|
Which parasitic pneumonia of sheep/goats is described:
- most common lungworm of sheep/goats - Produce live larvae - Associated w/snails in OR - usu mild dz - more pathogenic in sheep/goats |
Muellerius capillaris - most common lungworm of sheep/goats
Dictyocaulus filaria - Produce live larvae M. capillaris - Associated w/snails in OR Protostrongylus rufescens - usu mild dz M. capillaris - more pathogenic in sheep/goats |
