title: Comparative studies between four chemicals for long-term preservation of Trichinella spiralis larvae's.
abstract: A comparative evaluation of four conservation chemicals (96% ethanol, 1% sodium benzoate, 10% formalin and glycerol), used to preserve Trichinella spiralis larvae's over 120 days, was performed. The results obtained after conservation with 96% ethanol, 1% sodium benzoate and glycerol showed no statistically significant differences in both the shape and the diameter in coiled Trichinella spiralis larvae's over the tested period. Additional advantage of glycerol as conservation liquid toward formalin is a lack of toxicity.
