Representatives of the families Vibrionaceae and Aeromonadaceae are widespread in marine and freshwater environments, on the surface layer of water and in depth, in the form of free-living populations as well as with algae and dendrites associations. In 2006-2010 the monitoring mission was conducted regarding the Black Sea coast of Georgia and freshwater reservoirs: Lisi Lake, Tbilisi Sea and Lake Kumisi. The goal of the above mentioned study was to isolate and identify Vibrio spp. and Aeromonas spp. from Georgian aquatic environment, as well as the study of biodiversity. In total, 2092 isolates were isolated from Georgian aquatic environment; out of which 1869 were identified as Vibrio spp. and 223 – as Aeromonas spp. Biochemically identified 70-100% of the clinical Vibrio spp. were confirmed by PCR analysis. Also, the following 11 species of clinical Vibrio spp. were revealed from Georgian aquatic environment: V. parahaemolyticus, V. cholera, V. vulnificus, V. alginolyticus, V. metschnikovii, V. cincinnatiensis, V. holisae, V. damsel, V. fluvialis, V. harveyi, V. mimicus; 8 species of nonpathogenic Vibrio spp. – V. orientalis, V. marinus, V. pelagius, V. campbellii, V. splendidus, V. nereis, V. nigripulchritudo, V. natriegens; and 8 species of Aeromonas spp.: A. salmonicida, A. hydrophila, A. caviae, A. media, A. veronii, A. schubertii, A. sobria, A. eucrenophila were revealed. Biodiversity, quantitative and seasonal distributions of the above mentioned species were studied. The results showed that the best seasons for Vibrios spp. is autumn and summer, whereas for Aeromonas spp. it is autumn and spring.
