[An outbreak of nosocomial candidiasis in a hematology ward].
The aim of the present investigation was the study of the epidemic process of hospital candidiasis. The study was carried out from October 1991 to May 1992 in a hematological ward of one of the hospitals of St.-Petersburg on 9 patients with generalized forms of candidiasis: in 4 of them the disease was caused by C. albicans and 5--by C. parapsilosis. Intestinal dysfunction as one of the first manifestations of candidosepsis caused by C. albicans, the isolation of C. albicans from feces, ulcero-necrotic colitis (established by postmortem examination), as well as the incapacity of these patients of immune response (in 2 serologically examined patients the titer of antibodies to fungi of the genus Candida was found to be lower than the diagnostic titer), were indicative of the dissemination of fungi from the gastrointestinal tract. The cases of fungemia caused by C. parapsilosis were due to the fungal contamination of vascular catheters in these patients. This infective agent was also isolated from washings obtained from the hands of nurses carrying out treatment and from medical rubber gloves. Moreover, some violations in the rules of the preparation of disinfecting solutions and the treatment of the hands of the personnel were established.

[The possibilities for using combined methods in typing Candida albicans for establishing epidemiological relationships].
An outbreak of candidiasis caused by C. albicans was registered in a neonatal intensive care unit of one of the hospital of St.-Petersburg at the period of August 12-October 8, 1992. C. albicans were isolated from 21 out of 87 patients. To achieve their more detailed deciphering and to establish epidemiological relationships, the intraspecific typing of C. albicans was carried out by DNA typing and by the electrophoretic spectrum of exoproduct proteins. The analysis of the results of this typing revealed that strains classified with the same biotype belonged to different electrophoretic groups and, vice versa, strains of the same electrophoretic group could belong to different biotypes. The analysis of the data obtained by taking into account the results of typing by the two methods, the time of the patients stay in the unit, the number of the maternity clinic from which an individual patient arrived, the number of the reanimation place and the number of the apparatus for artificial lung ventilation made it possible to establish epidemiological relationships between the patients in all cases.
