Bordetella bronchiseptica is primarily resistant against nitrofurantoin (MIC greater than 200 mug/ml), and this feature can be used for the differentiation of the organism from other gram-negative coccobacteria. Nitrofurantoin paper disks (300 mug) failed to affect the growth of 150 strains of B. bronchiseptica isolated from different animal hosts, but they produced marked inhibition zones in the cultures of the followingspecies: Pasteurella multocida, Pasteurella pneumotropica, Pasteurella haemolytica, Yersinia pseudotuberculosis, Yersinia enterocolitica, Francisella tularensis, Haemophilus influenzae, Haemophilus parainfluenzae, Brucella abortus, Brucella melitensis, Brucella suis and Brucella neotomae.

Meropenem (MEPM), a novel parenteral carbapenem antibiotic, was examined in a cooperative study involving 12 pediatric and 1 neonatologic facilities. The results are summarized as follows. 1. Antibacterial activity Antibacterial activity of MEPM against stock organisms including 31 strains of Streptococcus agalactiae, 14 of Listeria monocytogenes, 4 of Bordetella pertussis and 3 of Neisseria meningitidis ranged from 0.025 to 0.10 micrograms/ml in MIC90's, which were equal or lower than those of control drugs such as imipenem cefazolin, cefotiam, cefotaxime, ceftazidime and latamoxef. MICs against clinical isolates were as follows: In Gram-positive bacteria, MICs were 0.20 micrograms/ml to 6.25 micrograms/ml against 3 strains of Staphylococcus aureus, and 0.025 micrograms/ml or less against 4 of Streptococcus pneumoniae. In Gram-negative bacilli, MICs were 0.10 micrograms/ml to 0.20 micrograms/ml against 3 strains of Haemophilus influenzae and 0.78, 0.10 and 0.78 micrograms/ml, respectively, against one strain each of Enterobacter cloacae, Morganella morganii and Pseudomonas aeruginosa. MIC against 1 strain of Peptococcus saccharolyticus was < or = 0.025 micrograms/ml. 2. Pharmacokinetics Maximum plasma concentrations after intravenous infusion of MEPM over 30 minutes at doses of 10, 20 and 40 mg/kg, respectively, to 3 different groups of 3 children (total 9 cases) were observed at the completion of the treatment. Mean maximum concentrations in the 3 groups were 36.3, 69.5 and 129.8 micrograms/ml, respectively, exhibiting clear dose response. Mean plasma half lives in beta phase were 0.94, 0.86 and 0.94 hours, respectively, exhibiting no difference by doses, and this trend was observed also by HPLC. Urinary excretion rates in the first 6 hours after dose in the 10, 20 and 40 mg/kg groups were 67.3, 65.6 and 68.4%, respectively. Concentrations of MEPM in cerebrospinal fluid were determined in 2 cases of pyogenic meningitis. In 1 case, 500 mg (5.9 mg/kg) of MEPM was infused intravenously over 30 minutes and concentrations on Days 6, 8 and 15 observed at 190, 60 and 100 minutes after respective doses were 0.13, 0.10 micrograms/ml and less than the detection limit. Cerebrospinal fluid-plasma concentration ratio was determinable only on Day 8 and was 2.8%. In another case to which 250 mg (38.5 mg/kg) of MEPM was infused intravenously over 30 minutes, the concentration at Days 6, 7 and 10, 1 hour after the dose were less than the detection limit on day 6, and 2.04 and 2.62 micrograms/ml, respectively on days 7 and 10. 3. Clinical efficacy Clinical efficacies were evaluated in 49 cases and the efficacy rate was 93.9%.(ABSTRACT TRUNCATED AT 400 WORDS)

The in vitro susceptibilities of Bordetella pertussis and Bordetella parapertussis to seven fluoroquinolones were assessed by the agar dilution method. Ciprofloxacin and temafloxacin were the most active compounds (MIC for 90% of isolates tested [MIC90], 0.06 microgram/ml), while enoxacin and pefloxacin were the least active (MIC90, 0.5 microgram/ml). Fleroxacin, lomefloxacin, and ofloxacin showed intermediate activities (MIC90s, 0.125 to 0.25 microgram/ml). These results suggest a possible role for the fluoroquinolones in the treatment of pertussis, at least in adult patients.

Of six new oral cephalosporins, cefixime and cefpodoxime were the most active (MIC for 90% of isolates tested [MIC90], 16 micrograms/ml) against Bordetella pertussis, followed by cefetamet, cefprozil, and loracarbef (LY163892) (MIC90, 64 micrograms/ml) and ceftibuten (MIC90, 128 micrograms/ml). Against Bordetella parapertussis, loracarbef was more active (MIC90, 32 micrograms/ml) than the other compounds tested (MIC90s, 64 to greater than 128 micrograms/ml). The new oral cephalosporins are unlikely to play a role in pertussis treatment.

