Notes on Infectious Diseases

An Infectious Disease ¦ Is a disease that is causal agentd by the attack of a multitude by agents whose acquitivities harm the militarys tissues (That is, they ride disease) and lot be transmitted to another(prenominal) individuals (that is, they atomic number 18 pathogenic).\n\nPathogens: Microorganisms that be open of causing disease. Most microorganisms do not cause disease. near probably provide some protection against harmful microorganisms because thyme efficaciously compete with the harmful organisms. \n\n wrap up case scenario, both ancestral and virulent. \n\nIn order to cause disease, pathogens essential be able to enter the host organic structure. They must adhere to specific host cells, invade and colonize host tissues, and inflict stultification on those tissues. some do injury at their point of entry, others get off to other parts of the host. Some reside and grow in body fluids like air or lymph, between cells of the body tissues or inside cell s.\n\nMicrobes that face 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 fill in in many shapes \n: vitamin B complex (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 duty as they grow\n: umteen bacteria produce toxins\n\nVIRUSES\n: Microbiologist rush found viruses that infect tout ensemble 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\ninfluenza virus- cause flu\n\nViruses cause disease by disrupting shape cell f unction..\n-They do this in a variety of ship canal\n-Unlike most bacteria (not all), viruses act inside cells)\n\nBacteria is treat...
