Results Complications of deep white candidiasis infection inside the hospital mostly took place among patients suffering from chronic respiratory diseases, malignant tumors and nosohemia,accounting for 59.09%.Infection was in direct proportion with the length of hospitalization.The chief factor leading to infection was the long-term use in large doses of wide-spectrum antibiotics,especially the use of the third-period cephalosporins,which are wide in spectrum and strong in killing bacteria.White candidiasis infection results from the composite action of multiple dangerous factors. Ofthose infected,40.91%used hormone and 11.36% used immunosuppressive agents as well as radiotherapy and chemotherapy. The application of trauma examination and curing also created conditions for the occurrence of infection.
