Polymerase Chain Reaction-Based Method for the Detection of Canine Heartworm (Filarioidea: Onchocercidae) in Mosquitoes (Diptera: Culicidae) and Vertebrate Hosts

Abstract

A polymerase chain reaction (PCR)-based test was developed to aid in identification of Dirofilaria sp. and for use in surveys for infected vectors of Dirofilaria immitis (Leidy). A set of PCR primers was designed based on the DNA sequence of a D. immitis surface antigen gene. The predicted product was a 378 base-pair DNA fragment. The target fragment was amplified from free D. immitis larvae (both L3 and microfilariae), individual infected mosquitoes, pools of 30 mosquitoes (including a single infected mosquito), infected mosquitoes stored desiccated at room temperature for 7 mo, and whole blood from a dog infected with D. immitis. These primers did not amplify a homologous fragment from a mermithid or from 4 other species of filarioid nematodes (including 1 other Dirofilaria species). Third-stage larvae from field-collected mosquitoes also were tested. Field-collected L3, identified tentatively as D. immitis, were confirmed by PCR. There was no amplification using the PCR test for L3 identified tentatively as Dirofilaria sp. (possibly D. tenuis Chandler). These data provide a strong indication of the specificity of these primers. The potential utility of this technique for detecting the presence of D. immitis in field populations of mosquitoes is discussed.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The prevalence of Dirofilaria spp. can be over-estimated if other filarial species are present and misidentified.

    “Thus, the prevalence of Dirofilaria spp. can be over-estimated if other filarial species are present and misidentified [13, 14]”

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.
