Abstract

Five ferrets of each sex were each inoculated with 15 third‐stage infective larvae of Dirofilaria immitis to study radiographic and angiographic changes in the cardiopulmonary system following heartworm infection; 5 additional ferrets of each sex served as noninfected controls. Prior to inoculation and every 8 weeks thereafter until 40 weeks, the infected and noninfected ferrets were radiographed; angiographic examinations were done prior to necropsy. At necropsy, the worms in the heart, lungs, and associated vessels were counted, and lung histosections were prepared and examined for changes. Radiographic changes were seen in the right side of the heart and associated vessels of infected ferrets as compared with the noninfected ferrets, but changes were less prominent than those seen in heartworm‐infected dogs and cats. The changes were primarily an increase in the size of the right side of the heart, especially the right atrium. Radiographically, no changes could be visualized in the pulmonary vascular system. Worms in the enlarged cranial vena cava, azygous vein, and left caudal lobar pulmonary artery of infected animals were delineated by angiography. Histologically, no changes were seen in the pulmonary vascular tissues.

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.
