| comparison of host-feeding patterns between anopheles quadrimaculatus sibling species a and b. | bloodmeal sources for sympatric species a and b of anopheles quadrimaculatus in an area of mississippi were identified using an indirect enzyme-linked immunosorbent assay. females had fed only on 6 species of mammals including dog/fox, pig, opossum, raccoon, cottontail rabbit and white-tailed deer. the latter species was the predominant host, representing 96.7 and 89.5% of the bloodmeals taken by species a and b, respectively. no marked difference in feeding patterns was found. | 1991 | 1791465 |
| 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 |
| white-tailed deer as a potential reservoir of ehrlichia spp. | we determined the antibody prevalence to ehrlichia spp., in white-tailed deer (odocoileus virginianus) and the geographic distribution of seropositive animals in 84 counties in alabama, arkansas, florida, georgia, illinois, kentucky, louisiana, maryland, massachusetts, mississippi, missouri, north carolina, south carolina, tennessee, texas, virginia, and west virginia (usa). using an indirect fluorescent antibody test we detected antibodies (> or = 1:128) to this bacterium in 544 (43%) of 1269 d ... | 1994 | 8028099 |
| culture and serologic survey for mycobacterium avium subsp. paratuberculosis infection among southeastern white-tailed deer (odocoileus virginianus). | from july 1998 through october 2002, radiometric culture (ileocecal lymph node, mesenteric lymph node, and feces) and serologic testing by enzyme-linked immunosorbent assay (elisa) were used to survey white-tailed deer (odocoilens virgianus) from the soutlheastern united states for infection by mycobacterium avium subsp. paratuberculosis (mptb), the causative agent of paratuberculosis (johne's disease). mycobacterium avium subsp. paratuberculosis was isolated from the ileocecal lymph node of one ... | 2004 | 15362831 |
| influence of snowfall on blood lead levels of free-flying bald eagles (haliaeetus leucocephalus) in the upper mississippi river valley. | lead poisoning of scavenging raptors occurs primarily via consumption of game animal carcasses containing lead, which peaks during fall firearm hunting seasons. we hypothesized that snowfall would mitigate exposure by concealing carcasses. we categorized blood lead level (bll) for a subsample of bald eagles (haliaeetus leucocephalus) from the upper mississippi river valley and described bll with respect to age, sex, and snowfall. we captured bald eagles overwintering in the upper mississippi riv ... | 2017 | 28753412 |
| the prevalence of cryptosporidium and giardia spp. in fecal samples from free-ranging white-tailed deer (odocoileus virginianus) in the southeastern united states. | the prevalence of cryptosporidium sp. and giardia sp. in fecal samples collected from free-ranging white-tailed deer (odocoileus virginianus) was determined for animals in virginia and mississippi. the 34 virginia samples came from young of the year (< or =6 months of age) presented to the wildlife center of virginia, and the 360 mississippi samples came from animals (> or =6 months of age) collected from 42 different sites across the state. cryptosporidial oocysts were detected in 8.8% and 5.0% ... | 1999 | 9925215 |
| tick-borne disease agents in various wildlife from mississippi. | because tick-borne diseases are becoming increasingly important throughout the world, monitoring their causative agents in wildlife may serve as a useful indicator of potential human exposure. we assessed the presence of known and putative zoonotic, tick-borne agents in four wildlife species in mississippi. animals were tested for exposure to or infection with ehrlichia chaffeensis, ehrlichia ewingii, borrelia lonestari, rickettsia spp., anaplasma phagocytophilum, and francisella tularensis. who ... | 2011 | 20846016 |
| habitat factors influencing distributions of anaplasma phagocytophilum and ehrlichia chaffeensis in the mississippi alluvial valley. | human monocytotropic ehrlichiosis (hme), caused by the bacterium ehrlichia chaffeensis, and human granulocytic anaplasmosis (hga), caused by the bacterium anaplasma phagocytophilum, are two emerging tick-borne zoonoses of concern. factors influencing geographic distributions of these pathogens are not fully understood, especially at varying spatial extents (regional versus landscape) and resolutions (counties versus smaller land units). we used logistic regression to compare influences of physic ... | 2007 | 18047394 |
| molecular and biologic characteristics of toxoplasma gondii isolates from wildlife in the united states. | toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered more virulent in outbred mice and have been isolated predominantly from clinical cases of human toxoplasmosis, whereas types ii and iii isolates are considered less virulent for mice and are found in humans and food animals. little is known of genotypes of t. gondii isolates from wild animals. in the present report, genotypes of isolates of t. gondii from wildlife in the united states are described. ... | 2004 | 15040668 |
| distribution of spiculopteragia pursglovei and s. odocoilei (nematoda: trichostrongyloidea) from white-tailed deer (odocoileus virginianus) in the southeastern united states. | the distribution of spiculopteragia pursglovei (= apteragia pursglovei) and s. odocoilei (= a. odocoilei) in 12 southeastern states was determined after examining the abomasal contents of 1,369 white-tailed deer over an 8-yr period. spiculopteragia odocoilei was encountered with much greater frequency than s. pursglovei except in some areas along the mississippi river drainage and the coasts of north carolina and south carolina. in instances where both parasites were found in a population, one u ... | 1988 | 3357127 |
| an update on the distribution of parelaphostrongylus tenuis in the southeastern united states. | an update is presented on the distribution of the meningeal worm (parelaphostrongylus tenuis) of white-tailed deer (odocoileus virginianus) in the southeastern united states. the parasite is widely distributed and common in all or much of arkansas, kentucky, louisiana, maryland, north carolina, tennessee, virginia and west virginia. it is also common in the northern half of alabama and georgia. in contrast, it is rare or absent along the atlantic and gulf coastal plains of alabama, georgia, miss ... | 1991 | 2067060 |
| apteragia pursglovei sp. n. (trichostrongyloidea: trichostrongylidae) from the white-tailed deer, odocoileus virginianus. | two species of apteragia were found in white-tailed deer (odocoileus virginianus) from 152 counties in 13 southeastern states. specimens previously reported as skrjabinagia odocoilei were reidentified as belonging to 2 similar species of the genus apteragia, a. odocoilei, and a. pursglovei sp. n. apteragia pursglovei sp. n. is differentiated primarily by the length, conformation, and degree of sclerotization of the spicules. of the 824 deer, a. odocoilei occurred in 76.5%, a. pursglovei in 13.8% ... | 1979 | 448613 |
| soil resources area affects herbivore health. | soil productivity effects nutritive quality of food plants, growth of humans and animals, and reproductive health of domestic animals. game-range surveys sometimes poorly explained variations in wildlife populations, but classification of survey data by major soil types improved effectiveness. our study evaluates possible health effects of lower condition and reproductive rates for wild populations of odocoileus virginianus zimmerman (white-tailed deer) in some physiographic regions of mississip ... | 2011 | 21776246 |
