unexpected occurrence of haemonchus placei in cattle in southern western australia.haemonchus placei is an abomasal parasite of cattle, primarily in tropical and subtropical areas of the world. in australia, this nematode can be extremely pathogenic in summer rainfall areas, particularly in the hot, sub-tropical kimberley region, in the far north of the state of western australia (wa). although cattle are occasionally transferred to southern parts of wa, it was believed that h. placei did not occur in southern regions of wa, as it is less cold-adapted than haemonchus contortus ...201424189197
the ecology of haemonchus contortus in a winter rainfall climate in australia: the survival of infective larvae on sites near albany, on the south coast of western australia, sheep faecal pellets containing either eggs or infective larvae (l3) of haemonchus contortus were deposited onto natural pasture plots at intervals over 3 years. faecal and pasture samples were collected periodically and processed to detect l3. on annual pasture plots, l3 were recovered for from 10 to over 20 weeks from depositions made between autumn and early spring, at which time temperatures were mild or low, rainfall was frequen ...19938447071
the ecology of haemonchus contortus in a winter rainfall region in australia: the development of eggs to infective larvae.the seasonal pattern of development of haemonchus contortus eggs to infective larvae was investigated on the south coast of western australia. sheep faeces containing h. contortus eggs were deposited on pasture plots at intervals over a 3-year period, and pasture grass and faeces were sampled periodically for infective larvae (l3). the maximum recoveries occurred in late autumn and in late spring, when adequate moisture coincided with warm temperatures. larval development was low and sporadic ov ...19938447070
