Summary
Schistosomiasis research has achieved much, including understanding immune responses and drug dosing. This work proposes a unified research agenda to overcome field divisiveness and advance schistosomiasis control.
Area of Science:
- Tropical Medicine
- Infectious Diseases
- Immunology
- Public Health
Background:
- Schistosomiasis research boasts a rich history of scientific and public health successes.
- Key achievements include understanding immunologic regulation in chronic infections and the role of Th2-type immune responses.
- The development of the "dose pole" for praziquantel administration represents a significant field accomplishment.
Purpose of the Study:
- To address diverse opinions and potential divisiveness within the schistosomiasis research community.
- To develop a comprehensive and cohesive research agenda for schistosomiasis.
- To foster collaboration and guide future research priorities in schistosomiasis control.
Main Methods:
- Literature review of historical schistosomiasis research accomplishments.
- Community engagement with diverse stakeholders in the schistosomiasis field.
- Consensus-building to formulate a unified research agenda.
Main Results:
- Identification of key areas of scientific and public health impact in schistosomiasis.
- Recognition of the need for a cohesive strategy to navigate diverse research interests.
- Proposal of a comprehensive research agenda to guide future schistosomiasis control efforts.
Conclusions:
- A unified research agenda is crucial for sustained progress in schistosomiasis control.
- Addressing the diversity of opinions and fostering collaboration will accelerate advancements.
- The proposed agenda aims to consolidate efforts and maximize impact in combating schistosomiasis.

Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
