| a pathological and bacteriological abattoir survey of the reproductive tracts of merino ewes in western australia. | macroscopic examination of 487 ewe reproductive tracts from 18 different sources was made at perth abattoirs. of these, 194 were examined microscopically and 217 bacteriologically. observations were made during march to may, when ewes were not grazing oestrogenic pasture. significant lesions in ovaries or oviducts were rare. macroscopic cysts were found in the uterus or cervix of 159 ewes (32.7%). microscopic lesions, including uterine or cervical cysts and squamous metaplasia or goblet cell hyp ... | 1975 | 1180775 |
| wimmera rye grass toxicity in western australia. | outbreaks of wimmera rye grass toxicity in the south-west of western australia, and the associated distribution of wimmera rye grass parasitised by anguina sp and corynebacterium sp were investigated. between 1970 and 1974, 58 outbreaks occurred on 26 farms in sheep and cattle grazing pasture, cereal crop, stubble, screenings, or hay containing parasitised wimmera rye grass. morbidity rates up to 77% were observed. clinical signs were characterised by staggering, collapse, periods of convulsions ... | 1975 | 1220656 |

| new infection with corynebacterium pseudotuberculosis reduces wool production. | the effect of natural corynebacterium pseudotuberculosis infection on wool production and quality in sheep was examined in light of evidence that artificial c pseudotuberculosis infection causes wool production loss. a toxin elisa was used to identify sheep that had been infected with c pseudotuberculosis. greasy and clean fleece weights and fibre diameter were compared in infected and uninfected sheep. c pseudotuberculosis infection caused a 3.8 to 4.8% decrease in greasy wool production and a ... | 1994 | 8166614 |
