title: Orbital cellulitis and sinusitis caused by group B beta streptococcus in a 3-year-old child.
abstract: This paper reports a case in which an odontogenic infection extended into a maxillary sinus in an otherwise well 3-year-old child. The resulting sinusitis and orbital cellulitis were caused by an organism which does not usually cause disease in this age group, group B β-hemolytic streptococcus.
