Bacterial Pathogenesis

ABSTRACT If a micro existence either harms or lives at the write off of a nonher organism, it is c aloneed a parasitical organism and the relationship is called the parasitism. In this relationship the infected organism is referred to as boniface. Those organisms capable of do distemper argon called pathogens. distemper is any change in the forces from a healthy to an unhealthy,abnormal statein which stir up or all of the hosts body is not capable of carrying on its normal functions. The steps of the infecting plow involving bacterial disease commonly include the following : * The bacterium is genetic to suitable host , * Attaches to and/or colonises the host, * Grows and multiplies inside or on the host * Interferes with or impairs the normal physiological activities of the host During coevolution with homo hosts,pathogenic bacteria have evolved interlinking signal transduction pathways to regulate the genes required for virulence. The genes that encode virulence factors are often located on large segments of DNA within bacterial genome.called pathogenecity islands that carry genes prudent for virulence. Two distinct categories of disease can be accepted based on the eccentric bacteria play in disease causing process : * Infections(invasion and growth) * intoxications .

Toxins produced by pathogenic bacteria are either exotoxins or endotoxins. Viruses and bacteria are continuously evolving and producing unique mechanisms that enable them to fudge the hosts arsenal of defences. The modern era of chemotherapy began with cap ital of Minnesota Ehrlischs organize on dru! gs against affrican sleeping sicknessand syphills. Other pioneers were Gerhard Domagk, horse parsley Flemming, Howerd Florey etc. Many infectious diseases are treated with chemotherapeutic agent, much(prenominal) as antibiotics, that inhibit or kill the pathogen while harming the host as little as possible. Ideally, antimicrobic agents disrupt microbial processes or structures that differ from...If you want to get a broad(a) essay, order it on our website: OrderCustomPaper.com
