Fish pathogenic Aeromonads (Aeromonas salmonicida, A. hydrophila, A. sobria etc) are widely distributed in fresh and brackish waters worldwide, causing disease outbreaks in cultured fish that are difficult to control. Several freshwater fish ponds were sampled in Western and Central parts of Georgia for isolation of fish pathogenic bacteria. In 2012-2015 seasonal samplings were also conducted in the Black Sea estuaries and lakes in Tbilisi surroundings. Obtained presumptive Aeromonas isolates were identified using special algorithm, based on thirteen biochemical parameters, with confirmation by API20NE system and species - specific PCR. The antibiotic susceptibility was determined by disc-diffusion method. Isolation of bacteriophages from environmental samples, their propagation and screening was done by standard techniques. From fish ponds 34 Aeromonas spp. isolates were collected and 208 – from other water bodies. Eight Aeromonas species were revealed with A.hydrophyla,A. sobria and A. salmonicida prevalent among sick fish isolates. Majority of Aeromonas spp. isolates showed multiple resistance to antibiotics with highest sensitivity to ciprofloxacin and kamamycin. Tventy Aeromonas spp.- specific bacteriophages were obtained from different water samples, using selected set of host strains of A.hydrophila, A.caviae, A.salmonicida and A.media. Twelve selected bacteriophages were characterized by virion morphology and DNA restriction profiles. Phage spot test done on set of 68 Aeromonas spp. isolates revealed diversity of lytic reactions, with 64.7% of strains lysed by at least one phage. Considerably high susceptibility (76.5%) was observed for fish farm strains. Four selected Ahy and Asa phages were tested for antibacterial activity in the microcosm experiments mimicking natural aquatic systems. The performed study is a part of a larger project aimed at creation of the research collection of bacteriophages lytic to fish pathogenic bacteria, including Aeromonas spp , to be used as a reserve pool for tailoring therapeutic phage preparations for particular fish farms experiencing outbreaks of bacterial infections.
