What are Pathogens?
A large variety of entities exist. Some can thrive and grow inside the host. If the organism can inflict infectious diseases, it is an infectious agent. Manual infectious agents that can cause illness and infection are referred to as pathogens.
Classification of Pathogens
Pathogens are classified into four main categories concerned with the classes of pathogenicity relying on general risk analysis and assessment available under the purview of the present practical and theoretical frameworks. These include:
One of the below criteria has to be covered by the microbial species like:
- They should not be part of an identified group of disease-causing agents in animals or humans.
- They had proven to be safe in the past history under conditions, without any sort of restrictions physically despite taking into account that species have a difference in virulence between strains within them.
- The species that belong to one of the below classes, but a particular group of the chain might have fewer genes that could create pathogenicity in animals and humans. The species of a particular chain might be put in an exceptional position depending on the degree of attenuation.
This would imply that out of categories 2,3 and 4 species, the certain chain would be downgraded to a class.
- Both in vivo and in vitro testing, the non-pathogenicity of the species has been demonstrated authoritatively.
Species which spread diseases in humans or animals, might not spread to the humans and that has necessary prophylaxis or therapy.
Species which cause serious disease in humans, spread to the humans while having the necessary prophylaxis or therapy.
Species that cause serious human disease, which is likely to disseminate in the human population and for which no adequate prophylaxis or therapy exists.
