In studies included in this meta- analysis , probiotic administration was associated with a reduction in NEC-related mortality
Aim of the study Probiotic administration to preterm infants has the potential to prevent necrotising enterocolitis ( NEC ) .
Data from r and omised controlled trials ( RCT ) are conflicting but meta-analyses seem to support this intervention .
To date , these analyses have not focused on surgical NEC .
We aim ed to determine the effect of probiotic administration  to preterm infants on prevention of surgical NEC .
Effects of Bifidobacterium lactis Bb12 Supplementation on Intestinal Microbiota of Preterm Infants: a Double-Blind, Placebo-Controlled, Randomized Study
ABSTRACT The gastrointestinal microbiota of preterm infants in a neonatal intensive care unit differs from that of term infants . In particular , the colonization of preterm infants by bifidobacteria is delayed . A double-blind , placebo-controlled , r and omized clinical study was performed on 69 preterm infants to investigate the role of Bifidobacterium lactis Bb12 supplementation in modifying the gut microbiota . Both culture-dependent and culture-independent approaches were used to study the gut microbiota . Bifidobacterial numbers , determined by fluorescence in situ hybridization , were significantly higher in the probiotic than in the placebo group ( log10 values per g of fecal wet weight : probiotic , 8.18 + 0.54 [ st and ard error of the mean ] ; placebo , 4.82 + 0.51 ; P < 0.001 ) . A similar trend for bifidobacterial numbers was also obtained with the culture-dependent method . The infants supplemented with Bb12 also had lower viable counts of Enterobacteriaceae ( log10 values of CFU per g of fecal wet weight : probiotic , 7.80 + 0.34 ; placebo , 9.03 + 0.35 ; P = 0.015 ) and Clostridium spp . ( probiotic , 4.89 + 0.30 ; placebo , 5.99 + 0.32 ; P = 0.014 ) than the infants in the placebo group . Supplementation of B. lactis Bb12 did not reduce the colonization by antibiotic-resistant organisms in the study population . However , the probiotic supplementation increased the cell counts of bifidobacteria and reduced the cell counts of enterobacteria and clostridia
