Tympanocentesis was performed in 32 pediatric patients with chronic recurrent suppurative otitis media. The aspirate was cultured aerobically and anaerobically. Aerobes were isolated from ten patients (31.2%); anaerobes from one patient; and both aerobes and anaerobes from 21 patients (65.6%). There were 46 aerobic isolates. The aerobes commonly recovered were Pseudomonas aeruginosa (24 isolates) Proteus sp. (5) and Staphylococcus aureus (3). There were 32 anaerobes isolated including anaerobic gram-positive cocci (19 isolates) and Bacteroides sp., the latter of which included Bacteroides fragilis group and Bacteroides melaninogenicus (9). The patients were treated by parenteral carbenicillin 300 to 400 mg per kg per day given in four dosages administered for a period of 12 to 21 days (average 17 days). An aminoglycoside (gentamicin) was added in 15 patients. The clinical response was good in 17 patients and poor in 15. There were no side effects or adverse reactions noted during therapy. The above findings demonstrate the polymicrobial etiology of chronic recurrent suppurative otitis media and suggest that treatment directed against the aerobic and anaerobic isolates is efficacious in more than half of the cases.

The in vitro activity of gentamicin, tobramycin, sisomicin, netilmicin, amikacin, kanamycin and streptomycin was tested simultaneously by the agar dilution method against 584 clinical isolates of gram-negative bacilli that were resistant to gentamicin and/or tobramycin. About half of the gentamicin-resistant Pseudomonas were susceptible to tobramycin but cross-resistance was virtually complete between gentamicin and tobramycin for Enterobacteriaceae. Sisomicin was much more active than gentamicin against Klebsiella, Escherichia and Citrobacter species. Only 18.9%, 27.4% and 27.9% of Klebsiella, Enterobacter and Serratia respectively were resistant to netilmicin. Amikacin was the most effective aminoglycoside with an overall resistance of 15.6%. Kanamycin was effective against 40% of Proteus and Providencia species. Surprisingly, more than half of Klebsiella and Enterobacter species and 85.3% of Serratia species were susceptible to streptomycin.

Since 1973 30 patients with urinary tract infections (UTI) or pyelonephritis have been treated with sisomicin, a new aminoglycoside, in a daily dose of 2 mg/kg for a period of seven to nine days. From a clinical point of view the result of treatment was good. Complete resolution was achieved in 17 patients, improvement in nine, and there was no effect in four patients. Thirty-five causative organisms (Escherichia coli = 23, Proteus sp. = 7, Klebsiella sp. = 3, Pseudomonas aeruginosa = 1, Citrobacter = 1) were isolated before treatment. Thirty of the organisms were eliminated during treatment, but seven reappeared during the follow-up period; five strains persisted. Side effects observed consisted of reversible increase of serum creatinine in four patients, excretion of granular casts in 14 patients, and a transient rise of alkaline phosphatase, SGOT and/or SGPT in five patients. No signs of ototoxicity or any other adverse reactions were found and local tolerance was good. In 20 patients blood samples for assay were obtained daily one hour after i. m. injection of 1.0 mg/kg. No evidence of drug accumulation in the serum was found: the mean serum concentrations one hour after injection remained between 3.4 and 3,9 microgram/ml during the entire treatment period. Sisomicin is a highly effective antibiotic for the treatment of UTI caused by gramnegative pathogens. On account of its potential toxicity however, it should be used, like other aminoglycosides, only in selected cases.

The antibacterial activities of two ureidopenicillins, azlocillin and mezlocillin, were compared with those of the alpha-carboxypenicillins, carbenicillin and ticarcillin, against a large number of gram-positive and gram-negative bacteria. All four penicillins were active against a wide range of bacteria including Pseudomonas aeruginosa, but there were differences in the antibacterial spectra and in the antibacterial effects demonstrated by the two classes of penicillins. In particular, the minimum inhibitory concentrations of azlocillin and mezlocillin against Klebsiella aerogenes and against P. aeruginosa were greatly influenced by the size of bacterial inoculum tested whereas there was no significant inoculum effect with carbenicillin and ticarcillin. In stability tests, the ureidopenicillins were inactivated rapidly by the beta-lactamases of K. aerogenes and P. aeruginosa whereas the alpha-carboxypenicillins were stable. It seems probable that the inoculum effect seen with azlocillin and mezlocillin in antibacterial tests with K. aerogenes and P. aeruginosa is associated with the instability of the compounds to the beta-lactamases of these bacteria.

