Exotic North American raccoons live on base, and these animals can harbor other ascarids
Life cycles of strongyles and ascarids
Furthermore, pups and kittens may have patent intestinal infections as early as the first 2 (hookworms) to 3 (ascarids

Toxocara cati is the most common feline roundworm, or ascarid

However, morphologic characteristics of nematodes in this study were more consistent with ascarids
. There is a bovine roundworm (Toxocara viturolum), but it is uncommon in the United States.
Results of necropsy and fecal examinations found low levels of internal parasitism, with cestodes and ascarids
identified as the most prevalent endoparasites.
procyonis eggs have a low thermal death point at [less than or equal to] 62[degrees]C, similar to that reported for other ascarids
In 2006 and 2007, nine ascarids
(>3 inches) were collected from the feces of an unrecorded number of raccoons admitted to a rehabilitation center in northern Florida.
