Neisseria subflava bacteremia in newborns: case report and review of the literature

Neisseria subflava belongs to Neisseriaceae family, is considered a comensal specie, however in certain host, mainly inmunosuppresed patientes and children, the literature has documented invasive infections. We present a case of a bacteriemia due to N. subfldva in a newborn, treated with cefotaxime with good outcome. In newborns, the most common Neisseria bacteria to cause invasive infections are N. meningitidis, with highly fatal clinical course and N. gonorrhoeae which compromise the eye, oftalmia neonatorum, with uncommon invasive infections. It's very important the adequate microbiological diagnosis because the biochemical tests may be inconclusive. MALDITOF mass spectrometry technique is a useful tool.
