when the host dies all it nutrients will go too and the parasite will get nothing so it will die if it doesn't get a new host
Attachment: Pathogen attaches to host cells. Invasion: Pathogen enters host cells and starts to replicate. Evasion: Pathogen evades host immune response. Spread: Pathogen spreads to other tissues and host organisms. Damage: Pathogen causes damage to host tissues and organs.
An avirulent pathogen is a pathogen that is unable to cause disease in its host. This may be due to mutations that have reduced its ability to infect or harm the host, making it less pathogenic compared to a virulent pathogen.
A pathogen (being something living from the goodness a body example: a tic living from a dog) 3 ways it can effect the host is: * disease of the host as the pathogen carried disease. * malnutrition of the host as the host can become weak due to the pathogen surviving from the hosts body. Example would be iron deficiency in the host, due to the pathogen using the hosts blood to live on * finally death of the host.
A pathotype is a specific subset of a pathogen that has a specific pathogenicity on a specific host. For example, one pathotype of a virus may have no effect on you, but can kill your cat.
The pathogen can be transferred to the host in a number of ways, from contact to the transfer of bodily fluids. If someone sneezes that can be a way of contracting the pathogen in the air, for you may breathe it in. There are also waterborne diseases.
vector
yes
One needs a pathogen , a host and an environment conducive for the pathogen to infect the host.
True Pathogen- are capable of causing disease in healthy persons with normal immune defenses ex. influenza virus, plague bacillus, and ect Opportunistic pathogen- cause disease when the host's defenses are compromised or when they grow in part of the body that is not natural to them
Infection
What are the 4 steps of pathogenesis?" 1-contect the host 2-infected the host 3-evide the host immune system 4-damage the host cell by physical or by mechanical.
A host of a disease is an organism that serves as a habitat for a pathogen to grow and reproduce. The pathogen can cause harm to the host by causing disease symptoms. In the context of infectious diseases, humans can serve as hosts for various pathogens like bacteria, viruses, and parasites.
