absence of transplacental transmission of lyme disease spirochetes from reservoir mice (peromyscus leucopus) to their offspring.lyme disease spirochetes (borrelia burgdorferi) are naturally maintained in an enzootic cycle mainly by vector ticks (ixodes dammini) infesting white-footed mice (peromyscus leucopus). suggestions that mice may become infected without exposure to ticks prompted a study to evaluate whether mice could transmit spirochetes transplacentally to their offspring. mice were live-captured in two massachusetts sites where lyme disease spirochetes are intensely enzootic. pregnant females were housed separa ...19911869842

[parasite fauna of red foxes in berlin (west)].the infestation with ecto- and endoparasites of red foxes in berlin (west) was investigated. as shown by post mortems of 100 animals (47 males and 53 females), none of them was found to be free of parasites. with regard to ectoparasites, 3 species of ixodes ticks, 7 flea species, one species of biting lice and mite species were demonstrated. the sarcoptic mange is often inducing the death of the foxes and is considered to be a limiting factor of the population increment. concerning endoparasites ...19911872791
diagnosis of lyme borreliosis by an enzyme immunoassay detecting immunoglobulin g reactive to purified borrelia burgdorferi cell enzyme immunoassay (eia) developed for the diagnosis of lyme borreliosis was tested for its specificity and sensitivity in detecting igg antibodies in patients at various stages of the disease. the eia is based on a detergent extract of borrelia burgdorferi which contains 12 proteins of defined molecular weights from borrelia burgdorferi. the assay showed a specificity of 100% in control sera from 64 healthy individuals, using a cut-off optical density value of 0.13 (means +2- 3 sd). the sens ...19911874248
susceptibility of iron-loaded borrelia burgdorferi to killing by hydrogen peroxide and human polymorphonuclear leucocytes.borrelia burgdorferi grew more slowly in iron-depleted than in iron-sufficient media. the addition of increasing concentrations of iron stimulated borrelial growth and resulted in the intracellular accumulation of this element. compared with iron-starved borrelia, iron-enriched organisms showed enhanced sensitivity to hydrogen peroxide. intracellular iron-content did not, however, influence susceptibility to killing by human polymorphonuclear leucocytes [corrected].19911874405

lyme borreliosis: detecting the great imitator.lyme disease is a common inflammatory disease of north america. it is caused by the spirochetal bacterium borrelia burgdorferi, which is transmitted by the bite of a small tick, ixodes dammini. the disease is inconsistent in its manifestation, mimicking a wide variety of maladies, many of which are noninfectious. currently, there is no practical means for detection of the presence of the organism, and serologic studies offer the best diagnostic aid. high titers of either immunoglobulin g (igg) o ...19911874654
wood rats and kangaroo rats: potential reservoirs of the lyme disease spirochete in california.the etiologic agent of lyme disease, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, was isolated repeatedly from dusky-footed wood rats, neotoma fuscipes baird, and california kangaroo rats, dipodomys californicus merriam, in northern california. all animals were collected in a region endemic for lyme disease but for which the natural reservoir of b. burgdorferi was unknown. similar attempts to isolate spirochetes from lizards, other species of rodents, jack rabbits, and deer ...19911875357
detection of borrelia burgdorferi in cerebrospinal fluid by the polymerase chain reaction.the polymerase chain reaction (pcr) was used to amplify specific dna sequences from different clinical isolates of borrelia burgdorferi and from cerebrospinal fluid (csf) of two patients with lyme disease of the central nervous system. the amplification products were separated by polyacrylamide gel electrophoresis and visualised by ethidium bromide staining. the definitive identification of amplified dna as a part of the b. burgdorferi flagellin gene was achieved by hybridisation to a 40-base ol ...19911875398
