Viability of Echinococcus granulosus protoscolices at different conditions

Viability of Echinococcus granulosus protoscolices at different conditions

Veterinary Parasitology 150(1-2): 84-87

The aim of this study was to examine the longest survival time of Echinococcus granulosus protoscolices stored at different humidities and constant temperatures from -10 to +40 degrees C. Sheep livers containing hydatid cysts obtained from slaughterhouses were taken to the laboratory within 3h and transferred into incubation cabinet previously set at -10, 0, +10, +20, +30 and +40 degrees C with different relative humidity (RH). Viability of protoscolices was assessed by 0.1% eosin staining. The longest survival times were 3 days at -10 degrees C (50% RH), 36 days at 0 degrees C (60% RH), 28 days at 10 degrees C (65% RH), 12 days at 20 degrees C (70% RH), 4 days at 30 degrees C (75% RH) and 3 days at 40 degrees C (80% RH).
