The effect of splenectomy on pulmonary infection in newborn mice

Overwhelming postsplenectomy infection is a widely discussed and studied problem. The route of infection, the specific organisms involved, and the age at splenectomy and bacterial challenge are crucial factors in determining the genuine threat of the disease. We studied Staphylococcus aureus respiratory infection in 10-day-old mice who had undergone splenectomy or sham operation 7 days earlier. We did not find an increase in fatal staphylococcal pneumonitis under these conditions. Further laboratory definition of this complex issue is warranted.
