There is no integration of the viral genome into the host genome during the lytic cycle. The viral genome fuses with the host genome during replication of the lysogenic cycle and remains there until the lytic cycle is initiated.

In the lytic cycle, viruses produce new copies of themselves inside a host cell before bursting outside the cell. The viral genome is incorporated into the host cell's DNA during the lysogenic cycle, causing internal infection.

Bacterial cells with lytic phages are split open (lysed) and destroyed following an instant virion multiplication. Once the cell has been eliminated, the phage offspring can start looking for new victims to infect.

The host cell is not immediately lysed as is the case with the lysogenic cycle. Temperate phages are those that can go through lysogeny. Their viral genome will merge with host DNA, proliferate along with it in a relatively benign manner, or even take root as a plasmid.

In the 1980s, Drs. Barry Marshall and Robin Warren proposed the hypothesis that the bacterium Helicobacter pylori (H. pylori) are the cause of stomach ulcers. At the time, it was widely believed that stress and diet were the main causes of stomach ulcers. However, Marshall and Warren had observed that many ulcer patients had H. pylori in their stomachs and that the bacterium seemed to be associated with the development of ulcers.

To test their hypothesis, Marshall and Warren performed a series of experiments. They cultured H. pylori from the stomachs of ulcer patients and then treated the patients' ulcers with antibiotics that targeted the bacterium. They found that the antibiotics were effective in eliminating H. pylori and healing ulcers. They also showed that H. pylori infection could be transmitted from person to person.
