Helminth species diversity and biology in the bobcat, Lynx rufus (Schreber), from Nebraska.
Cestodes of 4 species and nematodes of 9 species were collected from 75 bobcats, Lynx rufus (Schreber), in Nebraska from 1977 to 1979. Of these 75, 11 were trapped from 6 border counties in 3 border states: South Dakota, 7 carcasses/3 counties; Kansas, 3/2; and Wyoming, 1/1. Helminths recovered included: Mesocestoides corti Hoeppli, 1925 (15% prevalence), Taenia rileyi Loewen, 1929 (67%), Taenia pisiformis (Bloch, 1780) Gmelin, 1790 (27%), Taenia macrocystis (Diesing, 1850) Lühe, 1910 (19%), Physaloptera praeputialis von Linstow, 1889 (55%), Physaloptera rara Hall and Wigdor, 1918 (32%), Toxascaris leonina (von Linstow, 1902) Leiper, 1907 (31%), Toxocara cati (Schrank, 1780) (39%), Ancylostoma tubaeforme (Zeder, 1800) von Linstow, 1885 (5%), Pterygodermatites (Multipectines) cahirensis (Jägerskiöld, 1909) Quentin, 1969 (1%), Vogeloides felis (Vogel, 1928) Davtian, 1933 (7%), Cylicospirura felineus (Chandler, 1925) Sandground, 1932 (12%), and Capillaria aerophila (Creplin, 1839) (4%). One bobcat was not infected; 74 had 1 to 7 species (means = 3). Simpson's index for helminth species was moderately low (0.12), indicating a relatively diverse helminth fauna. Mean levels of infection between prominent species pairs and within each species were compared with bobcat sex and age differences using Student's t-test. Mean intensity of Physaloptera praeputialis was significantly (P less than 0.01) greater than that of Toxocara cati; mean intensity of Mesocestoides corti was significantly (P less than 0.01) greater than that of all other prominent species. No significant intensity differences were indicated among bobcat sex and age categories. G-tests computed for prevalence of prominent species with bobcat age indicated no significance.(ABSTRACT TRUNCATED AT 250 WORDS)
