epidemiology of potomac horse fever: an investigation into the possible role of non-equine mammals.a serological study of antibodies to ehrlichia risticii was carried out on 10 species of wild and domestic mammals found on or near 21 horse farms in an area of the usa in which potomac horse fever is endemic. no antibodies were found in 133 peridomestic rodents (norway rats and house mice), nor in 108 wild rodents (white-footed mice and meadow voles) captured on farms. three of the six domestic animal species examined, cats, pigs and a goat, showed serological evidence of exposure to e risticii ...19892773237
