Resumo
The effect of bacterial nucleases on bacteria infected by DNA- or RNA-containing bacteriophages with different serogroups was studied. Bacillary RNases have a strong inhibitory effect on RNA-containing bacteriophages. It was shown that nucleases suppressed the infection process of bacteria by bacteriophages M12, f2, PP7, and QB. The minimal inhibitory concentration ranged from 0.6 to 6 μg/mL. Bacterial ribonucleases have no impact on the development of DNA-containing bacteriophages PZ-A, PZ-B, P3k, P118, and a lysogenic culture of Escherichia coli (λ) and Bacillus subtilis 168 (phi105). RNase from Bacillus pumilus did not inactivate bacteriophages Qβ and f2 in vitro and did not influence the adsorption on bacteriophages on the cell wall of the bacteria host E. coli AB301. The enzyme effect was shown at the level of bacteriophage infection of the host bacteria. Presumably, the phase between the adsorption and penetration of phage RNA into bacterial pili is the most sensitive to the effect of RNases.
