus gossypinus (cotton mouse), neotoma floridana (eastern wood rat), and sigmodon hispidus (cotton rat). all isolates were screened immunologically by i ...200010618074
rodent ectoparasites from two locations in northwestern florida.from feb.-apr. 1999, 19 species of ectoparasitic arthropods (2 sucking lice, 4 fleas, 4 ticks, 2 mesostigmatid mites, 5 chiggers, 2 fur mites) were recovered from 106 rodents belonging to 5 species (cotton mouse, peromyscus gossypinus, n = 64; cotton rat, sigmodon hispidus, n = 23; eastern woodrat, neotoma floridana, n = 9; golden mouse, ochrotomys nuttalli, n = 9; eastern gray squirrel, sciurus carolinensis, n = 1) at tall timbers research station, leon county, florida. during the same period, ...200011217221
genetic heterogeneity of borrelia burgdorferi sensu lato in the southern united states based on restriction fragment length polymorphism and sequence analysis.fifty-six strains of borrelia burgdorferi sensu lato, isolated from ticks and vertebrate animals in missouri, south carolina, georgia, florida, and texas, were identified and characterized by pcr-restriction fragment length polymorphism (rflp) analysis of rrf (5s)-rrl (23s) intergenic spacer amplicons. a total of 241 to 258 bp of intergenic spacers between tandemly duplicated rrf (5s) and rrl (23s) was amplified by pcr. msei and drai restriction fragment polymorphisms were used to analyze these ...200111427560
host associations of ticks parasitizing rodents at borrelia burgdorferi enzootic sites in south carolina.a total of 237 rodents was collected in 4 regions of south carolina from july 1994 through december 1995. eight species were collected, including cotton mouse, hispid cotton rat, eastern woodrat, marsh rice rat, white-footed mouse, eastern harvest mouse, golden mouse, and black rat. of the 1,514 ticks recovered from these hosts, ixodes minor neumann, including larvae, nymphs, and adults, was the most abundant species, representing 54% of the total. only immature stages of other tick species were ...200111780825
an enzootic transmission cycle of lyme borreliosis spirochetes in the southeastern united states.lyme borreliosis, or lyme disease (ld), is a tick-borne zoonotic infection of biomedical significance, caused by borrelia burgdorferi sensu lato (s.l.) spirochetes and transmitted by ixodes species ticks. it usually circulates among wildlife vertebrate reservoirs and vector ticks but may infect humans, causing multisystem problems. in far western and northern north america, the host reservoirs, tick vectors, and genospecies of borrelia are well known but not so in the southern u.s., where there ...200314500917
borrelia species in host-seeking ticks and small mammals in northern florida.the aim of this study was to improve understanding of several factors related to the ecology and environmental risk of borrelia infection in northern florida. small mammals and host-seeking adult ticks were collected at several sites, and specimens were tested for the presence of borrelia species, primarily by pcr amplification. tissues from some vertebrates and ticks were initially cultured in bsk-h medium to isolate spirochetes, but none were recovered. however, comparison of partial flagellin ...200415528699
borrelia carolinensis sp. nov., a new (14th) member of the borrelia burgdorferi sensu lato complex from the southeastern region of the united states.approximately 118 borrelia isolates were cultured from a variety of rodents, birds, and ticks collected in the southern united states. in addition to a highly diverse group of borrelia bissettii strains and a homogenous group of borrelia burgdorferi sensu stricto strains, a group of 16 isolates with unusual characteristics was found. the isolates were cultured from ear biopsy samples of the rodents peromyscus gossypinus and neotoma floridana trapped at five localities in south carolina. a multil ...200919020062
borrelia carolinensis sp. nov., a novel species of the borrelia burgdorferi sensu lato complex isolated from rodents and a tick from the south-eastern usa.a group of 16 isolates with genotypic characteristics different from those of known species of the borrelia burgdorferi sensu lato complex were cultured from ear biopsies of the rodents peromyscus gossypinus and neotoma floridana trapped at five localities in south carolina, usa, and from the tick ixodes minor feeding on n. floridana. multilocus sequence analysis of members of the novel species, involving the 16s rrna gene, the 5s-23s (rrf-rrl) intergenic spacer region and the flagellin, ospa an ...201120305062
