“…Worms were collected from arecoline induced purges as previously described (Gregory 1973). E. granulosus and D. caninum were identified on the testing strips but Taenia spp were submitted without preservation to a central laboratory for identification.…”

“…In Tasmania Taenia spp were not identified until 1969 and the results of an initial survey of tapeworms from dogs from all rural areas during 1969-71 were reported by Gregory (1973). This communication reports the annual results of a continuing survey of Taenia spp in rural dogs in Tasmania from 1969-70 to 1974-75 during the Hydatid Limitation Program.…”

The hydatid Limitation Program in Tasmania began in 1965 with the annual purging of dogs to identify areas of high prevalence of Echinococcus granulosus combined with a strong educational program aimed at preventing access to offal by dogs. From 1969 to 1975 aenia spp detected in dog purges were submitted for identification and changes in annual prevalences analysed for each species. Despite a significant reduction in the prevalence of E. granulosus since the beginning of the program, the control measures involved have apparently not predisposed to any significant change in the prevalence of T. ovis and T. hydatigena during the period of this survey.

“…Progress in control was monitored using the taeniafuge arecoline hydrobromide as a diagnostic agent, the best available method of diagnosis of canine echinococcosis although one of relatively poor sensitivity. Under field conditions in New Zealand and Australia, arecoline hydrobromide failed to purge more than a fifth of the dogs dosed with 3-5 mg/kg body weight (Gemmell, 1958(Gemmell, , 1968Jackson & Arundel, 1971;Gregory, 1973 Another factor that reduced the accuracy of the prevalence data was the introduction of alternative methods of administration of arecoline hydrobromide. Forbes (1961) demonstrated that, in dogs failing to respond to oral dosing, the purgative efficiency of arecoline was improved by the subsequent use of arecoline enemata.…”

SUMMARYThe factors influencing the rate of progress in Echinococcu8 granulo8u8 control in New Zealand were analysed by hydatid control area using stepwise multiple regression techniques. The results indicated that the rate of progress was related positively to initial E. granulosu8 prevalence in dogs and the efficiency with which local authorities implemented national control policy, and negatively to the Maori proportion in the local population and the number of dogs per owner. Problems in analysis of the New Zealand data are discussed and improved methods of monitoring progress in hydatid disease control programmes are described.

“…The prevalence of E. granulosus in dogs was measured using the taeniafuge arecoline hydrobromide as a diagnostic agent, the best available method of diagnosis of canine echinococcosis although one of poor sensitivity. Under field conditions in New Zealand and Australia, arecoline hydrobromide failed to purge more than a fifth of the dogsdosedwith 35mg/kg body weight (Gemmell, 1958(Gemmell, ,1968Jackson & Arundel, 1971;Gregory, 1973). Even when purgation was induced, some infected dogs retained their worm burdens (Gemmell, 1973).…”

SUMMAARYThe method of path analysis is described in detail. Application of this analytical technique in the interpretation of causal relationships in complex biological systems is demonstrated using data from an epidemiological study of echinococcosis in New Zealand. The results identified the major causal pathways determining Echinococcus granulosus prevalence in dogs, based on multiple regression analysis of a linear causal model constructed from prior biological and epidemiological knowledge.Only ethnic and sheep husbandry variables had important direct effects on prevalence in the North Island of New Zealand, with some climatic factors (maximum temperature and relative humidity) and soil porosity acting indirectly through animal husbandry practices. It is suggested that path analysis, by permitting interaction between epidemiological theory and statistical analysis, provides a valuable additional tool to epidemiologists for the study of causal relationships among variables in multivariate systems.
