In vitro propagated viromes and selective phage cocktail for NEC prevention in preterm pigs
Listed in NCBI GEO
Necrotizing enterocolitis (NEC) is a severe intestinal disorder connected to a gut microbiota dysbiosis.
Description
Approximately 7-8% of very low birth weight (VLBW) infants are diagnosed with NEC with mortality rates reaching 20-50%. Fecal virome transfer (FVT) is an approach where the bacteria-free fecal fraction from a healthy donor is administered to a patient with a GM dysbiosis.
FVT contains e.g. bacteriophages, eukaryotic viruses, and metabolites. Oral administered FVT from healthy milk-fed term pigs shows promising potential in preventing NEC in the preterm piglet model. However, efficacy and safety are inconsistent between experiments.

In the current study, we aim to explore methods of creating reproducible FVT-like treatments and test if these act preventive against NEC and possess minimal side effects in the preterm piglet model. Using cesarean-delivered, formula-fed preterm pigs, we compare the NEC preventive effect of native donor fecal virome (nFV) with: 1) a defined bacteriophage cocktail targeting NEC-associated bacteria; and 2) a chemostat fecal virome propagation with lactose as the major carbohydrate source (cFV), and 3) chemostat fecal virome propagation with lactose and milk oligosaccharides (cFV-OS).
All methods will be compared to control treatment with SM buffer (SM).
