"Prevalence of Agglutinating Antibodies to Toxoplasma gondii and Sarcocystis neurona in Beavers (Castor canadensis) From Massachusetts," Journal of Parasitology, Vol. 91, No. 5, pp. 1228-1229. doi: http://dx.doi.org/10.1645/GE-543R.10022-3395http://hdl.handle.net/10919/49067The 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.application/pdfenIn Copyrightopossums didelphis-virginianaspecies sporocystsprocyon-lotorimmunoassaysurvivalraccoonsoocystskansasparasitologyArticle - Refereedhttp://www.bioone.org/doi/abs/10.1645/GE-543R.1https://doi.org/10.1645/ge-543r.1
