Gram-stained buffy-coat smears from venous and capillary blood samples in 105 children suspected of septicaemia were examined for the presence of bacteria and the results compared with blood culture isolates. Gram-positive and Gram-negative bacteria were identified in 18 venous (44%) and 19 capillary (46%) buffy-coat preparations in 41 instances where bacterial organisms were isolated from the blood cultures. It is concluded that the examination of buffy-coat smears for bacteria in children suspected of septicaemia is a useful adjunct to blood cultures and, in areas where no facilities exist for culture of blood, may be a simple and rapid method of establishing the diagnosis of bacteraemia in suspected patients.

The enhanced risk of severe sepsis following splenectomy is now well recognized in both adult and pediatric patients. Prophylactic antibiotics and bacterial vaccines have been utilized with limited success to inhibit the high morbidity and mortality. This study reports the use of glucan, a beta-1,3-polyglucose, as a nonspecific immunostimulant for postsplenectomy pneumococcal sepsis. ⋯ Splenectomy alone did not significantly decrease phagocytic function. An increased leukocytosis in response to pneumococcal infection was observed in splenectomized glucan-treated animals. Nonspecific immunostimulation appears to have significant potential as a treatment strategy against postsplenectomy infection.

Case ReportsListeriosis as a cause of maternal death: an obstetric complication of the acquired immunodeficiency syndrome (AIDS).
A case of maternal death due to Listeria monocytogenes bacteremia, with survival of the prematurely delivered infant, is presented. Lymphopenia and a Haitian origin suggest that the fatal outcome was related to the acquired immunodeficiency syndrome (AIDS). To our knowledge, this is the first recorded instance of a maternal death due to listeriosis.

A case of a north-Queensland Aboriginal child, who died of a septicaemic illness probably caused by Chromobacterium violaceum, is reported. This organism is a Gram-negative bacillus found in soil and water. Human and animal infections are very rare, but have been reported from various tropical and subtropical areas of the world. Most of these have been fatal, although survival after recognition, appropriate antibiotic therapy, and surgical intervention has also been reported.
