helical mycoplasmas (spiroplasmas) from ixodes ticks.	a new spiroplasma isolated from ixodes pacificus collected in oregon was serologically and morphologically distinct from known spiroplasmas. the new spiroplasma could also be isolated in tick cell cultures. discovery of a new fastidious mycoplasma in ticks offers opportunities to explore the possible role of these agents in human and animal diseases.	1981	7233197
tick paralysis in a western harvest mouse.	an engorging female ixodes pacificus was observed on a western harvest mouse (reithrodontomys megalotis) in humboldt county, california. the mouse demonstrated a flaccid paraplegia, but it appeared to recover fully after the tick was removed.	1980	7431519
cases of lyme disease in the united states: locations correlated with distribution of ixodes dammini.	lyme disease, defined by erythema chronicum migrans and sometimes followed by neurologic, cardiac, or joint involvement, is known to have affected 512 patients in the united states. the disease seems to occur in three distinct foci: along the northeastern coast, in wisconsin, and in california and oregon, a distribution that correlates closely with that of ixodes dammini in the first two areas and with ixodes pacificus in the last. the implicated tick, saved by six patients in the northeast, was ...	1979	496106

isolation of a spotted fever group rickettsia from the pacific coast tick, ixodes pacificus, in oregon.	a rickettsia of the spotted fever group was isolated on three occasions from ixodes pacificus in western oregon. these isolations, and additional evidence furnished by complement fixation tests on guinea pigs inoculated with other oregon ticks of this species, indicate that the association of this rickettsia with the pacific coast tick may be widespread. this is the first isolation of a spotted fever group rickettsia from i. pacificus. because the oregon isolates are mildly virulent for guinea p ...	1976	937637

climate change and infectious diseases in north america: the road ahead.	global climate change is inevitable--the combustion of fossil fuels has resulted in a buildup of greenhouse gases within the atmosphere, causing unprecedented changes to the earth's climate. the fourth assessment report of the intergovernmental panel on climate change suggests that north america will experience marked changes in weather patterns in coming decades, including warmer temperatures and increased rainfall, summertime droughts and extreme weather events (e.g., tornadoes and hurricanes) ...	0	18332386
arthropod-borne disease in canada: a clinician's perspective from the 'cold zone'.	arthropod-borne diseases do not occur commonly in canada. nevertheless, canadians run the risk of contracting certain infections within the country during arthropod season, as well as when travelling abroad. therefore, it is important that clinicians are aware of the possible occurrence of arthropod-borne diseases, and consider them in their differential diagnoses. the present review is divided into two sections: arthropod-borne diseases or disease agents documented in canada, and imported arthr ...	0	20177520
update on tick-borne rickettsioses around the world: a geographic approach.	tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus rickettsia. these zoonoses are among the oldest known vector-borne diseases. however, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. several species of tick-borne rickettsiae that wer ...	0	24092850
multiplex sybr® green-real time pcr (qpcr) assay for the detection and differentiation of bartonella henselae and bartonella clarridgeiae in cats.	a novel sybr® green-real time polymerase chain reaction (qpcr) was developed to detect two bartonella species, b. henselae and b. clarridgeiae, directly from blood samples. the test was used in blood samples obtained from cats living in animal shelters in southern brazil. results were compared with those obtained by conventional pcr targeting bartonella spp. among the 47 samples analyzed, eight were positive using the conventional pcr and 12 were positive using qpcr. importantly, the new qpcr de ...	0	24626408
