Neonatal infections.

The spectrum of neonatal infections continues to evolve with changes in the types and antibiotic susceptibilities of bacterial pathogens and the prominent appearance of new clinical syndromes of infection in the newborn intensive care unit. Fortunately with the development of new antibiotics and thorough reevaluation of older antibiotics in the neonate, effective antimicrobial therapy is still available. With the knowledge of national and local trends of infecting organisms, it is possible to select an accurate empiric antibiotic regimen for neonatal sepsis.
