Well, let us know about one world Host. According to its definition, host, also known as parasitifer, refers to organisms that provide living environment for parasites including parasites and viruses. During the nature, there are a lot of hosts, and at the same time there are a lot of parasites by this time, i will post this article to show what is host, and other concrete information about host.
Explanation of word
The host, including human and animals, is a creature that can provide nutrients and places to pathogens. Some pathogens (such as Bacterium typhi-abdominalis and Bacillus dysenteriae) only infect people, while some pathogens may have many hosts. For example, rabies virus can be parasitic in dogs, wolves, cats and other animals. There are many ways for hosts to discharge pathogens. It is common in respiratory tract, digestive tract, skin and blood.Chick Here
Types of Host
The Definitive Host is a parasitic organism or a parasitic species at the stage of sexual reproduction. This kinds of hosts usually provide a long-term stable parasitic environment for parasites including nutritional and biological protection.
Alternate hosts, are also called Intermediate hosts, are parasitic species of parasitic organisms such as larvae, or the species which live in host with asexual stages. Such hosts can also provide nutrition and protection for the parasites, but the parasites can not grow into adults in the intermediate host, and the parasites send themselves to the definitive host through the intermediate host as a vector.
Abnormal intermediate host
In some special cases, the larvae of parasites enter into the definitive host directly, which becomes an “abnormal intermediate host”. For example, Taenia solium in some cases turns human into its abnormal intermediate host.
