[Isolation by uroculture of bacterial flora from ambulatory patients].

In the out patients investigated between 1974 and 1977 a number of 14046 quantitative urocultures were performed; 2206 (15.5%) gave relevant results for a diagnosis of urinary infection. In 98.5% of the cases, infection was caused by Gram negative bacilli, particularly Enterobacteriaceae (98.14%). A set of 11 biochemical tests, performed in a single stage, was used, correctly establishing the genus and in most cases also the species, thus realizing marked economy of material and work. It is considered that the taxonomic listing by this set is sufficient for a diagnosis of urinary infection. In such cases the clinical interest and testing the sensitivity of the strains to antibiotics is of greater importance than determination of the serotype, lysotype or biotype, of prevalent interest in other types of infection produced by enterobacteria, particularly those known to be pathogens.

[Recent proposals for nomenclature and classification of Enterobacteriaceae].

The authors review recent proposals concerning the taxonomy and nomenclature of Enterobacteriaceae, underlining the differences with respect to the classification in Bergey's Manual of Determinative Bacteriology, 8th edition. The comments are accompanied by tables showing the various more practical tests used for differentiating the taxonomic groups up to species levels.

Susceptibility to bacteriophages of Staphylococcus aureus strains received at the National Reference Centre for Staphylococci in Romania 1978-1992.

In order to determine the distribution among lytic groups of Staphylococcus aureus strains circulating in Romania 18,539 strains were phage typed in the National Reference Centre for Staphylococci between 1978 and 1992. Strains susceptible to group II phages prevailed, representing 28.28% of all phage typed strains. The distribution on lytic groups differed in terms of the type of the clinical isolate. The results are statistically analysed and compared with those obtained in Romania by Popovici et al. between 1966 and 1978 as well as with those reported for other geographical areas by other authors.
