In a survey designed to determine the prevalence of Bacillus cereus in the faeces of healthy persons, the organism was found in low numbers in 100 (14%) of single faecal specimens from 711 adults in the general population. In addition, in an attempt at assessing the changes in the B. cereus distribution within the faecal flora of the individual, weekly faecal specimens were submitted over a seven-week period by 18 members of staff of two laboratories. The total isolation rate was again 14%, with 15 serotypes represented. In four individuals B. cereus was isolated in two consecutive weeks and in all cases the isolates were of different serotypes. Excretion was never recorded for more than two consecutive weeks. These findings probably reflect the intake of B. cereus in the individual's diet.
在一项旨在确定健康人群粪便中蜡样芽孢杆菌患病率的调查中,从普通人群的711名成年人的100份(14%)单一粪便标本中发现了少量该菌。此外,为了评估个体粪便菌群中蜡样芽孢杆菌分布的变化,两个实验室的18名工作人员在七周时间内每周提交粪便标本。总分离率再次为14%,有15种血清型。在4个人中,连续两周分离出蜡样芽孢杆菌,且所有情况下分离株的血清型都不同。排泄从未连续记录超过两周。这些发现可能反映了个体饮食中蜡样芽孢杆菌的摄入情况。
