| Outline of Final Research Achievements |
For neonates discharged from hospital, the intestinal microbiota at one month after discharge were analyzed. In the probiotic group, the proportion of Enterobacteriaceae was significantly lower than that in the control group. The isolation rate of ESBL producing bacteria form 814 neonates admitted to our NICU was less than 1%. In addition, the isolation rate of ESBL-producing bacteria of 20 pairs of mother and newborn at an obstetrics facility was investigated prospectively. ESBL-producing bacteria was not detected from stools of mother at birth, neonatal rectal swab at 4 or 5 days after birth and for one month of age. Recently, ESBL from samples derived from adult outpatients has been isolated with a high frequency as high as 10 to 20%. In contrast, it was found that the isolation rate of ESBL-producing bacteria from perinatal and neonatal population was low.
