The stomachs and intestinal tracts of 253 raccoons, Procyon lotor, were examined for helminth parasites. Sixteen species of helminths were found including eight trematodes, two cestodes, five nematodes, and one acanthocephalan. Fourteen of these helminths are new geographic records for the state of Tennessee. Multivariate statistical techniques were used to analyze two-state and multistate character sets. Matrices of correlation among characters were computed and the first three principal components were extracted, accounting for 79.7% and 66.5% of the variation in the respective character sets. Three-dimensional projections of Tennessee's eight geographic localities onto two-state and multistate principal components demonstrated that raccoons in western localities were parasitized most heavily by Atriotaenia procyonis. Mesocestoides variabilis, Gnathostoma procyonis, and Pharyngostomoides procyonis. Parallelorchis diglossus, Euparyphium beaveri. Eurytrema procyonis, Euryhelmis squamala, Molineus barbatus, and Macracanthorhynchus ingens were most common to P. lotor from eastern areas.
对253只北美浣熊（Procyon lotor）的胃和肠道进行了蠕虫寄生虫检查。共发现16种蠕虫，包括8种吸虫、2种绦虫、5种线虫和1种棘头虫。其中14种蠕虫是田纳西州的新地理记录。运用多元统计技术分析两状态和多状态特征集。计算了特征之间的相关矩阵，并提取了前三个主成分，分别占各自特征集变异的79.7%和66.5%。田纳西州八个地理区域在两状态和多状态主成分上的三维投影表明，西部地区的浣熊受原田绦虫（Atriotaenia procyonis）、变异中绦虫（Mesocestoides variabilis）、浣熊颚口线虫（Gnathostoma procyonis）和浣熊咽口线虫（Pharyngostomoides procyonis）的寄生最为严重。双舌并殖吸虫（Parallelorchis diglossus）、比弗狸殖吸虫（Euparyphium beaveri）、浣熊阔盘吸虫（Eurytrema procyonis）、鳞形宽体线虫（Euryhelmis squamala）、巴氏莫尼线虫（Molineus barbatus）和巨棘头虫（Macracanthorhynchus ingens）在东部地区的北美浣熊中最为常见。
