| efficacy of ivermectin in hookworms as examined in ancylostoma caninum infections. | single oral doses of ivermectin were given to dogs with moderate or heavy infections of ancylostoma caninum (egg counts ranging from 7,100 to 41,700 eggs/g feces) at 100, 50, 30, or 10 micrograms/kg body weight. each of these dosages was effective in clearing the infection completely, so that numerous worms were passed in the feces on days 1-3, but no worm was recovered from the intestinal tract at necropsy on day 4 after treatment. in contrast, an average of 178 worms per dog was recovered at n ... | 1989 | 2723924 |
| a preliminary study on the use of enzyme-linked immunosorbent assay (elisa) for detection of trichinella spiralis infections in dogs. | an enzyme-linked immunosorbent assay (elisa) was developed to detect trichinella spiralis infections in dogs using rabbit anti-canine igg-horseradish peroxidase prepared according to the improved periodate method and an antigen purified from t. spiralis larvae by sephadex g-200 chromatography. sixty-six canine sera were tested for trichinosis by the elisa and it showed a detection rate which was significantly higher than that by trichinoscopy. this antigen of t. spiralis appeared not to cross-re ... | 1989 | 2741302 |
