It requires the attributes of transmissibility or communicability from one host or reservoir to a fresh host. The typical fungal spore size is. Ability of the host to prevent the infection or to decrease parasite load.

Commensals and opportunistic pathogens lack this inherent ability to cause disease. Since many protists live as commensals or parasites in other organisms and these relationships are often species-specific there is a huge potential for protist diversity that matches the diversity of hosts. This assignment will explain how the structures and characteristics of microorganisms are used to classify them.

The importance of the. Another name for a pathogen is an infectious agent as they cause infectionsAs with any. There are several kinds of unicellular organisms such as bacteria protozoa algae fungi etc.

That is called as Pathogenicity of the organism. It multiplies within liver cells enters the bloodstream and ruptures RBCs. Fungi are eukaryotic organisms that can function as pathogens.

A pathogen brings disease to its host. Virulence genes are frequently clustered together either in groups on the bacterial chromosome called pathogenicity islands or on extrachromosomal virulence plasmids Figure 25-5. The cultural characteristics and animal pathogenicity of an atypical acid-fast organism which causes human disease.

This ability represents a genetic component of the pathogen and the overt damage done to the host is a property of the host-pathogen interactions. The parasite attacks the liver and RBCs.
