A new aminoglycoside antibiotic, netilmicin, was tested against 306 clinical isolates from ill children and compared with sisomicin and gentamicin. Activity against Enterobacteriaceae was similar to that of gentamicin but less than that of sisomicin. Two gentamicin-resistant strains of Enterobacteriaceae (Klebsiella, MIC 6.25 microgram/ml, Escherichia coli, MIC 12.5 microgram/ml) were susceptible to netilimicin (MIC 3.12 microgram/ml). Netilmicin was ineffective against almost all strains of Pseudomonas but active against the majority of strains of Staphylococcus, Neisseria meningitidis and Haemophilus influenzae tested. Disc diffusion sensitivity results correlated in general with the agar dilution test. Netilmicin had little activity against Pseudomonas but may be useful in the treatment of infections due to gentamicin-resistant Enterobacteriaceae.

The in-vitro activity of flurithromycin against common respiratory tract Gram-positive (85 strains) and Gram-negative (44 strains) pathogens, and a collection of anaerobes (125 strains) was compared with that of erythromycin, cefixime, amoxycillin, co-amoxiclav, ciprofloxacin, netilmicin and clindamycin. Flurithromycin possessed the same spectrum and potency of antimicrobial activity as erythromycin. The presence of 50% human serum in the test media enhanced the activity of flurithromycin against all isolates, with the exception of Streptococcus pyogenes. Flurithromycin induced a post-antibiotic effect (PAE) that ranged from 0.25 h (Haemophilus influenzae) to 3.5 h (Streptococcus pneumoniae) for all strains tested. The presence of serum increased or diminished the duration of the PAE, depending on the strain being analysed. No interaction between flurithromycin and the other drugs tested was observed by the checkerboard technique, but when the time-kill system was used, 35 cases of synergy were noted out of 120 tests performed (29%), of which 15 (43%) were with Moraxella catarrhalis, 12 (34%) with Staphylococcus aureus, four (11%) with H. influenzae and the remainder with S. pneumoniae and S. pyogenes. Netilmicin produced most synergic interactions. Antagonism was not detected by either methods.
