Ander: 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

Adequate dilutions of meconium and stool samples were spread onto general and selective culture media for the enumeration of different bacterial species.
Identification of isolates was carried out by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry.