The in vitro susceptibilities of 1,310 clinical isolates to QA-241, a novel tricyclic quinolone, were evaluated in comparison with susceptibilities to norfloxacin, ofloxacin, enoxacin, and ciprofloxacin. The MICs of QA-241 for 90% of staphylococci, Enterococcus faecalis isolates, and streptococcal species ranged from 1.56 to 6.25 micrograms/ml, and the activity of QA-241 was similar to those of norfloxacin and enoxacin but two to four times less potent than those of ofloxacin and ciprofloxacin. At the concentration of less than or equal to 1.56 micrograms/ml, QA-241 inhibited 90% of Haemophilus influenzae, Bordetella pertussis, Neisseria gonorrhoeae, and gram-negative enteric bacteria except for Serratia marcescens and Citrobacter freundii. QA-241 was moderately active (MIC for 90% of strains tested, 6.25 to 12.5 micrograms/ml) against S. marcescens, Pseudomonas aeruginosa, Xanthomonas maltophilia, and Bacteroides fragilis. The antibacterial activity of QA-241 was roughly comparable to that of enoxacin but two to four times less potent than that of ofloxacin. In systemic infections in mice with gram-positive cocci and gram-negative rods, the efficacy of QA-241 was generally greater than that of norfloxacin and similar to those of ofloxacin and ciprofloxacin. In urinary tract infections in mice with Escherichia coli or Pseudomonas aeruginosa, QA-241 was as active as ofloxacin and more active than norfloxacin but less active than ciprofloxacin. In pulmonary infections in mice with Klebsiella pneumoniae, the effectiveness of QA-241 was similar to that of ofloxacin.

Information concerning the resistance to sulfonamides in the Netherlands was obtained by determining the minimal inhibitory concentrations (MIC's) of 119 strains of Bordetella bronchiseptica and 151 strains of Pasteurella multocida, obtained from pigs at five veterinary bacteriology centres, to sulfadimidine (SDM) and sulfamethoxazole (SMX). The MIC's of SDM against Su-susceptible strains were usually 4 times higher than those of SMX. About one third of B. bronchiseptica isolates were resistant (MIC greater than 64 micrograms/ml) to both sulfonamides. Approximately 7% of P. multocida isolates were resistant to SMX, and 21% to SDM. It is concluded that the use of SDM as the sulfonamide of choice for the treatment of atrophic rhinitis is questionable.

Cefminox (CMNX, MT-141) was studied both fundamentally and clinically in the field of pediatrics with following results. The MIC of CMNX for Bordetella pertussis was 0.10 micrograms/ml in inoculum size 10(6) cells/ml. Following administration of 10 and 20 mg/kg of CMNX as drip infusion over 1 hour, the blood levels of the drug were 49.0 +/- 18.1 and 69.1 micrograms/ml at completion of infusion, 28.8 +/- 7.7 and 61.6 micrograms/ml at 1.5 hours, 23.6 +/- 9.3 and 44.1 +/- 3.8 micrograms/ml at 2 hours and 1.4 +/- 1.4 and 4.0 +/- 0.6 micrograms/ml at 7 hours, with T1/2 of 1.03 and 1.41 +/- 0.03 hours, respectively. Within the first 7 hours after administration, 61.4 +/- 8.2 and 55.9 +/- 0.8% of the drug dosed were excreted at active form in urine. In child with encephalitis, drug considered to be good as a cephem antibiotic was achieved in the cerebrospinal fluid (the ratio of the level in the cerebrospinal fluid to that in the serum was 7.3%). In addition, in the pus in empyema also high level was reached (its ratio against blood level was 53%). In the treatment of 31 cases of acute infections of pediatric field including upper and lower airway infections, empyema, whooping cough, acute urinary tract infections and phlegmon, CMNX was administered intravenously either as one shot injection as drip infusion. The clinical results obtained were rated as good or more in 93% of the cases and as fair or more in 100% of the cases. The main dosage of CMNX in these cases was about 60 to 70 mg/kg per day in 2 or 3 divided doses. S. aureus, S. pyogenes, S. pneumoniae, H. influenzae and ABPC resistant strain of E. coli demonstrated in various materials could be eradicated after intravenous injection of CMNX. CMNX was administrated for a period of 2 to 16 days to a total amount of 1.5 to 26.5 g. In none of these cases side effects developed nor any abnormality was revealed by hematological findings or results of renal or liver function.

Clinical trial of cefoperazone (CPZ) for the treatment of whooping cough and whooping cough syndrome was performed and the following results were obtained. 1) In 18 cases suffering from whooping cough, CPZ was given 47 approximately 106 mg/kg/day (average 72 mg/kg/day) by intravenous route. The clinical efficacy rates judged by doctors in charge were 44% on the 3 rd day, 75% on the 7 th day, 86% on the period day. And in these cases, the clinical efficacy rates judged by committee members were 56%, 83% and 86%. 2) In 6 cases diagnosed as whooping cough syndrome, CPZ was given 49 approximately 96 mg/kg/day (average 59 mg/kg/day) by the same route. The clinical efficacy rates judged by doctors in charge were 67% on the 3 rd day, 80% on the 7 th day and 75% on the period day. And in these cases, those judged by committee members were 83%, 80% and 100%. 3) In 1 case, Bordetella pertussis was searched and showed 0.012 mcg/ml of MIC. It was eliminated on the 1 st day after administration. 4) Doctors in charge judged the utility of CPZ for whooping cough. Twelve cases were useful and 6 cases were slightly useful. 5) No side effects were observed except for elevation of GOT and LDH. These results suggest that CPZ might be useful drug against whooping cough.
