We have examined the bedsheets, floor and bedside chairs of 33 patients with urinary tract infections for organisms causing urinary infection. In ten patients the causative organism was recovered from the undersheet, and in two of these it was also recovered from the floor and bedside chair. Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae and Enterococcus faecalis were recovered from sheets, while Group B β-haemolytic streptococci and Candida tropicalis were also found on floors and chairs.
