Role of dietary restriction in the prevention of infection in leukaemia.

Sterilisation of the gastro-intestinal tract is believed to be important in the prevention of infection in leukaemic patients. This has been achieved by the use of isolator units, non-absorbable oral antibiotics and restriction of diet to cooked foods only. The importance of dietary restriction is examined and a comparison made of cultures taken from various foods and ward utensils. As pathogenic micro-organisms were isolated only from uncooked vegetables grown in soil, it is considered that, provided these items are avoided, general dietary restriction is of little importance in the prevention of infection in the treatment of leukaemia.
