High viral abundance as a consequence of low viral decay in the Baltic Sea redoxcline.

ABSTRACT: Throughout the Baltic Sea redoxcline, virus production and the frequency of lytically-infected prokaryotic cells were estimated from parallel incubations of undiluted seawater and seawater that contained prokaryotes with substantially reduced numbers of viruses (virus dilution approach), effectively preventing viral reinfection during the incubation period. Undiluted seawater incubations resulted in much higher estimates of virus production (6-35×104 mL-1 h-1) and the frequency of infected cells (5-84%) than the virus dilution approach (virus production: 1-3×104 mL-1 h-1; frequency of infected cells: 1-11%). Viral production and the frequency of infected cells from both approaches, however, cannot be directly compared, as data obtained from undiluted incubations were biased by viral reinfe
