[Pathogenicity factors of melanin-forming strains of Pseudomonas aeruginosa].

The data on the capacity of 50 melanogenic and 50 amelanogenic P. aeruginosa strains to produce hemolysins, gelatinase, caseinase, DNAase, RNAase, lecithinase, elastase, neuraminidase and to form extracellular slime, obtained in the comparative study of these strains in vitro, are presented. Melanogenic P.

[Gentamycin activity in combination with etonium in relation to Pseudomonas aeruginosa].

Gentamicin is one of the most effective drugs for treatment of infections caused by Ps. aeruginosa. However, isolation of the strains resistant to the antibiotics was not infrequent.

[Sensitivity to doxycycline (vibramycin) of the microflora isolated from the patients in a therapeutic clinic].

Sensitivity of microflora to tetracycline, oxytetracycline, chlortetracycline and doxycicline was studied. A total of 237 pure cultures of Strep. viridans (54), beta-hemolytic streptococci (27), pathogenic staphylococci (52), non-pathogenic staphylococci (53) and Coli bacteria (51) were tested with the agar-diffusion method using standard discs.
