[Sensitivity to antibiotic combinations fo Ps. aeruginosa strains isolated from frozen bull seminal fluid].

The standard method of serial dilutions in solid nutrient media was employed to study the sensitivity of a total of 66 field strains of Pseudomonas aeruginosa isolated from deeply frozen bull semen. Used were the following combinations of antibiotics: carbenicillin with chloramphenicol (1:1), carbenicillin with neomycin (1:1), carbenicillin with kanamycin (1:1), and carbenicillin with gentamycin (20:1). The first two combinations proved inapplicable, while the remaining two antibacterial combinations of antibiotic preparations were shown to be perspective in the decontamination of semen with special reference to the presence of Pseudomonas aeruginosa. Priority is given to the carbenicillin-gentamycin combination in a 20:1 ratio.
