Epidemiological analysis of Klebsiella infections at a neonate department.
At the Department of Obstetrics and Gynaecology of a Brno hospital, 133 Klebsiella strains were isolated from 23 mothers and 58 neonates during a period of increased incidence of Klebsiella and 73 strains were examined in the laboratory. The control group was comprised by 78 Klebsiella strains isolated at three other Brno hospitals. Four prevailing Klebsiella types were identified using bacteriocinotyping and phagotyping. Different bacteriocinotypes and phagotypes were found to prevail at certain intervals both at the examined clinic and in control patients from Brno hospitals. The findings suggest circulation of certain Klebsiella types and their introduction to hospitals. Most infants (37 out of 45, i.e. 82%) were colonized by Klebsiella, their mothers remaining without colonization. The factors influencing the onset and transmission of nosocomial infections in infants are discussed.
