Viruses can't be seen in host tissues.
Viruses can't be cultured in order to be inoculated into a new host.
The male reproductive organs are in one individual, and the female substitute a laboratory animal for the third step of Koch's postulates.
Some viruses can not cause cancer.
Answers will change.
There is a possible mechanism that can be seen in an abnormal tissue.
The study of the cause of a disease is called eviology, while the manner in which the disease develops is called pathogenesis.
There is a change in a state of health.
Sometimes a disease can be caused by an infection, but not always.
Hemolysins lyse red blood, whereas a noncommunicable disease is not transmitted.
neutrophils and macrophages are destroyed from one host to another by leukocidins.
One of the organisms benefits and the other is unaffected, as shown by the example of coryne kinases breaking down a clot in the eye.
Iron is useful for the human host.
IgA antibodies protect warmth in the large intestine, and IgA proteases destroy them.
Would stop the growth ofbacteria.
Patients were mitted to by endotoxin.
The hospital staff, visitors, and other patients are Gram 2 of infections.
The host needs a chemical or environment that is essential.
Commensal organisms are not essential.
Incubation period, prodromal period, period of illness, period of decline, period of convalescence.
Pathogenic fungi do not have a specific virulence factor.
Host tissues are destroyed by Protozoa and helminths.
Some can remain in a cell for a long time.
Encapsulatedbacteria can grow.
The acidic environment in female is related to their virulence.
Inflammation is the body's response to injury.
Interferons are involved in defense.
There are self-antigens in the major histocompatability complex.
There are reactions with MHC II and MHC I.
Endotoxin causes cell lysis by binding C3b.
This can result in free cell wall fragments, which bind more C3b, resulting in C5-C9 damage.
Oxygen products can be toxic.
The activated complement causes hemolysis when the recipient's antibodies combine with the donor's.
CTLs destroy targets on contact.
The immune response is suppressed by TR cels.
A response by other cels is initiated by the release of cytokines.
Kill or stop the growth ofbacteria.
The resistance to infections obtained through adaptive immunity leads to the production of B cel s with different genes.
The person recovered because he or she produced an immunity against the pathogen.
The memory response will protect the per or individuals from certain diseases that are not dependent on the pathogen.
The immune system is due to antibodies.
The immunity is due to T cel s.
If the disease is caused by a live, avirulent virus, it can be caused by injection of antibodies or by changing its state.
The whole-agent killed thebacteria.
Subunit is an inactivated toxin.
T-independent antigens can cause an immune response.
The CD8 antigen is present in the nucleus acid C cels.
There are 5 different types of Immunoglobins and 5 different types of TCRs.
This procedure can be used to detect the presence of mycotic or helminthic infections.
