Viral and bacterial abundances were determined in various habitats (water, sediments, soil, leaves) within a northeastern Ohio catchment. Viral densities ranged from 1.98 to 2.02 x 10(7)/mL in water and from 1.65 to 6.68 x 10(8)/g AFDM in :particulate samples; their abundance was not correlated with bacterial abundance. Bacterial numbers were typical for similar lotic habitats with means of 1.63 x 10(6)/mL for water, 5.79 x 10(8) and 1.09 x 10(9)/g AFDM for sediments and leaves, respectively. The virus to bacterium ratio was highest in water and lowest on leaves.
