| prevalence of borrelia burgdorferi in white-footed mice and ixodes dammini at fort mccoy, wis. | borrelia burgdorferi, the causative agent of lyme disease, was isolated from 15 of 17 white-footed mice (peromyscus leucopus) and 54 of 82 subadult ixodes dammini from fort mccoy, wis. of the 47 isolates tested, all reacted in indirect fluorescent-antibody tests with monoclonal antibodies directed against a surface protein of b. burgdorferi (approximate molecular weight, 31,000) and flagellins that are common to all borrelia species. indirect fluorescent-antibody reactions were variable when an ... | 1987 | 3305566 |
| seroepidemiologic survey of borrelia burgdorferi exposure of dairy cattle in wisconsin. | an elisa, using purified flagellin of borrelia burgdorferi as the solid-phase antigen, was used to measure antibody concentrations to b burgdorferi in dairy cattle in wisconsin. serum obtained from 5,060 cows in 160 randomly selected herds in the state were tested. serum from an additional 2,600 cattle in barron county, wis, a county with a high annual incidence of b burgdorferi infections in human beings, was also tested. only 7% of the cows that were tested, but 66% of the herds that were test ... | 1994 | 7802388 |
| lyme disease spirochetes in ticks collected from birds in midwestern united states. | in a tick-spirochete survey conducted from all 1989 through fall 1992 in north-western wisconsin, 4,256 birds (composed of 91 species) were examined for ticks. infestations were recorded for 400 birds (composed of 30 species). of 1,184 ticks taken from 335 birds (composed of 26 species), 60 (5%) haemaphysalis leporispalustris (packard) from 8 species of birds were infected with the lyme disease spirochete. borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner. similar surveys conduct ... | 1996 | 8667384 |
| borrelia burgdorferi-infected ixodes scapularis (acari: ixodidae) and peromyscus leucopus in northeastern wisconsin. | populations of the blacklegged tick, ixodes scapularis say, are established in western and central wisconsin in the upper midwestern united states, but appear to be expanding geographically there. here, we report a previously unknown population in northeastern wisconsin. questing i. scapularis nymphs and adults were collected by flagging vegetation from a riverine site in marinette county, wisconsin, in spring of 1993 and 1994. dissection and culture of tick guts in modified barbour-stoenner-kel ... | 1996 | 8906923 |
| coinfection with babesia microti and borrelia burgdorferi in a western wisconsin resident. | a 68-year-old woman, who had not traveled outside of western wisconsin, was hospitalized after 4 weeks of chills, fevers, myalgias, neuralgias in her right arm, and pain in the right upper quadrant of her abdomen. physical examination revealed hepatosplenomegaly, and laboratory studies showed anemia, thrombocytopenia, increased aspartate transaminase level, and microscopic hematuria. wright's stain of a blood smear revealed intraerythrocytic organisms consistent with babesia species. a polymeras ... | 1998 | 9559037 |
| ixodes scapularis (acari: ixodidae): abundance and rate of infection with borrelia burgdorferi in four state parks in wisconsin. | four state parks located in lyme disease endemic regions of wisconsin were surveyed for the presence of ixodes scapularis say during may and june of 1998 by drag sampling along hiking trails. nymphal abundance varied between parks, with the average number of nymphs encountered in 1 h ranging from 6.2 +/- 3.8-47.1 +/- 36.3 (mean +/- sd). questing nymphs were tested for the presence of borrelia burgdorferi by culture in bsk medium and 7-12% was found to be infected. the average risk of encounterin ... | 2001 | 11268688 |
| canine surveillance system for lyme borreliosis in wisconsin and northern illinois: geographic distribution and risk factor analysis. | a seroprevalence survey for borrelia burgdorferi was conducted among the healthy canine pet population in selected counties of wisconsin and northern illinois to determine the distribution of lyme disease and associated risk factors. information obtained for each dog included place of residence, lyme disease vaccination status, history of travel and tick exposure, signalment, and medical history. serum samples were screened by enzyme-linked immunosorbent assay and confirmed by an immunoblot proc ... | 2001 | 11716112 |
| presence of borrelia burgdorferi (spirochaetales: spirochaetaceae) in southern kettle moraine state forest, wisconsin, and characterization of strain w97f51. | lyme disease, caused by borrelia burgdorferi johnson, schmidt, hyde, steigerwalt & brenner; babesiosis, caused by babesia microti franca; and human granulocytic ehrlichiosis, caused by anaplasma phagocytophilum bakken & dumler have been reported in wisconsin, mainly in the endemic areas of the northwestern part of the state. people exposed to blacklegged ticks, ixodes scapularis say, from this region can potentially contract one or all of these diseases concurrently. within the past several year ... | 2005 | 15962800 |
| infection and co-infection rates of anaplasma phagocytophilum variants, babesia spp., borrelia burgdorferi, and the rickettsial endosymbiont in ixodes scapularis (acari: ixodidae) from sites in indiana, maine, pennsylvania, and wisconsin. | in total, 394 questing adult blacklegged ticks, ixodes scapularis say (acari: ixodidae), collected at four sites were analyzed by polymerase chain reaction (pcr) for five microbial species: anaplasma phagocytophilum, babesia microti, babesia odocoilei, borrelia burgdorferi, and the rickettsial i. scapularis endosymbiont. identities of genetic variants of a. phagocytophilum were determined by sequencing a portion of the 16s dna. in 55% of infected ticks (193/351), a single agent was detected. in ... | 2008 | 18402145 |
| surveillance for lyme disease--united states, 1992-2006. | lyme disease is a multisystem disease that occurs in north america, europe, and asia. in the united states, the etiologic agent is borrelia burgdorferi sensu stricto, a spirochete transmitted to humans by infected ixodes scapularis and i. pacificus ticks. the majority of patients with lyme disease develop a characteristic rash, erythema migrans (em), accompanied by symptoms of fever, malaise, fatigue, headache, myalgia, or arthralgia. other manifestations of infection can include arthritis, card ... | 2008 | 18830214 |