In Serratia marcescens and Pseudomonas aeruginosa from clinical specimen acetyltransferase AAC-(6') IV leads to varying phaenotypically expressed resistance to aminoglycoside antibiotics. The substrate profile and the rate of inactivation of the enzymes investigated are almost identical with each other and with the enzyme of P. aeruginosa GN 315. The enzymes cannot be associated with R factors by the standard methods for conjugation, transformation, density gradient centrifugation and agarose gel electrophoresis.

The agar diffusion method was used to test the antibacterial efficacy of cefaclor against bacterial strains isolated routinely from patients in two hospitals in Berlin. A comparison was made with the efficacy of oxacillin, azlocillin, amikacin, gentamicin, ampicillin, co-trimoxazole, tetracycline, penicillin, cefazolin, nalidixic acid and nitrofurantoin. A total of 1235 strains of Staphylococcus aureus, enterococci, Escherichia coli, Klebsiella, Enterobacter, Proteus species, Citrobacter and Pseudomonas aeruginosa were tested. Cefaclor was superior to the other substances in its activity against E. coli, Klebsiellae, and Proteus mirabilis. Co-trimoxazole and tetracycline, on the other hand, proved more effective against indole-positive Proteus species and Citrobacter. Tetracycline was also more effective against Enterobacter. Ampicillin was the most effective agent against enterococci, and oxacillin the most effective against S. aureus. Cefaclor showed good antibacterial activity against strains which were resistant to the orally administrable agents ampicillin, tetracycline and co-trimoxazole.

In respiratory tract infections in children a distinction must be made between frequently recurring infections and genuine chronic infections due to specific anatomical factors, immunological defects or congenital diseases such as mucoviscidosis. The most frequent pathogens are Haemophilus influenzae, pneumococci, Staphylococcus aureus, Streptococcus pyogenes, enterococci, Pseudomonas aeruginosa and Klebsiella, S. aureus predominates in infants. The same applies for mucoviscidosis, in which P. aeruginosa is the second most frequent pathogen, occurring frequently after a primary infection with staphylococci. In order to avoid frequent relapses in mucoviscidosis patients, uninterrupted long-term treatment with an antibiotic which is effective against staphylococci is recommended, commencing the moment the diagnosis has been established. Suitable antibiotics are co-trimoxazole or oral cephalosporins (e. g. cephalexin, cephradine or cefaclor). Other respiratory tract infections should be treated according to the antibiogramme with a suitable antibiotic once the diagnosis has been confirmed.

Five heroin addicts were treated for endocarditis caused by Pseudomonas cepacia. Two of these infections occurred in patients with no known heart disease whereas the others occurred at sites of previous endocarditis or valve prostheses. Infection was indolent in four patients but was associated with shock and skin lesions suggestive of ecthyma gangrenosum in the fifth. After failure of chloramphenicol and kanamycin, all patients were treated with a combination of sulfamethoxazole, trimethoprim and polymyxin plus heart valve resection or replacement.

During the October 1973 military conflict, 41 burned patients hospitalized at the Sheba Medical Center were closely followed up. All the patients who had burns occupying 20% or more of the body surface developed wound infections. Pseudomonas aeruginosa was the major pathogen isolated. Most infections occurred during the second week following the injury. Serial cultures revealed that only the isolation of Proteus species and P. aeruginosa from wounds could predict an infection caused by those microorganisms. During treatment with gentamicin and carbenicillin a marked increase in carbenicillin-resistant P. aeruginosa and gentamicin-resistant Klebsiella strains was noted. Cross-infections with carbenicillin-resistant P. aeruginosa was not a major cause in the development of resistant strains.

Ceforanide (BL-S 786) is a new long-acting parenteral cephalosporin which has the major pharmacologic advantage of requiring only twice a day dosage. We treated 28 adult patients with community-acquired bacterial pneumonia using doses of 500 or 1000 mg every 12 hours. Twenty-four of 28 infections were due to Streptococcus pneumoniae and/or Hemophilus influenzae, and all pathogens were susceptible in vitro to both cephalothin and ceforanide. Patients were treated for a mean of 7.5 days, and all showed a good clinical and radiographic response with no mortality. Of the 13 patients with H. influenzae, the organism could still be recovered during therapy in 9/12 and post therapy in 3/8. One clinical superinfection (sepsis due to Pseudomonas aeruginosa) occurred during therapy. Side effects with therapy included thrombocytosis (15), asymptomatic eosinophilia (5), and mild elevation of the serum transaminases (3). These studies suggest that ceforanide is a safe and effective agent for the treatment of adult patients with bacterial pneumonia due to S. pneumoniae; further experience in therapy of H. influenzae is needed because of frequent failure of ceforanide to eradicate this organism from the sputum.
