| Abstract: | Fifteen thousand three hundred and eighteen porcine sera from all regions of Canada were examined for the presence of anti-Trichinella antibodies using the enzyme-linked immunosorbent assay with an excretory-secretory antigen. Four sera (0.026%) revealed the presence of anti-Trichinella antibodies, with titers (optical density readings) that fell in the low positive or high negative range on repeated examinations. One animal originated in British Columbia and three in Ontario. Serological examination of swine in the herds at time of traceback did not reveal further animals with anti-Trichinella antibodies. |
