    “…RESULTS: The abundance of bacteria, heterotrophic (HNF) and autotrophic (ANF) nanoflagellates and ciliates, as well as bacterial production (BP) and metabolically active cells of bacteria (CTC, NuCC, EST) were studied in eutrophic lakes (Mazurian Lake District, Poland) during spring. The studied lakes were characterized by high nanoflagellate (mean 17.36 ± 8.57 × 10(3) cells ml(-1)) and ciliate abundances (mean 59.9 ± 22.4 ind. ml(-1)) that were higher in the euphotic zone than in the bottom waters, with relatively low bacterial densities (4.76 ± 2.08 × 10(6) cells ml(-1)) that were lower in the euphotic zone compared to the profundal zone. …”
