Research on the molecular genetics of Echinococcus has advanced significantly owing to its relevance in understanding genetic variation, host-parasite interactions, and the transmission of Echinococcus species. A bibliometric analysis was performed using RStudio (Bibliometrix) and VOSviewer to evaluate molecular genetic research on Echinococcus spp. published between 1985 and 2025. Data were extracted from Scopus, Web of Science, PubMed, Europe PMC, and ProQuest. The analysis revealed a steady rise in publications on Echinococcus molecular genetics, accelerating from the early 2000s and peaking around 2017, with a slight decline after 2023, reflecting fluctuations in research activity. Comparative analysis showed Echinococcus consistently surpassed Schistosoma, Taenia, and soil-transmitted helminths, peaking at 60 articles in 2020-2021. Early publications achieved high mean Total Citations (TC) per year, followed by a stable trend, indicating lasting impact. Leading journals included Parasitology Research (Germany; 70 articles, H-index 114), Veterinary Parasitology (Netherlands; 62, H-index 150), Parasitology (UK; 53, H-index 173), Acta Tropica (Netherlands; 34, H-index 122), and PLOS Neglected Tropical Diseases (USA; 28, H-index 172). Tehran University of Medical Sciences (54 articles) led institutions. Influential authors included D. P. McManus and T. Romig. Multinational studies (484 publications) had higher citations than single-country (474). Iran (121), China (116), and Italy (53) led global contributions, emphasising collaboration, genotyping, phylogeny, and veterinary applications. This bibliometric study underscores the evolving trends in Echinococcus molecular genetics, providing valuable insights for researchers and stakeholders to guide future investigations and collaborative strategies in controlling echinococcosis.

Canine dirofilariosis caused by Dirofilaria immitis and Dirofilaria repens is a vector-borne zoonotic infection of considerable veterinary and public health importance. Despite reports of the circulation of Dirofilaria spp. in neighboring countries, data on the molecular prevalence, species composition, and genetic diversity of these parasites in dogs from Kazakhstan remain limited. In the present study, owned, shelter, and stray dogs, which serve as the principal reservoirs of infection, were examined for the presence of microfilariae in blood, and the circulation of Dirofilaria spp. was molecularly confirmed. The study was conducted between September 2024 and January 2026 and included 751 canine blood samples collected from 10 regions of Kazakhstan. Initial screening was performed using the modified Knott test. Molecular identification was carried out through amplification of the mitochondrial cox1 gene, followed by DNA sequencing and comparative analysis with reference sequences available in GenBank. Phylogenetic analysis was performed to assess the genetic relationships of the detected isolates. The overall molecular prevalence of Dirofilaria spp. was 3.6% (27/751). The highest infection rate was recorded in the Aktobe region (22.3%), while positive cases were also detected in the Akmola (2.7%), Kostanay (1.7%), and West Kazakhstan (1.8%) regions. Species identification revealed the predominance of D. repens, whereas D. immitis was detected only in Aktobe region. Phylogenetic analysis confirmed the species identity of all obtained sequences and demonstrated a high degree of genetic similarity with Dirofilaria isolates previously reported from Europe and Asia. These findings confirm the circulation of Dirofilaria spp. among dogs in several regions of Kazakhstan and indicate the ongoing expansion of canine dirofilariosis in Central Asia. This study provides the first molecular genetic data on Dirofilaria spp. in dogs from Kazakhstan and highlights the need for continued epidemiological surveillance and assessment of potential risks to animal and human health.
