[Simplified diagnostic scheme for Enterobacteriaceae].

After testing 18 experimental variants against 40 reference strains belonging to different Enterovacteriaceae groups, the authors chose a multitest medium that permits concomitant testing of mobility, indol, lysinedecarboxylase and phenylalanine deaminase (MILP). In this medium, the reactions of 3734 strains belonging to the genera Escherichia, Shigella. Salmonella, Citrobacter, Klebsiella, Enterobacter, Serratia. Proteus and Providencia were concordant with the reactions in individual test media, taking as reference, in a proportion of 99.7 and 100%. The authors, associating the MILP medium to TSI agar, propose a simple scheme consisting of eight test which permits, within only 24 hours, the correct identification of the genus and sometimes of the species of cultures or isolated colonies from selective media.

[Antibiotic sensitivity of Enterobacteriaceae isolated from women vagina and uterine cervix].

UNLABELLED: Based on performed investigation in the group of 200 women treated for recurrent and chronic vaginitis and cervicitis, the characteristic of isolated microorganism was done. There were found series of drug-resistant bacteria in the vagina and uterine cervical canal in women with recurrent vaginitis and chronic cervicitis. In 42.6% of patients with diagnosed chronic cervicitis (Cervicitis chronica n = 50) Escherichia coli strains were isolated, 5% of which produced extended spectrum beta-lactamases (ES beta L). In women with recurrent vaginitis (Colpitis recidivans n = 150) Escherichia coli strains where isolated in 45.6%. Among them 4.5% produced ES beta L. Expression of beta-lactamases with broadened substrate spectrum was done in double-disc-test. CONCLUSIONS: 1. Study of antibiotic sensitivity of isolated bacteria should be a diagnostic standard in bacterial infections of uterine cervix and vagina. 2. The choice of appropriate antibiotics should take into consideration the drug-resistance mechanisms of isolated bacteria. 3. When drug-resistant bacteria are isolated, combined therapy should be applied.
