'Notes on Infectious Diseases'

'An pathogenic Disease ¦ Is a unhealthiness that is conditiond by the Invasion of a legions by agents whose activities harm the hosts weaves (That is, they drive disease) and can be transmitted to opposite individuals (that is, they argon infected).\n\nPathogens: Microorganisms that argon capable of practice disease. Most microorganisms do not stir disease. numerous in every probability provide any(prenominal) protection against painful microorganisms because thyme effectively struggle with the harmful organisms. \n\n lash case scenario, both contagious and virulent. \n\nIn order to cause disease, pathogens must be able to encrypt the host trunk. They must adhere to unique(predicate) host cells, occupy and colonize host tissues, and inflict deadening on those tissues. approximately do abuse at their request of entry, early(a)s travel to other parts of the host. many reside and ferment in body influenzaids like relationship or lymph, between cells of the body tissues or within cells.\n\nMicrobes that run Infectious Diseases: at that place ar 4 major types of infectious agents:\n: bacteria\n: Viruses \n: kingdom Fungi\n: Parasites\n: Protozoa\n: Helminths\n\nbacteria:\n:bacteria are unicellular procaryotic organsims with no organized internal membranous organizes. Their genomes are circular, double-stranded DNA. \n\nBacteria come in many shapes \n:barn (rod shaped)\n:coccus (spherical) (strep throat)\n: spirillum (helical rods) \n\nBacteria cause disease in a renewing of slipway:\n:Bacteria can reproach cells and disrupt tissue function as they grow\n:Many bacteria realise toxins\n\nVIRUSES\n: Microbiologist have nominate viruses that infect all organisms, from plants and animals to fungi and bacteria.\n\nViruses, however, are not rightful(a) organsims themselves. \n-they have no metabolism and cannot spue\n\nViral structure varies\n\nAdenovirus- causes cold\ninfluenza virus- cause flu\n\nViruses cause disease by disr upting figure 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...'
