We also describe further applications using the device for molecular analysis and viral genotyping.

  A Loop-mediated Isothermal Amplification (LAMP) Assay for Rapid Identification of Bemisia tabaci Simon Blaser^1,2,3, Hanspeter Diem⁴, Andreas von Felten⁴, Morgan Gueuning¹, Michael Andreou⁵, Neil Boonham^6,7, Jennifer Tomlinson⁶, Pie Müller^2,3, Jürg Utzinger^2,3, Beatrice Frey¹, Jürg E.

The protocol requires minimal laboratory training and can, therefore, be implemented on-site at points of entry for plant imports such as seaports and airports.

  Determining Soil-transmitted Helminth Infection Status and Physical Fitness of School-aged Children Peiling Yap^1,2, Thomas Fürst^1,2, Ivan Müller^1,2, Susi Kriemler^1,2, Jürg Utzinger^1,2, Peter Steinmann^{1,2 1}Department of Epidemiology and Public Health, Swiss Tropical and Public Health Institute, Basel, Switzerland, ²University of Basel, Basel, Switzerland Chronic infection with soil-transmitted helminths (STHs) causes malabsorption, stunting, and wasting in the growing child. Hence, it is plausible that these infections also reduce the physical fitness of children. Here, we visualize two techniques for the diagnosis of STHs and the 20-meter shuttle run test for assessing children's physical fitness.
