9 cases of Pseudomonas aeruginosa endocarditis are reported and the results of this study are compared with the data of the literature. The source of infection was known in 8 patients: 7 were nosocomial infections (cardiac catheterization in 5 cases, cardiac surgery in 2 cases). The diagnosis was made in 8 patients with left-sided endocarditis. In 1 patient tricuspid endocarditis was diagnosed on postmortem examination. Carbenicillin associated with an aminoglycoside antibiotic appeared to be the most effective treatment when prescribed for several weeks. 6 of 9 patients died of uncontrolled septicemia, 3 of whom underwent surgery which was twice performed because of poor hemodynamic status. In the other 3 patients drug administration was effective at first. However, a relapse occurred in these three cases compelling another effective antibiotic therapy. Surgery was peformed in these three patients. Valve cultures were negative in two cases and positive in 1. These 3 patients survived. They are still alive after a follow-up period of 2 or 3 years.

Despite the availability of numerous beta-lactam antibiotics, benzylpenicillin remains the most important beta-lactam antibiotic in the treatment of bacterial endocarditis. Penicillin alone and in combination with an aminoglycoside is effective in the treatment of endocarditis due to all streptococci, Streptococcus pneumoniae, penicillin-susceptible Staphylococcus aureus, Haemophilus aprophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Listeria monocytogenes. Oral phenoxymethylpenicillin in combination with streptomycin is effective in treating endocarditis due to viridans streptococci. Ampicillin is effective in endocarditis due to Haemophilus influenzae, H. parainfluenzae, H. paraphrophilus, Listeria monocytogenes and Escherichia coli. Oral amoxicillin with gentamicin has been used to treat enterococcal endocarditis. The penicillinase-resistant penicillins are effective in treating S. aureus endocarditis. Carbenicillin or ticarcillin in combination with tobramycin or gentamicin are used to treat endocarditis due to Serratia marcescens and Pseudomonas aeruginosa. The use of piperacillin in combination with tobramycin against P. aeruginosa endocarditis has been associated with failure and increased resistance. The cephalosporins have been used to treat endocarditis caused by susceptible organisms. There have been few data on the efficacy of the newer cephalosporins in treating endocarditis. They have been used to treat septicaemia due to susceptible organisms with good results.

A 79-year-old female developed endocarditis and meningitis due to an ampicillin-resistant, non-beta-lactamase-producing strain of Haemophilus influenzae. Carbenicillin and gentamicin therapy resulted in bacteriological and clinical cure. The mechanism of resistance of ampicillin-resistant, non-beta-lactamase-producing strains of H. influenzae is unknown.
