Improved experimental model of hepatic cystic hydatid disease resembling natural infection route with stable growing dynamics and immune reaction

Figure 2 Experiment design and follow-up plan. Three different concentrations were prepared for a parallel experiment design with long-term follow-up: group A (2000 protoscolices/100 μL), group B (200 protoscolices/100 μL), and group C (100 protoscolices/100 μL). After injection, the hydatid cyst formation, location, distribution, and size, pathology, and immunology were followed regularly till the 10^th month post injection.
