title: Rhodococcus equi in fecal and environmental samples from Kansas horse farms.
abstract: Horse farms in Kansas were surveyed for the incidence of Rhodococcus equi. Fecal specimens and soil or cobweb samples were collected from each farm and cultured on selective media. One control farm (with no history of R. equi infection), one farm which had an outbreak 3 and 4 years previously and 2 farms which had R. equi-infected foals that season were surveyed. In addition, fecal samples from 21 horses hospitalized in the Kansas State University Veterinary Hospital were cultured. There was no significant difference in the incidence of R. equi in fecal samples from the 2 farms with recent disease problems. The farm with a history of disease had a significantly higher percentage of positive fecal cultures than the 2 farms with a more recent history of disease. Neither ration composition nor sex of the horses appeared to affect the fecal culture results. Fecal samples from 2 birds on 1 farm were positive for R. equi.
