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 ...200718047394
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 ...201120846016
antibodies to granulocytic ehrlichiae in white-footed and cotton mice in eastern united states.serum samples, collected from peromyscus leucopus (white-footed mouse) or peromyscus gossypinus (cotton mouse) during 1987 through 1990 in florida, georgia, maryland, mississippi, and north carolina (usa), and in 1997 in southern connecticut were analyzed by indirect fluorescent antibody (ifa) staining methods or western blot procedures for antibodies to granulocytic ehrlichiae. of the 82 sera from white-footed mice in connecticut tested by ifa methods with either the bds or nch-1 strain of the ...199910231752
