Discuss the involvement of bacteria in the development and treatment of cancer.

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. Nonetheless, bacteria, bacterial toxins or spores are being considered in alternative cancer therapy. 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

Essay about Biology: Immune System and Macrophage Macrophages Function

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. Both types respond to foreign (non-self) antigens, such as proteins on the surface of bacteria and viruses. Macrophages are also involved, engulfing bacteria and displaying the non-self antigens. They alert the immune system to the…

Osteomyelitis Case Studies

organisms, high virulence of an organism, bone injury may cause the affected bone to become vulnerable to bacterial colonization. Generally, bacteria that gain entrance to the bone are incapable of causing an infection due to the inflammatory response that prevents bacteria from spreading in the medullary cavity. 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…

Tumor Immunology Research Paper

Tumor Immunology Tumor express antigens that are recognized as foreign by the immune system of the tumor-bearing host. Immune responses normally fail to prevent the growth of tumors. The immune system can be activated by an external stimuli to effectively kill tumor cells and eradicate tumors. Immune responses frequently fail to prevent the growth of tumor. Tumor cells are derived from host cells, the rapid growth and spread of tumors and specialized mechanisms for evading host immune responses Tumor…
