Abstract

Tissues from two bighorn sheep fetuses and four neonatal bighorn sheep lambs were examined for evidence of natural Protostongylus infection occurring by the transplacental route. Forty-three third-stage larvae (L₃) were recovered from the fetal liver of case 1; one L₃ from the cotyledons of case 2; 189 L₃ from the liver and 46 L₃ from the lungs of case 3; 146 La from the liver and 43 L₃ from the lungs of case 4; and 133 L₃ from the liver and 33 L₃ from the lungs of case 5. Fifty-two L₃ and fourth-stage larvae (L₄) were recovered from the lungs and five L₃ from the liver of case 6. Digestion with Pepsin-HCL was a more effective method for recovery of L₃ than baermannization, but L₄ larvae were digested.
