Dynamics of potentially pathogenic microflora of the water and pike perch in the Volga Delta

详细

On the basis of long-term (1995–2010 and 2013–2014) microbiological monitoring of water and pike perch in the various water areas of the Volga Delta, four dominant groups of bacteria from the family Enterobacteriaceae and genera Aeromonas, Flavobacterium, and Pseudomonas were identified. The results of studies on the species composition of water microflora and fish from natural populations and artificial breeding are summarized. The prevalence of potentially pathogenic microflora in the water and fish over the indicative ones has been shown. Water temperature influences the seasonal cycles of microorganisms and their pathogenicity factors, which determine their fast adaptation to living in different ecological niches.
