INFECTIONS in the newborn due to Pseudomonas aeruginosa (Bacillus pyocyaneus) are well recognized, yet surprisingly few cases are reported. The organism is presumably highly virulent for the newborn, infections usually being fatal if generalized sepsis occurs. According to Schultz,1 the septic state is characterized by a tendency to hemorrhage and diarrhea.

An idea of the incidence of septicemia caused by this organism may be gained from the report of Dunham2 who studied 39 cases of septicemia in the newborn and found only 1 case caused by Ps. aeruginosa. More recently, Kerby3 reviewed the literature and reported 39 cases of Ps. aeruginosa septicemia in children. He concluded from his study that the source of the organism in many cases was the gastrointestinal tract.

Reports of this organism's isolation in other infections, such as meningitis, endocarditis and diarrhea, are to be found.4
