Campylobacter enterocolitis in a neonatal nursery.

M A Karmali, B Norrish, H Lior

    The Journal of Infectious Diseases
    |June 1, 1984
    PubMed
    Summary

    Neonatal Campylobacter enterocolitis was likely transmitted from mothers to infants during delivery. Serotyping confirmed distinct Campylobacter jejuni strains in mothers and their infected neonates, indicating vertical transmission.

    Area of Science:

    • Medical Microbiology
    • Neonatal Infectious Diseases
    • Gastroenterology

    Background:

    • Campylobacter enterocolitis is a significant concern in neonatal care settings.
    • Understanding transmission routes is crucial for preventing outbreaks in nurseries.

    Purpose of the Study:

    • To investigate the transmission dynamics of Campylobacter enterocolitis in neonates.
    • To identify the source of infection in a cluster of four neonates.

    Main Methods:

    • Clinical case review of four neonates with Campylobacter enterocolitis.
    • Stool culture and Campylobacter jejuni isolation from neonates and mothers.
    • Lior serotyping of Campylobacter jejuni isolates to determine strain relatedness.

    Main Results:

    Related Experiment Videos

    • Four neonates in a nursery developed Campylobacter enterocolitis within five days.
    • Cross-infection or common-source infection were ruled out.
    • Three mothers harbored Campylobacter jejuni with matching serotypes to their neonates, suggesting vertical transmission during delivery.
    • Serotyping confirmed distinct strains in each neonate and matched maternal strains.
    • Neonatal Campylobacter enterocolitis presented as a benign, self-limited, nonfebrile diarrheal illness with bloody stools.

    Conclusions:

    • Maternal-to-neonate transmission during delivery is the likely source of Campylobacter enterocolitis in this nursery outbreak.
    • Campylobacter jejuni infections in neonates typically present with mild, self-resolving gastrointestinal symptoms.
    • Serotyping is a valuable tool for elucidating transmission pathways in neonatal infectious diseases.
