Abstract

Hearts of 1,000 pigs killed at an abattoir in Iowa were bioassayed for the prevalence of tissue cysts of Toxoplasma gondii. One hundred grams of cardiac muscle from each pig was homogenized, digested in pepsin solution, and bioassayed in 10 mice. Five hundred grams of heart tissue from each of a subset of 183 pigs was also bioassayed in cats. Serum collected from the heart from each pig was assayed for anti-T. gondii antibodies in the modified agglutination test using formalin-fixed whole tachyzoites. Anti-T. gondii antibodies were found in 22.2% of pigs. Viable T. gondii was isolated from a total of 170 pigs; from 50 hearts by bioassay in mice, from 58 hearts by bioassay in both mice and cats, and from 62 pigs by bioassay in cats only. The success of isolation in cats (65.6%) was approximately twice that in mice (31.7%). Percentage of isolations of T. gondii with respect to reciprocal antibody titers (in parentheses) in pigs was: 3.7% (< 20), 37.1% (20), 38.1% (40), 60% (80), 75% (200), 77% (400), 83% (800), and 75.8% (> or = 2,000 to 16,000).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
