vectorial capacity of north american ixodes ticks. | ixodes dammini, the vector of lyme disease and babesiosis, is distributed in various locations in the northeastern quadrant of the united states and nearby canada. the life cycle of this tick, which includes larval, nymphal, and adult stages, spans at least two years. the tick over-winters between larval and nymphal feeding. horizontal transmission of pathogens is facilitated by a feeding pattern in which both the larval and nymphal stages feed on the white-footed mouse, peromyscus leucopus, and ... | 1984 | 6516453 |
antibody response of the mouse reservoir of borrelia burgdorferi in nature. | to determine whether the white-footed mouse reservoir host (peromyscus leucopus) of the agent of lyme disease (borrelia burgdorferi) naturally mounts an immune response against the full range of antigens expressed by this zoonotic pathogen, we analyzed the pattern of immunoreactivity of these rodents at sites in which the intensity of transmission differs. although the incidence of seroconversion within the reservoir population relates proportionally to the density of subadult deer ticks (ixodes ... | 1995 | 7622226 |
detection of borrelia burgdorferi dna in museum specimens of peromyscus leucopus. | to determine whether borrelia burgdorferi was enzootic within the united states at the beginning of the 20th century, ear skin samples taken from museum specimens of the white-footed mouse (peromyscus leucopus) were examined for evidence of spirochetal dna. in total, 280 samples from mice collected between 1870 and 1919 were analyzed by a nested polymerase chain reaction protocol. of these, 2 specimens from the vicinity of dennis, massachusetts, during 1894 were reproducibly positive for b. burg ... | 1994 | 7930700 |
cosegregation of a novel bartonella species with borrelia burgdorferi and babesia microti in peromyscus leucopus. | during surveillance for various tickborne pathogens in the upper midwest during the summer and early fall of 1995, a bartonella-like agent was detected in the blood of mice that were concurrently infected with borrelia burgdorferi or babesia microti (or both). the organism was isolated in pure culture after inoculation of blood from wild-caught mice into c.b-17 scid/scid mice. phylogenetic analysis of the 16s rrna and the citrate synthase genes showed that the novel bartonella species and a bart ... | 1998 | 9466529 |
helicobacter bilis/helicobacter rodentium co-infection associated with diarrhea in a colony of scid mice. | an outbreak of diarrhea spanning 3 months occurred in a breeding colony of scid/trp53 knockout mice. approximately a third of the 150 mice were clinically affected, with signs ranging from mucoid or watery diarrhea to severe hemorrhagic diarrhea with mortality. helicobacter bilis and the newly recognized urease-negative organism h. rodentium were isolated from microaerobic culture of feces or cecal specimens from affected mice. dual infection with h. bilis and h. rodentium were confirmed by cult ... | 1998 | 10090057 |
physicians caught in the web. thanks to internet, doc disciplinary data now just a mouse click away. | the states are busy making more information available to the public about disciplinary actions taken against doctors. streamlining the process is the internet. most states now post data on web sites detailing actions taken against docs for unethical, questionable or criminal conduct. the next target for those seeking more information on their healthcare providers: the national practitioner data bank. one lawmaker promises legislation that would open it to the public. | 2000 | 11186522 |
enzootic transmission of deer tick virus in new england and wisconsin sites. | to determine whether rodents that are intensely exposed to the deer tick-transmitted agents of lyme disease, human granulocytic ehrlichiosis, and human babesiosis are also exposed to deer tick virus (dtv), we assayed serum samples from white-footed mice (peromyscus leucopus) and meadow voles (microtus pennsylvanicus) in sites densely infested by deer ticks. to conduct serosurveys, we developed an enzyme-linked immunosorbent assay (elisa) and western blot assay by cloning, expressing, and purifyi ... | 2000 | 11357992 |
