Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Journal of the Department of Agriculture, Western Australia, Series 4
In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …

Dunlins and western willets were collected on their winter feeding grounds at Bodega Bay and Bolinas Lagoon, California, during 1986. Six digeneans, eight cestodes, two acanthocephalans, and a new nematode were found in dunlins. Seven digeneans, two cestodes, one acanthocephalan, and the new nematode were found in western willets; four helminths including the new roundworm were common to dunlins. Thominx cecumitis sp. n. differs from other capillarid nematodes with a spinous spicule-sheath in having a short, globular vulvar appendage, peanut-shapcd eggs, a cuticular ball at the posterior tip of the body, narrow lateral alae, and a cuticular genital bursa.

Helminths are reported for the first time from ermines (Mustela erminea) and martens (Martes americana) in Washington, USA. Among 22 adult ermines, 41% were infected by one or more of five species (Taenia mustelae, Alaria mustelae, Molineus patens, M. mustelae, and Trichinella spiralis). Among 78 adult martens from three geographic localities, the prevalence was 83%. Nine species were identified (Mesocestoides sp., T. mustelae and T. martis americana, Euryhelmis squamula, M. patens, Baylisascaris devosi, Physaloptera sp., Soboliphyme baturini, and T. spiralis). Trichinella spiralis …
Summer Drenching Of Sheep : New Recommendations For High Rainfall Areas, Brown Besier, Jill Lyon
Summer Drenching Of Sheep : New Recommendations For High Rainfall Areas, Brown Besier, Jill Lyon
Journal of the Department of Agriculture, Western Australia, Series 4
'Summer drenching' has been a highly successful strategy for controlling sheep worms in Western Australia's winter rainfall regions for many years. Drenching to remove worm burdens in summer, when the risk of reinfection by worm larvae is low, is an efficient basis to year-round worm control. The Department of Agriculture recently altered its recommendations for the timing of summer drenches to take account of new findings regarding the survival of worm larvae over summer. It now recommends that sheep farmers give the first summer drench when the pasture is beginning to dry off, in spring in most locations. Experiments atMt …
New Approach To Control Of Drench-Resistant Sheep Worms On Farms, Di Hopkins
New Approach To Control Of Drench-Resistant Sheep Worms On Farms, Di Hopkins
Journal of the Department of Agriculture, Western Australia, Series 4
Worms cost the Western Australian sheep industry up to $120 million every year, and anthelmintic (drench) resistant worms account for an increasing proportion of this amount. Resistant strains of sheep worms have been found on about 95 per cent of farms tested. This alarmingly high level indicates that all farmers should have a resistance management strategy which includes having a resistance test done on their farms before they drench their sheep. However, only about 20 per cent of farmers have had a resistance test done. Farmers often believe drench resistance is not a problem on their farms, mainly because production …
