Abstract

The present study reports the applicability of a multiplex PCR for the simultaneous detection and differentiation of common filarioids infecting dogs, i.e., Dirofilaria immitis, Dirofilaria repens, Acanthocheilonema reconditum and Cercopithifilaria sp. Amplicons of different sizes (i.e., 170 bp, 480 bp, 590 bp and 300 bp, respectively) of regions within the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene were amplified on a single-step multiplex PCR using a mix of species-specific forward primers coupled with a single reverse primer. Experiments were carried out by amplifying genomic DNA extracted from blood or skin samples test-positive for microfilariae (mff). The number of mff present in each blood sample was quantified (from 800 to 25,000 mff/ml for A. reconditum and D. repens, respectively) and mixed blood samples were tested for the simultaneous detection of DNA from these mff. Specific amplicons for blood-circulating mff of A. reconditum, D. immitis and D. repens and for those whose adults are localized in skin (i.e., A. reconditum and Cercopithifilaria sp.) were simultaneously detected on agarose gel up to a dilution of 250 mff/ml for D. repens. The specific identity of the amplicons was confirmed by sequencing. The multiplex PCR assay reported herein represents a new tool for the molecular detection and differentiation of canine filarioids in blood and skin samples.

  • A multiplex PCR based on amplification of a mitochondrial gene of blood-circulating microfilariae of D. immitis, A. reconditum and D. repens and of Cercopithifilaria spp. is useful for their molecular detection and differentiation in blood and skin samples.

    “A multiplex PCR based on the amplification of a mitochondrial gene of blood-circulating microfilariae of D. immitis, A. reconditum and D. repens and of Cercopithifilaria spp. has also been shown to be useful for their molecular detection and differentiation in blood and skin samples [131].”

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.
