Abstract

Dirofilaria immitis is the agent of the heartworm disease in canids and felids, and of pulmonary dirofilariosis in man. Like other filariae, D. immitis harbours endosymbion Wolbachia bacteriae. In this work we analyse the response of specific IgE antibodies against both D. immitis antigens and the Wolbachia surface protein (WSP) in two groups of persons living in an area of canine endemia, one presenting high levels of total IgE (group 1) and other with normal levels (group 2). Infections with D. immitis were demonstrated by the presence of specific IgG in 228 individuals(48.8%) of the group 1 and only in one of the group 2. Specific IgE antibody response against D. immitis antigens was detected only in individuals of the group 1. IgE response against WSP was not detected in any group. The IgE response was directed mainly against two molecules of 33 and 42 kDa of the antigenic extract of D. immitis. These molecules were identified by mass spectrometry as a galectin and an aldolase, respectively. Their possible role in the survival mechanisms of the parasite and their contribution to development of allergic reactions in individuals resident in areas with heartworm disease are discussed.

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.
