Neonatal meningitis caused by atypical Streptococcus pneumoniae:Case report and reviewStreptococcus pneumoniae is a rarely recognized cause of neonatal sepsis and/or meningitis, but it is associated with substantial morbidity and mortality.Traditionally, S. pneumoniae is identified in the laboratory by demonstrating susceptibility to optochin.However, the emergence of optochin-resistant organisms makes definite identification difficult when only phenotypic tests are taken as markers.We present the case of a severe early-onset neonatal meningitis due to an atypical strain of S. pneumoniae.Laboratory methods utilized to certify this species diagnosis are discussed.
