WebA bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material. Phage genomes can consist of either DNA or RNA, and can contain as few as four genes or as many as several hundred. 1, 2, 3. ^ {1,2,3} 1,2,3. WebPhagocytosis of bacteria by human neutrophils takes on average nine minutes to occur. Once inside the phagocyte, the bacterium is trapped in a compartment called a phagosome. Within one minute the phagosome merges with either a lysosome or a granule, to form a phagolysosome.
