The Journal of Helminthology (JHL) was first published in 1923 and was originally created as a house journal of the London School of Hygiene and Tropical Medicine. The JHL was devised by its first Editor, Robert Leiper, to allow for rapid publication of results from the Department of Helminthology and its offshoot the Institute of Agricultural Parasitology. From this initial narrow focus the JHL has subsequently become not only internationally recognized but also retained its original emphasis on morphological, taxonomic and life cycle studies while embracing the emergence of new fields and technological advancements. The present review covers the historical development of the JHL over the last century from 1923 to 2023.

BACKGROUND: This study aims to compare parasitology technicians (ParaTechs) with medical staff parasitologists (MedParas) in terms of diagnostic ability and to assess the actual occurrence of gastrointestinal parasites in selected faecal samples from primary health care units (PHCUs). METHODS: The study included five PHCU ParaTechs in the El-Kassassin rural area, evaluated using a scoring system for their knowledge, skills, practices and parasitology laboratory facilities. Seventy-five faecal samples previously examined for ova and parasites by ParaTechs were chosen for re-evaluation by MedParas. RESULTS: The most deficient ParaTechs-related factor was the parasitological knowledge, which scored 23.9% of the maximum score, while ParaTechs had acceptable levels of skills and practices, scored 60% and 61%, respectively. Compared with MedParas, false positive ParaTech diagnoses made up 8.8% of all negative samples, while false negative diagnoses made up 85.4% of all positive samples. ParaTechs underestimated the count or misidentified the type of parasites in one-third of the true positive samples. The overall rate of misdiagnosis among ParaTechs was 53.3% of all samples. CONCLUSIONS: Regular ParaTech training, including culture and staining at parasitology labs, and collaboration between the Ministry of Health and Population and academic institutions are essential to increase ParaTechs diagnostic abilities.

The increase in the generation of Solid Urban Waste causes social, environmental problems and damages to the population's health. Professionals who work in the collection of recyclable waste are exposed to risks of contamination either by toxic elements or pathogenic organisms. The objective of the work was to estimate the types and prevalence of intestinal parasites inwaste pickers. A field research was carried out from December 2017 to April 2018 with the voluntary participation of 26 waste pickers belonging to three associations in the municipality of Conselheiro Lafaiete, Minas Gerais, Brazil (CAAE: nº 79937817.7.0000.8122). In addition to the application a socio-environmental questionnaire, each volunteer provided a stool sample for laboratory testing the parasitological examination. Of the 26 survey participants, four (15.4%) had a positive result and were infected by the parasites Giardia lamblia, Entamoebacoliand Iodamoeba butschlii. Among the main factors that can contribute to the infection these waste pickersare the ingestion of untreated water for consumption in addition to reduced access to Personal Protective Equipment(PPE) during waste management. One way to control the presence of parasites would be through health and environmental education actions, periodic parasitological examinations and permanent use of PPE.

The School of Veterinary Medicine, University College Dublin, Ireland, restructured the teaching of general pathology, parasitology, and microbiology in third year in 2018 as part of the development of an outcome-based curriculum. A new integrated teaching module was created, called Veterinary Pathobiology, which encompassed the three paraclinical subjects, worth 20 ECTS credits. Subject integration was driven and supported by case-based learning (CBL) activities, and practical classes, which were aimed at facilitating the understanding of basic disease processes, infectious agents, and the application of diagnostic tests. The disciplines maintained their identities within lectures which were aligned by content. The restructuring led to a reduction of contact hours by 20% and of assessment time by 40%. The examinations included integrated questions with an emphasis on the material students had covered in their CBL. Despite positive outcomes, which included equivalent examination scores and positive written feedback by students on teaching and learning, understanding, assessment, relevance, CBL, group work, and generic skills, the average scores for overall student satisfaction dropped dramatically in the second academic year of implementation. This followed the introduction of new regulations by the University relating to student progression, which was capped at "carrying" 10 ECTS credits, thus preventing students that failed the new module from progressing. Other criticisms of the new module by students included too little communication on the changes implemented in its first iteration and a workload perceived to be too heavy. Further restructuring is therefore necessary. This study highlights the process/pitfalls of integration/curricular innovation.

El cambio curricular es un proceso de transformaciones que expresa las modificaciones operadas en la sociedad en términos epidemiológicos, frente a la emergencia y reemergencia de parasitosis, en estrecha relación con la geografía médica y los condicionamientos sociales, económicos y políticos bajo los que se desarrolla la sociedad; por tanto, reconocer y tratar los principales parásitos que afectan al hombre y las enfermedades parasitarias asociadas a ellos resulta esencial para la formación médica de estos tiempos. La presente investigación tiene como objetivo comparar los resultados en las calificaciones en el examen de parasitología del 9no semestre de dos de las universidades públicas de la provincia del Guayas, Ecuador, en el periodo de noviembre de 2020. Se realizó un estudio exploratorio/descriptivo de la variable "Evaluación", que contuvo medidas de posición, dispersión y contraste de la normalidad, y el desempeño fue determinado mediante las listas de apreciación de competencias, establecido como instrumento de evaluación. De igual forma, se utilizó la técnica estadística de comparación de medias a través de la Prueba t para muestras independientes con un nivel de significancia del (5%). Los datos fueron procesados empleando el Programa Estadístico para Ciencias Sociales (SPSS v25). Concluyendo, que los estudiantes de la universidad de ESPOL tuvieron mejor puntuación en relación con la media, y menos dispersión en sus resultados con respecto a la UG. En líneas generales la mayoría de los estudiantes obtuvieron un alto desempeño de las competencias, siendo fundamental la constancia en la mejora del proceso de enseñanza de la parasitología(AU)

