Journal ArticleDOI
Multi-parallel qPCR provides increased sensitivity and diagnostic breadth for gastrointestinal parasites of humans: field-based inferences on the impact of mass deworming
Alice V. Easton,Alice V. Easton,Rita G. Oliveira,Elise M. O’Connell,Stella Kepha,Charles Mwandawiro,Sammy M. Njenga,Jimmy H. Kihara,Cassian Mwatele,Maurice R. Odiere,Simon Brooker,Joanne P. Webster,Roy M. Anderson,Thomas B. Nutman +13 more
TL;DR: KK may be an inadequate tool for stool-based surveillance in areas where hookworm or Strongyloides are common or where intensity of helminth infection is low after repeated rounds of chemotherapy.
Journal ArticleDOI
The role of water, sanitation and hygiene interventions in reducing soil-transmitted helminths: interpreting the evidence and identifying next steps
Susana Vaz Nery,Amy J. Pickering,Ebba Abate,Abraham Asmare,Laura Barrett,Jade Benjamin-Chung,Donald A. P. Bundy,Thomas Clasen,Thomas Clasen,Archie C. A. Clements,John M. Colford,Ayse Ercumen,Ayse Ercumen,Siobhan Crowley,Oliver Cumming,Matthew C. Freeman,Rashidul Haque,Birhan Mengistu,William E. Oswald,Rachel L. Pullan,Rita G. Oliveira,Katey Einterz Owen,Judd L. Walson,Ashrafedin Youya,Simon Brooker,Simon Brooker +25 more
TL;DR: A review critically summarises the available trial evidence and offers an interpretation of the observed heterogeneity in findings, which highlights three main issues which merit further consideration: intervention design, exposure assessment, and intervention fidelity assessment.
Journal ArticleDOI
Molecular evidence of hybridization between pig and human Ascaris indicates an interbred species complex infecting humans.
Alice V. Easton,Alice V. Easton,Shenghan Gao,Shenghan Gao,Scott P. Lawton,Sasisekhar Bennuru,Asis Khan,Eric Dahlstrom,Rita G. Oliveira,Stella Kepha,Stephen F. Porcella,Joanne P. Webster,Joanne P. Webster,Roy M. Anderson,Michael E. Grigg,Richard E. Davis,Jianbin Wang,Jianbin Wang,Thomas B. Nutman +18 more
TL;DR: A 296 megabase reference-quality genome comprised of 17,902 protein-coding genes derived from a single, representative Ascaris worm shows lumbricoides-like inheritance patterns supporting a highly interbred Ascar is species genetic complex.
Journal ArticleDOI
The Impact of Anthelmintic Treatment on Human Gut Microbiota Based on Cross-Sectional and Pre- and Postdeworming Comparisons in Western Kenya.
Alice V. Easton,Mariam Quinones,Ivan Vujkovic-Cvijin,Rita G. Oliveira,Stella Kepha,Maurice R. Odiere,Roy M. Anderson,Yasmine Belkaid,Thomas B. Nutman +8 more
TL;DR: The impact of roundworms and hookworms on gut microbial composition is quantified, suggesting that the impact is small, but that treatment of hookworm infection results in significant changes.
Journal ArticleDOI
Sources of variability in the measurement of Ascaris lumbricoides infection intensity by Kato-Katz and qPCR.
Alice V. Easton,Rita G. Oliveira,Martin Walker,Elise M. O’Connell,Sammy M. Njenga,Charles Mwandawiro,Joanne P. Webster,Thomas B. Nutman,Roy M. Anderson +8 more
TL;DR: Person-to-person differences explain the majority of variability in egg intensity measurements by qPCR and KK, with very little additional variability explained by the technical factors associated with the practical implementation of these techniques.
