Summary
Probiotic sepsis is a rare complication in preterm infants, with most cases recovering after antibiotic or antifungal treatment. This review highlights the need for surveillance and alternatives to probiotics.
Area of Science:
- Neonatal medicine
- Microbiology
- Clinical research
Background:
- Probiotics can reduce necrotizing enterocolitis, late-onset sepsis, mortality, and improve feeding in preterm infants.
- Concerns about probiotic-associated sepsis hinder widespread probiotic use in preterm infants.
Observation:
- A systematic review of 16 reports identified 32 preterm infants with probiotic sepsis.
- Most affected infants were born before 32 weeks gestation.
- Bifidobacterium, Lactobacillus, and Saccharomyces were the most common causative agents.
Findings:
- Probiotic sepsis is a rare event in preterm infants.
- Genomic analysis confirmed the administered probiotic strain in 25 out of 32 cases.
- Two neonatal deaths were reported; most infants recovered after antibiotic or antifungal treatment.
Implications:
- Optimal surveillance and treatment protocols for probiotic sepsis are crucial.
- Research into alternatives like postbiotics is warranted.
- Despite rarity, probiotic sepsis remains a concern for prophylactic probiotic use in preterm infants.

Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
