IMMUNOLOGY

Detailed explanation-1: -Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions. Pathogens of all classes must have mechanisms for entering their host and for evading immediate destruction by the host immune system. Most bacteria are not pathogenic.

Detailed explanation-2: -What are pathogens? Pathogens include viruses, bacteria, fungi, and parasites that invade the body and can cause health issues. Anthrax, HIV, Epstein-Barr virus, and the Zika virus, among many others are examples of pathogens that cause serious diseases.

Detailed explanation-3: -Pathogenic organisms have acquired genes that encode proteins that interact specifically with particular molecules of the host cells. In some cases, such as the B.

Detailed explanation-4: -Pathogens communicate with human cells through physical interactions with various human proteins on the surface of the cell and within the interior of the cell. These interactions allow the pathogen to enter the host cell, manipulate important cellular processes, multiply, and invade other cells.

Detailed explanation-5: -Pathogenesis-related proteins, often called PR proteins, are a structurally diverse group of plant proteins that are toxic to invading fungal pathogens. They are widely distributed in plants in trace amounts, but are produced in much greater concentration following pathogen attack or stress.

Detailed explanation-6: -Pathogens are microorganisms that have the potential to cause infectious diseases. Viruses, bacteria, protozoans and fungi are all potential pathogens.

Detailed explanation-7: -common cold. flu. meningitis. warts, including genital warts. oral and genital herpes. chickenpox/shingles. measles. viral gastroenteritis, including norovirus and rotavirus. More items •03-Apr-2019
