Abstract
[Display omitted]
► Heat treatment of Taenia hydatigena eggs for 5min. ► In vitro and in vivo analysis of viabilities. ► In vitro reduction in viability of 99.47% at 60.00°C. ► In vivo reduction in viability of 100.00% at 57.38°C.
Effects of heat treatments on activation and infectivity of Taenia hydatigena eggs were assessed. Eggs containing oncospheres were used for in vitro and in vivo studies to determine the response to 5min of heat treatment, ranging from room temperature (22°C) to 60°C. The study demonstrated 99.47% and 100% reduction in oncosphere activation or infectivity after 5min of heat treatment at 60°C and 57.38°C under in vitro and in vivo conditions, respectively. Similar results between the two approaches indicted the appropriateness of the in vitro methods to identify oncosphericidal treatments of practical significance. Similar heat treatments may also be effective against Taenia saginata and help to reduce occurrence of beef cysticercosis.
