| surveillance of lyme disease in the united states, 1982. | lyme disease is a tick-borne illness that has been reported from three regions in the united states--the northeast, midwest, and west--which correspond to the distribution of the recognized vectors of the disease, ixodes dammini and ixodes pacificus. in 1982, a surveillance system designed to define the morbidity and geographic distribution for lyme disease by using a clinical case definition received information on 491 definite cases and 38 probable cases. of the definite cases, 489 were acquir ... | 1985 | 3998509 |
| reported distribution of ixodes scapularis and ixodes pacificus (acari: ixodidae) in the united states. | lyme disease, caused by infection with borrelia burgdorferi, is the most frequently reported arthropod-borne disease in the united states. to develop a national map of the distribution of the vectors of b. burgdorferi to humans (ixodes scapularis say and ixodes pacificus cooley & kohls ticks), we sent questionnaires to acarologists, health officials, and lyme disease researchers; surveyed the 1966-1996 medline data base; and reviewed 1907-1995 national tick collection data. tick collection metho ... | 1998 | 9775584 |
| distribution of borreliae among ticks collected from eastern states. | lyme disease is the most commonly reported vector-borne disease in the united states and is transmitted by borrelia burgdorferi-infected ixodes species. the disease is typically characterized by an erythema migrans (em) rash at the site of tick feeding. em rashes have also been associated with feeding by amblyomma americanum ticks despite evidence suggesting that they are incompetent vectors for lyme disease. in 1996, a borrelia organism only recently cultivated in the laboratory was described i ... | 2005 | 16417434 |
| detection of babesia and anaplasma species in rabbits from texas and georgia, usa. | rabbits have been shown to harbor a suite of zoonotic organisms, including a babesia species, borrelia burgdorferi, and anaplasma phagocytophilum. in this study, we conducted a molecular survey for various tick-borne pathogens in three species of rabbits from texas and georgia. of 18 black-tailed jackrabbits (lepus californicus) tested from texas, six (28%) were polymerase chain reaction (pcr) positive for babesia, and nucleotide sequencing revealed two distinct species or strains. two jackrabbi ... | 2006 | 16584322 |
| prospective health assessment of fort campbell, kentucky patrons bitten by ticks. | amblyomma americanum is an aggressive human-biting tick that transmits several known human pathogens and is associated with a lyme disease-like illness of unknown etiology. to determine the frequency, distinguishing clinical characteristics, and etiology ofa. americanum-associated illness and identify associated risk factors, a prospective study of adult tick-bite victims was conducted at fort campbell from 2005-2007. forty-two participants submitted ticks, none of which contained borrelia lones ... | 2009 | 19485114 |
| using exploratory data analysis to identify and predict patterns of human lyme disease case clustering within a multistate region, 2010-2014. | lyme disease is the most commonly reported vectorborne disease in the united states. the objective of our study was to identify patterns of lyme disease reporting after multistate inclusion to mitigate potential border effects. county-level human lyme disease surveillance data were obtained from kentucky, maryland, ohio, pennsylvania, virginia, and west virginia state health departments. rate smoothing and local moran's i was performed to identify clusters of reporting activity and identify spat ... | 2017 | 28137676 |
| coma falsely attributed to lyme disease. | neuroborreliosis has very low prevalence in kentucky and coma due to lyme disease is uncommon in north america. a patient diagnosed with lyme disease in kentucky, based on coma, typical inflammatory changes on brain imaging, and a positive elisa resulted in an erroneous clinical impression. diagnosis should have been confirmed by a positive result on western blot, polymerase chain reaction (pcr), or real-time polymerase chain reaction (rt-pcr) testing. physicians must apply careful consideration ... | 2008 | 18777697 |
| the epidemiology of lyme disease in kentucky, 1985-1990. | lyme disease has become the most common vector-borne disease in the united states. to assess the extent of the disease in kentucky, all case reports were reviewed for 1985-1990. a total of 51 cases met the current case definition. epidemiologic features were similar to those reported nationally. although the recognized tick vectors for lyme disease have still not been identified in kentucky, physicians should educate their patients on the risk of lyme disease and measures to prevent tick bites. ... | 1991 | 1856584 |

| borrelia burgdorferi in small mammal reservoirs in kentucky, a traditionally non-endemic state for lyme disease. | the incidence of tick-borne zoonoses such as lyme disease has steadily increased in the southeastern united states. southeastern states accounted for 1500 of over 28,000 confirmed cases of lyme disease reported in the united states during 2015. borrelia burgdorferi, the etiologic agent of lyme disease, is maintained in small mammal reservoirs and vectored to new hosts by ixodid ticks. this study examined ecological relationships of the b. burgdorferi/vector/reservoir system in order to understan ... | 2018 | 29417273 |
