evansi in captive and free-living procyonids in the Eastern Amazon region by blood smear analysis and polymerase chain reaction (PCR).
The biological sample collection and search for parasites in procyonids were authorized by the System for Authorization and Information on Biodiversity from the Chico Mendes Institute for Biodiversity (SISBIO/ICMBIO, protocol 30710-1).
Biologic samples were obtained by convenience from free-living procyonids and animals kept in captivity in wildlife refuges and zoobotanical parks in the states of Amapa and Para (Figure 1).
The procyonids were identified according to the characteristics described in the Neotropical Rainforest Mammals field guide (EMMONS & FEER, 1997) and were classified according to the type of habitat into group A (captive animals) and group B (free-living animals).
Pet dogs, kinkajous and other procyonids, and skunks (host of a related Baylisascaris species) (1), which might be kept as exotic pets, should receive routine veterinary care, including regular dewormings and periodic fecal examinations.
In addition to raccoons, adult BP have been described in a kinkajou from Colombia and in another procyonid, the bushy-tailed olingo (Bassaricyon gabbii) (4).
A similar problem also face the procyonids

There is disagreement about the occurrence of some species, with the following listed: three or four canids [bush dog (Speothos venaticus), maned wolf (Chrysocyon brachyurus), crab-eating fox (Cerdocyon thous), pampas fox (Pseudalopex gymnocercus)], two procyonids
[South American coati (Nasua nasua), crab-eating raccoon (Procyon cancrivorus)], four or five mustelids [tayra (Eira barbara), lesser grison (Galictis cuja) long-tailed otter (Lontra longicaudus), giant otter (Pteronura brasiliensis), hog-nosed skunk (Conepatus chinga)], and, five to eight felids [jaguar (Panthera onca), puma (Puma concolor), ocelot (Leopardus pardalis), margay (L.
