Autre: Probiotics supplementation
Five very low birth weight (VLBW) infants enrolled within 2 days of birth, with a weight < 1300 g and gestational age < 29 weeks and without any malformation or metabolic disease at birth were supplemented with two daily doses of a mixture of "Bifidobacterium breve" and "Lactobacillus salivarius" , probiotic strains isolated from human milk during their first weeks of life.
The lyophilized powder has contained at least 1x10^9 colony forming units (CFU) per doses of each one of the probiotic bacteria.
|
blood and fecal samples were collected from five VLBW preterms which were supplemented with a probiotic mixture of Bifidobacterium breve / Lactobacillus salivarius isolated from human milk
