title: Echinococcus granulosus: characterization of the Spanish strains using in vitro vesicular development.
abstract: Differences in in vitro vesicular development (microcyst formation) in three Spanish strains of Echinococcus granulosus (sheep-cattle, horse and pig-goat) are reported. Microcyst formation occurred in 19-37 days (sheep strain), 9-18 days (pig strain) and 35-47 days (horse strain). Comparing these results with those from human samples (microcyst formation in 24-38 days), it is possible to consider the sheep strain as the most likely source of human infections in Spain.
