Adult worm recovery after Smp38 knockdown in vitro and subsequent injection of parasites into mice. Schistosomula were treated with unspecific, Smp38.1, and Smp38.2 dsRNAs for 4 days and then injected into mice. After 40 days, mice were perfused, adult worms were recovered and counted. Each symbol in the chart represents worm counts from each mouse. The horizontal lines represent the median values per treatment group. Published in Frontiers in Immunology. 2019. 10:21.
