Background: The more than 4100 species of phytoparasitic nematodes are responsible for an estimated economic loss in the agricultural sector of nearly $125 billion annually. Knowing the main lines of research and concerns about nematodes that affect plants is fundamental. Methods: For this reason, an analysis using bibliometric data has been carried out, with the aim of tracing the state of world research in this field, as well as knowing the main lines of work, their priorities, and their evolution. Results: This will allow us to establish strategic lines for the future development of this research. Conclusions: The analysis has allowed us to detect that the interest in nematodes affecting plants has not stopped growing in the last decades, and that tomato, soybean, and potato crops are the ones that generate the most interest, as well as nematodes of the genus Meloidogyne and Globodera. Likewise, we have detected that the main lines of research in this field are focused on biological control and host–parasite interaction.

Background: Malaria is one of the infectious diseases of greatest interest to the scientific community and of greatest concern to international health authorities. Traditionally, the focus has been on Plasmodium falciparum, the parasite that causes the most severe form of the disease in Africa. However, in the last twenty years, the Plasmodium vivax parasite, responsible for a large number of cases in Latin America, the Middle East, South and Southeast Asia, the Horn of Africa, and Oceania, has also generated enormous interest due, among other things, to the published evidence that it can cause severe malaria. Methods: In this paper, the international scientific publication on malaria and P. vivax has been analyzed using the Scopus database to try to define global trends in this field of study. Results: It has been shown that events such as the emergence of resistance to certain drugs can break a trend. The important role of non-malaria-endemic countries such as the USA or Switzerland in malaria research is also evident. Conclusions: International cooperation will be essential for the eradication of the disease. Moreover, in this sense, the general vision given by the bibliometric analysis of malaria caused by P. vivax is fundamental to paint the picture regarding the current situation and encourage international cooperation and control efforts.

This study analyzed fifty years of severe malaria research worldwide. Malaria is a parasitic disease that continues to have a significant impact on global health, particularly in sub-Saharan Africa. Severe malaria, a severe and often fatal form of the disease, is a major public health concern. The study used different bibliometric indicators such as the number of publications, citations, authorship, and keywords to analyze the research trends, patterns, and progress made in the field of severe malaria. The study covers the period from 1974 to 2021 and includes articles from Scopus. The results of the study indicated that there has been a steady increase in the number of publications on severe malaria over the past fifty years, with a particular increase in the last decade. The study also showed that most of the publications are from USA and Europe, while the disease occurs in Africa, South-East Asia, and the Americas. The study also identified the most frequent keywords used in the publications, and the most influential journals and authors in the field. In conclusion, this bibliometric study provides a comprehensive overview of the research trends and patterns in the field of severe malaria over the past fifty years and highlights the areas that need more attention and research efforts.

Blastocystis spp. is the most prevalent human enteric protist, yet its clinical significance remains controversial. Currently recognized as a genetically diverse stramenopile with zoonotic potential, it comprises at least 42 subtypes, of which ST1–ST4 account for most human infections. Despite more than a century of research, its pathogenic role and ecological interactions are still debated. We performed a comprehensive bibliometric analysis of global scientific production on Blastocystis spp. from 1917 to 2025 using the Scopus database, retrieving 3710 publications. Temporal trends, geographic distribution, leading authors and institutions, and thematic evolution were assessed through keyword normalization and classification into five categories: classical diagnosis, PCR/molecular approaches, genetics/phylogeny, clinical/epidemiology, and microbiota. Results indicate a steady increase and a subsequent acceleration in publication trends since the late 1980s, with a compound annual growth rate of 11.56% between 1988 and 2025. Early research was dominated by microscopy-based diagnosis, whereas the introduction of PCR and sequencing technologies reshaped the field by enabling subtype identification and phylogenetic analysis. Since 2010, clinical and epidemiological studies have expanded significantly, and microbiota-oriented research has emerged as a growing line of investigation. Co-occurrence analysis indicates that Blastocystis spp. is frequently studied in the context of polyparasitism and intestinal coinfections. Overall, Blastocystis spp. research has evolved from descriptive parasitology to a multidisciplinary field integrating molecular, clinical and ecological approaches, highlighting the need for context-dependent models of host–parasite–microbiota interactions.
