Please do discussion post on Tetanus- The central nervous system is remarkably resistant to infection, largely because of a barrier between the blood circulation and the nervous tissue, referred to as the blood-brain barrier. Although not common, there are ties where a pathogen invades the nervous system and causes disease. These infections can be caused by bacteria, viruses, fungi, protozoans,or prion-associated. Address the following criteria in your main response to this week’s discussion: Choose ONE disease that is caused by a bacteria, virus, fungus, protozoan or prion discussed in your textbook. Describe the pathogen associated with the disease, how the pathogen leads to disease, and how it enters the body. Your discussion should also discuss the major signs and symptoms of the disease and the treatment for the infection. Then, provide a case study highlighting your chosen disorder.
