Repeated patent infection of adult dogs with Toxocara camis
Abstract
Three adult male greyhounds have been repeatedly infected with Toxocara canis by oral administration of 100 to 200 infective ova. Each infection has become patent as shown by the presence of eggs in faeces. Anthelmintic treatment between 7 and 14 weeks after infection yielded an average of 25% of the inoculum as adult worms. These dogs have continued to be fully susceptible to infection despite repeated exposure to this parasite, and despite the presence of scrum antibody to both parasite surface and secreted antigens. These findings imply that adult dogs may not always be immune to toxocaral infection and may therefore contribute significantly to the problem of environmental contamination with T. canis ova.

Adult dogs have the same susceptibility for patent infections as naïve patients when later re-exposed and even when repeatedly exposed to the parasite and having circulating antibodies vs ascarid surface antigens.
“Also, they have the same susceptibility for patent infections as naïve patients when later re-exposed and even when repeatedly exposed to the parasite and having circulating antibodies vs ascarid surface antigens [52,53].”

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.