Curriculum change is a transformation process that expresses the changes that have taken place in society in epidemiological terms, in the face of the emergence and re-emergence of parasites, in close relation to the medical geography and the social, economic and political conditions under which society develops; therefore, recognizing and treating the main parasites that affect man and the parasitic diseases associated with them is essential for medical training in these times. The objective of this research is to compare the results in the qualifications in the parasitology exam of the 9th semester of two of the public universities of the province of Guayas, Ecuador, in the period of November 2020. An exploratory/descriptive study of the variable "Evaluation", which contained measures of position, dispersion and contrast of normality, and performance, was determined through the competency assessment lists, established as an evaluation instrument. Similarly, the statistical technique of comparison of means was used through the t-test for independent samples with a significance level of (5%). The data was processed using the Statistical Program for Social Sciences (SPSS v25). Concluding, that the students of the ESPOL University had a better score in relation to the average, and less dispersion in their results with respect to the UG. In general terms, most of the students obtained a high performance of the competences, being fundamental the constancy in the improvement of the parasitology teaching process(AU)

In comparative studies, the advantage of increased sample sizes might be outweighed by detrimental effects on sample homogeneity and comparability when small numbers of hosts from a different demographic of the same species are included in samples. A mixed sample of sunfishes (Lepomis spp.) was subdivided in different ways and examined using cumulative performance curves to determine whether the exclusion of larger hosts from a single-species sample and/or the inclusion of hosts of the same size demographic from closely related host species would produce more homogeneous samples. The exclusion of larger hosts from the single-species samples tended to reduce the aggregation of the infrapopulation samples, and mixed-species samples of smaller fishes tended to have lower degrees of aggregation for a given sample size relative to the single-species sample. Cumulative performance curves for diversity and richness, in concert with nonmetric multidimensional scaling of the infracommunities, demonstrated sunfish size to be a more reliable determinant of infracommunity similarity than sunfish species in this particular sample. The results demonstrate that cumulative aggregation curves can be an effective tool for delineating homogeneous and comparable subsamples and that, under some circumstances, it is possible to offset the smaller sample sizes that result from the exclusion of older/larger hosts by the addition of congeneric or confamilial hosts within the same size/age classes as the stratified sample.

O presente estudo objetivou analisar a produção científica brasileira sobre a doença de Chagas a partir de publicações indexadas na base de dados Web of Science. Foram coletados e analisados os dados de 1.008 publicações no período entre 2006 e 2020. A interpretação dos dados permitiu identificar um expressivo crescimento da produção científica brasileira sobre a doença de Chagas e a abrangência da temática em periódicos internacionais. Contudo, há um enfoque nas áreas biomédicas do conhecimento com destaque para a Parasitologia e um diminuto número de investigações direcionadas às áreas da Saúde Pública, Ciências Sociais e Farmacêuticas. A bibliometria desvelou as lacunas ainda existentes na produção nacional e a necessidade de fortalecimento de políticas direcionadas a editais de pesquisa no país.

The present study aimed to analyze the Brazilian scientific production on Chagas disease from publications indexed in the Web of Science database. Data from 1,008 articles published between 2006 and 2020 were collected and analyzed. The interpretation of the data allowed the identification of an expressive growth of Brazilian scientific production on Chagas disease and comprehensiveness of the theme in international journals. However, there is a focus on the biomedical areas of knowledge with emphasis on Parasitology and a small number of investigations directed to the areas of Public Health, Social Sciences and Pharmaceuticals. The bibliometry revealed the gaps that still exist in the national production and the need to strengthen policies directed to research edicts in the country.

Protozoan parasites are responsible for severe disease and suffering in humans worldwide. Apart from disease transmission via insect vectors and contaminated soil, food, or water, transmission may occur congenitally or by way of blood transfusion and organ transplantation. Several recent outbreaks associated with fresh produce and potable water emphasize the need for vigilance and monitoring of protozoan parasites that cause severe disease in humans globally. Apart from the tropical parasite Plasmodium spp., other protozoa causing debilitating and fatal diseases such as Trypanosoma spp. and Naegleria fowleri need to be studied in more detail. Climate change and socioeconomic issues such as migration continue to be major drivers for the spread of these neglected tropical diseases beyond endemic zones. Due to the complex life cycles of protozoa involving multiple hosts, vectors, and stringent growth conditions, studying these parasites has been challenging. While in vivo models may provide insights into host-parasite interaction, the ethical aspects of laboratory animal use and the challenge of ready availability of parasite life stages underline the need for in vitro models as valid alternatives for culturing and maintaining protozoan parasites. To our knowledge, this review is the first of its kind to highlight available in vitro models for protozoa causing highly infectious diseases. In recent years, several research efforts using new technologies such as 3D organoid and spheroid systems for protozoan parasites have been introduced that provide valuable tools to advance complex culturing models and offer new opportunities toward the advancement of parasite in vitro studies. In vitro models aid scientists and healthcare providers in gaining insights into parasite infection biology, ultimately enabling the use of novel strategies for preventing and treating these diseases.

In the five decades since the first publication of the International Journal for Parasitology, ecological parasitology has grown from modest beginnings to become a modern discipline with a strong theoretical foundation, a diverse toolkit, and a multidisciplinary approach. In this review, I highlight 12 advances in the field that have spurred its growth over the past 50 years. Where relevant, I identify pivotal contributions that have altered the course of research, as well as the influence of developments in other fields such as mainstream ecology and molecular biology. The 12 key advances discussed are in areas including parasite population dynamics and community assembly, the regulation of host population abundance and food web structure, parasites as agents of natural selection, the impacts of biodiversity and anthropogenic changes on host-parasite interactions, the biogeography of parasite diversity, and the evolutionary genetics of parasites. I conclude by identifying some challenges and opportunities lying ahead, which need to be met for the future growth of ecological research on host-parasite interactions.
