Impacts of urbanisation level and distance from potential natural mosquito breeding habitats on the abundance of canine dirofilariosis
Open accessAbstract
Dirofilariosis is an emerging mosquito-borne veterinary and medical problem in the Northern hemisphere. The ecological investigation of 56 canine dirofilariosis cases in new endemic locations was performed in Szeged, Hungary. The aim was to analyse the influence of the spatial patterns of dog abundance and the potential mosquito breeding habitats on the spatial occurrence patterns of dirofilariosis in the city of Szeged. The limnoecological characterisation was based on the fluvial habitat classification of Amoros of natural water bodies; the built environment was evaluated using the UrbanisationScore urbanisation intensity measuring software. Dirofilaria immitis accounted for 51% and D. repens for 34.3% of the dirofilariosis cases, and in 20% of the cases only the Knott's test was positive. It was concluded that most of the cases were related to locations with a medium to high urbanisation index, although the proximity of mosquito-bearing waters also played an important role in the observed spatial infection patterns. We found that the distance from potential mosquito habitats and the urbanisation intensity determine the abundance of dirofilariosis in urban environments.

Széll et al. detected canine heartworm prevalence from 0.5 to 8% in Hungary between 2007 and 2018, with most positive dogs in central, western, and southern regions.
“Széll et al. [115] detected prevalence from 0.5 to 8% between 2007 and 2018, being most of the positive dogs located in the central, western, and southern regions of the country.”

In Hungary, increases in temperatures between 1-2 °C have presumably contributed to spread of D. immitis from the south to the north of the country.
“Hungary is an example of this, where increases in temperatures between 1–2 °C were reported and has presumably contributed to spread the presence of D. immitis from the south to the north of the country [115].”

In Hungary, a study between 1995 and 2018 reported a rapid spread of D. immitis based on geo-referencing of infected dogs and golden jackals and detection of anomalous annual temperature data compared to the four previous years.
“In Hungary, a study carried out between 1995 and 2018 reported a rapid spread of the disease, based on the geo-referencing of infected animals (dogs and golden jackals) and the detection of anomalous annual temperature data compared to the four previous years.”
From What has happened to heartworm disease in Europe in the last 10 years? (2022) · cites this paper as [115]
The authors of the Hungarian study concluded that two main factors favoured the spread of D. immitis: increase in temperatures and increase and expansion in the population of golden jackals, the most important reservoir of heartworm in the fauna of the Mediterranean Balkans.
“The authors concluded that two main factors were favouring this spread: the increase in temperatures as well as the increase and expansion in the population of golden jackals, the most important reservoir of heartworm in the fauna of the Mediterranean Balkans.”

A high density of suitable definitive hosts should be related with higher abundance of dirofilariosis.

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.
