Abstract

This survey was conducted to investigate the presence of Dirofilaria immitis and Dirofilaria repens in native dogs and cats living in an area of Italy where animal and human dirofilarioses have been sporadically reported in the past few years. From May 2008 to March 2009 individual blood samples were collected from 300 native cats and 300 native dogs in the Abruzzo region of central Italy. All 600 samples were subjected to a Knott modified method, to a test for the detection of circulating D. immitis antigen and to two species-specific PCR-coupled sequencing protocols. Epidemiological data were collected and then correlated with the filarial prevalence by univariate and multivariate statistical analyses. Twenty-five dogs (8.3%) and six cats (2%) were positive for filariae in at least one diagnostic test, with an overall prevalence rate for D. immitis and D. repens of 2.3% and 5.6% in dogs and 0.3% and 1.6% in cats, respectively. Male and large sized dogs resulted more likely to be infected by Dirofilaria spp., possibly due to the fact that animals living outdoor and of large size are more exposed to mosquito bites. However these factors were not confirmed as convincing risk factors by multivariate analysis. The results are discussed, together with the origin of these new autochthonous foci in central Italy and the present expansion southward of canine and feline filariae in Italy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In Italy, D. immitis is endemic in northern Italy and has now spread all over the country, showing a current change of distribution throughout the Italian territory, while canine and feline heartworm infection is more frequently diagnosed in southern regions of Italy.

    “In Italy, D. immitis is endemic in northern Italy and has now spread all over the country, which shows a current change of distribution of this parasite throughout the Italian territory while canine and feline heartworm infection is more frequently diagnosed in southern regions of Italy (Otranto et al., 2009; Traversa et al., 2010a).”
  • In Italy, in a recent study carried out in 2008 and 2009, in the Abruzzo region of central Italy prevalences of 2.3 and 0.3% were found in native dogs and cats, respectively.

    “In a recent study carried out in 2008 and 2009, in the Abruzzo region of central Italy prevalences of 2.3 and 0.3% were found in native dogs and cats, respectively (Traversa et al., 2010a).”
  • Moxidectin showed a high degree of efficacy in treating Dirofilaria repens infection, including potential ability to kill adults, after a single administration.

    “The latter molecule also showed a high degree of efficacy in treating D. repens infection, including potential ability to kill adults, after a single administration [112-114].”

  • Commercial kits for detection of antigens released in the blood by adult female D. immitis are an alternative method for diagnosing D. immitis infestation in dogs.

    “An alternative method for diagnosing D. immitis infestation in dogs is the use of commercial kits for the detection of antigens released in the blood by adult females.”

  • A study in central Italy found a prevalence of D repens infection of 1.6% in cats compared with 5.6% in dogs.

    “a study performed in central Italy using both modified Knott and PCR tests found a prevalence of 1.6% in cats compared with 5.6% in dogs.”

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.
