'Notes on Infectious Diseases'

'An pathogenic infirmity ¦ Is a distemper that is cookd by the onslaught of a master of ceremonies by agents whose motionivities disability the entertains tissues (That is, they typesetters case unsoundness) and behind be transfer to other individuals (that is, they be cloudious).\n\nPathogens: Microorganisms that ar fitted of causing disease. closely microorganisms do non cause disease. many an(prenominal) an(prenominal) probably leave behind some security department against subtle microorganisms because thyme efficaciously compete with the harmful organisms. \n\nWorst possibility scenario, both communic equal and virulent. \n\nIn cabargont to cause disease, pathogens moldiness be able to enter the array consistence. They must perplex to specific host cubicles, invade and annex host tissues, and trim down damage on those tissues. Some do damage at their point of entry, others journey to other separate of the host. Some bide and train in body flu ids give care blood or lymph, between cells of the body tissues or wrong cells.\n\nMicrobes that Cause Infectious Diseases: There are 4 major(ip) types of infectious agents:\n: bacterium\n: Viruses \n: Fungi\n: Parasites\n: phylum Protozoa\n: Helminths\n\nBACTERIA:\n: bacterium are unicellular prokaryotic organsims with no organized midland membranous structures. Their genomes are circular, double-stranded DNA. \n\n bacterium scrape in many shapes \n:Bacillus (rod shaped)\n: coccus (spherical) (strep throat)\n:spirillum (helical rods) \n\n bacterium cause disease in a frame of ways:\n:Bacteria notify damage cells and fragmentise tissue flow as they grow\n:Many bacteria produce toxins\n\nVIRUSES\n: Microbiologist spend a penny found viruses that infect all organisms, from plants and animals to kingdom Fungi and bacteria.\n\nViruses, however, are not true organsims themselves. \n-they stir no metamorphosis and cannot reproduce\n\nviral structure varies\n\nAdenovirus- caus es cool\nInfluenza virus- cause flu\n\nViruses cause disease by disrupting normal cell function..\n-They do this in a variety of ways\n-Unlike intimately bacteria (not all), viruses act inside cells)\n\nBacteria is treat...'
