Notes on Infectious Diseases

An Infectious illness ¦ Is a disease that is baffled by the Invasion of a armament by agents whose activities harm the legionss wavers (That is, they experience disease) and back end be inherited to other individuals (that is, they atomic number 18 polluteious).\n\nPathogens: Microorganisms that are capable of causing disease. around microorganisms do not cause disease. Many probably exit some protection against bad microorganisms because thyme effectively compete with the nocent organisms. \n\nWorst case scenario, twain contagious and virulent. \n\nIn state to cause disease, pathogens must be able to enter the host body. They must adhere to detail host cells, invade and annex host tissues, and inflict impairment on those tissues. Some do damage at their stop consonant of entry, others travel to other separate of the host. Some reside and suppurate in body grippeids uniform blood or lymph, betwixt cells of the body tissues or wrong cells.\n\nMicrobes that C ause Infectious Diseases: at that place are 4 major(ip) types of infectious agents:\n: bacteria\n: Viruses \n: fungus kingdom\n: Parasites\n: Protozoa\n: Helminths\n\nBACTERIA:\n: bacterium are unicellular prokaryotic organsims with no organized informal membranous structures. Their genomes are circular, double-stranded DNA. \n\nbacteria come in many a(prenominal) shapes \n:Bacillus (rod shaped)\n:coccus (spherical) (strep throat)\n:spirilla (helical rods) \n\nBacteria cause disease in a strain of ways:\n:Bacteria can damage cells and disrupt tissue function as they jump\n:Many bacteria flummox toxins\n\nVIRUSES\n: Microbiologist shake 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 sick\n\nViral structure varies\n\nAdenovirus- causes frozen\nInfluenza virus- cause flu\n\nViruses cause disease by disrupting normal cell function..\n-They d o this in a multifariousness of ways\n-Unlike most bacteria (not all), viruses act inside cells)\n\nBacteria is treat...
