[Pneumonia and submaxillary cellulitis caused by B group Streptococcus in an infant].

The association of pneumonia and submandibular cellulitis in the case of group B streptococcal LOD (Late Onset Disease) is rare. Concerning the possible nosocomial infection of a 31/2 months infant the authors compare the pulmonary disease with that of the EOD (Early Onset Disease) and like other authors recommend considering GBS as the main cause of any cellulitis for an infant under 4 months.
