Prevalence of Soboliphyme baturini in marten (Martes americana) populations from three regions of Alaska, 1990-1998

Marten (Martes americana) carcasses were collected from trappers in three regions of Alaska. Stomachs were examined for the nematode parasite Soboliphyme baturini. Both prevalence and intensity of infection exhibited an increase from north to south. Prevalence was higher in adults (compared with juveniles) from the two mainland study areas. Prevalences in these two age classes were similar for the southeastern region. There were no sex-specific differences in prevalence. No pathologic changes were observed in the gastrointestinal tract. Impact of the parasite on either individual animals or populations was not detected.
