Abstract
We compared three preparation techniques for critical point drying of fungus Paecilomyces lilacinus Thom Samson with Toxocara canis Werner Johnston and Taenia hydatigena Linneo eggs by scanning electron microscopy We evaluated filtration first centrifugation second and phytoplankton network third in critical point drying methods The first and third methods were advantageous for T canis eggs because they preserved the quantity and quality of samples to obtain better images definition The best technique for T hydatigena eggs was the addition of phytoplankton network in critical point drying which preserved these helminth eggs
