Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic
Open accessAbstract
SUMMARY: Dirofilariasis represents a zoonotic mosaic, which includes two main filarial species ( Dirofilaria immitis and D. repens ) that have adapted to canine, feline, and human hosts with distinct biological and clinical implications. At the same time, both D. immitis and D. repens are themselves hosts to symbiotic bacteria of the genus Wolbachia , the study of which has resulted in a profound shift in the understanding of filarial biology, the mechanisms of the pathologies that they produce in their hosts, and issues related to dirofilariasis treatment. Moreover, because dirofilariasis is a vector-borne transmitted disease, their distribution and infection rates have undergone significant modifications influenced by global climate change. Despite advances in our knowledge of D. immitis and D. repens and the pathologies that they inflict on different hosts, there are still many unknown aspects of dirofilariasis. This review is focused on human and animal dirofilariasis, including the basic morphology, biology, protein composition, and metabolism of Dirofilaria species; the climate and human behavioral factors that influence distribution dynamics; the disease pathology; the host-parasite relationship; the mechanisms involved in parasite survival; the immune response and pathogenesis; and the clinical management of human and animal infections.
Overview
AI snapshot
Written from the paper’s full text.
TL;DR
Dirofilariasis is a zoonotic mosaic caused mainly by *Dirofilaria immitis* and *D. repens*, with dogs as major reservoirs, cats and humans as less suitable hosts, and *Wolbachia* symbionts shaping pathology and treatment. The review synthesizes global epidemiology, clinical disease, diagnosis, treatment, and host-parasite immunology, emphasizing emergence/expansion and major knowledge gaps.
Key findings
- Approximately 1,782 human dirofilariasis cases have been reported: 372 pulmonary and 1,410 subcutaneous/ocular; *D. immitis* pulmonary cases predominate in the Americas, while *D. repens* subcutaneous/ocular cases predominate in the Old World.
- Canine *D. immitis* occurs worldwide in tropical and temperate regions, with prevalence examples including 1 to 12% in the United States, up to 48.8% on the Gulf Coast, 2.3 to 45% in Brazil, and 5 to 74% in Argentina; *D. repens* is exclusive to the Old World.
- Feline *D. immitis* infections tend to occur in the same areas as canine infections but at 5 to 20% of canine prevalence rates; cats often have low parasite burdens, transient or absent microfilaremia, and can develop heartworm-associated respiratory disease.
- *Wolbachia* are maternally transmitted filarial symbionts involved in molting and embryogenesis; *Wolbachia* surface protein (WSP) drives Th1 proinflammatory responses, and doxycycline is recommended by the American Heartworm Society for beneficial effects in heartworm management.
Methods
- Narrative review of human and animal dirofilariasis covering morphology, biology, protein composition, metabolism, climate and human behavioral factors, pathology, host-parasite relationships, immune response, and clinical management.
- Evidence synthesized from published literature, retrospective case reviews, seroepidemiological surveys, experimental and clinical studies, and global prevalence reports; no new primary data are presented.
- Main analysis is qualitative synthesis, with tables and figures summarizing proteins, human case data, vector species, and host-specific aspects of dirofilariasis.
Limitations
- The paper states that knowledge of the genome, proteome, biochemistry, metabolism, molting, pathogenesis, and survival mechanisms of *D. immitis* and *D. repens* remains limited, with human dirofilariasis having the greatest dearth of knowledge.
- The paper notes substantial underreporting and misdiagnosis, especially for pulmonary human cases, and states that retrospective reviews portray only “the tip of the iceberg”; epidemiological data are also limited in many regions, notably Africa.
- Evident from the text: as a narrative review without a described systematic search or quality appraisal, conclusions rely on heterogeneous studies and reported cases, so prevalence and case estimates may be biased by surveillance and reporting differences.

“Together with mass spectrometry, proteomics allowed the simultaneous identification of numerous proteins, comprising 39 proteins from D. immitis and 15 from D. repens, many of which were represented by several isoforms (157,158,313).”

The paper reports using two-dimensional electrophoresis and mass spectrometry to identify numerous D. immitis proteins; its Table 1 lists multiple spots for some proteins. But it reports 35 different proteins, not 39, and does not report identifying 15 D. repens proteins. The passage reporting the count is labeled Abstract in our copy; no page number is available.

The case report (www.ijmm.org; page unavailable) describes an eyelid infection caused by D. tenuis in India and says humans occasionally acquire animal filariae. It does not establish that subcutaneous or ocular infections from species other than D. repens are rare across the Old World, or compare their frequency with D. repens infections. (LLM, conf=0.75)
- Supportedcites [315] source
In the copy’s Dirofilaria discussion (indexed as Abstract; page unavailable), the authors report more than 400 human D. repens cases across Europe, Asia, and Africa, most involving subcutaneous or tissue around the eye. They place the human cases of other named subcutaneous or ocular Dirofilaria species chiefly in North America and say no human D. ursi-like infections had been reported in Japan or Russia. Together, these passages support the claim’s broad geographic comparison. (LLM, conf=0.84)

“In addition, some key features that are considered for worm species identification, including cuticular ridge size, ridge numbers, and ridge-to-ridge distance, are highly variable at different body areas of the same worm and even within a single transverse section, thereby rendering these criteria unreliable for diagnosis (315).”

Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.

§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > Dirofilaria spp. in Vector Species
“1.38% in Anopheles crucians and 0.85% in An. punctipennis in Georgia (235)”
§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > CONCLUSIONS AND FUTURE TRENDS
“| Aedes crucians | United States (235) | | Aedes notoscriptus | Australia (366) | | Aedes ochlerotatus | America (243) | | Aedes punctipennis | United States (235) |”

§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > Dirofilariasis in Human Hosts
“Fifty-two additional cases have been reported for various regions throughout Russia after that date (13,35,110,408), along with three more cases of pulmonary filariasis (132,197)”
§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > CONCLUSIONS AND FUTURE TRENDS

In the paper
§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > Energy Generation and Molting in Dirofilaria Species
“In microfilariae, nutrient acquisition is exclusively transcuticular, and only glucose, some amino acids, and RNA precursors are taken up (8,188).”
§ Human and Animal Dirofilariasis: the Emergence of a Zoonotic Mosaic > CONCLUSIONS AND FUTURE TRENDS
“There is a selective uptake of nutrients through both the digestive tract and the cuticle in microfilariae and adult worms.”

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.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
