title: Gnathostoma procyonis from south Georgia and north Florida raccoons.
abstract: From 2004 to 2006, 511 raccoons collected by the United States Department of Agriculture Wildlife Services as part of a study to evaluate the effects of mesomammalian predator removal on bobwhite-quail reproduction, were examined for the presence of Gnathostoma procyonis, a nematode that parasitizes the stomach of its definitive host, the raccoon. One hundred forty-one raccoons (27.6%) contained G. procyonis, with males being equally infected (27.5%) as females (27.8%). Mean intensity did not differ significantly between sexes (males-mean = 2.88, range 1-17; females-mean = 2.78, range 1-10) or between collection sites. A significant seasonal prevalence of G. procyonis was noted with a peak in March (43.3%, n = 120) and a minimum in September (5.4%, n = 37). Both collection sites exhibited significant seasonal decreases in G. procyonis, but were not significantly different from each other. There was no cumulative seasonal pattern in mean intensity of G. procyonis, and no seasonal pattern at either collection site. Host weight was not related to either G. procyonis prevalence or mean intensity. Host removal did not have an apparent effect on prevalence or mean intensity of G. procyonis.
