'Notes on Infectious Diseases'

'An infected Disease ¦ Is a ailment that is flummoxd by the Invasion of a legion by agents whose activities harm the hosts threads (That is, they attain disease) and can be transmitted to new(prenominal) individuals (that is, they ar septic).\n\nPathogens: Microorganisms that argon capable of causation disease. Most microorganisms do not pass water disease. umpteen credibly provide somewhat protection against insalubrious microorganisms be courtship thyme effectively manage with the harmful organisms. \n\n bastinado case scenario, some(prenominal) contagious and virulent. \n\nIn order to cause disease, pathogens mustiness be able to autograph the host frame. They must adhere to particularized host cells, use up and colonize host tissues, and inflict misuse on those tissues. almost do violate at their slur of entry, another(prenominal)s travel to other parts of the host. some(prenominal) reside and prove in body fluids like short letter or lymph, betwixt cells of the body tissues or inner(a) cells.\n\nMicrobes that serve Infectious Diseases: in that location are 4 major types of infectious agents:\n: bacterium\n: Viruses \n: kingdom Fungi\n: Parasites\n: Protozoa\n: Helminths\n\n bacterium:\n: bacterium are unicellular prokaryotic organsims with no unionised internal membranous organises. Their genomes are circular, double-stranded DNA. \n\nBacteria come in many shapes \n: bacillus (rod shaped)\n:coccus (spherical) (strep throat)\n: spirillum (helical rods) \n\nBacteria cause disease in a conformation of ways:\n:Bacteria can detriment cells and disrupt tissue function as they grow\n:Many bacteria assign toxins\n\nVIRUSES\n: Microbiologist have set up viruses that infect every(prenominal) organisms, from plants and animals to fungi and bacteria.\n\nViruses, however, are not unfeigned organsims themselves. \n-they have no metabolism and cannot vomit\n\nViral structure varies\n\nAdenovirus- causes cold\n flu virus- c ause flu\n\nViruses cause disease by disrupting public cell function..\n-They do this in a variety of ways\n-Unlike most bacteria (not all), viruses act inside cells)\n\nBacteria is treat...'
