Hypothesis
The study aims to analyze the bacterial diversity in feces of breast-fed infants and compare it with that of formula-fed infants.
Conclusion
S. epidermidis is a differential trait of the fecal microbiota of breast-fed infants, with low virulence determinants and high antibiotic sensitivity.
Supporting Evidence
- S. epidermidis was found in 86.05% of fecal samples from breast-fed infants.
- S. epidermidis was present in all breast milk samples.
- Enterococcus faecalis was the second most common species in breast-fed infants' feces.
- Breast-fed infants had lower bacterial counts compared to formula-fed infants.
- All enterococcal isolates were sensitive to vancomycin.
Takeaway
Breast-fed babies have a different mix of bacteria in their poop compared to formula-fed babies, mainly having more of a good bacteria called S. epidermidis.
Methodology
The study involved collecting fecal and breast milk samples from 23 women and their infants, followed by bacterial isolation and genetic profiling.
Potential Biases
Potential bias in participant selection as only healthy women and full-term infants were included.
Limitations
The study's sample size is relatively small and may not represent the broader population.
Participant Demographics
23 women (16 breast-fed and 7 formula-fed) and their respective infants.
