Oesophagus samples from 714 cattle from Western Australia were examined by artificial digestion to detect the presence of Sarcocystis spp. The overall prevalence of infection was 52%. The prevalence of infection increased with age and was highest in the entire males (92%). The prevalence was lower in cattle which originated from arid and semiarid regions (9 and 31% respectively) than those from tropical (87%) and temperate (60%) regions. Possible reasons for these differences are discussed and it is concluded that environmental and management factors as well as host age and sex influence the prevalence of infection with Sarcocystis spp. in cattle.
对来自西澳大利亚的714头牛的食管样本进行人工消化检查,以检测肉孢子虫属的存在。总体感染率为52%。感染率随年龄增长而升高,在所有雄性牛中最高(92%)。来自干旱和半干旱地区的牛的感染率(分别为9%和31%)低于来自热带地区(87%)和温带地区(60%)的牛。文中讨论了这些差异的可能原因,并得出结论:环境和管理因素以及宿主的年龄和性别会影响牛感染肉孢子虫属的发生率。
