Amikacin was evaluated in vitro by agar dilution testing against 148 different clinical isolates of cephalothin-resistant Enterobacteriaceae and Pseudomonas aeruginosa in parallel with cephalothin, cefoxitin, moxalactam, N-formimidoyl thienamycin, ceftriaxone, and cefmenoxime. Cefsulodin was also evaluated against 39 isolates of P. aeruginosa. More than 80% of all isolates tested were also gentamicin resistant, as determined by disk testing. Moxalactam and amikacin had comparable high activities against Proteus species, Escherichia coli, Serratia species, and Providencia species, and both amikacin and N-formimidoyl thienamycin had comparably high activities against the Klebsiella-Enterobacter group. N-Formimidoyl thienamycin was the most active agent against P. aeruginosa, followed by cefsulodin and amikacin.

A total of 5.584 bacterial strains of different species from urine samples of various University clinics were isolated in 1983. These were tested with regard to their susceptability towards antibacterial substances. E. coli was the most common rod bacteria isolated, followed by Proteus species, Klebsiella und Pseudomonas. Staphylococci and Enterococci were found relatively frequently. A list was set up concerning the resistance pattern of the most important gram-negative rod bacteria toward four penicillin- and three cephalosporin derivatives as well as towards gentamicin and three chemotherapeutics in a stricter sense. For the first substance group mezlocillin supplied the best results. In the second group cefotaxime was most effective. More unfavorable on the whole were the results of the three chemotherapeutics. Enterococci were inhibited most by azlocillin, mezlocillin, ampicillin and nalidixic-acid. Cefsulodin as a special Pseudomonas cephalosporin showed strong activity towards this bacterial species.

Cefsulodin, a new semi-synthetic cephalosporin, is characterized by its activity against P. aeruginosa. In this study the authors compared this new molecule with other four betalactamines, carbenicillin, ticarcillin, azlocillin and mezlocillin, and two aminoglycosides, amikacin and netilmicin. Two hundred and forty five strains studied were 100 Pseudomonas aeruginosa, 20 Acinetobacter, 42 Proteus, 21 Serratia, 22 Enterobacter, 20 Klebsiella and 20 E. coli. One hundred twenty strains of these showed carbenicillin resistant phenotype. MIC were determined by the agar dilution method. Cefsulodin was only active on Pseudomonas aeruginosa. MICs were at least 16 mg/l in the other species. On carbenicillin susceptible P. aeruginosa strains, the average MIC of cefsulodin, amikacin and netilmicin was 1 mg/l, and MICs of azlocillin, mezlocillin, ticarcillin and carbenicillin were 4-8 mg/l, 8 mg/l, 16 mg/l and 32 mg/l, respectively. On carbenicillin resistant P. aeruginosa, ticarcillin and mezlocillin were not effective and MICs of azlocillin and cefsulodin were 16 mg/l and 4-8 mg/l, respectively. However, MICs were between 64 and 128 mg/l in 20 p. cent of carbenicillin resistant strains.

Two cases of critical nosocomial pneumonia caused by flavobacterium meningosepticum (FM) were reported and both of them were successfully cured. There were 2 other cases of FM pneumonia reported in Chinese literature previously, but none of them survived. It has been found that the treatment for FM respiratory infection was very difficult because of its resistance to majority of antibiotics, including the third generation cephalosporins. The symptoms of FM pneumonia are similar to those of other gram-negative bacillus pneumonias, such as Klebsiella pneumoniae pneumonia. Definite diagnosis depends principally on etiological examination and clinical manifestations of pneumonia. Cefoperazone, Cefsulodin, Astreonam and Ciprofloxacin are valuable drugs in saving the lives of patients with FM Pneumonia.

Bacteria isolated from lower respiratory tract infections were collected in cooperation with institutions located throughout Japan since 1981, and Ikemoto et al. have been investigating susceptibilities of the isolates to various antibacterial agents and antibiotics, and the relationships between the isolates and characteristics of the patients and so forth each year. We discuss the results in detail. In 20 institutions around the entire Japan from October 1992 to September 1993, 690 strains of bacteria were isolated mainly from sputa of 549 patients with lower respiratory tract infections and presumed to be the etiological bacteria. MICs of various antibacterial agents and antibiotics were determined against 101 strains of Staphylococcus aureus, 121 strains of Streptococcus pneumoniae, 122 strains of Haemophilus influenzae, 92 strains of Pseudomonas aeruginosa (non-mucoid), 32 strains of Pseudomonas aeruginosa (mucoid), 52 strains of Moraxella subgenus Branhamella catarrhalis, 28 strains of Klebsiella pneumoniae etc., and the drug susceptibilities of these strains were measured except the strains which died during transportation. 1. S. aureus S. aureus strains for which MICs of methicillin were higher than 4 micrograms/ml (methicillin-resistant S. aureus) accounted for 61.4% and the frequency of the drug resistant bacteria was higher than the previous year's 58.3%. MICs values indicated that arbekacin was as active as vancomycin against all the strains on S. aureus. 2. S. pneumoniae Benzylpenicillin among the penicillins showed potent activities against S. pneumoniae. Cefuzonam, cefazolin, cefotaxime and cefmenoxime among the cephems showed excellent antimicrobial activities against S. pneumoniae. Imipenem; carbapenems, showed the most potent activity, and MIC80 was 0.015 microgram/ml. 3. H. influenzae All the drugs tested were potent against H. influenzae. Ampicillin among the penicillins showed MIC80 1 microgram/ml against H. influenzae. Cefotaxime, cefmenoxime, cefuzonam and cefixime showed the most potent activities, and MIC80s were 0.063 microgram/ml. The antimicrobial activity of ofloxacin was equivalent to those of cephems. 4. P. aeruginosa (mucoid) Ciprofloxacin showed the most potent activity against P. aeruginosa (mucoid), and MIC80 was 1 microgram/ml. Cefsulodin, aztreonam, carumonam and tobramycin showed the next most potent activities with an MIC80s of 2 micrograms/ml. 5. P. aeruginosa (non-mucoid) Tobramycin and ciprofloxacin showed the highest activities against P. aeruginosa (non-mucoid) with an MIC80s of 2 micrograms/ml. Norfloxacin also showed some activity, and MIC80 was 4 micrograms/ml. Comparing to activities against P. aeruginosa (mucoid), all the drugs tested showed lower activities against P. aeruginosa (non-mucoid). 6. K. pneumoniae The activities of all drugs except penicillins were high activities against K. pneumoniae. Carumonam showed the most potent activity with an MIC80 of 0.063 microgram/ml, followed by flomoxef, cefixime and cefozopran with their MIC80s of 0.125 microgram/ml. 7. M.(B.) catarrhalis Imipenem; carbapenems, showed the most potent activity against M.(B.) catarrhalis with an MIC80 0.063 microgram/ml. Minocycline and ofloxacin showed MIC80s 0.125 microgram/ml, respectively. We also investigated year to year changes in the background of patients, as well as types of respiratory infectious diseases, and the etiological bacteria. As for patients backgrounds, there were many infectious diseases found among patients in a high age bracket, and the patients over age 60 accounted for 60.8% of the diseases. The distribution by lower respiratory tract infections was as follows: bacterial pneumonia and chronic bronchitis accounted for the greatest numbers of cases with 30.4%, 29.5%, respectively, followed by bronchiectasis with 12.2%. As for frequencies of etiologic bacteria for respiratory tract infections, H. influenzae: 22.2%, and S. pneumoniae: 15.1% in chronic bronchitis; S. pneumoniae: 2
