Endoparasite prevalence and recurrence across different age groups of dogs and cats
Open accessAbstract
The apparent prevalence of endoparasite infections across different age groups was calculated from 6555 dogs and 1566 cats that had a fecal examination performed upon presentation to the Veterinary Hospital of the University of Pennsylvania between 1997 and 2007. Based on notations from the medical history indicating prior parasite infections, estimates of recurrence were generated for each common group of parasites, including Trichuris, Giardia, ascarids, hookworms, Cystoisospora, and tapeworms. Endoparasitism was predominantly a disease of younger animals, with peak prevalence observed almost uniformly in dogs under 6 months old, with the exception of Trichuris with its longer pre-patent period, and in cats less than 18 months old. Furthermore, nearly 50% of dogs under 6 months old with a history of parasites, were diagnosed with at least one species of parasite on subsequent fecal examination. The percentage dropped to 18.4% in animals aged 1-4 years, but again increased to 31.5% in animals over 10 years old. There was no reported recurrence of Giardia or Cystoisospora from canine or feline patients older than 1 year. The recurrence of whipworm rose steadily with age, while hookworm and roundworm recurrence peaked in patients 1-4 years old. Findings from the study emphasize the importance of follow up fecal examinations and treatments in patients diagnosed with endoparasites.

“…with parasite recurrence is that the immune system of very young dogs is unable to generate long term immunity to the parasites during development, while the immune system of older animals may begin to lose anamnestic responses against previously seen parasites (Day, 2007; Muirhead et al., 2008).”

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.
