1) Yes
2) No
3) Cannot be determined

Answer 1

1) Yes, babies born by c-section are colonized by a different set of microbes than babies born vaginally.

Step-by-step explanation:

Yes, babies born by c-section are colonized by a different set of microbes than babies born vaginally. When born vaginally, babies are predominantly colonized by vaginal lactobacillus.

However, babies born by c-section are more frequently colonized by microbes of the normal skin microbiota, including common hospital-acquired pathogens.
