Canine filariasis in Salamanca (northwest Spain)
Open accessAbstract
A survey of dogs in four areas of Salamanca province (northwest Spain) was carried out to determine the prevalence of filariids in the canine population. Blood samples from 293 dogs were tested for the presence of microfilariae, using a modification of the Knott technique. For correct identification of filariid species, blood smears associated with the 43 positive Knott tests were histochemically stained for demonstration of the somatic distribution of acid phosphatase activity. The survey revealed the presence in the northwest of Spain of Dirofilaria immitis, D. repens and Dipetalonema reconditum, with an overall prevalence in Salamanca of 12.3%, 0.3% and 2.1% respectively. The greater prevalence of canine heartworm was found in the irrigated area, where 33.3% of the dogs harboured microfilariae. The relationship between the prevalence of D. immitis and mosquito populations, and the influence of host sex and age in this infection, are analysed.

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.
