The Intestinal Roundworm Releases Antimicrobial Factors Which Interfere With Bacterial Growth and Biofilm Formation.

Front Cell Infect Microbiol 2018 7;8:271. Epub 2018 Aug 7.

Department of Veterinary Medicine, Institute of Immunology, Freie Universität Berlin, Berlin, Germany.

Ascariasis is a widespread soil-transmitted helminth infection caused by the intestinal roundworm in humans, and the closely related in pigs. Progress has been made in understanding interactions between helminths and host immune cells, but less is known concerning the interactions of parasitic nematodes and the host microbiota. As the host microbiota represents the direct environment for intestinal helminths and thus a considerable challenge, we studied nematode products, including excretory-secretory products (ESP) and body fluid (BF), of to determine their antimicrobial activities.

Infections of Soil-Transmitted Helminth in Refugees from North Korea.

Korean J Parasitol 2018 Jun 30;56(3):291-294. Epub 2018 Jun 30.

Division of Gastroenterology, Department of Internal Medicine, College of Medicine, Dankook University, Cheonan 31116, Korea.

Soil-transmitted helminthiases (STH) are now no longer public health problems in the Republic of Korea (South Korea), but their status are unavailable in the residents of North Korea (NK) despite the expectation of large scale traffic and future reunification of the Korean Peninsula. A total of 20 female refugees from NK who had been admitted to the Division of Gastroenterology, Dankook University Hospital, were subjected in this study. Among them, 15 refugees were examined by the colonoscopy and 10 ones were examined with the stool examination (formalin-ether sedimentation). Read More

Department of Medicine, Henry J. Carter Specialty Hospital and Nursing Facility, New York, New York, USA.

Intestinal parasitic infections are a major public health issue across the world and particularly in rural and urban areas of tropical and subtropical countries. Those at increased risk include inhabitants of poor and disadvantaged regions, which are more likely to have inadequate environmental sanitation, insufficient water supply, greater contact rates with reservoirs of infection, limited health literacy, and socioeconomic disparities. Of the intestinal nematodes (roundworms) that parasitize the human gastrointestinal tract, is the largest in terms of size. Read More

Department of Pathology, Baylor College of Medicine, Houston, TX 77030.

Epigenetic mechanisms, such as DNA methylation, determine immune cell phenotype. To understand the epigenetic alterations induced by helminth coinfections, we evaluated the longitudinal effect of ascariasis and schistosomiasis infection on CD4 T cell DNA methylation and the downstream tuberculosis (TB)-specific and bacillus Calmette-Guérin-induced immune phenotype. All experiments were performed on human primary immune cells from a longitudinal cohort of recently TB-exposed children. Read More

UMMISCO, IRD / Sorbonne Université, Bondy, France.

Multi-species interactions can often have non-intuitive consequences. However, the study of parasite interactions has rarely gone beyond the effects of pairwise combinations of species, and the outcomes of multi-parasite interactions are poorly understood. We investigated the effects of co-infection by four gastrointestinal helminth species on the development of cerebral malaria among Plasmodium falciparum-infected patients. Read More

Parasite allergens.

Mol Immunol 2018 Aug 24;100:113-119. Epub 2018 Mar 24.

Institute for Immunological Research, University of Cartagena, Cartagena, Colombia.

Human IgE against helminths is a normal component of the whole protective response elicitesd during infection, when specific IgE to a great number of antigens is produced; however, few of those IgE binding components are actually allergens. In general, considering the strong Th2/IgE responses during helminth infections is intriguing that they are not usually associated with allergic symptoms, which probably (but not exclusively) depends on parasite-induced immunomodulation. However, allergic manifestations have been described during some helminth infections such as ascariasis, strongyloidiasis, anisakiasis and hydatidosis. Read More

Turning poop into profit: Cost-effectiveness and soil transmitted helminth infection risk associated with human excreta reuse in Vietnam.

PLoS Negl Trop Dis 2017 Nov 27;11(11):e0006088. Epub 2017 Nov 27.

Center for Public Health and Ecosystem Research, Hanoi University of Public Health, North Tu Liem, Hanoi, Vietnam.

Human excreta is a low cost source of nutrients vital to plant growth, but also a source of pathogens transmissible to people and animals. We investigated the cost-savings and infection risk of soil transmitted helminths (STHs) in four scenarios where farmers used either inorganic fertilizer or fresh/composted human excreta supplemented by inorganic fertilizer to meet the nutrient requirements of rice paddies in the Red River Delta, Vietnam. Our study included two main components: 1) a risk estimate of STH infection for farmers who handle fresh excreta, determined by systematic review and meta-analysis; and 2) a cost estimate of fertilizing rice paddies, determined by nutrient assessment of excreta, a retailer survey of inorganic fertilizer costs, and a literature review to identify region-specific inputs.

Prev Vet Med 2017 Dec 22;148:10-20. Epub 2017 Sep 22.

Instituto de Ciências Biomédicas Abel Salazar, Universidade do Porto. Rua de Jorge Viterbo Ferreira, 228, 4050-313, Porto, Portugal; EPIUnit - Instituto de Saúde Pública, Universidade do Porto, Rua das Taipas, 135, 4050-600, Porto, Portugal.

Ascariasis is considered a common parasitosis of swine worldwide. The disease causes significant economic losses due to its effect on feed conversion ratio and liver condemnations at slaughter (liver milk spots). This study aimed to characterise the between-farm and spatial variance in porcine ascariasis in England and to assess the association between the percentage of infected animals and potential environmental risk factors, including production system, socioeconomic deprivation, soil characteristics (pH, topsoil bulk density, topsoil organic matter, topsoil texture class, soil water regime, topsoil available water capacity, and elevation), and climatic conditions (relative humidity, air temperature, and rainfall) before slaughter.

Department of Parasitology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Worm infections continue to be among the most common diseases affecting children from low and middle income countries. Major worm infections of public health importance include Ascariasis, Trichuriasis, Hookworm, and Enterobiasis, which are transmitted through contaminated soil. In India, combined prevalence rates of worm infestation as per pooled data of 127 surveys is over 20%. Read More

Status of soil-transmitted helminth infections in schoolchildren in Laguna Province, the Philippines: Determined by parasitological and molecular diagnostic techniques.

PLoS Negl Trop Dis 2017 Nov 6;11(11):e0006022. Epub 2017 Nov 6.

Research School of Population Health, The Australian National University, Canberra, Australia.

Background: Soil-transmitted helminths (STH) are the most common parasitic infections in impoverished communities, particularly among children. Current STH control is through school-based mass drug administration (MDA), which in the Philippines is done twice annually. As expected, MDA has decreased the intensity and prevalence of STH over time. Read More
