Introduction: The causative agents of acute tonsillopharyngitis are viruses and bacterial flora. Treatment of acute pharyngitis is mainly local, which includes aerosols with antiseptics. Aim: Study of antimicrobial action of "Apicold oral spray" on clinical isolates of microorganisms Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans isolated from patients' oropharynx in patients. Material and methods: The effect of Apicold Oral Spray (manufactured by APIPHARMA doo) on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis, and Candida albicans in Ukrainian patients was studied. Antimicrobial activity was assessed after 5, 10 and 20 minutes of action of one dose of "Apicold oral spray" on microorganisms. Bactericidal and fungicidal action (inhibition of cell growth of microorganisms) is expressed as a percentage according to the control. Results and discussion: Apicold Oral Spray has a 100% antimicrobial effect after 5 minutes on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans (complete growth inhibition of all 5 clinical isolates after 20 minutes). Conclusion: "Apicold oral spray" has a high antimicrobial effect on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans, which is confirmed by 100% inhibition of the growth of all bacteria after 5 minutes

ABSTRACT Ceftobiprole, a broad-spectrum pyrrolidinone-3-ylidenemethyl cephem currently in phase III clinical trials, had MICs between 0.008 μg/ml and 8.0 μg/ml for 321 clinical isolates of Haemophilus influenzae and between ≤0.004 μg/ml and 1.0 μg/ml for 49 clinical isolates of Moraxella catarrhalis. Ceftobiprole MIC50 and MIC90 values for H. influenzae were 0.06 μg/ml and 0.25 μg/ml for β-lactamase-positive strains (n = 262), 0.03 μg/ml and 0.25 μg/ml for β-lactamase-negative strains (n = 40), and 0.5 μg/ml and 2.0 μg/ml for β-lactamase-negative ampicillin-resistant strains (n = 19), respectively. Ceftobiprole MIC50 and MIC90 values for β-lactamase-positive M. catarrhalis strains (n = 40) were 0.12 μg/ml and 0.5 μg/ml, respectively, whereas the ceftobiprole MIC range for β-lactamase-negative M. catarrhalis strains (n = 9) was ≤0.004 to 0.03 μg/ml. Ceftriaxone MICs usually were generally at least twofold lower than those of ceftobiprole, whereas amoxicillin-clavulanate MICs usually were higher than those of ceftobiprole. Azithromycin and telithromycin had unimodal MIC distributions against H. influenzae, with MIC90 values of azithromycin and telithromycin of 2 μg/ml and 4 μg/ml, respectively. Except for selected quinolone-nonsusceptible H. influenzae strains, moxifloxacin proved highly active, with MIC90 values of 0.12 μg/ml. Time-kill analyses showed that ceftobiprole, ceftriaxone, cefpodoxime, amoxicillin-clavulanate, azithromycin, telithromycin, and moxifloxacin were bactericidal at 2× MIC by 24 h against all 10 H. influenzae strains surveyed. Only modest increases in MICs were found for H. influenzae or M. catarrhalis clones after 50 serial passages in the presence of subinhibitory concentrations of ceftobiprole, and single-passage selection showed that the selection frequency of H. influenzae or M. catarrhalis clones with elevated ceftobiprole MICs is quite low.

In Vitro Activity

ABSTRACT The in vitro activity of ABT-773 was evaluated againstStreptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates. ABT-773 was the most active antimicrobial tested against S. pneumoniae. ABT-773 and azithromycin were equivalent in activity against H. influenzae and M. catarrhalis and more active than either clarithromycin or erythromycin.
