Assessment of the parasitic burden in the smallholder pig value chain and implications for public health in Uganda por Roesel, Kristina

“…Trichinella-specific immunoglobulin G was found in 6.9% of the animals (95% CI: 5.6-8.6%) using a commercially available enzyme-linked immunosorbent assay (ELISA). Confirmatory testing by Western blot implied an overall seroprevalence of 2.1% (95% CI: 1.4-3.2%), and attempts to isolate muscle larvae using artificial digestion were unsuccessful. …”
