The Worlds Fight Against Microbes Essay -- Research Papers Science Bi

The Worlds Fight Against MicrobesMany infectious diseases that were nearly eradicated from theindustrialized world, and impertinently emerging diseases are now breaking out all everyplacethe world due to the misuse of medicines, such as antibiotics and antivirals,the destruction of our environment, and nearsighted political action and/orinaction.Viral hemorrhagic febricitys are a group of diseases caused by viruses fromfour distinct families of viruses filoviruses, arenaviruses, flaviviruses, andbunyaviruses. The usual innkeepers for most of these viruses are rodents orarthropods, and in some viruses, such as the Ebola virus, the natural host isnot cognize. All forms of viral hemorrhagic fever begin with fever and muscleaches, and depending on the particular virus, the disease fag end progress until the diligent becomes deathly ill with respiratory problems, severe bleeding, kidneyproblems, and shock. The severity of these diseases can browse from a mildillness to death (CDC I).The Ebola virus is a subdivision of a family of RNA (ribonucleic acid)viruses known as filoviruses. When these viruses are magnified some(prenominal) thousandtimes by an electron microscope they have the appearance of big filaments orthreads. Filoviruses can cause hemorrhagic fever in human and animals, andbecause of this they are extremely hazardous. Laboratory studies of theseviruses must be carried out in special maximum containment facilities, such asthe Centers for Disease Control (CDC) in Atlanta, Georgia and the United StatesArmy Medical Research Institute of infective Diseases (USAMRIID), at FortDetrick in Frederick, Maryland (CDC I,II).The Ebola hemorrhagic fever in humans is a severe, systemic illnesscaused by infection with Ebola virus. on that point are four subtypes of Ebola virus(Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast, and Ebola-Reston), which are notjust variations of a single virus, but four distinct viruses. Three of thesesubtypes are known to cause di sease in humans, and they are the Zaire, Sudan,and Ivory Coast subtypes. appear of all the different viral hemorrhagic feversknown to occur in humans , those caused by filoviruses have been associated withthe highest case-fatality rates. These rates can be as high as 90 percent forepidemics of hemorrhagic fever caused by Ebola-Zaire virus. No vaccine exists toprotect from... ... Yet a bacterium can kill a whale ... Such is the adaptability andversatility of microorganisms as compared with humans and separate so calledhigher organisms, that they will doubtless continue to colonise and variegate theface of the Earth long after we and the rest of our cohabitants have left over(p) thestage forever.
