[Primary peritonitis in children].

Primary peritonitis occurs rarely in childhood. The causative microbe is usually either streptococcus or pneumococcus. However, the incidence of gram negative anaerobic bacteria is increasing. The bacteria are cultured from fluid taken from the abdominal cavity during celiotomy. The abdominal viscera are normal, which excludes secondary peritonitis. We discuss the case of an infant who presented this disease entity.
