摘要: Abstract AIM: To determine the effect of fertility control on rate transmission bovine tuberculosis (Tb), caused by Mycobacterium bovis, in brushtail possums (Trichosurus vulpecula). METHODS: At two study sites with a history Tb infection resident possum population, sample adult male and female (n=50), determined palpation to be Tb-free, was surgically sterilised gonadectomy. A untreated Tb-free (n=54) served as controls. Each site trapped every 2 months over 3-year period, status individuals trial assessed. conclusion trial, all remaining experimental were killed, necropsied examined for characteristic lesions typical Tb. The estimated using incidence tuberculous cases animals comparing it between sites, sex sterilisation treatment. RESULTS: Sterilisation gonadectomy resulted reduc...
