Hospital outbreaks with yeasts.

Five previous outbreaks of disseminated candidosis due to Candida albicans are reviewed and a new outbreak on a neonatal unit in Belfast presented. This involved four disseminated cases. The control and definition of outbreaks by morpho-, immunoblot- and DNA-typing is discussed. An outbreak of Torulopsis glabrata infection involving 23 patients is described. This was defined by DNA fingerprinting with the enzyme Xba. There were five deaths attributable either completely or in part to the yeast infection.
