[Use of bacteriophages as selective factors in bacteriological diagnosis of mixed infections].

A new method is proposed for detecting aerobic and anaerobic bacteria during diagnostic culturing by exposure of mixed microorganism populations to bacteriophages. By lysing homologous bacteria, the phages facilitate the detection and isolation of associates resistant to them in pure cultures. The proposed method is compared with the selective media techniques and a conclusion is made on the advantages of selective decontamination of biological samples by bacteriophages in experiments and diagnostic culturing of material from patients with pyo-inflammatory processes.
