My idea of a perfect pathogen would be one that can survive and persist long enough to cause infection and to be transmitted to the next host. And this multiplicity of behaviours depends at least on the generation of diverse cell surface structures and phenotypic variants to evade the host immune response. One such strategy to achieve this in bacteria is antigenic variation‚ a strategy also employed by viruses‚ fungi‚ and protozoa‚ which all face similar challenges when infecting a host‚ that is

Prion diseases‚ also known as transmissible spongiform encephalopathies (TSEs)‚ are neurodegenerative conditions that not only effect humans‚ but animals as well. Neurodegenerative have to do with damages that occur in neurons‚ which could even lead to neuron death. Neurons are what make up the nervous system; This includes the brain and spinal cord. Knowing this‚ the disease is very affective and could cause damage to the body as far as death. Prions are found in everyone’s bodies. There is a gene
