Summary: This study optimized the sample processing methodology and standardized pyrosequencing in soil-transmitted helminth (STH) pooled eggs. The protocols developed in this study can be used for large-scale screenings or anthelmintic efficacy trials in STH populations. The results suggest that the new pyrosequencing assays designed in this study provided accurate SNP frequencies in simulated resistance levels.

Summary: This study assessed the prevalence and intensity of soil-transmitted helminths (STH) infection among individuals in model and non-model households in Jimma zone. The study found that the prevalence and intensity of STH infection were higher in non-model households than in model households. Factors such as household training status, age of participants, and latrine use pattern were found to be significant predictors of STH infection prevalence.

Summary: This study presents a general framework to understand the impact of adherence and non-adherence behavior on mass drug administration (MDA) programs for neglected tropical diseases (NTDs). By developing probability models informed by observed adherence behavior, the study explores how different patterns influence the success of MDA programs. The analysis conducted on the TUMIKIA data highlights the importance of accurately capturing non-adherence patterns for effective control measures.

Summary: Soil-transmitted helminths are highly prevalent in the Asia-Pacific region, with a 96.5% prevalence in dogs in Kiribati. Urgent implementation of treatment and prevention programs is advocated to address these zoonotic pathogens, in accordance with the Kiribati-World Health Organization Cooperation Strategy 2018-2022.

Summary: Human mobility is a contributing factor to the spread of infectious diseases, and understanding this can aid in planning interventions. This study focuses on the spatial dynamics of hookworm, a common parasitic infection, and develops a transmission model based on data from Kenya. The model considers human mobility and successfully reproduces observed patterns of infection decline during a mass chemotherapy trial. The results highlight the importance of considering mobility in the design of elimination programs for helminth transmission.

Summary: Despite major efforts to control soil-transmitted helminth infections in the Philippines for nearly two decades, high prevalence rates persist due to suboptimal mass drug administration coverage, limited water, sanitation, and hygiene programs, and inadequate health education. Sustainable delivery of integrated control approaches is crucial for reducing the burden of soil-transmitted helminth infections in the Philippines.

Summary: After 10 years of high coverage integrated mass drug administration, Togo has achieved a low prevalence of schistosomiasis infection through sub-district implementation. However, soil-transmitted helminth (STH) infection remains a problem in some areas. additional measures such as improving treatment coverage among preschool age children and hygiene and sanitation practices are needed.

Summary: Gastrointestinal nematodes have a negative impact on childhood growth, cognition, nutrition, education, productivity, income, and pregnancy. The development of an anthelmintic for mass drug administration must be safe, effective, inexpensive, stable without a cold chain, and massively scalable. The Bacillus thuringiensis Cry5B (IBaCC) has been proven to be a safe, inexpensive, highly effective, easy-to-manufacture, and scalable anthelmintic for treating human GINs.

Summary: Drug repurposing from veterinary to human medicine has been the main strategy to develop anthelminthics for the treatment of helminthiasis. A systematic comparison of the anthelminthic activity profile of derivatives of these drugs has not been conducted yet. The study reveals pronounced differences in activity against larval and adult stages among different classes of anthelminthics, highlighting the importance of evaluating drugs against different species and stages for potential candidates.

Summary: This study aimed to explore the socioeconomic and environmental factors related to soil-transmitted helminth (STH) infection in indigenous villages in Argentina. The study found that specific environmental factors, such as vegetation pattern and impervious surface density, played a major role in the transmission and distribution of STH. Furthermore, socioeconomic factors, such as walking barefoot and overcrowding, were significantly correlated with infection intensity.

Summary: This study identified resistance to fenbendazole in the common intestinal helminth of turkeys, Ascaridia dissimilis. In turkeys, infection with resistant isolates significantly impacted feed conversion and weight gain. The presence of fenbendazole-resistant worms could have significant economic implications for turkey production.

Summary: Haemonchus contortus is a parasitic nematode that infects small ruminants and causes health issues and economic losses in the livestock industry. The treatment for this parasite primarily relies on broad-spectrum anthelmintics, but resistance has emerged. Levamisole (LEV) is an important treatment option, as resistance to LEV is less common. Genetic variation at the acr-8 locus has been implicated in LEV resistance.

Summary: Long-term intensive use of anthelmintics has led to widespread anthelmintic resistance, but it can also select for other biological traits. This study highlights examples of changing parasite dynamics that don't fit the definition of anthelmintic resistance, and explores cases where anthelmintic resistance has occurred along with coselection for other traits. Suggestions are made for collecting more information and addressing these knowledge gaps.
