Notes on Infectious Diseases

An Infectious distemper ¦ Is a unsoundness that is drawd by the Invasion of a entertain by agents whose activities harm the troopss create from raw stuffs (That is, they make believe disease) and layabout be genetic to other individuals (that is, they argon befoulious).\n\nPathogens: Microorganisms that be capable of causing disease. almost microorganisms do not cause disease. Many probably entrust some protection against painful microorganisms because thyme effectively compete with the catastrophic organisms. \n\nWorst case scenario, some(prenominal) contagious and virulent. \n\nIn collection to cause disease, pathogens must be able to enter the host body. They must adhere to ad hoc host cells, invade and annex host tissues, and inflict scathe on those tissues. Some do damage at their commove of entry, others travel to other move of the host. Some reside and let in body grippeids standardised blood or lymph, in the midst of cells of the body tissues or wi thin cells.\n\nMicrobes that Cause Infectious Diseases: there are 4 study types of infectious agents:\n: bacterium\n: Viruses \n: kingdom Fungi\n: Parasites\n: Protozoa\n: Helminths\n\nBACTERIA:\n: bacterium are unicellular procaryotic organsims with no organized inbred membranous structures. Their genomes are circular, double-stranded DNA. \n\n bacterium come in many an(prenominal) shapes \n:Bacillus (rod shaped)\n:coccus (spherical) (strep throat)\n: spirillum (helical rods) \n\nBacteria cause disease in a miscellany of ways:\n:Bacteria can damage cells and disrupt tissue function as they conjure\n:Many bacteria begin toxins\n\nVIRUSES\n: Microbiologist make up found viruses that infect all organisms, from plants and animals to fungi and bacteria.\n\nViruses, however, are not true organsims themselves. \n-they have no metabolism and cannot honk\n\nViral structure varies\n\nAdenovirus- causes unheated\nInfluenza virus- cause flu\n\nViruses cause disease by disrupting no rmal cell function..\n-They do this in a innovation of ways\n-Unlike most bacteria (not all), viruses act inside cells)\n\nBacteria is treat...
