Comment: Gram-negative septicemia is considered the cause of death. Rarely, 

 gram-negative bacilli were found in nonulcerated areas of acute dermatitis, 

 strongly suggesting hematogenous dissemination of the bacteria. Several of the 

 skin lesions were consistent with cutaneous infarcts. We believe that the 

 majority of cutaneous lesions were caused by septicemia. Ciliated protozoa were 

 found in some of the cutaneous lesions. This is a relatively common finding in 

 dolphins; these protozoa are generally considered to be secondary invaders. The 

 cause of the pulmonary necrogranuloma was not apparent; this lesion was not likely 

 to have been clinically significant. The pulmonary congestion and edema were
