For instance, bacteria is often a disease-causing agent, but many types of bacteria are harmless or even required to maintain life. These bacteria are thus not considered disease-causing agents. The common categories of disease-causing agents include: Viruses Bacteria Protozoa Fungi Parasitic worms ...
On Antibodies Substances foreign to the body, such as disease-causing bacteria and viruses and other infectious agents, are recognized by the body s immune system as invaders. Our natural defenses against these infectious agents are antibodies, proteins that seek out the antigens (抗原)and help ...
Disease-causing agents, such as viruses, usually have specific targets. Some viruses affect only humans; other viruses live in or affect only animals. Problems start when animal viruses are able to infect people as well, a process known as zoonosis. When an animal virus passes to a human, ...
Though evolution has helped us become resistant to some of these disease-causing agents, these pathogens have also found new ways of infecting us. What is even scarier is that there are viruses and bacteria that have been trapped in ice and permafrost for thousands of years, and these long-...
First, we assessed whether P1’s cells were able to cope with various DNA lesions produced by distinct genotoxic agents. P1’s SV40-transformed fibroblasts, similar to cells from an ATM-deficient patient, exhibited a strong sensitivity to ionizing radiation (IR), suggesting a DNA repair defect ...
