AbstractAn epidemiological survey of 1688 free-ranging raccoons (Procyon lotor) captured on the Japanese main islands of Hokkaido, Honshu and Kyushu was undertaken to determine whether Baylisascaris procyonis, which provokes fatal neurological larva migrans was present; however, the worm was not detected in any of these individuals. A helminthological investigation was carried out on 229 of the captured racoons and the following worms obtained: Toxocara tanuki, Porrocaecum sp., Molineus legerae, Ancylostoma kushimaense, Aonchotheca putorii, Centrorhynchus sp., Centrorhynchus bazaleticus, C. elongatum, Plagiorhynchidae gen sp., Hemiechinosoma sp., Metagonimus takahashii, M. miyatai, Euparyphium sp., Plagiorchis muris, Brachylaima sp., and Taenia hydatigena. These were the first records of Porrocaecum sp., M. miyatai, Brachylaima sp. and T. hydatigena obtained from Japanese feral raccoons. Scanning electron microscopic and/or molecular analyses were performed for both T. tanuki and T. hydatigena as these helminths both have a zoonotic counterpart amongst their families.

Assessment of body condition of free-ranging animals is important when evaluating population health and fitness. The following study used body condition scoring, ultrasound, and dissected physical measurement to assess fat stores in free-ranging raccoons (Procyon lotor). Measurements were taken of subcutaneous fat at interscapular, thoracolumbar, and lumbosacral paraspinal and ventral midline sites. These measurements were examined in relationship to body condition scores and body weight. The ultrasound technique accurately measured the subcutaneous fat of raccoons when compared to dissected physical measurement and yielded data that strongly correlated with both body condition score and body weight, with the ventral midline measurement most strongly correlated. This noninvasive method may be useful in conjunction with body condition score and body weight when assessing the nutritional status of raccoons and potentially other small carnivore species.

Common Parasite

Within Ontario Dracunculus insignis (Leidy 1858) Chandler 1942, a common parasite of raccoon, Procyon lotor (L) (prevalence > 50%), and mink, Mustela vison Schreber (prevalence > 50%), is apparently confined to the southern part of the province. In this area D. insignis was also found in fisher, Martes pennanti (Erxleben); and Dracunculus sp. was found in short-tailed weasel, Mustela erminea (L), muskrat, Ondatra zibethicus (L), and opossum, Didelphis marsupialis (L). The distribution of D. insignis coincides with that of raccoon in Ontario, and it is suggested that raccoon may be a reservoir host for this species and that mink became incorporated into its life cycle secondarily. Dracunculus lutrae Chrichton and Beverley-Burton 1973 of the otter, Lutra canadensis (Schreber), was found across the entire province and, in most areas, the prevalence exceeded 75%. During the trapping season (October–April) larvigerous females were found in 20 (44.4%) of 45 otter infected with D. lutrae in southern Ontario, but were absent from the limbs of 132 infected otter from northern Ontario.

Neuronal Vacuolation

Microscopic vacuolar changes in neuronal perikaryon are described in two free-ranging raccoons ( Procyon lotor) from different geographic locations in the United States. Both animals were negative for rabies and scrapie-associated antigens. Microscopically, lesions were not seen in the neuropil. Neuronal vacuolations have previously been documented in brains of normal animals and in diseases such as rabies and prion-associated encephalopathies. Although experimental transmission of a spongiform mink encephalopathy has been documented in raccoons, a naturally occurring spongiform encephalopathy has not been described in this species. The presence of neuronal vacuolations in the raccoons is novel and requires further investigation to elucidate the mechanism of this phenomenon.
