Current evidence from systematic review and meta- analysis revealed that probiotics are the most promising intervention in reduction of the incidence of NEC in VLBW neonates .
As per the evidence , prebiotics modulate the composition of human intestine microflora to the benefit of the host by suppression of colonization of harmful microorganism and /or the stimulation of bifidobacterial growth , decreased stool viscosity , reduced gastrointestinal transit time , and better feed tolerance .
Necrotizing enterocolitis ( NEC ) is one of the most serious gastrointestinal emergencies in very low birth weight ( VLBW ) preterm neonates , affecting 7 - 14 % of these neonates .
Due to the seriousness of the disease , prevention of NEC is the most important goal .
Quantitative Real-Time PCR Assays To Identify and Quantify Fecal Bifidobacterium Species in Infants Receiving a Prebiotic Infant Formula
ABSTRACT A healthy intestinal microbiota is considered to be important for priming of the infants ' mucosal and systemic immunity . Breast-fed infants typically have an intestinal microbiota dominated by different Bifidobacterium species . It has been described that allergic infants have different levels of specific Bifidobacterium species than healthy infants . For the accurate quantification of Bifidobacterium adolescentis , Bifidobacterium angulatum , Bifidobacterium bifidum , Bifidobacterium breve , Bifidobacterium catenulatum , Bifidobacterium dentium , Bifidobacterium infantis , and Bifidobacterium longum in fecal sample s , duplex 5′ nuclease assays were developed . The assays , targeting rRNA gene intergenic spacer regions , were vali date d and compared with conventional PCR and fluorescent in situ hybridization methods . The 5′ nuclease assays were subsequently used to determine the relative amounts of different Bifidobacterium species in fecal sample s from infants receiving a st and ard formula or a st and ard formula supplemented with galacto- and fructo-oligosaccharides ( OSF ) . A breast-fed group was studied in parallel as a reference . The results showed a significant increase in the total amount of fecal bifidobacteria ( 54.8 % ± 9.8 % to 73.4 % ± 4.0 % ) in infants receiving the prebiotic formula ( OSF ) , with a diversity of Bifidobacterium species similar to breast-fed infants . The intestinal microbiota of infants who received a st and ard formula seems to resemble a more adult-like distribution of bifidobacteria and contains relatively more B. catenulatum and B. adolescentis ( 2.71 % ± 1.92 % and 8.11 % ± 4.12 % , respectively , versus 0.15 % ± 0.11 % and 1.38 % ± 0.98 % for the OSF group ) . In conclusion , the specific prebiotic infant formula used induces a fecal microbiota that closely resembles the microbiota of breast-fed infants also at the level of the different Bifidobacterium species
