This study characterized bot fly (Cuterebra fontinella) parasitism in a local population of white-footed mice (Peromyscus leucopus) in Cincinnati, Ohio. The researchers found that the prevalence and intensity of parasitism varied significantly between study sites, with one site having the highest levels. Infected mice were found to be in better physical condition than uninfected mice. While no effects of parasitism were seen for sex, age, or reproductive activity, spatial factors like habitat characteristics and landscape features likely influence patterns of bot fly infection in this host population.
