Occurrence of non-fermenting Gram-negative bacteria was investigated by the Authors in various clinical specimens expecially of compromised hosts. 15 non-fermenting Gram-negative bacterial strains were isolated and identificated by two routine diagnostic systems. Isolates, were resistant to tetracycline, ampicillin, chloramphenicol and carbenicillin, while were shown to have different pattern of susceptibility to the aminoglycoside antibiotics examined.

[Etiology and rational therapy of acute otitis media in adults].

Acute otitis media (AOM) is an infection frequently found in children, but tends to be less frequent with age and its frequency in adults is only about 1%. The etiology of AOM in children is prevalently bacterial; numerous studies have shown the most common etiological agents. But the etiology in adults has not been well studied. The authors examined 40 cases of AOM in adults, the pathologic material was obtained by needle aspiration; in 32 samples there was bacterial growth. In the majority of the cases (94%) the bacteria isolated were the same as those found in children: S. pneumoniae, H. influenzae and B. catarrhalis; much rarer were S. pyogenes and S. aureus. On the potential beta-lactamase producing strains, this activity was measured. From our findings we believe that there is the necessity to have a rational antibiotic therapy (due to the difficulty in obtaining pathologic material) with active drugs for the probable etiological agents of AOM.
