The human body lives in symbiosis with bacteria making up the human microbiome. These bacteria are normally present in human organisms and have beneficial effects in our physiology. However, pathogenic bacteria can cause infection and lead to disease. Some bacteria have been linked to certain types of cancer, e.g. Helicobacter pylori and gastric cancer.

They show high selectivity for infecting malignant tumor cells and could provide better outcomes for patients who do not respond well to conventional cancer therapies, e.g. chemotherapy. Understanding both the malignant

roles of antigens and antibodies in the body’s immune response including the involvement of plasma cells, macrophages and antigen-presenting cells. The specific immune response relies on the lymphocytes, of which there are two main kinds, each with a number of sub-types.

They alert the immune system to the…

However, infection can develop when bacteria are trapped at the end of the venous loops beneath the epiphyseal, where phagocytic cells are absent to remove the invasion of the causative…
