C. Graeff-teixeira et al., Isolation of Angiostrongylus costaricensis first-stage larvae from rodent feces on a percoll gradient, J PARASITOL, 85(6), 1999, pp. 1170-1171
Several density gradients were tested for the isolation of parasitic nemato
de, Angiostrongylus costaricensis, first-stage larvae from rodent feces. Wi
th a 45/72% Percoll gradient, 83-99% (89.56 +/- 6.57%) of the larvae were r
ecovered in a clean preparation.
