The faecal carriage rates of different species of Proteeae were assessed in studies with 220 faecal isolates from 219 individuals of whom approximately one-third were well and the remainder had gastro-enteritis. As a result of the development of new media that allowed replacement of the phenylalanine deaminase test with the tryptophan deaminase test and made it possible to combine tests for indole and urease production and for hydrogen sulphide and ornithine decarboxylase formation in two single-tube tests, all strains were speciated with speed, economy and accuracy. Most (96%) isolates were either Proteus mirabilis (62%) or Morganella morgani (34%). The significance of these findings in relation to urinary tract infection is discussed. P. vulgaris was found in only one (0.45%) faecal specimen and this rarity of carriage in faeces is believed to be the main reason for its rare association with urinary tract infections. The frequent association of M. morgani, in the absence of other enteropathogenic bacteria, with severe gastroenteritis was noted with interest.
在一项研究中，对来自219名个体的220份粪便分离株进行了评估，以确定不同变形杆菌属物种的粪便携带率。其中约三分之一的个体健康，其余个体患有肠胃炎。由于开发了新的培养基，使得可以用色氨酸脱氨酶试验取代苯丙氨酸脱氨酶试验，并能够在两个单管试验中同时进行吲哚和尿素酶产生试验以及硫化氢和鸟氨酸脱羧酶形成试验，所有菌株都能快速、经济且准确地进行鉴定。大多数（96%）分离株要么是奇异变形杆菌（62%），要么是摩根摩根菌（34%）。讨论了这些发现与尿路感染的相关性。普通变形杆菌仅在一份（0.45%）粪便标本中被发现，粪便中这种携带率极低被认为是其与尿路感染罕见关联的主要原因。有趣的是，在没有其他肠道病原菌的情况下，摩根摩根菌经常与严重肠胃炎相关联。
