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

Agriculture itself could scarcely have evolved eons ago without the versatile pig‚ yet fewer and fewer farmers raise even a single pig these days because there comes a time where they cannot control the situations when problems occur such as spreading of diseases to their animals. The problem of that is not on the animals‚ but on the operations and maintenance of human resources like the piggeries. Pigs gets contaminated through direct or indirect contact or by eating uncooked slops or kitchen scraps or

There are a number of different ways the body protects itself against pathogens. Pathogens are microorganisms that cause disease. Such as harmful bacteria‚ viruses and fungi‚ many mechanisms occur in the human body to help keep it healthy and avoid any unknown pathogens from invading the body. The human body protects itself effectively against small bacterial and viral germs that can cause a disease‚ it is easy for pathogens to settle down and multiply due to the nutrients provided inside the human
