[Asymptomatic and manifest forms of listeriosis in neonates].

Pointed out has been a danger of listeria monocytogenes infections, which is most frequently transplacentally transmitted from the mother to the baby. In such cases, it results in early, septic forms with disseminated abscesses and granulomas in many organs. A case with a positive outcome has been described. Infection incited during delivery or soon after it results in late, meningitic form of listeriosis, which is characterized with a high mortality outcome. Such a case that resulted in death has also been described. Three children infected by listeria remained asymptomatic. Pointed out has been the inevitability of antibiotic treatment of such children, too, to prevent listeria from developing septic meningitic form. Imperative to prevent nosocomial listeria infections in obstetric wards, which is a reality, are strict measures of hygiene.
