| evidence that a hydatid cyst is seldom "as old as the patient". | human hydatid disease caused by the strain of echinococcus granulosus endemic in australia and new zeland has been regarded as a very lonstanding condition, and most cysts diagnosed in adults were believed to have resulted from infection in childhood. a significant drop in the number of new cases among people and 25 and over (p less than 0.05) in two hydatid-control programmes makes it necessary to revise this view. in both tasmania (p greater than 0.50) and new zealand (0.50 greater than p grea ... | 1978 | 78222 |
| the control of hydatid disease and ovine cysticercoses in the australian capital territory and southern new south wales. | a survey of human hydatid disease in new south wales and the australian capital territory over the period 1968 to 1973 was made from hospital records in sydney and canberra. the 162 new cases found represent an incidence, of 0-57 per 100,000 per annum, but the 20 patients living in the central west statistical division of new south wales at the time of admission to hospital represent an incidence of 12-6 per 100,000 per annum in that area. a survey of a.c.t. farms revealed dogs carrying the caus ... | 1977 | 875855 |
| australasian contributions to an understanding of the epidemiology and control of hydatid disease caused by echinococcus granulosus--past, present and future. | for several years after echinococcus granulosus was introduced into australasia from europe, its life cycle was unknown. before the end of the 19th century, however, cystic hydatid disease (chd) was recognized in humans as an important cause of death, although its magnitude was not quantified. during the first 50 years of the 20th century, the urban component declined, but chd remained a serious source of ill-health. during the second half of the 20th century major research contributions have in ... | 1990 | 2210938 |
