Journal of Clinical Microbiology, Washington, v. 42, n. 5, p. 2345-2346, 2004.0095-1137e-1098-660Xhttp://repositorio.bc.ufg.br/handle/ri/15315We present a case of invasive pneumococcal infection in a healthy 10-month-old infant from whom Streptococcus pneumoniae serotype 23F was isolated from the blood and serotype 23B was isolated from the cerebrospinal fluid. Both serotypes were penicillin nonsusceptible. Pulsed-field gel electrophoresis analysis demonstrated that the two serotypes had distinct DNA patterns, indicating that infection did not occur as a result of capsular transformation but as a result of a mixed infection with two distinct pneumococcal serotypes.engAcesso AbertoArtigo10.1128/JCM.42.5.2345–2346.2004
