What are bacteria that live in or on plant and animal tissue without harming it called?
Bacteria that live in or on plant and animal tissue without harming it are called commensal bacteria. These bacteria benefit from the environment provided by the host without causing harm or benefiting the host in return.
Can the stage of bradyzoites that form cysts within host cells allow bradyzoites to destroy host tissue and cause disease?
Bradyzoites, the dormant stage of the parasitic protozoan Toxoplasma gondii, typically form cysts within host cells, allowing them to evade the host's immune response. While they are primarily associated with chronic infection rather than acute tissue destruction, the presence of these cysts can lead to inflammation and damage to host tissues, especially if the immune system is compromised or if cysts rupture. In some cases, the immune response to these cysts can also contribute to tissue damage, resulting in disease symptoms. Therefore, while bradyzoites themselves do not directly destroy tissue, their presence and the resultant immune response can contribute to disease pathology.
How does protozoa cause diseases?
Protozoa variants, such as amoebiasis cause diseases by secreting enzymes which absorbed by the tissue of the host.
What does the intestinal fluke eat?
Intestinal flukes primarily feed on the host's blood, tissue fluids, and cells found in the intestines. They attach themselves to the intestinal walls using specialized structures to feed on nutrients and cause damage to the host's tissue.
Pathogens directly attack human tissue?
Pathogens such as bacteria, viruses, and fungi can directly attack human tissue by invading and replicating within the cells or tissues of the body. This invasion can lead to damage of the host tissue, triggering an immune response and causing symptoms of infection.
When is Graft versus host disease most likely to occur?
A Graft versus host disease is most likely to occur or happen, when a tissue transplant does not take because the body fights the transplanted tissue. The recipient or host body rejects the tissue and attacks it.
What is A pathogen's entry into a host's body tissue called?
Infection
What is the difference between biotrophs and necrotrophs?
Biotrophs are pathogens that rely on living host tissue to complete their life cycle, while necrotrophs feed on dead host tissue. Biotrophs keep the host alive for an extended period by suppressing host defenses, while necrotrophs kill host cells to acquire nutrients.
What is the function of haustoria in powdery mildew?
Haustoria are a specialized hyphae in parasitic fungi that invade inter (in) and intra (around) cellular tissue in the host of the parasite. The purpose of the haustoria is to draw metabolites (energy) from the host tissue for the parasites growth and reproduction.
An immune response to a tissue graft will differ from an immune response to a bacterium because?
MHC molecules of the host may stimulate rejection of the graft tissue :]
What is a short definition of parasitism?
A parasite spends most of its life in or on the tissue of a host which would is very harmful to it.
What are bacteria that live in or on plant and animal tissue without harming it called?
Bacteria that live in or on plant and animal tissue without harming it are called commensal bacteria. These bacteria benefit from the environment provided by the host without causing harm or benefiting the host in return.

Do tapeworms eat intestinal contents intestinal bacteria red blood cells or host tissue?
The take up the intestinal contents thereby reducing the amount of food for the host animal.
