    Prevalence of agglutinating antibodies to Toxoplasma gondii and Sarcocystis neurona in beavers (Castor canadensis) from Massachusetts
    Jordan, C. N.; Kaur, T.; Koenen, K.; DeStefano, S.; Zajac, Anne M.; Lindsay, David S. (American Society of Parasitology, 2005-10)
    The present study examined the seroprevalence of Toxoplasma gondii and Sarcocystis neurona in a population of beavers (Castor canadensis) from Massachusetts. Sixty-two blood samples were collected during the field seasons over 3 consecutive years from different animals. Blood was collected onto filter paper and shipped to the Department of Biomedical Sciences, Virginia Tech, Blacksburg, Virginia, for parasite testing. The samples were tested at dilutions of 1:25. 1:50, and]:100 against each parasite antigen by modified agglutination tests to determine whether antibodies to either parasite were present in the blood. Six of 62 samples (10%) were positive for T. gondii, with 2 samples having titers of 1:25 and 4 having titers of 1:50. Four of 62 samples (6%) were positive for S. neurona, with 2 samples having titers of 1:25 and 2 having titers of 1:50.

    Prevalence of Troglodytella abrassarti Brumpt and Joyeux, 1912 in Wild Chimpanzees (Pan troglodytes schweinfurthii) at Mahale Mountains National Park in Western Tanzania
    Kaur, T.; Singh, J.; Lindsay, David S. (American Society of Parasitology, 2010-02)
    We examined stool samples for trophozoites of the entodiniomorphid ciliate Troglodytella abrassarti Brumpt and Joyeux, 1912, from a habituated group of chimpanzees (Pan troglodytes schweinfurthii) at NI abate Mountains National Park in western Tanzania. In our study, fresh fecal samples from identified individuals were collected immediately after defecation and fixed in 10% formalin. In total, 52 samples from 38 chimpanzees (61% of 62 chimpanzees in the group) were examined using a direct smear method. A stool sample from an individual collection date from an individual chimpanzee was examined up to 3 separate times before it was called negative. Forty-eight (92%) of the 52 samples were positive, and stools front 37 (97%) of the 38 chimpanzees were positive for trophozoites of T abrassarti. The high prevalence of T. abrassarti in these chimpanzees is consistent with previous reports of this organism in chimpanzees.
