Dioctophyme renale, also known as the giant red kidney worm, is a parasitic nematode that infects various mammalian hosts, including dogs, and is associated with an important renal pathology. This case report describes the first known D. renale parasitism in a 5-month-old puppy from Uruguay. The animal presented with hematuria and was diagnosed through abdominal ultrasonography, which revealed characteristic ring-like structures in the right kidney, and urine sedimentation, which confirmed the presence of D. renale eggs. The dog underwent nephrectomy to remove the adult female parasite. While D. renale is typically associated with a prepatent period of 3.5 to 6 months in canines, this case is notable for the early presence of a mature parasite in a young dog. This finding suggests the possibility of a shorter prepatent period or alternative transmission routes, such as transplacental or lactogenic transmission. The case highlights the importance of including dioctophymosis in the differential diagnosis of young puppies in endemic areas, especially near freshwater sources. Given the zoonotic potential of D. renale, this case emphasizes the need for surveillance of this parasite, particularly in regions where untreated water and fish consumption pose risks to both animals and humans.

Currently, more than 500,000 cases of various helminthes in humans are reported annually in the Russian Federation. This figure may not reflect the true incidence of helminthes, as only nine separate nosological forms are compulsory notifiable. The rest of the species of detected helminthes are included in a separate category of “other helminthes” or “rare helminthes”. The bulk of the latter is represented by the helminthes with a rate of incidence that does not exceed one case per 100,000 people. This review is based on data derived from publications in the Russian language, both from the Russian Federation and international, as well as data available from various health treatment facilities in Russia. These data largely cover the period of the 1990s–2010s. A total of 15 species of “rare helminthes” are described in this review: anisakiosis, capillariosis, clonorchosis, dioctophymosis, dipylidiosis, echinochasmosis, fasciolosis, gastrodiscoidosis (amphistomiosis), metagonimosis, metorchiosis, nanophyetosis, pseudamphistomosis, sparganosis (spirometrosis), strongyloidosis and trichostrongylosis. Details of their geographical distribution, clinical and epidemiological peculiarities, and the difficulties they pose in diagnosis are provided. The public health importance of “rare helminthes” in Russia at present and in the forthcoming years is stressed. Full article
