Cystic fibrosis patients dating each other
Selection of these 90 patients was based on the availability of a clinical isolate in our collection.For patients who died, contribution of to mortality was determined by criteria of the Centers for Disease Control (CDC) National Nosocomial Infections Surveillance System .Infection control policies must now consider this threat of transmission between non-CF and CF patients.
Hand cultures of personnel were not studied, as survival of -based phylogenic tree was inferred by Dollo parsimony methods [7, 19].
Case-control studies of CF patients and a descriptive study of non-CF patients were done to investigate risk factors for acquisition. A retrospective chart review case-control study was performed on 20 of these patients for whom charts could be obtained.
A retrospective chart review was also done on 90 of the 245 patients without CF.
In this report, we describe the emergence of an alarming third category of outbreak that involves both CF and non-CF populations.
We used DNA-based epidemiologic typing methods to characterize the genetic relatedness of the involved isolates.
is an important pathogen in cystic fibrosis (CF) and an infrequent cause of nosocomial infection in non-CF patients.
