sdetection of vector-borne agents in lone star ticks, amblyomma americanum (acari: ixodidae), from mississippi.	in this study, we evaluated amblyomma americanum (lone star tick) in mississippi for the presence of ehrlichia chaffeensis, causative agent of human monocytic ehrlichiosis; ehrlichia ewingii, causative agent of human and canine granulocytic ehrlichiosis; borrelia lonestari, putative agent of southern tick-associated rash illness; francisella tularensis, the agent of tularemia; and rickettsia spp., particularly r. amblyommii, a suspected pathogen. we collected adult a. americanum from four region ...	2010	20496596
strains of ehrlichia chaffeensis in southern indiana, kentucky, mississippi, and north carolina.	rates of infection of amblyomma americanum (l.) by ehrlichia chaffeensis were compared in 100 ticks collected from sites in each of four states: indiana, north carolina, kentucky, and mississippi. the overall infection rates were similar among sites, ranging from 1 to 4%. because pathogenic differences may exist between e. chaffeensis strains, nested polymerase chain reaction (pcr) amplification of the variable-length pcr target (vlpt), and sequencing of the amplicons were performed to different ...	2009	19960699
geographic distribution of ticks (acari: ixodidae) in iowa with emphasis on ixodes scapularis and their infection with borrelia burgdorferi.	in iowa, public concern regarding lyme disease has increased markedly over the last decade. in response to these concerns, a statewide surveillance program was initiated in 1990 based on ticks received by the department of entomology at iowa state university. ticks were received from health care professionals, state government agencies, and the general public. a total of 5,343 ticks from all 99 iowa counties were identified during the 12 years of this study. dermacentor variabilis was the most n ...	2005	16187889
survey of ticks collected in mississippi for rickettsia, ehrlichia, and borrelia species.	from november 1999 through october 2000, we tested ticks collected from vegetation as well as from deer, dogs, and humans for spotted fever group (sfg) rickettsiae, ehrlichia chaffeensis, and borrelia spp. spirochetes. a total of 149 adult ticks representing four species was collected from 11 collection sites from southwestern to northern mississippi. amblyomma americanum was most commonly collected (n=68), followed by ixodes scapularis (n=53). the bird tick, ixodes brunneus (usually rare), was ...	2003	14714667
effects of season and area on ectoparasites of white-tailed deer (odocoileus virginianus) in mississippi.	nine species of ectoparasites (4 acari, 2 mallophaga, 1 anoplura, 1 diptera, and 1 siphonaptera) were recovered from 126 white-tailed deer collected in northern, central, and southern mississippi. intensity and prevalence of adults of ixodes scapularis and larvae, nymphs, and adults of amblyomma americanum varied significantly over collection periods, but not between host sexes. lipoptena mazamae occurred on deer from only one study area. although individual deer were heavily parasitized by tric ...	1987	3586204

rickettsia-like organisms in ticks and antibodies to spotted fever-group rickettsiae in mammals from northern mississippi.	studies were conducted from april through august during 1974 and 1975 on 30 randomly selected trapping sites in wall doxey state park, holly springs national forest, and 1.6 km south of the park in marshall county, mississippi to provide information on the occurrence of ticks involved in the maintenance and transmission of spotted fever-group rickettsiae in nature. of 365 animals (14 species) collected, 186 (51%) were parasitized by 4,169 ticks. species of ticks collected included: dermacentor v ...	1985	3923212
