Notes on Infectious Diseases

An Infectious Disease ¦ Is a disease that is reachd by the usurpation of a drove by agents whose turnivities harm the militarys tissues (That is, they get along disease) and preserve be transmitted to opposite individuals (that is, they atomic number 18 infected).\n\nPathogens: Microorganisms that are cap competent of causing disease. Most microorganisms do not cause disease. many probably provide somewhat protection against harmful microorganisms because thyme efficaciously compete with the harmful organisms. \n\n blister case scenario, both transmissible and virulent. \n\nIn order to cause disease, pathogens must be able to enter the host automobile trunk. They must adhere to specific host cells, invade and colonize host tissues, and inflict constipation on those tissues. about do revile at their point of entry, others jaunt to other parts of the host. Some reside and grow in body fluids like rake or lymph, between cells of the body tissues or inside cells.\n \nMicrobes that designer Infectious Diseases: There are 4 major types of infectious agents:\n: bacteria\n: Viruses \n: Fungi\n: Parasites\n: phylum Protozoa\n: Helminths\n\nBACTERIA:\n:Bacteria are unicellular prokaryotic organsims with no organized internal membrane-forming structures. Their genomes are circular, double-stranded DNA. \n\nBacteria descend in many shapes \n: vitamin B (rod shaped)\n:coccus (spherical) (strep throat)\n:spirillum (helical rods) \n\nBacteria cause disease in a variety of slipway:\n:Bacteria can damage cells and disrupt tissue social occasion as they grow\n: galore(postnominal) bacteria produce toxins\n\nVIRUSES\n: Microbiologist digest found viruses that infect totally organisms, from plants and animals to fungi and bacteria.\n\nViruses, however, are not true organsims themselves. \n-they have no metabolism and cannot reproduce\n\nviral structure varies\n\nAdenovirus- causes cold\n flu virus- cause flu\n\nViruses cause disease by disrupting regul ation cell function..\n-They do this in a variety of ship canal\n-Unlike most bacteria (not all), viruses act inside cells)\n\nBacteria is treat...
