The role of multiple wildlife hosts in the persistence and spread of bovine tuberculosis in New Zealand

摘要: AbstractAIM: To explore how the inclusion of multi-host dynamics affects predicted prevalence bovine tuberculosis (TB) in possums and other host species following current best practice for control TB large difficult remote areas, to identify which are responsible changes prevalence, whether can persist possum-free communities.METHODS: Multi-host models were constructed, comprising three with density-dependent population growth, disease transmission susceptible infected classes. Models parameterised two case studies concern New Zealand, namely chronic persistence a possum-deer-pig complex extensive forest, possum-pig-ferret unforested semi-arid shrub grasslands. Persistence face possum was evaluated from model simulations, contribution different hosts assessed by removing ...
